Isopods
Source Institutions
In this outdoor activity, learners dig for and collect isopods (sometimes known as "roly-poly bugs" or "potato bugs" and other names).
The Length of My Foot
Source Institutions
In this math lesson, learners explore the concept of using units to measure length. Learners first read "How Big is a Foot" by Rolf Myller and learn about units.
Saldo Island: An Unfair Game
Source Institutions
In this environmental science activity about biodiversity, learners play a game to discover the effects of non-native species on an ecosystem.
Animals in a Grassland
Source Institutions
In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.
Snug as a Bug
Source Institutions
In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.
Jumpin' the Gap
Source Institutions
In this simulation of synapses, learners act out communication at the neural level by behaving as pre-synaptic vesicles, neurotransmitters, post-synaptic receptors, secondary messengers and re-uptake
Macro-Microarray
Source Institutions
In this activity, learners explore the "nuts and bolts" of gene chips.
The Carbon Cycle and its Role in Climate Change: Activity 1
Source Institutions
In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.
A Recipe for Traits
Source Institutions
In this genetics activity, learners create and decode a “DNA recipe” for a dog by randomly selecting strips of paper that represent DNA.
Ocean Home: Swimming Fishes
Source Institutions
In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.
Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
Crime Scene Investigation (CSI) with Powdery Mildew Fungi
Source Institutions
This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.
Who Dirtied The Water?
Source Institutions
In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).
OBIS Oil Spill
Source Institutions
In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
Jay Play
Source Institutions
In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.
Food for the Brain
Source Institutions
In this activity, learners dissect a piece of pizza to learn about nutrients important for health.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
Food Grab
Source Institutions
In this outdoor activity, learners design devices that will catch prey or gather plants.
Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
Cool It
Source Institutions
In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.
