Surveys the history of wind power and windmills, outlines the science that makes them work, and provides instructions for increasingly difficult projects that demonstrate each principle.
See how termites inspired a building that can cool itself
How do you cool a building without air conditioning? Using an approach called biomimicry, see how architect Mick Pearce harnessed the ingenuity of termites to design a natural cooling system for the largest commercial building in Zimbabwe.
Over the past several decades, our world has been warming at a faster rate than ever before. Winters are shorter. Sea levels have risen. Territories of predators and prey have shifted. To survive in this new environment, animals everywhere have had to adapt, or face extinction. ... A Warmer World offers young readers a clear-eyed look at the effects of climate change on animals around the world.
Iqbal learns that his school's upcoming science fair has the theme of sustainability, and comes up with the perfect idea for his entry: he'll design a stove that doesn't produce smoke! With help from his teacher, Iqbal learns all about solar energy cooking, which uses heat from the sun to cook --- ingenious! Has Iqbal found a way to win first prize in the science fair while providing cleaner air and better health for his family at the same time?

For the past few centuries, fossil fuels have generated most of our world's energy. But these fuels pollute the environment, and they will eventually run out. Today, scientists are developing cleaner and more sustainable sources of power.
Describes how global warming has made the Arctic's oil, gas, natural resources, and minerals more accessible and how competition between nations and corporate interests for control of the resources is endangering the Arctic's fragile ecosystems. -- Publisher's description.
How does huddling help penguins stay warm? | The Kid Should See This
Emperor penguins live in the coldest of cold climates on planet Earth, enduring wind chills that reach -60° Celsius (-76° Fahrenheit). Their black
KIT:Place an ice cube on each of these two identical looking black blocks at room temperature. One ice cube instantly begins to melt and is totally gone in about 90 seconds. The other ice cube shows no evidence of melting whatsoever. Great for showing the difference in heat conductivity in different materials.
KIT: With this kit, two insulated containers (called calrimeters), themometers and and aluminum transfer bars make it possible to study the transfer of heat from a substance in one calorimeter to a substance in the other, measuring the flow of heat as it is affected by different variables.
