C. B. Atlas Animations: Temperature Experiments

Get young biologists' hearts pumping with this invigorating experiment on homeostasis. Working in small groups, one student performs jumping jacks for eight minutes while the other group members regularly record the person's vital signs,...

Develop a formula based upon numerical computations. The 31st part of a 33-part unit has the class determine the formula to convert a temperature in Celsius to a temperature in Fahrenheit. They do this by making comparisons between the...

A toolkit is something that has what you need to fix or make something. You just clicked on a teacher's toolkit for introducing the concept of coral bleaching in relation to climate change and changing sea temperatures. In it, you will...

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

Ever wondered what roundworms like? Or what they don't like? Explore the sensory preferences of C. elegans through this controlled chemotaxis experiment. Biology class members brainstorm what substances might attract — or repel — the...

Class members are introduced to probability using terms such as impossible, unlikely, likely, and certain. Numbers between zero and one are associated with the descriptions of probability. Pupils find the likelihood of chance experiments...

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

Is it instinct and intelligence that divide animals from humans? What are they really thinking, and how do we define that? Check out this great video that discusses everything from Descartes' thoughts on the topic and Darwinian evolution...

While clouds may not make for the most enjoyable weather, they play an important role when it comes to regulating the temperature of the earth. Watch this video and learn how these giant masses of water droplets actually help to cool the...
