Learners conduct a simulation to explore how scientists estimate the size of animal populations. They analyze a random sample and then extrapolate those results to a larger population. Additionally, they will apply the principals of...

Students examine and categorize plants in their own schoolyard desert garden and then observe other plant areas of their schoolyard.

Students are assigned a separate species of plant or bird to research. Using a worksheet, they are responsible for finding a variety of information on their assigned plant or bird. They also complete a mini-poster and give an oral...

Students identify possible sources of health risks, types of exposures, routes of exposure, and populations that could be affected after discussing water pollution and environmental health hazards. After discussion, students conduct a...

Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

These twenty various types of questions related to the cycling of matter and energy require students to match each definition in column 1 with the correct vocabulary term from column 2. Then, students explain what is being demonstrated...

Begin by showing a six-minute video, Changing Planet: Rising Sea Level as an anticipatory set. Pupils draw a topographic map of a potato continent. Finally, they will visit NOAA's sea levels online map and NASA's carbon dioxide...

How many of us can say they've seen a Pacific walrus? Not many and one of the reasons is the impact of climate change on their aquatic environment. Children get to think about the food web of the Bering Sea by creating an actual web with...

Here's a stat for your pupils: 18 percent of the human body is carbon! Part 10 in the series of 12 takes pairs on an adventure through the carbon cycle. After a class reading about carbon, pairs read and choose their own adventure...

A change in a parameter can end in overpopulation. The resources gives pupils the opportunity to control the parameters of rabbits and wolves in a natural setting. Using the set parameters, the simulation runs and displays the population...

Nanoparticles have toxic effects on plant and animal life—even though you can't see them. The second lesson of a two-part series has young scientists conduct an experiment that exposes plant and animals to nanoparticle pollutants. They...

Scholars read a brief overview of what a terrarium is and how it creates the greenhouse effect, then click on a link to discover the materials and 10 steps they need to build their own.

Learners use topographic maps to delineate a watershed.In this ecology lesson, students draw the boundaries of a watershed onto a map using contour lines as a guide. Their resulting maps are used to evaluate their understanding.

Learners research trees and their parts. In this forestry lesson, students participate in various learning stations to identify trees by matching the photographs of the tree to the correct name.

Eighth graders measure irregular and regular shaped solids.  In this investigative activity students calculator volume, mass and density of wood and blocks.

Fourth graders identify parts of a fish. In this fish anatomy lesson, 4th graders identify parts of fish in a group setting and then complete a worksheet about the parts of a fish.

Sixth graders explore ways to analyze the properties of water and examine the chemistry of water.  In this water instructional activity students work in groups and complete several activities. 

Sixth graders explore how water behaves on a penny.  In this states of matter lesson, 6th graders observe water as they add drops to a penny. This lesson helps students apply the adhesive properties of water to the water cycle.

Students engage in a discussion on watershed management.  In this ecology lesson, students consider the role of forests in water quality.  Students incorporate lecture material into a class room discussion and...

Students classify animals. In this animal classification lesson, students identify characteristics from each of the 5 categories of vertebrates. Students group animals by categories.

Middle schoolers identify the different tropical rainforests in the world using a map. In this ecology lesson, students describe the different methods of deforestation. They create a memo and present it to class.

Students explain that there are pollutants in the Anacostia River, what those pollutants can cause, and how to prevent further pollution. They read about pollution and graph levels of fecal coliform in the water.

Have you been wondering how to use that natural trail at or near your school? This activity gets kids outside with a purpose: learn about ecological succession through field observations and collecting seed and soil samples. The resource...

Scientists listen to the story of Wadja Egnankou who works to save African mangrove forests. They experiment with refraction and the introduction of particulate matter to water. They conclude with creative writing about the need for a...
