How many drops on a coin?

On Day 3’s, the first graders come to science in the morning in small groups. This allows me more time to work with the students and have activities that better suit small groups. This rotation the first graders worked on their predicting and counting skills. In this activity students were asked to guess how many drops of water they think would fit on each coin, penny, nickel, dime and quarter. After, each student counted as they drop water on the coin. They tallied and compared the water drop counts for each coin. They were very excited to see the differences among each others results and between each coin.
