Do you have a favorite M&Ms or Skittle candy color? Have you ever wondered what dyes are used to make that particular color? Some candies are the color they are because of a single food coloring, while others may use a couple different dyes to create just the right appearance. In this activity you’ll get to do some scientific detective work at home to investigate which colored M&M’s candies use which dyes. If you have some M&M’s leftover… Read more

Have you ever seen news coverage or other pictures of an oil spill in the ocean and wondered how all of that oil could be cleaned up? Oil spills can devastate wildlife by covering them with oil, and they can damage our precious water resources by contaminating them with oil. Part of the problem of managing oil spills is that the oil can be challenging to clean up. In this science activity, you can test the absorptivity of different materials (called sorbents) to discover which ones are best at… Read more

Space Radiation Protection

Science Fair Project Idea

Engineering Design Process

The radiation sources recommended in this experiment are low-dose radioactive sources and do not require a license to purchase; they are safe to work with as long as these common-sense safety tips are followed: Wear disposable gloves when handling any radioactive source. Never rub your eyes or mouth while you are handling the radioactive source. NEVER swallow any radioactive source and use protective glasses when bringing a source within a few inches of… Read more

You use it basically every day and cannot survive without it—no it is not your cell phone, but water! It is one of the most essential compounds of the world and has become an increasingly important issue everywhere. You probably have heard that in many places droughts or water pollution limits clean drinking water supplies, and those supplies keep shrinking. When considering this, have you ever wondered why we do not just make our own water, and what water is actually made of? In this… Read more

Spread the Soap, Not the Germs

Science Fair Project Idea

Scientific Method

Do you wash your hands? You should— it's the best way to prevent the spread of germs. But germs can be tricky; they find nooks and crannies to hide in, so it takes good hand-washing technique to get rid of them. In this science project, you'll investigate which parts of the hand are the most difficult to wash germs off of. Read more

Have you ever wondered weather the outcome of a certain activity is predictable? For example, if you’re randomly picking a chocolate out of a box of mixed chocolates, can you predict how likely it is that you’d end up with a specific type of chocolate, such as a caramel-filled chocolate? To investigate this tasty topic, in this activity you’ll determine the frequency of different colored M&M’s in a package of M&M candies. M&M’s are… Read more

Study the Effect of Fertilizers on Algal Growth

Science Fair Project Idea

Scientific Method

You might not know it, but a lake without algae would be a very dull place. If there were no algae, there would be no small animals feeding on the algae, and there wouldn't be any fish eating the small animals that eat the algae. You might conclude that since some algae is good, more algae is even better, but algae growth has a down side. If there is too much algae, they can deplete the oxygen in the water, killing off other species in the water. What is one culprit that leads to algal growth?… Read more
