8Science Chemistry Unit

Big Ideas about chemistry:

In this unit, I sound that density had a lot to do with their physical properties. Density helps us find out about viscosity and use methods that rely on density to separate substances. For example, the separation funnel that releases lower density substances within mixtures.

Calculating the volume of an irregular object is pretty hard, but we learnt in class that we could put the object in water and measure the volume of water that it takes up.

Chemical and physical properties can sometimes be confusing. We did a bunch of interesting new experiments to judge whether they were physical or chemical, sometimes the results seemed physical, sometimes they seemed chemical.
