Basic Properties of Matter



Using only water, oil, food coloring, 2 clear glasses, and a fork, you can create "fireworks" right in a class of water. Utilizing the property of density, drops of food coloring will slowly fall through oil, appearing as fireworks do after they have been launched.

As it turns out, hot and cold water actually don't have the same densities! Learn why in this experiment using two glasses, hot and cold water, food coloring, and a heat safe pan.

Observe the property of density using your favorite Halloween candy! With water, a mug, 5 cups, a tablespoon, a straw, a clear glass or bowl, and skittles you can create your very own rainbow in water all thanks to density.

Wonder why it feels so much easier to float when you're swimming in the ocean compared to in a pool? You can thank salt and density for that. Explore this property using water, salt, baking soda, sugar, cups, and a couple of eggs!


Basics of Matter

Atoms and matter are the building blocks of science. They are involved in every aspect of science, so it is important to understand their basic properties.

  • Use this simulation to understand the basic structure of an atom. Utilize the game provided to test your knowledge!

  • Use this simulation to put together atoms and understand molecular structure!

  • Learn about changes in energy and heat with this simulation.


Density is the measure of mass per unit volume, usually grams/cm^3, and measures the degree of compactness of a substance.

  • Play around with different materials and fluids to better understand density: Density Simulation

  • If you want to understand the concept a little bit better, here's a good overview of density that may help.
