Introduction
Finding Order Atomic Structure, Energy, Moles
Unit Framework Annotation
This unit can be a starting place for the study of high school chemistry. Students will explore our
current understanding of the organization of matter, based on the accumulated body of knowledge
about the structure of the atom and the creation of elements through nuclear fusion. Properties ofmatter are introduced in relation to this organization. Students will explore the property of density,
which is highlighted in this unit because it is a property that students can easily investigate and about
which students harbor misconceptions.
Lab skills and measurement techniques are reviewed and/or introduced through exploring the
property of density. Students will research how scientific discoveries have led to the development of
our current understanding of the atom.
In keeping with research on best practice, the word, finding, is used purposefully in the unit title to
indicate that lessons in the unit incorporate inquiry and exploration.
The GPS elements addressed in this unit will be referred to or revisited in other units of this course.
With few exceptions, all elements of the Characteristics of Science Standards are integrated into thisunit.
The activities and tasks are suggested but should be adjusted, omitted or enhanced as needed for
specific class situations. Some classes may need more time, practice, or instruction for someconcepts. Others may need less. For these reasons, the number of days required may need
adjustment.
Note on safety: Review and require students to follow all appropriate lab safety rules,including the wearing of goggles and aprons, clothing safety and the safe handling of
chemicals. Students must be thoroughly knowledgeable about the use of safety equipment
including the shower, eyewash, sinks, and fire extinguisher.

data.e. Testing, revising, and occasionally rejecting new and old theories never ends.
SCSh8. Students will understand important features of the process of scientific inquiry.
Students will apply the following to inquiry learning practices:
b. Scientific researchers are expected to critically assess the quality of data including possible
sources of bias in their investigations hypotheses, observations, data analyses,and interpretations.
d. The merit of a new theory is judged by how well scientific data are explained by the new theory.
e. The ultimate goal of science is to develop an understanding of the natural universe which is free of
biases.
Complementary StandardsSC3b. Use the orbital configuration of neutral atoms to explain its effect on the atoms chemicalproperties.

Understanding and GoalsUnit Understandings, Themes, and Concepts
Order can be found in atomic structure. Changes in this order, are the result of energy changes inthe system.
Matter is composed of a limited number of elements created through nuclear events in theuniverse involving tremendous amounts of energy. Modern atomic theory of the structure and behavior of atoms rests on the combined work of
many scientists.
Properties, which are a result of structure, can be used to identify matter and predict its behavior. The fundamental unit for measuring amount of substance is the mole.Essential Questions
Why does the Earth have Uranium? (Where did the elements come from?) How has our current understanding of the atom developed over time? How does our current understanding of the atomic theory explain the characteristics of atoms? How do chemists deal with the small masses and huge numbers of atoms and molecules? How is the property of density determined? How can a physical property be used to identify a substance?

Unit Performance Task
Royal Society of Chemists
Teacher Note: It is fitting to teach atomic theory in the context of its history which adds interest to
the story. However, be careful to keep the focus of this task on the growing body of scientificknowledge, and how this illustrates the nature of scientific inquiry. While an understanding of the
relative order and time span of discoveries is relevant, guard against emphasis on dates.Constructed responses should be favored over selected response items in assessing this task.
Introduce this activity by telling the class about the Royal Society, which is the oldest scientificsociety in the world and is headquartered in London. Explain that the class will create their own
Royal Society Meeting. For this meeting, time travel will not be a problem. Everyone from
Democritus to modern day scientists will attend. It is customary at the beginning of the Society
meeting to elect a moderator. Being voted moderator is a high honor. The scientists must campaignfor this honor.
Students will work in groups (3 or 4) to develop a campaign to have a particular person who hasmade contributions to atomic theory elected to serve as moderator of the Royal Society of Chemists.
Examples of persons to include: Democritus, Dalton, Rutherford, Thomson, Chadwick, Bohr,
Heisenberg, Schrdinger, Seaborg.
Goals: to use information acquired in this unit to promote and clarify the importance of this persons
contributions to atomic theory; to gain a deeper understanding of the major discoveries involved inour understanding of atomic theory; to participate in a scenario of contributing and accumulating
ideas; and to understand the nature of science as a growing body of knowledge.Role: Each person will assume a role such as 1) the candidate 2) campaign manager 3) publicrelations (PR) person 4) media production manager
Audience: Other chemists and their constituents.
Situation: The Royal Society is going to convene. The meeting needs a moderator to preside over
the convened group. The first act of the Society meeting must be to elect this moderator.
Product 1: Each chemist and his/her team must campaign to be moderator. The campaign should
include a speech of introduction made by someone other than the chemist (1-2 minutes long)*, the
chemists campaign speech (3-4 minutes long)*, a PR campaign coordinated by the PR person andthe media production manager. It might include commercials, posters, placards, bumper stickers --
use your imagination- to explain the contributions or discoveries of this person. These artifacts
should be displayed throughout the classroom or other appropriate space.
*The combined speeches should not exceed five minutes, excluding applause from the audience.
Product 2: Hold the election. Students vote by secret ballot, with the teacher voting to break any ties.
Once the votes are tallied, the chemists will convene for a panel discussion on atomic structure with

the newly elected moderator presiding. The other members of each team will become the audience.Each student should prepare a list of five questions. The moderator calls on each student to ask at
least one question. The scientist panel answers and discusses the questions. Teacher assesses students
on the relevance and insight of their questions and the scientists on the correctness and insight oftheir answers.
Product 3: During the debate all spectators and scientists will take notes. Using these notes and all
prior knowledge, each spectator and each chemist will write a one page essay to express theirunderstanding of how our knowledge of the atom has progressed.
Rubric for Performance TaskNot included; rubrics should be designed by the teacher and based on the elements of GPS SC3.
PERFORMANCE TASKS AND LEARNING TASKS
Density of water performance task for learning:
Exploratory Phase: This task begins as an exploratory event. Give student pairs a graduated
cylinder, balance, and graph paper, with the instruction to determine the density of water. Be surethat students know and follow appropriate safety practices, but allow students to try out their ideas
about finding density. Do not mandate an exact procedure this time. During the exploration phase,
monitor for misconceptions. (A common misconception is that density varies with volume.) Afterthis preliminary exploration phase, facilitate student discussion of what they knew how to do and
what they were unsure of. Demonstrate and discuss density.
Teacher note: This task can serve as a pre-assessment. (It is possible that some chemistry students
have not had the physical science course.)
Investigation Phase: In this portion of the task, students measure density and deal with datacollected using two different procedures. Students will analyze the impact of choice of instrument on
precision and accuracy and use their density data to identify substances.
Part A: Instruct students to obtain five samples of water, using a beaker. For each sample studentswill record the volume and mass, graph the data and calculate the density. (Volumes between 10 and
100 ml are appropriate).
Part B: The students will repeat this process using a graduated cylinder instead of a beaker. The
data should be appropriately organized and graphed.
Debriefing this activity should lead students to understand:
the constancy of the density of a pure substance under controlled conditions the concepts of precision and accuracy in measurement the use of significant figures to reflect the precision of instruments and the consideration of
significant figures in the construction of a graph.
the concept of percent error

Part C:After instruction on the physical property of density, give students a set of metallic element samples
that are similar in color and luster such as tin, aluminum, and zinc. The student will determine thedensity of each sample, and then using a standard reference, such as the CRC Manual, propose the
identity of the element.
Teacher note: Differentiate for students who need more challenge by asking them to determine the
density of copper-coated BBs and use a standard reference to predict the element(s) in the BBs.These BBs, which are available at sporting goods stores, are actually iron under the copper coating.
Another extending or enriching task is to have students determine and compare the density of
pennies minted prior to 1982 and pennies minted in 1982 or later. Based on this data, studentsdetermine which pennies have the lower copper content. (Pre-1982 pennies have the higher copper
content. The post-1982 pennies have only a very thin outer coating of copper.
GPS that are integrated into this task include SC1b; SCSh1a; SCSh2; SCSh3a,b,c,e,f; SCSh4,SCSh5a,b,c,d,e; SCSh6a,b,c; SCSh7a,b; SCSh8a,b.
Suggested use: This task can be interspersed with direct instruction for both formative and
summative assessment.
Density Gradient: Model the construction of a density gradient column. Provide students withseveral liquids of different densities, such as a concentrated Karo syrup, water, vegetable oil, alcohol,
and food coloring. Ask students to predict the gradient (order from least to most dense) and then
experiment to confirm or refute their prediction.
As a further exploration, have students predict the depth to which various small objects will sink andthen test the predictions. Objects could include small pieces of Styrofoam, wood, cork, aluminum,
etc.
All safety requirements must be observed.
Suggested use: Use as a learning task, or adapt to an activating strategy demonstration. To create the
activating strategy, have the various labeled, colored solutions on the demonstration counter. Askquestions to elicit responses about the density of the liquids and predictions of what would happen if
they are gently poured into a one liter graduated cylinder. Then complete the demonstration, with
discussion of the results. Have students write their interpretation in their notebooks, logs, or as a
summarizing activity at the end of class.SC1b, SCSh1a;SCSh2;SCSh3a,b,c,e,f;SCSh6a,c
How big is big and how small is small?

Your first job assignment is to test a new, inexpensive calculator to see if it is dependable by actually
using it to count to 1,000,000,000. It is capable of counting at the rate of 264 digits/minute. So you
go to work. Figure out whether you will be able to finish this task before you go lunch. Calculatehow long this task will take.
The students may arrive at an answer using a variety of mathematical skills. After they have
calculated that it would take over 30 years, debrief the math. Reinforce/teach/practice dimensional
analysis.
Teacher note: This portion of the task is a great activating strategy for the lesson.
Next, introduce the idea that there is a relationship between real mass and the atomic mass unit.
Introduce the mole concept. Then, ask the students to calculate how long it would take to count to6.02 X 1023. Next display 12 grams of carbon, pointing out that it contains 6.02 X 10 23 atoms of
carbon.Use this demonstration to develop the concept of relative mass and moles.
Teacher note: This task helps the student to develop an understanding of the immense number of
and the infinitesimally small mass of atoms. This is an opportunity to introduce or reinforce
dimensional analysis, scientific notation, and significant figures (and to identify students who need
more help in this skill).
Measure a Mole
Instruct students to bring a mole to class. Alternatively, supply a variety of pure substances for
students to use. Students must choose the substance, and either: a. mass a mole of the substance or
b. some fraction or multiple of the substance. The final step is to prove to the teacher how many
moles they have massed. A quick internet search for mole day will provide many interesting waysto make this lesson memorable.
The following task may be used in conjunction with measure a mole.
Mole Map
Students will rotate through a series of stations. At each station, students will use a balance to collectdata and then calculate the other necessary information to complete the map. At some stations, one
mole of a substance may be the sample. At other stations some fraction or multiple of the mole may
be given. Students will record their data on the mole map, which follows. The given mass, the molarmass, and calculate and
Teacher will monitor and facilitate. Assessment should be both observation and assessment of the
completed maps.
Teacher note: The task is presented in this unit in the context of moles of an element but this task
can also be used to map moles of a compound.

BlackBox, Simulation: The teacher will prepare a series of shoe boxes by attaching an object such asa small ball in a chosen location to the bottom of the box. Then construct a grid on the lid of the shoe
box. The students could do this or the teacher could do in the preparation phase. If the holes are pre-
punched, then the boxes can be used over and over. The student will probe the box with a skewerand map the shape and location of the object on graph paper.
To debrief this activity tie this learning task to how scientists use indirect methods of collecting data
and how this is important to our understanding of atomic structure. Explain how this activity isanalogous to Rutherfords gold foil experiment. Use illustrations or video of Rutherfords work.
Teacher note: This task is useful for helping to address misconceptions or nave
understandings about atomic structure and addresses the essential question, How has our
current understanding of the atom developed over time?

The overview of the task is that a timeline of the major contributions to the modern ato be spaced on a timeline that is proportional to real time. Although the standard focuses on our
current understanding, this task should reach back into the earliest hints of understanding with
Democritus and other Greeks, and move forward from there. The timeline should include appronames, and contributions and historical markers of the same era.
A wide range of formats are appropriate for explaining the scienti
by each scientist and representing the time frame of their work. Possible formats are strips of papertaped together or a roll of adding machine tape. (This format has the advantage of requiring lessdisplay space and it reinforces measurement, proportion and modeling of time.) If this format is
