Put the math of measurement, numbers, and everyday life into improvisational skits.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

In this activity, learners cut a shape into two equal sized pieces and use their knowledge of geometry and space to prove that the two parts are equal.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

Learners investigate how drag affects the falling rate of objects.

In this physics activity, learners explore how sound is created by vibrations.

In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi

In this activity, learners conduct a simple test to find their blind spot.

In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.

In this activity, learners control the (apparent) size of a hole with their brain.

In this activity, young learners will describe objects by their properties and sort by color, weight and texture. This activity uses household items and toys for materials.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

In this activity, learners will learn about a person they admire (famous, family or otherwise) or even themselves and create a life-sized silhouette.

In this activity (on pages 15-18 of PDF), learners make a life-size two-dimensional paper model of their own skeletons.

In this activity, learners create a straw oboe to explore sound and pitch.

In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

These three short activities challenge groups to fit objects through paper and index cards: "Slots" presents the challenge for one learner to figure out which objects fit through a hole cut by another
