This illustrated essay from A Science Odyssey Web site explains the science behind radio waves, including the role of electrons and electromagnetic fields.
In this video segment adapted from Shedding Light on Science, observe demonstrations of the fundamental idea that light travels in straight lines.
Use the Sound Grapher to create visualizations of sound and learn about the frequency, wavelength, amplitude and velocity of sound waves.
In this fast-paced NASA Brain Bites_íěÖ video, an astronaut demonstrates the impact of microgravity on the use of tools in space.
This video segment adapted from A Science Odyssey looks at the invention of nylon.
In this video segment adapted from NASA, astronomer Michelle Thaller introduces the world of infrared light and demonstrates how infrared cameras allow us to see more than what the naked eye can perceive.
This is a guided inquiry discussion to introduce machines and to identify types of simple machines
In this hands-on inquiry activity, students will design and construct an apparatus that will permit an egg to survive a nine foot fall. Students are given limited materials, so they must critically think about the design and improvise strategies during the building of the apparatus
This animation from KET's distance learning physics course demonstrates the mathematical formula for a scientific law as it applies to light.
This activity is a indoor lab where students investigate the current differences in different circuits where students build a small house and construct different types of circuits.
This is an exploratory activity involving matter and density. There are many assessment pieces including a laboratory.
This guided inquiry activity helps students differentiate between heat and temperature and goes on to relate specific heat to thermal conductivity.
Students use media resources and an in-class investigation to explore the types of energy within different types of systems. They also use the formulas for kinetic and potential energy to examine the path of a projectile.
This activity is an activity where students build a motor, learn motor operation and theory, interpret their understanding through troubleshooting, and develop a new, experimental question related to the motor. One follow-up activity would be coupling their motor to a fan blade or other axle to convert electrical energy to magnetic energy into mechanical motion for real world application.
This physics lab activity is an introduction to Simple Harmonic Motion, utilizing the variables of mass, length, and angular displacement to determine their effect on period. Acceleration of gravity is calculated and the results of manual data collection and Vernier LabPro data collection are compared.
In this video segment adapted from ZOOM, the cast builds a suspension bridge from a couple of chairs, some cardboard, and rope.
In this interactive activity from ChemThink, learn how ionic bonds are formed and how an ionic bond structure is represented by its formula.
This activity lends itself well to the review and repetition of previous topics and skills. The multi-faceted learning (and display of learning) is an excellent manner of getting the students to think about what they are doing and how they are answering.
In this video segment adapted from NOVA scienceNOW, follow scientists in their quest to understand how stable elements are made and how to create the elusive element 114.
This issue of the free online magazine, Beyond Penguins and Polar Bears, examines physical science concepts, such as heat, conductors, and insulation, and applies this knowledge to the animals and people in the Arctic and Antarctica.
