Did you know the same battery we use today was invented in 1887? With only minor upgrade, the ‘dry cell’ battery was a scientific victory because they were liquid free and could be used in portable devices. But how do batteries work? Learn More
Every year, the world uses 35 billion barrels of oil. This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables?

High school science teacher Tyler DeWitt was ecstatic about his new lesson plan on bacteria (how cool!) — and devastated when his students hated it. The problem was the textbook: it was impossible to understand. He delivers a rousing call for science teachers to ditch the jargon and extreme precision, and instead make science sing through stories and demonstrations. Learn More

Science in the Classroom (SitC) is a collection of freely available annotated research papers from that aim to help educators, and high school students understand the research contained in scientific primary literature by using annotations and providing accompanying teaching materials. Annotations include vocabulary, methods, descriptions of prior research, and explanations of major conclusions. Each paper has an educator’s guide outlining connections to science competencies within STEM learning frameworks and standards. Educator guides also provide suggested activities, discussion questions, and resources for further exploration of the subject.

Deep underground lie stores of once-inaccessible natural gas. There’s a technology, called hydraulic fracturing, or “fracking,” that can extract this natural gas, potentially powering us for decades to come. So how does fracking work and why is it a source of such heated controversy?

For the microscopic lab worm, life equates to just a few short weeks on Earth. The bowhead whale, on the other hand, can live over two hundred years. Why are these lifespans so different? And what does it really mean to ‘age’ anyway? Joao Pedro de Magalhaes explains why the pace of aging varies greatly across animals. View full lesson »
This interactive tool allows you to create your own global energy scenario within technologically feasible approaches. This is a “waving a magic wand” exercise in that you will be able to alter the present world energy system instantly rather than a realistic projection over time.
In four steps, you’ll 1) get familiar with the current energy system, 2) explore opportunities for efficiency improvements, 3) experiment with greater electrification of the energy system, and 4) choose energy sources and their amount. Start Exploring
