With Halloween just around the corner, bloody scenes are just a block away. Whether it is dripping vampire teeth, a bloody nose, or a leaky bandage, fake blood is sure to bring characters to life, so to speak.
While chocolate syrup might make convincing fake blood on black-and-white photography, it is not passable for real-life encounters or color film. In this activity, science helps you engineer your latest product: good-looking (and tasty!) fake blood.

Did you know that at sea level there are about 15 pounds of air pressing on each square inch of your body? This air is very helpful in our daily lives. For example, this layer of air helps to keep the Earth from getting inhospitably cold or hot. It can even help keep a bottle with holes in it leak-free! Try the activity to find out how.

If you've ever been shot with a rubber band then you know it has energy in it—enough energy to smack you in the arm and cause a sting! But have you ever wondered what the relationship is between a stretched rubber band at rest and the energy it holds? The energy the rubber band has stored is related to the distance the rubber band will fly after being released. So can you guess one way to test how much energy a stretched rubber band contains?

Have you ever wondered what would happen if two satellites crashed into each other in space? While space may seem empty, Earth’s orbit is actually crowded with satellites and debris. In this project, you’ll step into the role of a space engineer, using real satellite data to model orbits, track their movement, and predict potential collisions. You’ll explore how gravity and speed affect a satellite’s movement and learn how scientists use simple math and code to prevent…

Have you ever driven up a mountain, seen a sign reading "Hazard! Icy Roads Ahead," and wondered why ice makes roads dangerous to drive on? The answer has to do with friction—specifically, the lack of it.
Specifically, in the case of driving a car down the road, the friction that allows the car to move occurs between the tires and the road. This friction normally allows the car to "grip" the road—keeping the tires in contact with the relatively rough road…

You can probably find the center of simple shapes, like circles and squares, pretty easily. But, how do you find the "middle" of an irregular shape, like a drawing of a dog or a cat? This project will show you how to do it using nothing but string and paper clips!

Have you ever wished you could fly to space? Space flight is getting more accessible thanks to reusable rockets that make getting to space much cheaper. Civilian astronauts can even buy tickets for a few minutes in space! But exactly how high is "space"? How do engineers predict how high a rocket will go and figure out how to make it land safely? Find out in this project as you explore the physics of suborbital space flight.

Have you ever seen a mobile? Not a mobile phone, but a hanging art sculpture. You might have had such a mobile in your room when you were little. These mobiles hang from the ceiling and are usually made up of many layers of rods to which lots of differently shaped objects are attached with strings. When you look at the mobile sculpture, you might wonder how it can stay balanced all the time even when it is moving in the air. In this activity, you will make your own mobile sculpture and find out…
