Dissolving:

Today, in Science, Class 12 looked at objects and their solubility. We had to test whether certain objects would dissolve in water or not. Some of the materials that we tested were:

Protein Powder
Sugar
Salt
Flour
Chalk
Gravy Granules
Coffee Granules
 

After that, we were allowed to design our own experiments using the equipment we had. We were allowed to design a fair test with dependent variables and independent variables. It was entirely up to us to choose what we changed! We had to make predictions about our hypothesis and then write up our results.

Have a look at some of the snaps from our experiment!
