This activity is an outdoor lab where students gather data and calculate velocity, acceleration, momentum, and force of a vessel they create to safely deliver 2 eggs from the roof to the pavement below.

Students test the question, "Do eggs balance on the equinox?" Students develop their own procedure, analyze their data and come up with their own conclusions.

The CyberSquad must construct a clock of sorts in order to keep track of the amount of time they have to rescue Dr. Marbles in this video segment from Cyberchase.

This video, adapted from NASA, presents rare experimental evidence from the Fermi Gamma-ray Space Telescope supporting Einstein's prediction that space-time is smooth.

Students model, build, and draw diagrams of electric circuits and test the conductivity of a variety of materials.

This is a series of lab activities where students complete experiments for open, closed, series and parallel circuits.

This simple demonstration shows the interaction between electricity and magnetism. Two coils of wire are held close to each other, but not touching. One is attached to a music source, such as a small radio or iPod, and the other is attached to an external speaker. Students can hear the music through the speaker even though there is no direct connection.

This activity is a simple way for students to understand the basics of electron energy levels, a fundamental atomic concept.

The interactions of electrons with matter have great explanatory power and are central to many technologies from transistors, diodes, smoke detectors, and dosemeters to sophisticated imaging, lasers, and quantum computing. A conceptual grasp of the interactions of electrons in general allows students to acquire deeper understanding that can be applied to a very broad range of technologies.

In this animation produced by WGBH and Digizyme, Inc., see how molecules of DNA are separated using gel electrophoresis, and how this process enables scientists to compare the molecular variations of two or more DNA samples.

Use a series of interactive models and games to explore electrostatics. Learn about the effects positive and negative charges have on one another, and investigate these effects further through games. Learn about Coulomb's law and the concept that both the distance between the charges and the difference in the charges affect the strength of the force. Explore polarization at an atomic level, and learn how a material that does not hold any net charge can be attracted to a charged object. Students will be able to:

An interactive lecture demonstration intended to help students use physics reasoning to predict the outcome of a puzzling electrostatics demonstration.

The students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as they assess various everyday objects to determine what forms of energy are transformed to accomplish the object's intended task. The students use block diagrams to illustrate the form and state of energy flowing into and out of the process.

In this lesson designed to enhance literacy skills, students examine energy forms in moving objects and discover how changes from one form to another move cars through a roller coaster ride.

On NOVA, a team of carpenters, timber framers, engineers, and historians recreate a medieval throwing machine called a trebuchet. This adapted video segment explores how understanding energy transfer informs their design.

This issue of the free online magazine, Beyond Penguins and Polar Bears, explores the Sun's role in warming Earth, the albedo (reflectivity) of Earth's diverse surfaces, and how the decline of Arctic sea ice is affecting Earth's energy balance. Science lessons introduce the concepts of solar energy, reflection, and absorption to elementary students. The issue also includes an overview of the natural resources and energy sources found in the polar regions as well as lessons that allow students to develop the concepts of natural resources, energy sources, and energy efficiency.

This article assembles free resources from the Energy and the Polar Environment issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

This article highlights children's literature about light, heat, and energy sources for use in the elementary classroom.

See potential energy convert to kinetic energy in this interactive activity from WGBH that shows a roller coaster in action.

Students are introduced to genetic techniques such as DNA electrophoresis and imaging technologies used for molecular and DNA structure visualization. In the field of molecular biology and genetics, biomedical engineering plays an increasing role in the development of new medical treatments and discoveries. Engineering applications of nanotechnology such as lab-on-a-chip and deoxyribonucleic acid (DNA) microarrays are used to study the human genome and decode the complex interactions involved in genetic processes.
