HOW TO MAKE IT!

CH 1NOTES #2

SCIENTIFIC METHOD

Scientific Method

- A series of steps used to solve a problem

STEPS:

1. STATE THE PROBLEM

EXAMPLES:• Why do leaves fall off in the fall?• What does a medicine do to the body?• Why does our eyes get goo in the corners in

the morning?• Does popcorn pop better when cold?

2. GATHER INFORMATION (research)

Read about what you want to learn about and research what people already know to help you come up with ideas or experiments; make observations about something you want to study

FOR POPCORN?

3. FORM A HYPOTHESIS – an educated guess * If …… then ……

A guess of what you think the answer to your question is after doing research.

Your hypothesis may be right, it may be wrong.

FOR POPCORN…?

WHAT WERE THE 1st 3 STEPS????

4. CONDUCT AN EXPERIMENT Need : - to get materials - to follow a procedure - to make observations - to collect data

Darwin spent nearly 20 years analyzingthe data he collected came up with his conclusions!

FOR POPCORN?

KEEP TRACK OF

OBSERVATIONS

DATADATAWhat data would you keep of during the experiment?

Experiment vocabulary

Control group – group not having anything changed

- used to compare

Experimental group – group that you made some change to

You wanted to find out if mice behave differently if you give them caffeine

• Experimental Group?

• Control Group?

1 2

1

Can have many experimental groups

http://www.youtube.com/watch?v=VhZyXmgIFAo

Should you just do one of each?

Constant – things that stay the same between the groups

FOR POPCORN? - same amount/ size bag of

popcorn - same time - same brand - same place in the microwave

ROOM TEMP

COLD TEMP

* you only want to change ONE thing at a time!!!

Variable – The things that change in an experiment

TWO TYPES:Independent variable – the thing that you changed

Dependent variable – what changed as a result at the end (usually something you can measure)

FOR POPCORN?

Independent variable? “1” thing “I” changed - the temp of the popcorn

Dependent variable? What measure at the end to know results

- the amount of kernels that pop

* should repeat the experiment over and over to make sure you keep getting the same results before

you make a conclusion

5. CONCLUSION - What you found out. Answer the problem in step one in a complete

sentence. Talk about the DATA you collected

WHAT WERE THE STEPS?

1. State the Problem2. Gather information3. Form a Hypothesis4. Conduct an Experiment5. Conclusion

BACK OF NOTES

• You have an example going over all of the steps to help you with any assignments.
