This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

During this lesson, learners will determine their blood pressure and learn about systolic and diastolic pressures.

In this activity about neuron/target muscle recognition (page 44 of the PDF), learners arranged in two rows facing away from each other use string to simulate neural development.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

What keeps bubbles and other things, like airplanes, floating or flying in the air?

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

In this activity learners will explore the concepts of density and matter in their quest to answer one simple question-will it sink or will it float?

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.
