In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

In this activity, use standard playing cards to introduce learners to cellular interactions such as cell to cell recognition and signal and receptor specificity.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

In this activity, learners will observe and record living things with in outlined outside space.

Learners turn over a random selection of cards from a larger set. From the words revealed, they try to determine the sentence represented on the larger set of cards.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.

In this math lesson, learners apply measurement skills to determine, in dollar bills, the capacity of a suitcase.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.
