Nature Through the Eyes of Generations

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

Are you the predator or the prey? Student groups participate in an activity to demonstrate the process of natural selection in a contained environment. After scholars complete the activity and questions, they apply their knowledge to a...

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

The lecturer describes how certain characteristics develop. In this case, he discusses eye marking. The impact of environmental factors plays a huge role in the probability of successful reproduction and the fact that favorable genes...

If you carefully observe populations with short life cycles, you can observe natural selection happening. The video explains what natural selection is, how scientists theorized it, and how science proves the concept. It highlights the...

Examine exactly what is meant by natural selection, as well as how it works in nature and through the assistance of humans. Presented with fun graphics and simple narration, the complex topic of natural selection is clearly explained in...

Cameras are amazing tools that enhance the way we see the world. From capturing time-lapse footage of seeds sprouting or seasons changing, to high-speed photography showing a bullet crashing through its target, cameras allow us to see...

Electricity is an integral part of our daily lives, but many energy sources are damaging the environment. Young engineers read about innovations in alternative energy sources, then work in groups to design and build a model of a system...

Beginning with a general discussion about natural gas, methane, and hydrocarbons, a few videos and diagrams are projected to support the lecture. Individuals participate in a brief activity by drinking juice through a straw, and then...
