Avoiding heat stroke during the summer may seem like a breeze, but it can creep up when you least expect it. Keeping cool is the key. Dr. Margaret Harris, a family health doctor, walks you through some signs of heat stroke as well as tips for dealing with someone that is suffering in the summer heat. Some signs of heat stroke include the following: no sweating, hot and dry skin, increase in body temperature, confusion, fainting, irritability, headache, etc. This informative video gives tips for dealing with a person who is having heat stroke symptoms. Content is appropriate for adults and is beneficial for anyone who spends time outside during summer. (01:21)

A machine's energy output cannot be greater than its input. In this session, look at the energy that goes into useful work, examine how some always ends up as heat, and see why systems are never 100% efficient.

What makes the liquid in a thermometer rise or fall in response to temperature? Which contains more heat—a boiling teakettle or a swimming pool of lukewarm water? In this session, we focus on the difference between heat and temperature and examine how both are defined in terms of particles. We also use the particle model to explain a number of everyday phenomena, from why things expand when they are heated to the role that temperature plays in changes of state.

Heat is thermal energy that exists in matter. The faster an object's particles move, the more heat it has. Heat can be added to an object by making its particles speed up. There are three basic forms of heat. Learn more about heat with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.

In this video, Mr. Edmonds sings about the differences in heat and temperature. Heat and Temperature are related but they are not the same. Temperature is not energy, but it is a measure of the kinetic energy of particles. Heat is measured in joules and may be potential or kinetic energy. If it is used as latent heat of fusion or vaporization, then it is potential. If it is used to raise temperature, then it is kinetic. Some of the key vocabulary words include the following: heat, joules, kinetic energy, potential energy, and matter. This is a fun resource to use to help your students master this important skill. Middle School and High School students will enjoy this catchy tune. (4:08)

This 5:25 long video shows how friction always creates heat in race cars. Brakes and tires depend on friction to work, but more friction isn't always better. In the engine, friction is never good and engine builders use everything from oil to high-tech coatings to get a little extra horsepower. A good lesson to show students how friction impact their life.

When a laptop computer overheats, it can possibly turn off without any notice, causing lost information; it can also cause the processor memory to pop out and turn off. Allow a laptop room to vent heat from the battery by using a cooling unit attached to the bottom of the computer. English captions. (3:00)
