Arctic Smorgasbord!
Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

What Can We Learn from Sediments?
Varve: a deposit of cyclical sediments that help scientists determine historical climates. Individuals analyze the topography of a region and then study varve datasets from the same area. Using this information, they determine the...

Down to the Deep Virtual Lab
At a depth of 3,000 m in the ocean, the pressure is 300 times that at sea level! In the activity, individuals predict what will happen to Styrofoam cups submerged 3,000 meters into the ocean. They then convert these units to soccer...

Polar Detectives: Using Ice Core Data to Decode Past Climate Mysteries
How does examining an ice core tell us about weather? Learners set up and explore fake ice cores made of sugar, salt, and ash to represent historical snowfall and volcanic eruptions. From their setups, scholars determine what caused the...

Artificial Hearing
Your sense of hearing depends upon tiny hairs deep inside your ear and if you lose these hairs, you lose your hearing. Here, groups explore hearing through the decibel measurement of common sounds. As a class, participants discuss...

The Carbon Cycle
When it comes to the carbon cycle, the sky really is the limit. The lesson begins with observing a closed ecosystem in a bottle. Then, scholars discuss and answer questions on the carbon dioxide and oxygen cycles.

Schoolyard Biodiversity Investigation Educator Guide
In 1980, in the tropical rainforests of Panama, scientists discovered 1,200 species of beetles living in and around just 19 trees, with most of the species new to science—that's biodiversity! In the activity, learners work in teams to...

Artificial Eye
Scientists in California developed a bionic eye that allows blind people to see edges of objects in black and white and costs $145,000. In the activity, groups of scholars discuss bioengineering, focusing on the human eye. They then...

The Carbon Cycle
Scholars learn about the carbon cycle, play a carbon cycle game, and then write a story based on their role as a carbon atom during the game. After the writings, pupils analyze the carbon cycle by leading a class discussion on the material.

Building Your Own Biosphere
On September 26, 1991, four women and four men entered the scientific experiment, Biosphere 2; the doors were sealed for two years in order to study the interactions of a biosphere. In the activity, scholars explore biospheres by...

The Carbon Cycle
Carbon is the fourth most abundant element in the universe (in terms of mass), behind hydrogen, helium, and oxygen. Scholars learn about the carbon cycle, from ways carbon is removed from the atmosphere to how it is added in an 18-slide...

Curb the Epidemic!
Class members use an applet on the Internet to simulate the spread of a disease. The simulation allows individuals to determine two nodes to vaccinate to limit the number of nodes infected. By running several simulations, scholars can...

Investments in Forest Carbon
One hundred metric tons of CO2 can accumulate in one acre of forest over time—that's a lot of carbon! In the activity, groups of middle school learners determine what makes forests important. They then solidify the concept by using a...
