In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners discover the importance of maps and scale as they work together to create a map of the classroom.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this mathematics activity (page 4 of the PDF), learners will explore the relationship between the diameter and circumference of an object.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.
