In this energy, work and power learning exercise, learners solve 12 problems about circuits, electric motors, Ohm's Law and electric currents.

Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

How can heat power an engine? Scholars observe a heat engine working and control variables to determine the most efficient setup. They change the amount of heat input as well as the stroke length. Energy efficiency numbers prove the...

The camera flash works based on a simple circuit, but why does it require a capacitor? Scholars work through two levels of simulations related to circuits and capacitors. The pupils first use a simple circuit with a battery,...

While only briefly mentioned in most Physics books, plane mirrors and their applications offer the basics necessary for future studies. While working through an interactive, pupils demonstrate knowledge of both reflection and its forms....

Are you feeling weighed down by your current gravitation presentation? Assign a hands-on interactive instead! Physics scholars work through a series of progressively harder questions about mass, distance, and gravity using an online...

What can your class tell about a wave just by looking at it? Using a simulation, physics pupils work through a series of case studies to determine the effects of speed, frequency, and density on waves. Part of a larger playlist on waves...

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

How do contact lenses work? The simulation allows young scientists to explore focal length and lens type to see how and why contact lenses work. Pupils control the focal length for an eye and a lens, the type of lens, and the distance...

Tommy is trapped on an ice bridge and needs you to balance the charges so he doesn't fall into the icy water! Scholars apply Coulomb's Law, which relates to both the strength and the distance between charges. They work with these two...

Swimmers improve their times by understanding the physics of their sport. As a swimmer moves through the water, the efficiency of motion affects the resulting velocity. Through an interactive simulation, pupils change the level of motion...

Here's a force to be reckoned with in the physics classroom! Scholars discover the movements associated with tension, compression, and other common forces through a hands-on simulation. Pupils pull, push, and twist their way through each...

Physics class has its ups and downs ... especially when it involves energy concepts! Scholars analyze information to determine changes in kinetic and potential energy using an interactive resource. Realistic scenarios make connecting...

Long before the civil rights movement, leaders were working to secure equal rights. An informative activity explains the 1922 anti-lynching campaign with a map. Scholars analyze the map, complete a worksheet, and participate in group...

In this matter exam, high schoolers answer 80 multiple-choice and short-answer questions on atomic structure, atomic bonds, and equations related to energy spectra. A scientific calculator is recommended. A student's answer sheet and an...

Physics class sure can have its ups and downs! The first in a series of seven interactives from the Waves and Sound series introduces young learners to the concept of wavelength. Scholars work through the interactive to discover the...

All together now! Physical science pupils observe the effects of temperature and amount of substance on pressure and volume of a gas. The interactive resource guides learners through the Combined Gas Law, where they observe changing...

How are charge, distance, and force related in electrostatics? Science scholars ponder the outcomes of changing variables using an interactive resource from the Static Electricity series. Individuals practice using Coulomb's Law as they...

Pupils focus on the flow of electricity as they work through three sections of questions as part of a series of lessons on electric circuits. The activities cover the fundamentals, case studies, and law breakers. Learners use conceptual...

Physics formulas provide more interest than simple math equations thanks to an informative installment from the series on Newton's laws of motion. The formulas guide pupils' thinking about how varying a quantity affects the rest of the...

Roy John Britten easily earned a PhD in nuclear physics—but he found painting with water colors too difficult. Young scientists learn about Britten's life, career, and research with an online interactive. They read a biography, view...

In this mammals worksheet, students compare and contrast the physical characteristics of bats and people by filling out a chart. Students complete 17 rows in the chart and answer 3 short answer questions.

Most pupils don't know what a telegraph is, much less how one works. A secret simulation has scholars pick the size of the primary and secondary loops, the battery voltage, and which letters in the Morse Code they want to transmit. They...

What forces are at work when playing tetherball? Using a simulator, pupils control the ball mass, tether length, and ball speed to better understand the physics of the game. A worksheet and challenge questions reinforce the concepts...
