In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

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

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.
