In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

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

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

In this activity, learners make balloon models of disease-causing bacteria.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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

In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

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, learners explore the relative sizes and distances of objects in the solar system.

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.
