No one can deny the devastating consequences of an oil spill on the local wildlife. Oil affects all levels of the ecosystem, from plants to fish and birds. What happens to water plants if you add motor oil to their pot? What is the effect of motor oil on the health of a goldfish, or water insects? What happens to the barbs of a bird feather if they are dipped in oil? Can you test different types of environmentally-friendly detergents for cleaning the bird feathers? Can you test different…

Have you ever watched an inexperienced video game player pick up a controller and start playing a game? Often the player bumbles around trying to figure out which button makes the onscreen character jump, run, turn left, or perform other actions. Some games are different though, they have control schemes that are more real-world based. For example, most modern Mario Kart games give you the option of steering with a joystick or turning the entire controller like a steering wheel, which is more…

Have you ever spent time spinning a hula hoop around your waist or arm? Could you easily do it, or was it difficult? Have you ever wondered how hula hoops work, or, in other words, what makes them be able to spin around a person's waist or arm? It comes down to the physics that is involved. Physics can help you determine what makes one hula hoop a winner and another a flop. In this activity you will get to create your own hula hoops and investigate how their masses affect how they spin. …

In this small group activity, students will build a plant seed (burr) from a Styrofoam® ball and other crafts materials. The seed needs to be designed in a way that it can be dispersed by attaching to a mockup animal (wool glove). Students will first test if their seed attaches to the wool glove and then carry their attached seed along an obstacle course inside the classroom. As students design their plant seed and mimic its dispersal via an animal, they will realize how some plants grow…

When you were little, did you ever make "music" in your kitchen by banging kitchen utensils on pots and pans? What if you could actually take those kitchen implements now, and play them with different sound effects? In this project, you can convert basic kitchen utensils into your own electronic drum set using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like.
IMPORTANT: The instructions for this project were originally written using Scratch 2 on a…

Almost all of the games we play are based on math in some way or another. Card games, board games, and computer games are designed using statistics, probabilities, and algorithms. Begin by reading about games and game theory. Then you can choose your favorite game and investigate the mathematical principles behind how it works. Can combinatorial game theory help you to win two-player games of perfect knowledge such as go, chess, or checkers? (Weisstein, 2006; Watkins, 2004) In a multi-player…
