Floating and Sinking (Room 8)

Today at SCIENCE we did an experiment about floating and sinking!

We needed water , salt and 3 different containers.  

Container 0    Container 1  Container 2

We had to fill each container almost to the top with water.

  Container 0 we left as water only.

Container 1 we added 1 tbsp of salt.

Container 2 we added 2 tbsp of salt.

 Then we added some different objects to see which mixture helped them to float.

That was lots of fun...of course the container with the most salt was the most buoyant.  WE ALL GUESSED THAT BECAUSE WE ARE SMART!
