Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Students examine how steamships operate. They describe the necessary energy conversions. They construct a model paddlewheel ship. They use rubber bands as examples of potential and kinetic energy as they unwind and set the models in motion.

Using a teacher-built wind tunnel constructed from a paper concrete tube form, a fan, and a balance, individuals determine the amount of drag their rocket design will experience in flight. Pupils make modifications to increase the...

Teams of six to eight players imagine that they are driving in a vehicle and collect balls that represent carbon dioxide emissions based on their different activities. "Greenhouse Gas Guzzler" cards tell teams how many balls to collect...

Students investigate and then build neurons in this lesson. They are examined as key parts of the brain and nervous system and seen as different from normal cells.

Students study Georg Ohm and how he changed mathematics with his law.  In this experimental evidence and stastics lesson students complete an experiment on the characteristics of Ohm's law. 

Students participate in an activity in which they observe a ball as it rolls down an incline into a cup. They take measurements and use equations that describe the concepts of mechanical energy, work and power, momentum, and friction. ...

Interactive lecture discusses internal resistance which provides help to learners in developing an accurate model.

Simulation demonstrating how a point charge, a dipole, or a quadrupole shows field vectors or voltage. Change the charge and see the electric field direction and magnitude, and then record the detector values using a built-in data...

An electrostatic simulation that moves beyond the two-dimensional representations a book may provide. Try this Gauss' Law model which shows the electric field and potential for cylindrical and spherical symmetry.

Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field. Create models of dipoles, capacitors, and...

Adjust the magnetic field in this simulation to see how the flow of electricity is affected.

Students learn how engineers design devices that use water to generate electricity by building model water turbines and measuring the resulting current produced in a motor. Students work through the engineering design process to build...

It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick-it can make electricity. Electricity can be generated...

Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood...
