In this video segment from NatureScene, observe dragonflies and mayflies near Cedar Creek at Congaree Swamp National Park.
In this video segment adapted from A Science Odyssey, follow two scientists and their Nobel Prize-winning efforts to cure bacterial infections using penicillin.
In this video segment from Cyberchase, the CyberSquad breaks down an action into a series of steps in order to program a robot to do what they need it to do.
Blast a Buick out of a cannon! Learn about projectile motion by firing various objects. Set the angle, initial speed, and mass. Add air resistance. Make a game out of this simulation by trying to hit a target.
In this media-rich, self-paced lesson, students explore some of the technologies designed to detect and treat inherited diseases and the ethical debate surrounding them.
Grade 2: Module 4 of the EL Education K-8 Language Arts Curriculum. In this module, students build their literacy and social-emotional skills through the analysis of literary and informational texts, as they engage in a study of how to care for and conserve the world of pollinators. For more information on getting started with the curriculum, please visit https://curriculum.eleducation.org.

In this interactive periodic table from the NOVA Web site, find out the role of various elements in making fireworks.
Watch quantum "particles" tunnel through barriers. Explore the properties of the wave functions that describe these particles.
When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns they produce on the screen.
In this video segment adapted from NOVA scienceNOW, learn about RNAi's potential to treat a wide range of genetic and infectious diseases.
Broadcast radio waves from KPhET. Wiggle the transmitter electron manually or have it oscillate automatically. Display the field as a curve or vectors. The strip chart shows the electron positions at the transmitter and at the receiver.
Explore forces, energy and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work.
This video segment from Nature features ravens, the most intelligent birds in the crow family.
This video segment from NatureScene describes the characteristics of redwood trees at Redwood National Park.
In this lesson designed to enhance literacy skills, students learn about the advantages and disadvantages of the two basic forms of reproduction for the living things that practice them.
In this video segment adapted from NOVA, learn about the critical role of flowers in seed plant reproductive biology.
In this video segment from NatureScene, discover some reptiles in the swamp forest ecosystem at Congaree Swamp National Park.
This interactive activity adapted from the Wisconsin Online Resource Center challenges you to plan, measure, and calculate the correct amount of roofing material needed to reroof a house.
In this video produced for Teachers' Domain, meet Sandra Bustamante, a university research assistant who started her career with a biotechnology certificate and is now using nanotechnology—rather than needles—to deliver vaccines.
Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire.
