Can gelatin (like Jell-O ®) change the speed of light?

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

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 (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

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 math activity, learners play a game and try to be the first player to identify their partner's rule. Learners identify the rule by finding commonalities between three familiar objects.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this art/science/math activity, young learners are introduced to the concept of symmetry in nature.

In this activity, learners use geometry in observing the shapes and angles soap bubbles create when they join together.

In this activity, learners use their hands as tools for indirect measurement.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this activity, learners cutout a set of shape finder templates to explore shapes in the world around them.

Spin a short piece of PVC pipe that's been marked up, and watch a triangle appear. Enjoy this optical illusion from the Exploratorium's Science Snack series.

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.
