In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

In this activity, learners create their own weather forecast map.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.

In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

In this activity about flight, learners explore how high they can jump. Learners dip their finger in ink or dirt, then jump as high as they can and mark paper attached to the wall.
