This video segment adapted from NOVA describes the emergence of life on the islands of Hawaii from a barren volcanic platform under the ocean waves to the rich explosion of life that covers the many climate zones of the islands today. [5:13]
This video, adapted from NOVA, showcases the competing engineering plans designed for landing a person on the Moon for the first time. [5:26]
This resource provides directions for a lab in which students observe changes in a gene pool of bunnies affected by natural selection. Includes PDF resources.
Find out how this paleontologist believes dinosaurs rose to higher grounds following a mass extinction hundreds of thousands of years ago. [36:38]
Learn how genetic disorders are passed from parents to children as explained in this excerpt from Blazing a Genetic Trail, from the Howard Hughes Medical Institute.
In this video segment adapted from Shedding Light on Science, students will observe demonstrations of the fundamental idea that light travels in straight lines. [1:57]
By viewing high-speed videos of raindrops hitting mosquitos, learn how insects are able to fly in the rain by calculating the impact forces of raindrops on flying mosquitoes.
Bacteria reproduce asexually. This means that, when a bacteria cell splits, both halves of the split are identical -- they contain exactly the same DNA. The offspring is a clone of the parent.
In this fast-paced NASA Brain Bites video, an astronaut demonstrates the impact of microgravity on the use of tools in space. [0:47]
Join Nick Anderson on a tour of the technology that powers a planetarium, and even sneak behind the dome for the ultimate inside peek at astronomical action! Worksheet available for grades 3-4.
In Blazing a Genetic Trail, by the Howard Hughes Medical Institute, follow this three-step approach to treating genetic diseases.
Museum craftsmen Carl and David explain how they create casts of Australopithecus afarensis fossils to display in the Museum. Worksheet available for grades 3-4.
We know the universe is expanding, but how? This adapted video segment, using footage from NOVA and NASA, examines Edwin Hubble's work and how his findings laid the foundation for the Big Bang theory. [3:22]
In this video segment adapted from NOVA: "Judgment Day: Intelligent Design on Trial," students will learn how modern genetics and molecular biology offer compelling support for evolution. The video features an interview with biologist Ken Miller. [3:26]
An archaeologist explains how the bones of early humans can reveal information about their diets. [29:15]
This StudyCards stack enables students to review the vocabulary used in studying human genetics.
This video segment from Evolution: "Darwin's Dangerous Idea" shows biologists Chris Schneider and Tom Smith studying hummingbirds and other animals in Ecuador. Their research is investigating the processes by which new species are formed.
Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. This pair of cartoons explains how to balance chairs on brooms and potatos on forks!
View videos and photos from the aftermath of Hurricane Matthew and see how the earth's landforms changed as a result of the heavy winds and rain. Weathering and erosion made a new landform and dramatically changed the coastline. Background information is available for teachers, along with teaching tips and activities.
