Density Lab #1
We took two 250ml beakers and in the first beaker we put 20g of salt with 200ml of cold water and before we added the water its mass was 320.4g.
In the second beaker we put 200ml of warm water with no salt and it's mass was 303.9g.
The cold salty water had a density of 1.602.
The warm fresh water had a density of 1.5195.
The cold salty water was more dense than the warm fresh water.

Rainbow Salt Lab
In this lab we made colored layers of water by changing each layer's density. To change the density of the layer we dissolving different amounts of salt into it. To distinguish the different layers from each other we added food coloring to them.
