This is usually (not always) the first step in scientific inquiry.

A question about an observation.

1. Posing a Question!

Multiple Choice

Usually a question scientists asked is based on...

• an observation

• an answer

• another person's work

This is a testable idea! (If I give the suggested amount of water to a plant, it will be healthier.)

Hypotheses should be an "If.. then..." statement that includes both the independent variable and the dependent variable!

Develop a Hypothesis!

Identify the independent and dependent variable in this hypothesis: If I tie my shoes in double knots, they will come untied less often.

dependent variable

This is an experiment where only 1 variable is changed on purpose!

Design a Controlled Experiment!

Multiple Choice

How many variables does a controlled experiment have?

• Just 1

• As many as you can count.

• 3 is always best.

• What's a variable?

This is when you organize your data into charts and graphs!

​Summary of what you have learned!

Hypothesis could be reevaluated!

​​Draw Conclusions

Repeat your experiment!
Share it with others to have them replicate your findings!

​​Communicate!

Multiple Choice

Why would it be good to communicate your findings?

• The best science is repeatable and replicable. This means that it can be verified.

• Keeping it to yourself is a better way of doing science. This ensures that people wont steal your ideas!

• The best things are always kept secret. If you share it must not be true.

Never a guess!
Best known fact of the time!
Explains phenomena most thoroughly!
Explanation!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Scientific Theory

Describes something we can witness in nature and holds true anywhere that it is observed!

Organize into the correct category:

Mr. Jones wants to test the effect different sports drinks have on athletic performance during a running event. He uses Gatorade, Powerade, and Prime. Place each part into the correct category!

height of the plant

same music

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. Label each variable/group properly.

Dependent Variable

Multiple Choice

What is the difference between a scientific theory and a scientific law?

• A theory is a guess, while a law is a proven fact

• A theory explains phenomena, while a law describes patterns

• A theory is less reliable than a law

• A law is a hypothesis that has been tested
