This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

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

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 (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 learn about proprioception, or the body's sense of its place and position in space.

In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

In this activity (14th activity on the page) about the sense of touch, learners examine if it is easier or harder to identify an object if they move their hands over it.

Known as the waterfall effect, this activity demonstrates adaptation in our visual system.

We don't normally view people upside down and so our brains aren't accustomed to it.

In this online activity exploring our perception of "cuteness," learners adjust various factors (like pupil size or length of limbs) on a face, a cat, and a hammer.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.

Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!

This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.

This activity is designed to let learners measure their reaction time or response time to something they see.

Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.
