In this investigation, learners gather information on various food items during a field trip to a local grocery store.

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 identify different classes of matter based on physical properties.

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.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

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

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

Learners measure irregularly shaped bones using a variety of measurement methods and tools. Then, they measure again using standard conventions and metric tape measures.

In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.

This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

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.

Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land

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 chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.

In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

In this activity, learners investigate how geometry plays a role in perspective.

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 outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys
