In this hands-on botany activity, learners sprout vegetables in film canisters. Learners grow nine seeds each of cabbage, radish, and parsley, experimenting with changing one variable (light, water, or temperature) to explore differences in the germination preferences of the plants. If film canisters aren't available, other small, opaque containers with lids can be substituted.

During this project, students will be working to cooperatively create a field guide to trees in the neighborhood near the school. In doing so they will be making observations, introduced to tree and plant anatomy and physiology, and will learn how to make and use dichotomous keys.

This activity is a field investigation where students make observations of the pebble beach, lava flows, and wetland restoration at Sugarloaf Cove to generate questions to be addressed throughout the earth science curriculum.

This activity will help students learn about Minnesota animals and characteristics that distinguish them from one another.

This interactive visualization created by FRED (Free Energy Data), displays energy supply (by source) and demand (by use) for each state in the US from 1960 to 2010; forecasts through 2035 are available as well. FRED is an open platform to help state and local governments, energy planners and policy-makers, private industry, and others to effectively visualize, analyze, and compare energy-use data to make better energy decisions and form sustainable strategies.

This activity is a field investigation where students will learn the importance of detail when nature journaling.

This activity is a field investigation where students investigate the water quality of a local stream or pond.

This activity is a learning game in which student teams are each assigned a different energy source. Working cooperatively, students use their reading, brainstorming, and organizational skills to hide the identity of their team's energy source while trying to guess which energy sources the other teams represent.

In this investigation, students gather biotic and abiotic data and samples in the field, develop an experiment to test another abiotic factor in the lab, synthesize group data, interpret their findings and make a claim on the health of the wetland ecosystem.

In activity is a Biology field lab where students will investigate the relative health of an aquatic system based on bioindicators. Students will then summarize and reflect upon their findings.

This activity is a field investigation where students gather data on ponds and compare the results to determine the quality of the water.

This activity is a field investigation where students learn about scientific sampling, earthworms as an invasive species, and collect data on earthworm populations using three sampling methods.

This article describes energy efficiency as it relates to home and school energy use and provides ways that children can help.

This activity is an interactive lecture, where students will learn that fresh water is a limited resource. They will also see that drinkable water is not distributed evenly over the earth.

This activity is a field investigation where students find real-life examples of erosion in their school surroundings. Students will extend what they learned during stream table lessons about erosion, deposition, deltas, meandering streams, and dams.

This flow chart shows the sources and activities across the U.S. economy that produce greenhouse gas emissions.
