Abuse-a-Cyst
Source Institutions
In this activity, learners examine how brine shrimp populations can survive in some of the harshest environments.
Build Your Own Wind Turbine
Source Institutions
Learners construct an electricity-generating wind turbine out of a plastic bottle.
Algae in Excess
Source Institutions
Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.
Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.
Catch & Release II: It's Catching On!
Source Institutions
Throw that fish back? A new generation of ethical anglers concerned about conserving resources is participating in "catch and release" fishing. How is this going?
Healthy Habitats Have Native Plants
Source Institutions
In this activity, learners help identify native and non-native plant species, learn about invasive species, and determine how native plants provide a healthier habitat.
Envirolopes
Source Institutions
In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.
Observing Insects at Night
Source Institutions
In this activity, learners set up a night time insect observation station with a light and sheet.
Evolutionstechnik or Selection and Variation in the Egyptian Origami Bird (Avis papyrus)
Source Institutions
In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s
The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
See the Light
Source Institutions
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
Inverted Foucault Pendulum
Source Institutions
In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.
Acid Rain
Source Institutions
In this chemistry demonstration, acid rain is simulated in a petri dish.
Clipbirds
Source Institutions
In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.
Biological Succession in a Microecosystem
Source Institutions
This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.
Rock Bottoms
Source Institutions
Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.
Introduction to Ocean Zones
Source Institutions
In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.
Salt Water Revival
Source Institutions
In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.
Burning Issues
Source Institutions
Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.
Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
