1) The scientific method involves observing a problem, asking a question, making a hypothesis, experimenting, and drawing a conclusion. 2) A 2nd grade class wants to cook two shapes of pasta but doesn't know how long each will take. 3) They will use the scientific method by observing the two shapes, questioning which will cook faster, hypothesizing the smaller animal shape will be quicker, testing it in an experiment, and concluding their hypothesis was correct.

1. SCIENTIFIC METHOD
The steps scientists follow to make tests

2. THE SCIENTIFIC METHOD
The steps scientists follow to make tests
1) Observe
2) Ask questions
3) Research
(gather information)
4) Make a Hypothesis
(guess)
5) Make an Experiment
6) Conclusion

3. A PASTA PROBLEM
 Grade 2 wants to cook some pasta, but there are 2
shapes and they don’t know how much cooking time
will it take .
 How will they think as scientists to solve this
problem ?

4. (1) OBSERVE
 What you see.
 Example:
I see 2 different shapes of pasta.

5. (2) ASK A QUESTION
 What you want to know.
 Example:
which shape will be cooked faster ????

6. (3) GATHER INFORMATION
 search for information to find my answer .
 Example:
•Small pasta is cooked faster than large pasta. k

7. 4) HYPOTHESIS (GUESS)
I think that the animal pasta
will be cooked faster
because it’s smaller.

8. 5) EXPERIMENT
Let’s make an experiment to
see if our hypothesis was
right or wrong !

9. LET’S COOK THEM IN THE LAB AND SEE
Pasta shape spiral shape animal shape
Time taken to be
cooked. 14 minutes 10 minutes

10. (6) CONCLUSION
 The answer to the question
 Example:
Yes !! Your hypothesis was right, the animal
pasta was cooked faster !
