Students will identify wind power as a source of energy and use the engineering process to determine construction of the blades, the housing unit and wind power enough volts to light one LED light bulb.
Students will learn about various careers related to energy. Students will learn about specific energy careers based on their interests.
The topic of this video is energy in general, and specifically the ways we can quantify it. In order to make the concepts accessible to a broad audience, this video focuses on everyday things and events. How is it that energy plays a part in a child riding a scooter? How is the energy we consume in playing related to the energy on the food we eat? This video poses these questions to the class and challenges them to put a list of five such items into an ordering from most energy to least.
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.

There are several tutorials on the page for this link. This review is under the subheading "Momentum and Energy." It is a small group tutorial that leads students through the construction of an understanding of the concept of momentum and its conservation.
Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters. This simulation is best used with teacher guidance because it presents an analogy of chemical reactions.

This video segment from IdahoPTV's D4K lists, describes and shows examples of the 6 simple machines and how they make work easier.
In this video segment adapted from NOVA scienceNOW, learn about engineering innovations that could help detect a bridge's structural weaknesses before they become dangerous.
This video segment adapted from NOVA/FRONTLINE looks at American energy consumption and the resulting production of greenhouse gases.
In this video from DragonflyTV, follow the investigation of Isaac and Anjali as they record, measure, and analyze data about how the Sun's position in the sky affects a solar-powered car's speed.
Students will identify photovoltaic solar power as a source of energy and explain what happens when a photovoltaic cell is shaded.
In this project, students will use knowledge of electricity and electromagnetism to collaboratively design and test a model of a magnetic recycling sorter. They will evaluate the performance of their models and propose further modifications based on the output of their magnetic device measured in mT using a Vernier probe. They will also physically test their magnets on a model of a conveyor belt containing recyclable items. Students will track their data from both tests, with the ultimate goal of creating the strongest and most effective magnet with given materials. Finally, students will present their findings and proposed final design to peers and community partners involved in the recycling industry. The entire process takes about 6 weeks. The unit is a great fit for standards within energy and engineering & design.
This interactive quiz from the NOVA Web site features an array of interesting facts about the nature of sound underwater.
This video segment, adapted from ZOOM, explores how sound waves travel differently through solids than through air, in this case, a metal clothes hanger.
This video segment adapted from Shedding Light on Science uses historical illustrations and everyday examples to show that light has a speed and does not travel instantaneously.
This article provides elementary school teachers with background knowledge about science concepts needed to understand the first of seven essential principles of climate literacy--the sun is the primary source of energy for our climate system. Graphs, diagrams, and oneline resources provide more background for the teacher. The article appears in a free online magazine that focuses on the seven essential princples of the climate sciences.
The main objective of this video lesson is to bring the students' attention to the importance of basic and natural sciences in our lives. The lesson will introduce a topic (sustainable energy) that is related mainly to chemistry and is not usually covered directly in a high school curriculum. We hope that this lesson will show students how important and useful the natural and basic sciences are not only for our daily lives, but also for sustainable development. The lesson will present creative and challenging ideas on the topic of alternative energies. It is hoped that students will be inspired by the introduction of these ideas, and that they will develop the confidence to come up with creative ideas themselves. Background for this lesson is based on fundamental concepts in chemistry (mainly), biology, physics and environmental science.
The Take Action column in the free, online magazine Beyond Weather and the Water Cycle suggests actions young people (K-grade 5) can take to reduce the impacts of climate change. The magazine examines the recognized essential principles of climate literacy and the climate sciences as well as the guiding principle for informed climate decisions.
