This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.

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.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

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

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

In this activity, learners discover a brain process called habituation.

In this activity, learners overlap the three primary colors to see how all other colors are made.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

We're told from a young age that we have 5 senses, but we have many more. One of which is our awareness of our own body part's orientation and position.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.

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 (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this lab (Activity #1 on page), learners explore how we see color.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.
