In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

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

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

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

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 are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners make scale models of the Sun and Earth out of paper mache.

This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

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

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

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

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

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

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.
