The Making of the Fittest: The Birth and Death of Genes
Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

The Colligative Properties of Solutions
How can you relate colligative properties of solutions to everyday situations? Pupils first discuss the concepts of density, boiling and freezing points, then demonstrate how to accurately determine the boiling and freezing point of...

TE Activity: You're in Hot Water
Students study different ways of using solar energy. They design a solar water heater and determine how much water it can heat in a set amount of time. They examine how the heaters work by solar radiation and convection.

Frozen Fish? Unique Adaptations of Antarctic Fish
Some fish contain proteins that act like antifreeze in order for them to live in the frigid waters of Antarctica! High schoolers determine how much antifreeze a fish needs to lower its body temp to -2.5 degrees. Teachers act as a...

Icefish Blood Adaptations: Antifreeze Proteins
Ever wonder how fish survive in freezing cold water—especially Antarctic waters? Some fish have an adaptation that lowers the freezing point of their life fluids. Learners model these adaptations in two lab explorations. The first...

Antifreeze - Anti Fish
Students participate in the production of a play that highlights the direct linkage between storm drains and natural river, stream, or creek ecosystems. They explore their thoughts, feelings, and actions through dramatic interaction and...

Inquiry into Consumer Products
Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Match Words: Toxins
For this toxin matching activity, students draw a line from a toxin to a picture that shows where it might be found in a home. Students then match 5 words [toxins] to their descriptions.

Oceans of Energy
Are the earth's oceans really just giant batteries, waiting for their energy to be harnessed? Middle school mechanical engineers will be shocked by the amazing amount of energy that forms around them after diving into part four of a...

Adaptations of Fishes for Survival in Polar Environments
Students compare the anatomy of temperature and polar fishes. They explore the adverse effects of cold on metabolism and physiology and discuss how polar fishes adapt to their environments. Comparisons are also made to the DNA sequences...

A Long Winter's Nap
Students explore the process of estivation, hibernation and torpor and the ways that frogs adapt to seasonal weather changes.
Curated OER
Freezing Point Depression
Students create ice cream in a zipped bag and measure the temperature of a salt/ice mixture. They discover how salt lowers the temperature necessary to freeze ice to a solid (below 0'C).
Curated OER
Color, Light, and Excited Electrons
Investigate color, light and excited electrons and produce waves using slinkys. Your high schoolers will observe a continuous spectrum with a prism and an overhead projector. They observe flame tests to identify elements and they observe...

Winter Survival/Hike
Hibernation isn't just about staying fed, it's about staying warm. Young environmentalists explore the importance of staying warm in the wilderness with a short lesson about surviving in the wild. Using gelatin to represent warm-blooded...

What Is the Freezing Point?
Students remove heat energy and determine how it causes a phase change.

Concrete Lesson Plan
Students describe the difference between cement and concrete. In this technology lesson, students explain the mixing process of concrete. They discuss its importance in the modern world.
