In this activity, learners investigate different types of bird beaks using household items which mimic different beak examples.

In this activity (10th activity on the page) about the sense of touch, learners make Braille letters out of cork or cardboard and map pins.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

In this activity, learners will explore how animal in cold areas stay warm.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

Use echolocation to find others and experience how whales’ senses have adapted to suit their environment. In pairs, learners are blindfolded and use containers filled with marbles to find each other.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this activity, learners will explore how different bird beaks work and discover what birds can eat based on their beak shape.

En esta actividad, los participantes explorarán las fuerzas de gravedad y la resistencia al aire usando paracaídas.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners make pretend snakes and use them to explore estimation and measurement. Learners roll out clay snakes and estimate and measure their lengths and diameters.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.
