In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

In this activity, young learners and their caregivers use non-standard tools, like M&Ms and paper clips, to measure things around their home.

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

This is a quick and simple demonstration about reflexes (second activity on the page).

In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.

Learners follow a three-step process to start their own rock collection.

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

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

In this activity, learners will rate the day, a book, or something else on a scale from -2 to 2. This activity works well for groups of all ages.

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!

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

These math posters have questions written on them, such as: How fast can a cheetah run? or How long can a giant tortoise live? Post these around the room or leave them out for children to explore.

This magic trick is based on how computers detect and correct data errors.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.
