What's New With Dinosaurs?

Remind your middle school scientists how fox ear size varies depending on the climate they live in; large ears allow heat loss while small ears keep heat in. Discuss how a cold-blooded animal might try to regulate body temperature. Then...

Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Students investigate the effect of temperature on cold-blooded animals, using a 5 x 8 inch index card to represent a dinosaur as their model organism. Students measure temperature changes that occurs at different angles to a light...

Scientists believe confuciusornis developed a beak and lost teeth as a key step in the evolutionary process. Learn more about confuciusornis and other birds, dinosaurs, and animals that evolved into the birds of today. PBS Eons walks...

Students use relevant evidence and logical reasoning to construct theories for dinosaur behavior. They examine recent evidence that challenges a prevailing dinosaur theory.

Scientists have never known if dinosaurs should be called warm-blooded or cold-blooded animals. Learn about the surprising new discovery that has shed light on the answer to this question.

After listening to your lecture on climate change, young scientists access NOAA's database listing Mauna Loa's carbon dioxide data. They graph the monthly means and then compare their graphs to NOAA's. This is a concise plan that could...

Discover the environmental and economic impact of global warming. After reading an article, emerging environmentalists identify how different countries are responding to the Kyoto Protocol. They research emission laws and write a news...

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Discuss with your oceanographers what forces cause nearshore upwelling and downwelling. Display a line of wind vectors alongside a graph of the temperatures so that they can discover whether or not they are related. Discussion questions...
