Observing Latent Heat With a Portable Hand Warmer

Clever! Use a clip from the 1997 film, Volcano, to get your chemistry class knee-deep in heat concepts related to lava. In the movie scene, lava flow is stopped in the nick of time. Your class must use calculations to determine if this...

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time. It also...

Heat things up in your physical science class with this interactive lesson series on thermodynamics. Through a series of class demonstrations and experiments, young scientists learn how heat is transferred through conduction, convention,...

This is a must-have resource with everything you'll need for studying food safety with your pupils. From handwashing scorecards and cleaning kitchen surfaces to navigating the world of microbes and food-borne illnesses, here you'll...

I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and assessments....

When the chemists who designed hand warmers were working, they had to consider how much heat they could give off to keep people warm  — and not burn anyone in the process. How is this heat given off in a chemical reaction measured?...

Where does the heat come from in hand warmers? Learn about enthalpy, the change in energy in a system, to see that when chemical bonds are broken or formed, energy moves into and out of a system because of chemical reactions. 

Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...

Ladies and gentlemen, start your engines! Explore the cumbustion reactions driving the world's automobiles and the chemical solutions used to keep their engines cool with this fun instructional video.
