from the environment.
4.L.1.3 Explain how humans can adapt their behavior to live in changing habitats.
4.L.1.4 Explain how difference among animals of the same population sometimes give individuals an
advantage in surviving and reproducing in changing habitats.
4.L.2 Understand food and the benefits of vitamins, minerals, and exercise.
4.L.2.1 Classify substances as food or non-food items based on their ability to provide energy and
materials for survival, growth and repair of the body.
4.L.2.2 Explain the role of vitamins, minerals and exercise in maintaining a healthy body.
Essential Question(s) for the Unit How do animals change and adapt in order to survive successfully within their habitats?
Pre-Assessment Opportunities A formative assessment probe called “Habitat Change” is available on page 143 of Uncovering Student
Ideas in Science Volume 2 (Blue Cover), by Page Keeley et al. The probe elicits students’ ideas about
adaptation and is designed to reveal whether students think individuals intentionally change their
physical characteristics or behaviors in response to an environmental change. Explain to students that
the divo is an imaginary organism however; the challenges it faces, due to drastic change in its
environment, would produce similar responses from real organisms.
Notes about the Animal Studies Unit Students will build three different habitats and observe three different animals – dwarf African frogs,
fiddler crabs, and millipedes. It’s best to stagger the shipment of the animals so they do not arrive at the
same time. As frogs are observed first, they should be shipped first, followed by fiddler crabs, and finally
millipedes. Because animals will need care and feeding, it is best to have them arrive no more than a day
or two before students build the habitats. Animal delivery should not be scheduled prior to a long break.
You may run out of room in the classroom to keep all three animal habitats going at one time. It is
acceptable to complete the work needed on each animal and dismantle habitats as needed.
Animals may NOT be released into the wild or given to students to take home. Please visit the
Elementary Science Wiki for additional information about animal care and opportunities to share living
organisms.
Animal Studies Page 4
Lesson 1 – Pre-Unit Assessment: Thinking about Animals and Their Homes (STC Animal Studies Lesson 1) Students complete pre-unit assessment activities and a formative assessment probe called “Habitat Change.” Students discuss what they know about animals and their habitats. *The millipede should be a familiar animal as it was observed and studied in the Organisms unit in 1st grade.
Clarifying Objectives
4.L.1.1 Give examples of changes in an organism’s environment that are beneficial to it and some that
are harmful.
4.L.1.2 Explain how animals meet their needs by using behaviors in response to information received
from the environment.
Focus Question(s)
What do we know about frogs, crabs, and millipedes?
How do scientists study animals?
Activity Guiding Questions
Administer the formative assessment probe called “Habitat Change.”
Discuss the ways students think scientists learn about animals.
In their science notebook, students should record individually what they already know about frogs, crabs, and millipedes.
Discuss their thoughts as a group while you record their ideas on three separate pieces of chart paper—one chart per animal.
Compare and contrast how these animals are similar and different from each other. This can be done as a list or as a triple Venn diagram.
Students then discuss how and why scientists study animals.
Give a general overview of what was discussed today and answer any questions the students might have to clarify the concepts covered in the lesson.
The final activity (which may be assigned as homework) is the completion of Record Sheet 1A. Students will use their completed sheet in the next lesson.
In what ways do you think frogs and crabs are similar? Frogs and millipedes? Crabs and millipedes?
In what ways do you think frogs and crabs are different? Frogs and millipedes? Crabs and millipedes?
In what ways do you think each animal’s life is similar? Different?
Where do you think scientists study animals?
What are some ways you think scientists study animals?
Where can you go in your area to observe animals in their natural homes?

Science Content Words
Use these terms when teaching the lesson:
biosphere regions of Earth (including land, water, and air) that support life
biodiversity the numbers and kinds of organisms in a habitat
Integration Hints
Gather a selection of books about animals and habitats from your media center and create an “Animal
Studies” book box. Allow students to access these books during their independent reading time.
Science Notebook Helper
Have students divide a page in their science notebooks into four blocks. Label them “Frogs,”
“Crabs,” “Millipedes,” and “Comparing Frogs, Crabs, and Millipedes.” Students can use a “Think-
Pair-Share” technique when coming up with animal traits. Give them a few moments to
brainstorm on their own in their science notebooks, then pair up in their science groups to share
what they wrote. Students can add new ideas from their group members to their notebooks.
Groups can then take turns sharing their ideas in the whole-class setting. The shared ideas will
make up the class lists on the chart paper.
Record sheet 1-A can be stapled or pasted in the science notebook.
Assessment Opportunities
The Teacher Guide identifies Lesson 1 as a Pre-Unit Assessment opportunity.
The probe “Habitat Change” also serves as a formative assessment.
Animal Studies Page 6
Lesson 2 - Observing and Investigation Our Food (Alignment Lesson) Students observe and categorize their food intake. *This lesson is an introduction to food and food groups. These concepts will be studied further in the Investigating Human Body Systems unit in 5th grade. The goal of this lesson is for students recognize that human beings (also classified as animals) consume food for energy. When animals are brought into the classroom for observation, they will need to consume food for energy.
Clarifying Objectives
4.L.2.1 Classify substances as food or non-food items based on their ability to provide energy and
materials for survival, growth and repair of the body.
Focus Question(s)
Why is it important to eat a balanced diet and to exercise?
Activity Guiding Questions
Prompt students to respond to the question “Why is it important to eat a healthy selection of food?” as a quick write.
Prompt students to consider the cafeteria as a place to observe humans taking in food to provide energy for the rest of the day.
Invite students to consider how they might keep a record of everything they eat during lunch. The data collection could be a simple list or a table that lists the various food groups highlighted in the MyPlate (weblink available on CMAPP) guidelines.
After collecting data, students sort their food into groups according to the MyPlate guidelines and count the number of food items in each category.
Each student should contribute his/her data to create a class pie chart to represent the types of food consumed by the class. (A link to an online pie chart maker is available on CMAPP.)
Lead a discussion about the class data compared to MyPlate guidelines. Prompt students to think of ways to increase consumption of food underrepresented or ways to decrease foods overrepresented.
Ask students what questions they have now.
Where in our school is a good place to observe humans taking in energy to help fuel them for the rest of the day?
How might we get our class “plate” to look more similar to the MyPlate guidelines?
Why do you think eating according to the MyPlate guidelines is important?
Animal Studies Page 7
Prompt students to revisit their quick write and make any additions to capture their learning.
Science Content Words
Use these terms when teaching the lesson:
dairy All fluid milk products and many foods made from milk are considered part of this food group. Most Dairy Group choices should be fat-free or low-fat. Foods made from milk that retain their calcium content are part of the group. Foods made from milk that have little to no calcium, such as cream cheese, cream, and butter, are not. Calcium-fortified soy milk (soy beverage) is also part of the Dairy Group.
energy Energy exists in different forms but is neither created nor destroyed; it simply converts to another form
fruit Any fruit or 100% fruit juice counts as part of the Fruit Group. Fruits may be fresh, canned, frozen, or dried, and may be whole, cut-up, or pureed
grains Any food made from wheat, rice, oats, cornmeal, barley or another cereal grain is a grain product. Bread, pasta, oatmeal, breakfast cereals, tortillas, and grits are examples of grain products.
protein All foods made from meat, poultry, seafood, beans and peas, eggs, processed soy products, nuts, and seeds are considered part of the Protein Foods Group. Beans and peas are also part of the Vegetable Group.
vegetable Any vegetable or 100% vegetable juice counts as a member of the Vegetable Group. Vegetables may be raw or cooked; fresh, frozen, canned, or dried/dehydrated; and may be whole, cut-up, or mashed.
Integration Hints
Students sort and contribute individual data to create a class pie chart which shows the types of
food consumed by the class during lunch.
You might encourage students to keep a weekly food log to keep track of their food
consumption at breakfast, lunch, dinner, and snacks. Students could work on creating their own
pie chart to represent their food consumption.
The PE specialist at your school can speak to students about the importance of exercise.
Science Notebook Helper
Students keep a list or create a table to record the various types of food they consumed during a
lunch period. Students might also sketch the class pie chart (including labels) that was created to
represent class food consumption.
Animal Studies Page 8
Assessment Opportunities
Students respond in a quick write at the beginning and end of the lesson to the question: “Why
is it important to eat a healthy selection of food?”
Animal Studies Page 9
Lesson 3 - How Do Living Things Get Energy From Food? (Alignment Lesson) Students learn about calories and nutrients in food. *This lesson is an introduction to calories and nutrients. Students will explore these concepts further in the 5th grade Investigation Human Body Systems unit. The goal for this lesson is for students to begin thinking about the energy transfer from food to the body. The use of a calorimeter and related formulas help scientists quantify the amount of energy in calories. Students are not expected to memorize the formulas as they are abstract at the elementary level.
Clarifying Objectives
4.L.2.1 Classify substances as food or non-food items based on their ability to provide energy and
materials for survival, growth and repair of the body.
4.L.2.2 Explain the role of vitamins, minerals and exercise in maintaining a healthy body.
Focus Question(s)
How does the body get energy from food?
Activity Guiding Questions
Remind students to think about how they categorized foods in the previous lesson.
Guide and assist groups of students in writing their predictions in response to the focus question.
Lead a discussion on using calories and what happens to un-used calories.
Prompt students to brainstorm how a scientist might find out which nut – Brazilian, cashew, or peanut – has the most calories. Introduce a calorimeter as a tool scientists use to discover the calories in various foods. This information is transferred to the nutrition labels that we find on food and drink packaging.
Do a teacher demonstration on using the calorimeter (directions to construct a calorimeter are available on CMAPP) to find the calories of different nuts OR refer to the video “Calorimetry: Measuring Energy in a Peanut.” (a link to the video is available in CMAPP)
Convert data into calories and guide students record it into their data tables.
Lead a discussion on what this new information means and if all calories are created equal.
How does the body get energy from food?
How many minutes would we have to laugh in order to burn off a 100 calorie pack of chips?
What do you think will happen if you don't use up all the calories you consume?"
How can we find out which of these nuts has the most calories?
Are all calories created equal? In other words, if I get calories from a soda or from an apple, are the calories the same? Why or why not? [Calories from an apple come from natural sugars and various vitamins and minerals, while the calories in soda come from mainly sugar. Sometimes calories in sodas, potato chips, and other snack items are referred to as “empty calories” because they provide little nutritional benefit.]
Which would you eat? Why?
If one eats food with many calories, but no nutrients, what is the effect?
What does it mean to be a healthy eater?
Animal Studies Page 10
Guide the students in comparing the nutritional information of an apple and a soda.
Science Content Words

Students’ science notebook entries.
calorie the energy it takes to raise the temperature of 1 gram of water 1 degree Celsius. The important word to take away from this definition is ENERGY. Calories are ENERGY that fuel our bodies; much like gasoline fuels our cars. Without sufficient calories our heart would not beat, our lungs would not function, and our brain would not work. Many of us have no idea how many calories our body needs just to exist
diet The usual food and drink consumed by an organism (person or animal)
nutrition the scientific study of food and drink (especially in humans) and a source of materials to nourish the body.

Students will also begin a series of Venn diagram circles they will put together in a future lesson (See Teacher’s Guide for example).
Students will learn about the structure of frogs and make their initial observations of frog behavior.
Have a class discussion and question session about what the children have learned about the characteristics and habitat of a frog.
What happened when you put food in the tank?
Did both frogs respond to the food? What happened when you moved the food with the spoon?
How much food did the frogs eat?
Did the frogs eat from the surface or bottom of the habitat?
When do you think we should record observations about an animal?
How might we record observations?
Science Content Words
Use these terms when teaching the lesson:

Integration Hints
Students can practice narrative writing about habitat building or frog observation.
Students can create a “how-to” writing providing directions to build a frog habitat. The writing
can include a materials list and pictures/diagrams to promote understanding.
Science Notebook Helper
Once students complete building the habitat and before frogs are distributed to students,
prompt them to draw a frog in their science notebooks and label its parts. In the next lesson,
Observing the Frogs More Closely, students will create a more scientifically correct drawing of
the frog.
Assessment Opportunities
Teacher observation
Student entries in their science notebooks
Students complete a habitat to meet the dwarf frog’s basic needs.

advantage in surviving and reproducing in changing habitats.
Focus Question(s)
How do the frogs’ characteristics help them live in their habitat?
How are the frogs’ body structures alike and different?
Activity Guiding Questions
The class brainstorms ideas about which characteristics are important to study about the frog (i.e., size, color, shape, movement, body coverings, etc.). They must keep in mind that they will want to choose things that will allow them to make comparisons to the other two animals in this unit.
Discuss the importance of scientific drawings and the important elements that should be included in these types of drawings.
In pairs, students make specific observations of the frogs, focusing on specific body characteristics (see Teacher’s Guide for labeled drawing). They should be filling out Record Sheet 4-A (observations) and 4-B (specific drawing of their frog) during this observation.
As students finish both observation sheets they should discuss their findings with other students. Note: students should observe their own frogs as well as the frogs in other groups to best understand and meet the requirements of clarifying objective 4.L.1.4.

name the parts of the fiddler crab.
Integration Hints
The “My Habitat” activity (available at the end of Lesson 6 in the Teacher Guide) can be
assigned as homework or completed as part of a center rotation.
People often remark that crabs remind them of spiders. Students can research spiders and
compare them with fiddler crabs.
Science Notebook Helper
Recording Sheet 6-A can be easily created in a science notebook to record characteristics and
related observations. As students have had some practice recording observations of frogs,
expect more detailed observations from students. For example, instead of “The crab has two
claws,” you might guide students to record “The crabs have two claws. One claw is small, about
the size of a sunflower seed, while the other is much bigger. It looks like it is about two inches
long. The claws are white with brown spots.”

Lesson 9 – Observing the Behavior of the Frogs and Crabs (STC Animal Studies Lesson 7) Students observe and record how frogs and crabs interact with the living and nonliving elements of their habitats.
Clarifying Objectives
4.L.1.1 Give examples of changes in an organism’s environment that are beneficial to it and some that
are harmful.
4.L.1.2 Explain how animals meet their needs by using behaviors in response to information received
from the environment.
Focus Question(s)
How are fiddler crabs and frogs similar and different?
Activity Guiding Questions
Students continue to make observations and record information about the frogs’ and crabs’ behavior. They might also refer to observations and data collected about the animals in previous lessons.
After students complete their Science Discovery Activity, either during class or during centers, schedule a “Science Meeting” time where students can share their work. (Work on the Discovery Activity began in STC Animal Studies Lesson 4.) In the interest of time, you may want to have the students work in groups rather than individually. The class may also go back to their initial brainstorming sheets about frogs and crabs, adding new information and correcting information that was inaccurate. Note: Teachers have found it effective to vary to focus of the science meetings. For example, a meeting might focus on a single behavior among the three animals, an animal log checklist question, or several behaviors of one animal.
Students also complete a mid-unit self-assessment about their independent and group work.
Why might it be important to continue observing the behavior of the crabs and frogs?
What questions have you added to your lists?
How are the behaviors of the frogs and crabs similar? How are the behaviors different?

Students use their recorded characteristics to create poems about the crabs, frogs, or their
habitats. (See the Extensions section at the end of Lesson 7 in the teacher guide for some
examples.)
Offer sentence skeletons for students to make comparisons of the frogs and crabs: A fiddler crab
___, but a dwarf African frog ___. A frog ___, but a fiddler crab ___.
Students can research the life cycle of the frogs and crabs (and eventually the millipedes). This
would be a good connection to 2nd grade Essential Standards and Clarifying Objectives about
animal life cycles. (Second graders studied the life cycle of butterflies.) The teacher guide
provides blackline masters at the end of Lesson 7 to create life cycle wheels.

Lesson 10 – Living on Land: Millipedes (STC Animal Studies Lesson 8) Students create habitats and develop questions to help make observations of the millipede and its habitat. *Collect leaf litter (dry leaves, small twigs) to place in the habitat. Be sure to condition water in the spray bottles. Request students bring in leafy lettuce or mushrooms to feed millipedes.
Clarifying Objectives
4.L.1.1 Give examples of changes in an organism’s environment that are beneficial to it and some that
are harmful.
4.L.1.2 Explain how animals meet their needs by using behaviors in response to information received
from the environment.
Focus Question(s)
What are the characteristics of millipedes?
How can we build a good habitat for millipedes?
Activity Guiding Questions
Students will build the millipede habitats.
Have students compare their posters of habitats from the previous lesson with the habitats they built in class.
Finish the Venn diagram work started in STC Animal Studies Lesson 3 and continue the Habitat Information Table.
Students will learn more about the structure of the millipedes and complete their initial observations of millipede behavior.
Have a class discussion and question session about what the children have learned about the characteristics and habitat of a millipede.
What happened when you put food in the habitat?
Do the millipedes respond to food the same way as the fogs or crabs do?
In what ways is the millipede’s response different?
Science Content Words
Use these terms when teaching the lesson:
burrow to dig into the ground: millipedes often burrow into the soil or under leaves or logs to avoid bright light; tunnel or underground space: fiddler crabs often hide in a burrow for protection
Animal Studies Page 24
Integration Hints
Brainstorm with the class some phrases used to describe human behavior, but based on
behavior of other animals, such as “crazy as a loon” and “sly as a fox.” Have students invent new
expressions based on the behavior of the three animals.
Science Notebook Helper
Invite students to draw a millipede as a pre-assessment activity, similar to drawing a frog an
crab in earlier lessons. (Students observed millipedes in the Organisms unit in 1st grade.)
Students should create observation charts and record detailed observations.

Lesson 11 – Observing Millipedes More Closely (STC Animal Studies Lesson 9) Students observe, describe, and record observations of the millipedes’ body structure and behavior. *In addition to observing millipedes more closely, this lesson begins to get students thinking about the concept that living things rely on nonliving things (air, water, etc.) for survival.
Clarifying Objectives
4.L.1.1 Give examples of changes in an organism’s environment that are beneficial to it and some that
are harmful.
4.L.1.2 Explain how animals meet their needs by using behaviors in response to information received
from the environment.

advantage in surviving and reproducing in changing habitats.
Focus Question(s)
How are millipede similar and different?
How do the millipedes’ characteristics help them live in their habitat?
Activity Guiding Questions
Students will make more specific observations of the millipedes, focusing on specific body characteristics like they did for the frogs and the crabs. You may need to bring the millipedes out of their burrows for observation. Note: Students should observe their own millipedes as well as the millipedes in other groups to best understand and meet the requirements of clarifying objective 4.L.1.4. They should be filling out Record Sheet 9-A (observations) and 9-B (specific drawing of their millipede) during this observation. (Both record sheets are available at the end of Lesson 9 in the teacher guide; rather than copying record sheets, they can be easily reproduced in science notebooks.)
Continue the Venn diagram work from the previous lessons and add more information to the Habitat Information Table the class has been working on.
Have a class discussion and question session about the students’ observations and how these observations relate to what they know about a millipede’s characteristics and how these
Are there any nonliving elements of the animals’ habitats that affect their lives and that we should add to our lists?
Are there any important elements (such as light) missing from our lists?

Integration Hints
Students might research the life cycle of the millipede and create a life cycle wheel. Blackline
masters to create a life cycle wheel are available in the Extensions section at the end of Lesson 7
in the teacher guide.
Students might explore the behaviors of other nocturnal animals such as bats and owls. They
can present their findings to the class.
Science Notebook Helper
Students continue recording detailed observations.
Students may need to complete the triple Venn diagram on a separate sheet of paper that can
later be pasted or stapled into their science notebooks. Students will need to refer to previous
investigations for information, using their science notebooks as a reference tool/record of
learning.
Assessment Opportunities

Activity Guiding Questions
Students refer back to their “My Habitat” work from STC Animals Studies Lesson 6 and the School Habitat Web from STC Animal Studies Lesson 2. After discussing how these habitats meet their needs as an animal, students complete “My School Habitat” in their science notebooks.
This leads into a discussion about whether the home and school habitats are complete and whether the animal habitats the students have built are complete. Confirm the idea that humans are animals with habitats, too.
Have students create the observation chart (Record Sheet 11-B) in their notebooks. Then, take the students to an area in the school where they can observe their fellow humans (Some excellent locations include the cafeteria and the playground).
Finally, hold a brief science meeting where the needs of humans in their different habitats are discussed, and the last part of the Habitat Information Table is filled in.

How do the animals’ body structures help them survive in their habitats?
Activity Guiding Questions
Students discuss the body structure and function of the three study animals (fiddler crabs, dwarf African frogs, and millipedes) just as they did for humans in the previous lesson.
Students break into groups (the teacher guide suggests groups of ten, but science groups of four or five are also acceptable) and are assigned an animal.
“Did You Discover” sheets are distributed for the appropriate animal and students read about traits that are not easily observable in the classroom. Students then consult their science notebooks (including drawings and observation charts) to help them complete Record Sheet 14-A, 14-B, or 14-C, as appropriate for the group’s assigned animal.
Student groups then share their information about their animal with the class.
Have a class discussion and question session about the concepts discussed today.

Integration Hints
Have students research the ways humans change their behaviors to live in a variety of
environments on land, under the sea, and in space. Focus on the unusual places humans live and
ways they have needed to change to survive. Examples include explorers spending long periods
of time in Antarctica or astronauts in space.
Science Notebook Helper
This lesson provides an opportunity for students to use their science notebooks as a
reference/log of learning as they access information from earlier observations of animals. As the
unit draws to a close, students are challenged to synthesize information from various sources
(data charts/tables, scientific drawings, and observations) to explain how animals (including
humans) are fit for survival in particular habitats.
