Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

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

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

In this activity (11th activity on the page), learners use their sense of touch to identify matching pairs of objects hidden in bags. Learners can also play this game with partners.

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

This is an activity exploring color and color mixing.

Use this activity (13th activity on the page) to introduce learners to the sense of touch. Learners collect objects of varying textures like feathers, rocks, sand, etc.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.

In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.
