A problem from a chemistry textbook is posed on the screen. In this problem, ethanol is used to illustrate how much energy, in joules, is required to change a substance from a liquid to a gas. The boiling point of ethanol is given, and...

As an introduction to the concept of energy, this interesting and informative resource would be a terrific addition to a unit. Although there is quite a bit of information presented about kinetic energy, potential energy, and related...

Put empty milk jugs to good use. Scholars consider the characteristics they might change about a milk jug to improve light absorption. They design a passive solar water heater using the milk jug and then measure the temperature change in...

Scientists discovered the first law of thermodynamics 25 years after the second law of thermodynamics. The seemingly obvious discoveries sometimes confuse scientists while more complex challenges encourage extra study—and take more time...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

The fifth lesson in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.

Melting ice seems pretty easy, right? But what's actually happening is much more complex! Introduce the class to enthalpy calculations using a video tutorial. The narrator explains and performs the calculations that show the energy at...

When does potential energy become kinetic? Young physicists find the answer to this question as they view the video lesson. They learn the difference between the two energies and how to calculate their values. 

This brief video provides definitions for charge, current, and voltage and compares and contrasts these terms. The video also discusses coulomb, amps, and joules. 

Watt is this video about? It explains how to calculate power when you know the energy and time, and continues by discussing fuses, currents, and electrical surges. 

Work, energy, and their relationship to power: what is the common thread? Explore this with your class as they learn the concepts of work and energy, both kinetic and potential, before completing multiple practice problems to demonstrate...

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third instructional activity of the series, learners conduct an experiment, demonstrating the...

The eighth video in a series about basic physics terms, a segment focuses on work. A strong man and a clown demonstrate work in action. After several examples and a defintion, the video closes by introducing joules as a unit of measure.

On this physics handout, pupils read about the Hadron Collider used to make new sub-atomic particles by accelerating protons. They solve 6 math problems that include translating electron volts to Joules. This is geared toward high school...

In this specific heat worksheet, students solve 4 problems for either the specific heat of the substance, the amount of heat needed to raise the temperature of a substance a particular number of degrees or the amount of heat released in...

Showing a warming curve for an unknown substance, this worksheet asks for seven answers about particular points that have specific meaning.  The following seven questions require learners to calculate certain answers given supporting...

Teens often display potential energy in class and kinetic in the hallways. This third presentation covers the six types of energy, each in potential and kinetic form. It also covers the Law of Conservation of Energy and Einstein's Theory...

What would you be if you were attached to another object by an inclined plane wrapped helically around an axis? In this fourth presentation that covers work and simple machines, young physicists look at Newtons and Joules as well as...

An understanding of chemical reactions really boils down to two concepts: entropy and enthalpy. Follow along with this instructional video as it explains how these two principles are used to calculate Gibbs free-energy which...

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

Matter and the energy held by molecules is explained here. The information provided about the transfer of energy between substances and the resulting temperature change will be useful to your students.  They will be able to work through...

For this energy worksheet, students are given a table of the many measurements of energy. They solve 6 problems converting from one measurement of energy to another using the conversion factors given.

In this specific heat worksheet, learners read about the amount of heat needed to raise the temperature of a substance. They are given the equation for calculating joules and they solve four problems using the equation.
