High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.

Science is magic that works. Magical color-changing beads and a coffee can that follows voice commands are just two examples of magic tricks that rely on science. After completing a hands-on activity and an experiment investigating the...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

Fossil fuels are non-renewable resources and have become crucial to the livelihood of countless individuals. Young chemists investigate an alternative method of generating energy by performing a series of activities that lead to the...

Learners investigate the relationship between potential and kinetic energy. In this energy lesson students investigate the height a ball will bounce when dropped from various heights.

Middle schoolers explore energy. They discuss the types and uses of energy and research an assigned energy source. They create a "benefits versus potential environmental impacts" chart that lists energy sources and possible impacts. ...

Students compare and contrast a cell and a battery. In this physical science lesson, students explain how they create energy. They conduct an experiment to apply what they have learned in this lesson.

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

Let the good times roll as young thrill seekers build a roller coaster on school grounds. Future engineers design and build a roller coaster from flexible tubing. The roller coaster is for a marble, so there will be plenty of room to let...

Don't kick the resource to the curb; you'll definitely regret it. Future engineers devise a kicking machine that launches a ping-pong ball toward a target. They can use a pendulum, a rubber band, or both, depending on whether they want...

Everything scholars will need to know about universal gravitation in order to be prepared for the AP Physics exam. is provided in this fast-paced video. Test taking tips and common misconceptions are also addressed in the film.

Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

There's quite a bit in this physical science packet. First, how is heat transferred? Learners read a brief explanation of conduction, convection, and radiation before identifying common occurrences (with pictures) as one of the three....

What kind of pears do electricians eat? Amperes! Presentation begins with electric field vectors for various charge configurations and field strengths for both point charges and uniform fields. It continues with various surfaces,...

It's disturbing to think that one third of children born after the year 2000 will suffer from diabetes and perhaps be the first generation to live shorter lives than their parents! Too many youngsters are not eating properly and are not...

Students explore the drawings of Rube Goldberg to design and construct a simple machine. They discuss simple machines, and using various materials and toy parts, design and construct a "Rube Goldberg" style machine to ring a bell.

A colorful and comprehensive PowerPoint highlights this instructional activity on waves. Junior geophysicists pretend that they are hired to analyze seismic waves. A worksheet is provided to go along with an online article about how...

Quantum tunneling plays an important role in nuclear fusion, the energy source of the sun. This simulation explores tunneling, double wells, and covalent bonds by allowing individuals to manipulate potential and total energy to learn...

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...

Young scholars drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. In seeing how falling...

Students studykinetic energy, friction, drag and acceleration by relating it to the Winter Olympics.  In this physical properties lesson plan students create tracks and determine how the course conditions affect bobsled, luge...

Ninth graders create a model of a hydroelectric generator. In this physics instructional activity, 9th graders discuss how energy can be transformed from one form to another. They make a flow chart for different energy generating plants.

Students explain how conservation of energy applies to roller coasters. In this physics lesson, students construct their own coasters according to a specified criteria. They make modifications to their design when necessary. 

Students study the physics used to design today's roller coasters.  For this engineering lesson students complete several activities including designing their own roller coaster.
