Buoy, Oh Buoy!

Mama said that for our next experiment we needed a raw egg!

We were all worried that we would have to handle the raw egg. I didn't want it to break and get everything all messy.

Mama poured fresh water into a big glass and then added the egg. The egg went to the bottom of the glass!

Next, Mama took out the egg and added a lot of salt. She put the egg back in and it floated right to the top. It was silly.

Mama then poured out half of the salt water and slowly added some fresh water back into the glass. When she put the egg back into the glass, it sank and then raised back up to the middle.

It was fun to learn about buoyancy without having to get all messy from a raw egg!

A Short Meeting

Mama gave us each a spoon and a plastic cup. Then she had us dump some salt into the cup. Next she had us add black pepper. We had to stir up the salt and black pepper with the spoon to mix it up.

Mama added water and asked us to stir it all together but not make a mess.

After we were done, she asked us, "Where did all the salt go?"

I looked in my cup and couldn't find the salt!

Mama explained to us that the salt dissolved in the water.

We asked why the black pepper didn't dissolve and Mama told us it can't dissolve in water.

I had a lot of fun.
