In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.

In this activity (pages 7-16), learners model various crystal structures with LEGOs. This activity also contains additional links that explain how to create other crystal structures.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

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

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 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 engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

This activity introduces learners to the structure and properties of carbon nanotubes.
