In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

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, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

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

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

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.

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 activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

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

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates.

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.
