In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

This is a simple activity for learners to create a traditional musical instrument. Pan Pipes have developed all over the world in different cultures, from South America to Greece and China.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.

In this web-based activity, learners try to figure out who in an online chat room has their matching puzzle piece.

In this activity (on pages 20-23 of PDF), learners build a model of a power plant using simple materials.

In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

In this geology activity, learners use a microscope to discover and identify the components of sand.

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.
