In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

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

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

In this activity, learners explore the different heating properties of soil and water.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
