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

This activity was designed for blind learners, but all types of learners can use it to organize an interactive model for learning the classification system (taxonomy) of living things.

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.

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

In this activity (p.7-8 of PDF), learners examine fossil formation.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.
