Density
Mixing of different densities
I experimented with different liquids and used basic density equations to calculate their densities (mass/volume) and predict which liquids would float on top of each other. I then proceeded to actually take these liquids and suspend them on top of each other to test if my predictions were correct.
The project was very fun. I performed it in the 5th grade and since them have found that in basic chemistry once will encounter the concept of density and over and over again. I think this is a project every student should have a chance to do because it was not only fun but it also taught me a lot about science.
Barry's Response - A good idea, appropriate for the grade level.
