Today we did a science experiment relating to our topic “The Seaside”.
First, we put a fresh egg into a jug of water and we watched as the egg sank to the bottom of the jug.
Next, we added four tablespoons of salt to the water and discussed what would happen when we put the egg into the water. We were amazed to see that the egg floated in the salty water.
Here are some of our ideas:
“The egg floats in salty water because the water is thicker because we put salt in that is why boats float”.
“Can we try if a Numicon number four shape will float? I think it will because it is made out of plastic and plastic is light. Yes, you see it floats".
Maybe you could try the experiment at home!
