Dec. 5

As promised, here are the results of our experiment!

If you remember, we made a hypothesis about how many drops we could fit on the surface of a penny. Most of us guessed anywhere 3 - 10.  But... we actually got between 16 and 34!  The students were amazed that so many drops could fit on such a small surface. Below shows a bit of the process of our experiment today:

We started by dropping water drop by drop:
  


As we did this, we took a tally of how many drops we added:



 We kept going until the tension became too much for the water.  We learned that depending how forceful we were could change our end result:
 

When we finished we made some observations and recorded what we learned:


 We have really been focusing on understanding the scientific vocabulary. We will continue to review these words through out the unit to ensure that students have a sold understanding of them.  This is a fun activity to try at home.  You could try with different coins to practice estimating as well :)
