Believe it or not, steak, coffee beans, caramel, and toast have something in common. It's called The Maillard Reaction and it is the reason that things get browned when they are heated. It is a chemical reaction of sugars with amino acids. Dr. Kiki helps explain this process. Run time 03:38

Take a rock, add a whole bunch of heat and pressure, and presto! You have a new kind of rock: metamorphic rock. Metamorphic rocks can be formed from sedimentary, igneous, or even other metamorphic rocks. Find out more about metamorphic rocks with this slide show from StudyJams. Vibrant images are set to music with information written under each photo. A short, self-checking quiz and song are also included with this link.

Get help from an adult! The video gives step by step directions on how to make sidewalk chalk using Plaster of Paris, water, and powdered tempera paint. The instructor also explains the science behind the craft. Most kids think of solids turning to liquids and liquids to solids because of a temperature change. In this experiment, a chemical reaction causes the mixture to change from a liquid to a solid. As the chemical reaction occurs it also gives off heat which is called an exothermic reaction. This instructor makes a "holiday gift" with her sidewalk chalk, but this activity could be done any time of the year. (04:26).

People who live north of the equator are experiencing both higher summer temperatures and a greater frequency of extreme bouts of heat, according to a NASA statistical analysis of decades of Northern Hemisphere temperature data. A basic bell curve shows breakdown of these temperatures. Initially, the mean summer temperature for the Northern Hemisphere from 1951-1980 is centered at the top of the curve, with the frequency of cooler summers in blue and the frequency of warmer summers in red. Watch how the frequency of hotter temperatures increases as the visualization moves forward in time, showing how hotter summer temperatures are the new normal.

As the heat went out, the air pressure start pushing the water up. the beaker exploded because it had so much force, that it bounced on the table. Run time 03:59.

A focus on energy conservation brings the sciences to life in an art class at Redwood Middle School, in Napa, California. Sharon Campbell remembers sleeping out under the stars and watching Sputnik go overhead. Back then, she wanted to be the first astronaut. Instead, she became an educator. She has been teaching art now for twenty-one years at Redwood Middle School, in Napa, California, but she visits space on a regular basis, via a very special classroom.It began when Campbell won a grant from British Petroleum and went to Los Angeles for a workshop on energy conservation. She visited Southern California Edison, where she watched incoming energy switch throughout the state."It was during the heat wave, and I sat and watched California run out of electricity," she recalls. It was there she learned that power is a finite resource, and that if every homeowner installed just one energy-efficient light bulb, it would be enough to avoid a blackout for an entire year. "And that’s when the big bulb went off," she says.Campbell and her husband spent $14,000 of their own money to turn her classroom into the RMS Energy Star. Every summer and every Christmas, when her daughter Jacqueline comes to town, the family repaints the classroom. "I want it to be perfect, because my students deserve it," Campbell says. "They deserve to be in a beautiful place, to know that I want them to be here, and that the school values them." (05:54)

In this short video, students will learn about the vocabulary word "thermal". Thermal is defined as anything related to heat or an increase in temperature. Several examples of thermal heat are given (sun, cooking food, clothing, creating energy). This is a great resource when introducing the word thermal into the elementary classroom. (00:59)

This episode explores the concepts of regional versus contact metamorphism. Heat and pressure are discussed and their roles in changing various rock types into metamorphic rock varieties. Contact metamorphism is discussed and demonstrated using a torch and marshmallow, and regional metamorphism is discussed using lasagna and examples of metamorphic rocks. (3:47)

Mark Bishop explains how your heart works - and how to make it work harder. Diagrams show how your blood flows though the chambers of the heart in this animation. A great way to get students to understand how the heat works and how exercise helps the body. Some words may need an explanation so a handout would be good to add depth to this lesson. (02:42)

Neodymium magnet + copper pipe = magnetic damping:When a magnetic field moves through a conductor a current called an Eddy current is induced in the conductor due to the magnetic field’s movement. The flow of electrons in the conductor creates an opposing magnetic field to the magnet which results in damping of the magnet and causes heating inside of the conductor similar to heat buildup inside of power cords. The loss of energy used to heat up the conductor is equal to the loss of kinetic energy by the magnet.One note of caution if you decide to try this, these magnets are not for unsupervised children. In fact, everyone should be careful: Neodymium magnets larger than a half inch are very strong and should be handled with extreme care since they can be dangerous… It is best to stick with neodymium magnets of quarter inch diameter or less.

From DragonflyTV. Andrew and Alex live in Albuquerque, New Mexico, home of one of the biggest hot air balloon festivals anywhere. They are trying to determine how big a hot air balloon needs to be to lift things off the ground. Using the heat from a hot air gun, the boys try flying different sized plastic bags. The boys calculated the volume of the balloons by multiplying length x width x height and used an infrared thermometer to take the temperature inside our balloons. Since real hot air balloons carry weight, they also experimented with 3 different size tissue balloons to figure out how much each balloon could carry. The boys experimented with how many pennies each balloon could lift off the ground and then collected data and graphed the results. The video/experiment is a great example of predicting, estimating, and problem solving.

This video was made by the Energy Conservation for kids, Horizon Utilities Corporation, Hamilton, Ontario, Canada. Students will learn that it saves energy to use a toaster oven when heating up only a small portion of food instead of an oven. Students will also learn to run dishwasher only when full. This is a great resource to introduce students to what a difference they can make in their homes. This would work well in conjunction with non-fiction texts on energy conservation. (2:12)

In this video segment adapted from ZOOM, the cast tests two homemade solar cookers to determine which one can cook a "s'more" faster. Both designs exploit the fact that heat flows in three ways: by conduction, convection, and radiation. Though one cooker performs better than the other, they both outperform the experiment's control setup. Run time 03:12.
