Lynx Eats the Hare— Super Value Kit
Students see what happens when an area becomes over-populated or when food is limited. The life cycles of 20 generations of lynx and hares are observed and graphed to identify trends in the population growth. Kit includes five decks of Lynx Eats the Hare cards, detailed instructions, student work- sheets and complete teacher notes.

How a Food Web Is Formed— Super Value Game
Use this game to help students learn how organisms are related in a food chain or web. Students view more than 120 organism illus- trations, study characteristics and determine “who eats whom” as they assemble a food chain from a deck of special habitat cards.
As more organisms are selected, the food chain develops into a complex food web.

The Grass Won’t Grow— Student Laboratory Kit
Why does grass grow in one area and not another? In this activity, seeds are planted in two different environments and the results of growth compared. Using the scientific method, students define the problem, make observations, develop a hypothesis, design and conduct an experiment, analyze data and draw a conclusion.

Prey vs. Predator Kit—Win, Lose or Draw? Super Value Kit
What happens when various organisms living in one habitat are all trying to survive and produce offspring? Will they all survive and reproduce or will only some win, some lose? This fast-paced activity has student “preda- tors” attempting to capture their “prey” while discovering that the relationship between prey and predator species and the environ- ment is critical to survival and reproduction.

Plants & Pollutants— Student Laboratory Kit
What are pollutants to plants? How concen- trated do pollutants have to be to affect plants? Students experiment with different types of chemicals on radish seeds and discover answers to these questions. Teacher Notes, reproducible student handouts and all necessary chemicals and specialized equipment are provided.

Plants in the Spotlight—
A Photosynthesis Investigation— Student Laboratory Kit
This cooperative class activity explores whether plants prefer certain wavelengths of light for photosynthesis and how envi- ronmental conditions affect the rate of photosynthesis. Using Hornwort, an aquatic plant, groups experiment with different variables to investigate changes in the rate of photosynthesis. Class data are pooled, graphed and analyzed. Includes chemicals, test tubes and colored filters for 30 students working in groups of three. Hornwort is available separately.
