analyze

Infer

Experiment:

chart

evidence

data

When you infer you use clues AND

what you already know to make a hypothesis.

A chart is a display that organizes data into columns and rows.

Evidence is data that a scientist uses to prove

that a hypothesis is right, or wrong.

How Can You Measure ...?

Data is the information you get when you perform an experiment .

Learning target:

I can identify the right tool to measure an object and use the appropriate unit of measure to

record the data.

Language target:

I can read the unit of measure and in writing, record the data.

Heart Rate in Beats Per Second

1. Pour water into a dish

2. Sprinkle pepper on the water

3. Make a hypothesis: How does dipping your finger into the water, effect the pepper?

4. If you cover your finger in dish soap, how will it affect the pepper?

5. If you cover your finger in hair gel, how will it affect the pepper?

.

After you observe and analyze, you make a final decision, or conclusion.

When you analyze, you study something

closely and carefully

6. hypothesis

A hypothesis is an idea or explanation that can be tested by an investigation

When you observe, you collect information

by using your five senses.

observation

WHY does an octopus

camoflage itself?

HOW does it change color?

What is your hypothesis?

Learning target:

I can identify and explain what scientists do.

hypothesis

model

Language target:

"Maybe that's

the answer..."

I can identify and explain what scientists do,

verbally and in writing.

A hypothesis is your idea of what will happen and why you think it will happen.

Models help us understand things that are too big, too small, or too dangerous to do or observe.

1. Identify the problem

2. Gather information

3. Create a Hypothesis

4. Do an Experiment

5. Analyze the data

6. Draw a conclusion

7. Re-test
