Will it Float?

Yesterday our home learners group had a get together.  Our activity was an activity that I had done in high school physics.  The kids had a great time.

Modeling clay
Container that holds water

The Activity:

First we had/helped the kids make their boat. It was interesting for me to watch Thing 1 create his boat.  His first boat, had walls and he wanted a sail.  However, while I was helping him make a sail, he flattened his walls and turned his boat into an “island.”  The sail became a tree.

Once everyone had created a boat, we let the kids put the boats in the water.  Of course, some sank immediately and others held up great.  While they continued to play with the boats, we lead the kids in a discussion of why some boats floated and others didn’t.  What did boats need to have to keep the water out?

Then we expanded the activity a little.  We reformed some of the boats that were hit by Thing 2’s ball of clay.  Then had the kids take their hands completely out of the water and set all the boats that had floated into the water.  We then added pennies to each boat to see which one could hold the most pennies before sinking.

Once all the boats were sunk, my boys had a great time playing with the pennies and boats in the water.

The kids had a great time with a fun hands on activity.

Have you done a fun activity at a playgroup?

  8. As a random idea wouldn’t it be interesting to do this for baby Moses and see if you can let him float.
