In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

This activity (page 3 of the PDF under SciGirls Activity: Dinosaurs) is a full inquiry investigation into fossil hunting and identification.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

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

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

Many people get water from a source deep underground, called groundwater.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

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 environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.
