Recently, my students were studying water properties. One of our activities included dropping water onto a coin. I like how inexpensive the activity is. Each group of three students used one coin, one dropper, and a towel to drop off the coin and table. Students switched who used the dropper so everyone had the opportunity to participate.
We used pennies in this activity to ensure every student had something similar to compare. Students first predicted how many drops they thought they could put onto the drop - they then allowed water to fall a drop at a time onto the coin. Students observe the coin after there is a water puddle on the top. It is interesting to hear student comments as they see the water acting as a magnifier.
Students are consistently surprised and try to "outdo" the results of their peers.
How might this activity be used to help students with math?
How could you adapt the activity to include Language Arts?
