In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

In this activity (1st on the page), learners keep a "SLOG" or Sleep Log to study their sleep patterns.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

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 chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.

In this simple game, learners start to understand how to sort and categorize objects by trying to guess the connection between three items that someone else has chosen.

This lesson focuses on graphene and its electrical properties and applications.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In ancient Chaco Canyon, the people used a "sun dagger" petroglyph to mark the passing of seasons.

In this activity, learners will discover how fossils are dug out of the earth by carefully exposing treasures hidden in an artificial rock that is easily made at home.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.

In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
