Science Challenge -  Something will float if it is lighter than the object it pushes away!!!

Last week we looked at lots of objects around our classroom and investigated whether they would float or sink.

Picture
Teacher set us a challenge to make our marla into a shape that would float

Picture
The marla in this shape sank right to the bottom of the tank





Picture
We warmed up the marla in our hands and squeezed it to change the shape so that the weight was spread more evenly.

Next we decided to test this "boat" to see how much extra weight it could carry.





Picture
The "boat" carried four marbles altogther, when we added five it started to sink!!





We had lots of fun!!
