This video segment, adapted from ZOOM, demonstrates how to use a drinking straw and a bottle full of water to make low- and high-pitched sounds.
In this interactive periodic table from the NOVA Web site, find out the role of various elements in making fireworks.
How does energy flow in and out of our atmosphere? Explore how solar and infrared radiation enters and exits the atmosphere with an interactive model. Control the amounts of carbon dioxide and clouds present in the model and learn how these factors can influence global temperature. Record results using snapshots of the model in the virtual lab notebook where you can annotate your observations.
Measure relative humidity in the air using a simple device made of a temperature sensor, a plastic bottle, and some clay. Electronically plot the data you collect on graphs to analyze and learn from it. Experiment with different materials and different room temperatures in order to explore what affects humidity.
Featuring slow-motion footage of insects in flight, this video adapted from NOVA explores the engineering challenge of designing a robotic aerial vehicle that flies like a bug.
In this video adapted from the Encyclopedia of Physics Demonstrations, learn how plotting the changes in an object's position on a graph can provide information about the object's motion.
Learn about rotational forces by watching astronaut Jeffrey Williams spin objects onboard the International Space Station in this interactive activity adapted from NASA.
