Egg-periments

Egg-periments in the 3's class

Do you think an egg will sink or float in water?  Some of us thought it would sink, and some thought it would float.  We learned that it sinks.....

 But......what if I add salt to the water? 

 The egg rose to the top of the water. We talked about how the salt changes the density of the water. The 3's class had fun saying density with me. :)

Next, I placed an egg in a cup of vinegar overnight. When we came in the next day, the shell was gone. I let everyone take turns feeling the shell-less egg. Pretty neat!
