Straws and pipe cleaners are terrific materials for building models of pyramids and cubes.

In this activity, learners will explore the insect life cycle by making a model.

This demonstration activity models how Venus appears from Earth.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

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 two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners will explore what a constellation is and make their own.

In this activity, learners will discover how our universe is continuously expanding.

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

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

In this activity, learners will create their very own constellation.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

In this activity, learners will explore how light can refract or break apart into different colors.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.
