The learner will ask yes-no questions to identify a secret shape (similar to Twenty Questions). Build understanding of shapes and logic skills with this game for all ages.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

In this activity, learners will conduct an open-ended survey, and then organize and analyze results. What languages does everyone speak? What’s the most common? the least common?

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

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.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

Put math of measurement into lining up — and make waiting in line fun. Choose a size characteristic that learners can physically compare, such as foot length or hair length.

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

In this activity, learners will keep track of how much they can do in one minute. Instructors can pick something everyone will do for a minute, such as jumping up and down or drawing stars.
