ScientistsGallery Walk.

• Lay your ISN on your desk, open to your drawing of a

scientist doing science.

• Don’t worry if you have not finished; you will be observing

others interpretation of a scientist not how others draw.

• You will have 5 min. to walk around visiting other ISNs.

• The following questions should guide your observations:

- What do you notice about the scientists in the drawings?

What do you wonder?

ScientistsThink-pair-share.

• Take a minute to jot down some answers to the following

questions in your ISN:

- What do all (or many) of our pictures have in common?

- What is missing from our drawings?

- Did anything surprise you?

- Did anything stand out to you?

• Discuss your answers with your neighbor (team if none). Even

# will start & have a minute, then odd # will have a minute.

Observations vs. Inferences

Scientific Method

HousekeepingGuest teacher on Thursday, 21 Sep.

Observation vs. InferenceObservations.

Any information collected with the senses.

The skill of describing scientific events.

Quantitative: measurable or countable.

• 3 meters

• 4 marbles

• 50 kilograms

Qualitative: described, not measured.

• Red flowers

• Smells like fresh baked cookies

Adapted from slide presentation @ link: https://docs.google.com/presentation/d/1PMbF-1iR6gs-iu3Eud1fWqM8YQS7PxIq19GA6VDuKKY/edit#slide=id.p6

Observation vs. InferenceInferences.

Conclusions or deductions based on observations.

The process of drawing a conclusion from given evidence.

Inference Activity:

• You will close your eyes & quietly listen to 3 observations.

• After the observation has been shared, you will open your

eyes & write your inferences in your ISN (right side).

• Do not share your inferences until asked to do so.


Observation vs. InferenceInference Activity:

Now close your eyes & listen to the observations.

• I hear people screaming.

• I smell cotton candy, popcorn, & hamburgers.

• I see a lot of people.

Now open your eyes & write down your inference, but do not

share it with anyone yet.


Observation vs. InferenceInference Activity:

What inferences about the observations did you make?

• Amusement Park

• Sporting Event

• Something else?


Observation vs. InferenceMystery Footprints.

You will be asked to view a series of 3 images.

Record 3 observations & 1 inference for each image.

Do not share your observations or inferences until asked to do

so.

Discussion Questions:

• What event happened to cause these tracks? What is your

hypothesis?

• How do your observations support your hypothesis?

• As a class, were there similarities/differences in our

observations? In our inferences?

• Why is it important not to share our observations & inferences

right away? Can your answers influence other?

• Can we know, with 100% certainty, how these footprints were

formed? Why/why not?


Scientific Method

Scientific MethodScientific Method:

• A series of steps to follow

when answering a question

or solving a problem.

• There are 6 steps.

Ask a question

Background research

Scientific MethodScientific Method.

Ask a question:

• Scientists ask questions based on observations from their

surroundings.

Background research:

• Conduct research to identify if the question has been asked &

studied by other scientists


Scientific Method.

Ask a question:

• Scientists ask questions based on

observations from their surroundings.

Scientific Method.

Form a hypothesis:

• Make an educated guess about

what you think your question.

Test your hypothesis:

• Set up an experiment to test

your question/hypothesis.


Form a hypothesis:

• Make an educated guess about what you think the answer is

to your question.

Test your hypothesis:


Scientific Method.

Analyze your results:

• Look at your results & decide what they tell you about your

question/hypothesis.

Form a conclusion:

• Decide what the answer to your question/hypothesis is &

ask:

- Was it proved or disproved?

- Do I need to do the experiment again to find out more?


Analyze your results:

• Look at your results & decide what they

tell you about your question/hypothesis.

Ask a

question:Why does that pattern

occur?

Background

research:Has someone else

done a similar

experiment?

Formulate

Hypothesis:What are the general

causes of the

phenomenon I am

wondering about?

Test

hypothesis:If my hypothesis is

correct, then I expect a,

b, c, …

Variables

Constants & Controls

HousekeepingGuest teacher on Thursday, 21 Sep.

VariablesVariables.

A quantity or condition that can change.

Can be continuous or they can be discrete:

• Continuous variables can have many values.

- E.g. time can have many values, plant growth, amount of

sunlight etc.

• Discrete variables are ones that have a few, distinct values.

- Something can be either on or off, present or absent, or a

person may have blue, brown, green or hazel eyes.

Adapted from Sciencing website @ link http://sciencing.com/independent-dependent-variables-science-kids-8026692.html

VariablesThere are 2 main types of variables:

• Independent/Manipulated Variable (IV)

- The variable that is changed by the scientist; the ‘I control’

variable.

- A good experiment has only one IV

• Dependent/Responding Variable (DV)

- The variable that might change because of what the

scientist changes; what is being measured.

- The value of the DV is caused by & depends on the value

of the IV.


VariablesYour hypothesis can TELL you what your variables are!

• E.g. If I drink Mountain Dew before bed, then I will not sleep

very much.

- IV: Drinking Mountain Dew

- DV: Amount of sleep


VariablesUse the hypothesis to identify the variables:

• If I leave all the lights on all day, then my electric bill will be

expensive

- IV: ____________________

- DV: ____________________

• If I brush my cat more, then there will be less fur on my

furniture

- IV: ____________________

- DV: ____________________


VariablesNow read the following experiment and identify the independent

and dependent variables.

• Elizabeth wanted to test if temperature affected how fast milk

goes bad & curdles. She left milk in a room temperature

closet, a fridge, & a oven that was turned on low heat. She

then measured how rotten the milk was after 10 days.

- IV: ____________________

- DV: ____________________


Constants & ControlsConstant:

• Something that a scientist makes sure is the same throughout

the experiment

• E.g. Watering plants the same amount of water or taking

measurements at the same time each day.

Control:

• The part of the experiment that the scientist doesn’t change or

add the variable to.

• E.g. The plant with the white light

Entry TaskHomer notices that his shower is covered in a strange green

slime. His friend Barney tells him that coconut juice will get rid

of the green slime. Homer decides to check this out by spraying

half of the shower with coconut juice. He sprays the other half

of the shower with water. After 3 days of "treatment" there is no

change in the appearance of the green slime on either side of

the shower.

Complete the following in your ISN (right):

• What was the initial observation?

• What is Control Group?

• What is Independent (Manipulated) Variable?

• What is the Dependent (Responding) Variable?

• What should Homer's conclusion be?

Graphing Data

HousekeepingBring your Biology textbook on Monday, 25 Sep.

POGILPOGIL review.

Trade papers with your neighbor.

GraphingGraphs?

Pictorial display of information.

Makes it possible to get a quick impression of a great deal of

data & easily make comparisons & draw conclusions.

Often used by governments, businesses, & education

Appear in reports, newspapers, & magazines.

GraphingGraphs.

Four main types of graphs:

• Pictographs

• Circle Graphs

• Bar Graphs

• Line Graphs

GraphingPictograph.

Uses pictures or symbols to display information.

Usually has a key showing the value of each symbol.

Read by counting the symbols on a line of a graph & computing

their value.

Circle Graph.

Uses parts of a circle

Shows values in each

is called a segment or

Segments of a circle

add up to a whole or to

100% of the topic.

GraphingCircle Graph.

Uses parts of a circle to show information.

Shows values in each part of a divided circle. A part of a circle

is called a segment or section.

GraphingBar Graph.

Uses thick bars to show information.

Drawn in either direction; running up

& down (horizontal axis) or left to

right (vertical axis).

A graph may have a break in the

vertical axis meaning that some

values have been left off to save

space.

GraphingLine Graph.

Drawn with one or more thin lines that

extend across the graph.

Drawn using values along a horizontal

& vertical axis.

Most useful in showing trend &

developments.
