In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

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

In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.

Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.

To convey the concept of how animals adapt to survive, this game asks learners to imagine what adaptations a given animal would need to live in a certain environment—including environments where such

In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity, learners explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

During this interactive "survival" game, students learn about the importance of camouflage and how it helps animals to blend into their surroundings, as either predator or prey.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.
