Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.

In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this design challenge activity, learners invent a convenient way for someone using crutches or a wheelchair to carry small personal items.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

In this outdoor game, learners role play populations linked in a food chain.

In this hands-on activity, learners track and record the passage of colored "pompom traits" through three generations of gingerbread people.

In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

In this activity, learners discover how their heart rate changes in different situations.

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

In this hands-on activity, learners discover the similarities and differences between a vertebrate and invertebrate by dissecting a perch and a crawfish.

In this activity, learners use geometry in observing the shapes and angles soap bubbles create when they join together.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.
