Fun science demonstration you can do at home. Put an egg in a bottle that does not belong there. As the heat within the bottle causes the gasses to expand, once cooled, the gasses contract allowing the atmosphere to push the egg into the bottle.

In this short video, students will learn about the vocabulary word "insulator". Insulator is defined as 1. something that isolates or protects something else and 2. something that prevents electricity, heat or sound from escaping. Good examples are given (coat, coffee mug, feathers, fur, wall insulation, and wire). This is a good resource to help upper elementary and middle school students understand this concept. (01:01)

A rooftop farm in Brooklyn grows vegetables and doubles as a green roof, insulating the warehouse below. Green roofs save money on cooling and heating costs and also retain water, reducing the load on sewer systems. Annie Novak, head farmer and co-founder of Eagle Street Rooftop Farm gives us a tour and Lisa Goode, whose company installed the roof, talks about the process. (2:14)

In this Pick of the Week video, teenage students will be introduced to "Holes" by Louis Sachar. Summary--Stanley Yelnats is having a miserable summer at Camp Green Lake. Reason #1: Camp Green Lake is not a camp, it's a juvenile detention facility. For teenage criminal offenders. Which Stanley is not. Reason #2: There is no lake at Camp Green Lake. There's only desert. And blistering, unrelenting heat. Reason #3: Camp Green Lake is run by a crazy warden, who has a nefarious agenda of her own. Will Stanley survive his sentence and live to tell about it? Or will the poisonous warden and her desert of doom claim him first? This is a great resource to entice and encourage upper grade readers.

An extreme heat wave is gripping much of Europe, breaking records and causing widespread misery. Temperatures soared well over 100 degrees Fahrenheit in France, Germany and Spain. While the heat is coming from sub-Saharan Africa, some researchers say climate change is exacerbating and prolonging it. They warn more record highs are likely--and along with them, more deaths. William Brangham reports. (04.02)

A nuclear reactor creates energy by producing heat that, in
turn, heats water and produces steam to drive turbines and rotate
electrical generators. Find out how nuclear energy is used to bring
electricity to homes with information from a science teacher in this

The Northern Hemisphere over the past 30 years has seen an increase in the amount of land area experiencing what NASA scientists define as "extremely hot" summer temperatures, according to a new analysis led by James Hansen at the NASA Goddard Institute for Space Studies. These regions of "extremely hot" temperatures are shown on the map as brown.
Hansen and colleagues looked at statistics and linked this increase in extreme heat waves to climate change.
These "extremely hot" temperatures covered less than 1 percent of the Northern Hemisphere land surface during the time period 1951 to 1980. Since 2006 these extreme temperatures have covered about 10 percent of this land area.
The visualization shows how temperatures by region differed from the 1951-1980 seasonal average for June, July and August. White areas are considered "normal" temperatures, while blues and purples represent colder than usual temperatures. The range of hotter than normal temperatures is defined by the scientists as "hot" (orange), "very hot" (red) and "extremely hot" (brown). (00:31)

Every year on the island of Cuba, female land crabs migrate from their forest home to the coastline in order to release their eggs into the Caribbean Sea. This video segment from Nature highlights the many obstacles the crabs have to overcome in order to complete this annual journey. They must protect themselves from dehydration in the Caribbean heat, as well as traffic while crossing busy roads and highways. The crabs have an instinctive ability to trace changing tidal patterns of the sea and manage to reach their final destination. They never stop; no matter what the adversity, an invisible drive compels them to the sea to spawn. (4:09)

Explore the ways scientists use technology to see infrared light, including the ways we sense infrared radiation as heat and use space-based sensors to map conditions and changes on Earth’s surface. This video from NASA introduces and explains the concept of Earth’s radiation budget and the possibilities and consequences of it being out of balance. The video also describes the use of infrared sensing in astronomy. (05:22)

The high-speed winds of jet streams, found near the top of the troposphere, play a major role in guiding weather systems. Many factors, including Earth's rotation and the Sun's uneven heating of Earth's surface, contribute to the formation of the powerful eastward flows of the jet streams. In this interactive resource from NOVA Online, learn about the factors that create these powerful meteorological forces.

Want to learn more about the topic in this video? Here are some key words/phrases to get your googling started: - Radiation balance - incoming radiant energy from the sun minus outgoing energy heading into space. - Infrared radiation - electromagnetic radiation that is invisible to us; comes in longer wavelengths than visible light and provides energy transfer we call heat. (03:08) Thanks to Kurz Gesagt for illustrating this video! And for composing the music!

This interactive game contains three levels. In the first level, students choose the object which uses electricity to create light, heat, or sound. In the second level, students choose the correct type of battery for different objects. In the third level, students choose the item needed to make a circuit complete such as a source of power or type of wire. ( This link is for an interactive game and may take a few minutes to load.)

Reducing methane emissions is crucial to fighting climate change. The invisible gas traps over 80 times more heat than carbon dioxide—and we're emitting more than we thought. (08:01)
The greatest potential for methane reduction lies with fossil fuels, and solutions are readily available. So what's getting in the way?
