Learners will explore the chemistry of mucous and its importance to our health by following a process to make their own replica "snot." The activity includes a time and age recommendation, a materials

In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

In this activity, learners investigate the basic crystal structures that metal atoms form.

No glue is needed for learners of any age to become marshmallow architects or engineers.

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

Teams of learners use a series of stick figures made from pipe cleaners to model a dance routine. Then, they use this model to communicate to another learner who performs the dance routine.

In this engineering activity, young learners investigate multi-level buildings.

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.
