In this activity, learners identify different classes of matter based on physical properties.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

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 inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

In this activity, learners explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit.

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

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

In this math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times.

In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.

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 make plaster casts of an animal track to learn more about animals and animal behavior.

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

In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

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 activity, learners explore healthy choices related to the foods they eat. The importance of a variety of fruits and vegetables to a healthy diet is the focus of the experience.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.
