In this laboratory exercise, you will choose one peanut from a bowlful and make "identifying observations" about the peanut. Then you will place the peanut back in the bowl and return later to try to find it again by using your observation skills.
Before you begin the investigation, you should reflect on the outcome. You have already learned how to write a good hypothesis. Try to identify which of the following would be a good hypothesis for this investigation.
I will identify the correct peanut.
If I make careful observations of a peanut, I will be able to identify the peanut at a later time.
Peanuts are so much alike that they cannot be separated by unique characteristics.
If you chose hypothesis 2, you are correct! Hypothesis 1 does not suggest any experimental design. Hypothesis 3 is not falsifiable. Although unlikely, it is possible that you could search through hundreds of identical peanuts and not be able to find one that is different in the sample. This doesn't mean there isn't a different one; it just means that you didn't find it.
Now, it's time to start the investigation!
