Inquiry based activity for Junior/Senior infants.
I would introduce the lesson by having the children come in from yard to find teachers bottle of water knocked over and a puddle of water left in the middle of the classroom. I would then ask the children how are we going to clean this water up? In their groups they will come up with different materials we can use from around the classroom. Each group will then choose 4 different materials and using a worksheet will list them from 1-4 with 1 being the material they think will clean up the water best. Each group will chose one leader to try out a different material. After all materials are used the children can draw a picture of the material that worked best on the bottom of the worksheet to reflect on the experiment. As a follow up, a few days later I will do the same water bottle incident to see if the children will remember which material worked best last time to clean up the water.
