In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this activity, learners discover that our hands are not reliable thermometers.

This activity (on pages 19-25) is about fleas and ticks, which are common pet parasites.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

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 examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

In this activity, learners will explore how the human brain interprets environmental stimuli.

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.

In this neuroscience activity (5th activity on the page), learners explore their sense of touch without using their senses of vision and hearing.

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.

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