Space Sand truly is the closest thing to soil from Mars that most of us will ever experience. Reddish in color and very dry and dusty, Space Sand is hydrophobic sand with the same properties as sand on Mars. And it never gets wet—put it in water and take it back out, Space Sand stays completely dry. Space Sand comes with information about its properties and suggestions of tons of fun experiments to do. Use it to make underwater sand sculptures, clean up oil, improve plant growth, and much, much more. Space Sand is currently being used in NASA Mars Exploration Classroom Experiments. This kit comes complete with 35 grams each of black, red, and white Space Sand.
Atoms and Bonding
Atoms are composed of protons, neutrons, and electrons. Two or more atoms bond together to create a molecule by sharing electrons. If the electrons are distributed evenly throughout the molecule, it creates a non-polar molecule. If the protons and electrons are not evenly distributed, this makes the molecule polar. Like a magnet, the molecule has a side that is more positively charged (with more protons) and a part that is more negatively charged (with more electrons). Polar molecules tend to bond only with other polar molecules, and non-polar molecules bond with other non-polar molecules. For example, water is a polar molecule, and oil is non-polar. Therefore, oil and water do not mix. Anything that dissolves or gets wet in water is polar, and anything that does not is non-polar. Likewise, anything that dissolves or gets wet in oil is non-polar.
Space Sand is regular sand treated with silicon vapors. This gives it non-polar properties, so it never gets wet in water.
Carbon Dioxide (CO2) is a non-polar molecule
Water (H2O) is a polar molecule
