Wetland Loss: Digging of Canals

A happy discovery occurred in Arkansas in 2004: a woodpecker, believed to be extinct since the 1940s, reappeared! Or did it? Middle to high school ecologists examine scientific evidence and use critical-thinking skills to determine...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

Feeling high is not the only side effect of abusing prescription opioids. Middle and high schoolers learn more about specific painkillers, including Fentanyl, Oxycodone, and Clonazepam, as well as their common brand names and extensive...

We can't dig a hole through the Earth, so how do we know about the layers beneath our feet? Scholars learn about layering through hands-on exploration of common materials. They study the characteristics of each layer and apply their...

Create a coat of armor for dinosaur volunteers. Young scientists explore the oxidation-reduction reaction facilitated by electric current. The result of the reaction is a dinosaur coated in copper and zinc, which leads to an...

Students study how to measure and calculate the volume of water flowing down a stream or canal and use simple tools to make measurements. Next, students determine how many people cold live off the volume of water measured. Finally, they...

Students examine the topic of high altitude climbing. They discover what happens to the human body at a high altitude. They examine different conditions that can occur.

Students observe subsidence and the effect it has on wetlands with a classroom demonstration. They think about the impact of global warming and the sea level and how it affects the marsh.

Penguins, seals, and whales have countercurrent heat exchangers to limit blood flow in certain areas of their body, limiting their rate of heat loss to their environment. In this homeostasis video, the instructor explains that...

Build a strong foundation for your teaching of stability and change! The video addresses the Next Generation Science Standards Cross-Cutting Concept through insightful examples. The narrator includes ideas for introducing the standard in...
