We studied why thing of the same mass and density float or sink (Full pop cans). I think that the diet Coke floats because it was set in gently and didn’t break the surface tention but the Mt. Dew sank because it was just dropped in and had enough force to break the surface tention of the water then can’t float up.
Lesson 1: Matter, Matters
1. What is Chemistry?
The study of matter and how it changes.
2. What is Matter?
Anything that has mass and volume
solubility – how well something dissolves in water

What is the formula for Density?
Density = mass/volume
Density Lab Blog Post:
1. Explain what you did in the density lab and explain why the property of density determines whether an object will sink or float. Also explain how can an two objects of the same size have different densities.
What are the building blocks of matter?
Atoms
Build a model of an atom including it’s parts and orbits.
