Middle School Chemistry: Heat, Temperature, and Conduction

Physical science scholars discover an array of heat sources. They experiment to connect radiation to heat. They begin to understand thermal equilibrium. Then, they test to see if mass affects the rate of temperature change. Choose a few,...

Explore thermal energy with this short episode. Jiggling molecules and hand-drawn animation help to explain that just because something has a lot of thermal energy, it doesn't necessarily feel hot to the touch. This is an ideal addition...

Explore heat, temperature, and the conduction of thermal energy through different materials.

Based on experimental observations, students describe, on the molecular level, why the liquid in a thermometer goes up when it is heated and down when it is cooled.

Three experiments are shown to demonstrate thermal conductivity. Dr. Carlson is amusing and educational at the same time. Show this video in your chemistry class when teaching about heat conductivity, especially if you do not have the...

From the Physics 2000 site, this page exemplifies their usual superb discussion of the concepts of heat, temperature, and absolute zero. Using an entertaining series of cartoon characters, the page gives a very understandable discussion...

Investigate why a charged object is attracted or repelled by another charged object. Explore the concept that the attraction between positive protons and negative electrons holds an atom together.

Students see a demonstration of a color change using universal pH indicator and then change the concentrations of an acid and a base using a universal indicator to test the pH of the resulting solutions. Through an animation, they see...

This lesson begins with a story about rescuing reptile eggs from a new construction site. Using the story as motivation, students are presented with an engineering design challenge: Build a portable device which can warm, support, and...

Students observe, on a molecular level, how heating and cooling affect molecular motion.
