Another ice experiment.
An opportunity to discuss freezing and melting
while experimenting and having fun.
What we used
Fairy cake tray
What we did
First we filled the tray with water.
Then I cut the pipe cleaners in quarters.
We bent the tips so that they would stand up
and then we put them in the water.
Next we left the tray in the freezer overnight.
Next day we took the tray to the park and pulled
out the little round ice boats at the water fountain.
We watched them float, getting smaller and smaller
as they slowly disappeared.
You could use little twigs instead of pipe cleaners
if you were going to float them down a river or in a pond.
I had to fish all of the pipe cleaners out of the fountain after
they melted so i will use sticks next time.
