State Problem• Your problem is what you are testing.

• Choose something that you are able to research and that interests you.

Page 3: How do we use the  Scientific Method?

State Problem Cont.• Always have an Independent and Dependent

variable.– Independent – What you are changing.– Dependent – What you are measuring.

• Your problem must be written as a Question– Ex: If I give one plant compost, it will grow taller

than the plants without compost.

Page 4: How do we use the  Scientific Method?

Gather Information• Perform any research necessary.

• Often times, you will find previous attempts at what you are experimenting on.

Page 5: How do we use the  Scientific Method?

Form A Hypothesis• Write “If...then” statements when

creating a hypothesis.–Ex: IF I water the plant every day, THEN

it will grow tall.• Must address both variables.

Hypothesis Cont.• What if I’m wrong?– It’s not about being wrong or right.– Educated Guess

Page 7: How do we use the  Scientific Method?

Perform An Experiment• This is how you test your hypothesis and

where your data will be collected.

• You should have at least ten trials.

• Mistakes happen – DO IT AGAIN!

Page 8: How do we use the  Scientific Method?

Analyze Data• 2 types of data–Quantitative – numbers–Qualitative – descriptions

• You must write down daily what you observe and measure.

• Data is your PROOF!

Draw Conclusions• Conclusions tell you if your hypothesis was

“SUPPORTED” or “NOT SUPPORTED”

• Supported experiment is repeated to to collect more data.

• NOT Supported hypothesis is revised and the process begins again.
