Leave it to Beavers
Many people know cats mark their territories by rubbing the back of their necks to leave a scent, but not many people know beavers also leave a scent to mark their territories. During the first activity of two, scholars use their noses...

Subalpine Web
The theory of keystone species in an ecosystem was first established in 1969 by Robert T. Paine. Pupils open the final lesson in a five-part series with a game guessing which member of the alpine ecosystem they are based on clues. After...

Plant Groups
Bryophytes can grow in temperatures just above zero degrees. This 17th installment in a series of 20 introduces learners to the five groups of plants: algae, bryophytes, pteridophytes, gymnosperms, and angiosperms. Classes then explore...

Plant Features
Pine needles are actually modified leaves. In the 16th installment of 20, young scientists explore plants. Through an analysis of leaves — shape, veins, and edges — pupils see how to classify plants based on structural features.

Invertebrates
Of all invertebrates, insects by far are the most numerous. Scholars discuss invertebrates and then use a key to classify them. They see different examples and must describe features of each organism based upon the key.

Is it Alive?
Interestingly enough, movement is not a characteristic of living things. The first activity in a series of 20 introduces learners to the concepts of living versus non-living things and then focuses on biologists and what they study....

It Was a Very Good Year
Waterton-Glacier International Peace Park includes whitebark pines that are over 1,200 years old, meaning they have been there since before medieval times. The second lesson of five details how to read tree rings for climate change and...

History of Plant Classification
Bamboo, the fastest growing plant in the world, can grow up to 35 inches in one day! Pupils learn how plants historically have been classified and determine if these traits are appropriate to use in this 17th lesson of 20. They will also...

The Mangroves
Mangroves are a nursery for a variety salt-water organisms. Learners explore the mangrove ecosystem through audio, video, and/or images, to see the organisms that live in this environment and make food chains pertaining to this...

Photosynthesis
Venus fly traps photosynthesize and consume insects because the soil they live in does not provide enough nutrients. Scholars analyze historical scientific experiments to learn how scientists discovered photosynthesis. From their...

Plankton Parents
Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three.

Talk Story: A Native Way of Knowing
The steps of the scientific method examine a problem, make a prediction, and attempt to solve the problem—similar to the path most stories take. In the activity, individuals see how stories can explain natural events similar to the way...

Calorimetry Lab
Young people between the ages of 11–13 need on average about 2,000 calories per day. Within the lab, groups learn about calorimetry and respiration. They explore how it pertains to humans and animals living the Arctic where cold...

How Much Data is Enough?
The next time you read a magazine or watch the news, make note of how many graphs you see because they are everywhere! Here, scholars collect, enter, and graph data using computers. The graphs are then analyzed to aid in discussion of...

Bering Sea Fabulous Food Chain Game
In spring, the Bering Sea turns green due to phytoplankton, which live at the surface, experiencing a population explosion. Groups of scholars play a food chain game, writing down food chains as the game is played. After five to six...

Rings of Life
Individuals analyze tree rings to determine the health of an ecosystem. They then look at otoliths of fish, hard calcium carbonate structures located behind the brain, in the same manner.

Who Will Melt First?
If the Greenland ice sheet melted, sea levels would rise by about 20 ft; if the Antarctic ice sheet melted, sea levels would rise by 200 ft. Scholars explore ice melting through the analysis of different ice samples, clean and dirty ice....

Is There Salt in a Glacier?
What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts.

Can Carbon Dioxide Act Like a Greenhouse Gas?
Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

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...

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...
