In this activity, early learners simulate fossil prints in play dough or clay.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity/demonstration, learners explore pollen and how insects and animals transport pollen. Learners investigate and compare wind and animal pollination.

In this activity, groups of four learners must complete a set of four manual tasks. The restrictions are that they must complete the tasks in a limited time while wearing garden or rubber gloves.

Learners participate in a variety of activities modeling different disabilities.

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat

In this activity, learners explore the work of paleontologists.

In this activity, learners explore dinosaur fossils by making cast models of a T. rex. First, learners read about and research how dinosaur fossils form.

In this activity related to dinosaurs, learners explore why animals live in families. Learners discuss and identify animals living in families or groups from images and photos.

To discover the risk and protective factors involved in substance addiction, learners play a game of chance to determine whether a fictitious child is likely or unlikely to abuse drugs.

In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this activity, learners play a game to simulate the food chain.

In this activity, learners investigate the history and development of agricultural biotechnology.

Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.
