Summer Science

Summertime always brings about boredom for Ella...especially when the temperature reaches 120 and it is too hot to go outside. Today happens to be one of those days.








Today Ella tried a science experiment about surface area...which she does not understand, so she thinks it is just about how many drops of water fit on a coin. The teacher in me had her create a question and hypothesis before starting her experiment.



Question: Which coin will hold the most water?


Hypothesis: I think the nickle will hold the most. (She told me it was because it is the thickest of the coins)



Experiment time:







Results: The nickle held 15 drops. # more than the penny and quarter and 9 more than the dime. (She was super excited that her hypothesis was correct)


Ella was not satisfied with just one experiment, so she found the turkey baster and tried the experiment again.


Hypothesis: She thought that the quarter would hold more this time because it was bigger.


This time it was a bit harder because the water was coming out on its own.







Results: The quarter held 7 drops and the rest only held 3.


Both of her hypothesis was correct!
