We would like to discover if Humpty Dumpty could float and if he preferred the pool (tap water) or the beach (salt water).
The children made their predictions before we began our experiment. Then, we filled two cups with water. We added our first Humpty Dumpty into plain tap water (pool).
We added salt to our second cup and dropped our second Humpty Dumpty into the salty water (beach).
We found that Humpty Dumpty does indeed float under the right conditions – in the salt water. I guess he’s a beach egg!
