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...

In 1820, Hans Christian Orstead discovered the link between electricity and magnetism, which allows us to measure current and voltage. The simulation allows scholars to observe the inner workings of an ammeter and voltmeter as they...

High voltage power lines deliver electricity to homes, but each home requires low voltage. How does the energy get converted so it can be used safely? Pupils explore alternating current and transformers through a simulation. They control...

Can you get the puck into the goal using only electric charges on the ice? Scholars experiment with electrostatic forces as they determine which charges pull the puck and which repel it. Multiple levels reinforce different related...

You'll be strangely drawn to this activity! Physical science pupils learn how compasses work in an interesting interactive. The content covers magnetic poles, Earth's magnetic field, and what would happen if Earth's poles swapped places.

Which sports drink provides the best pick-me-up after the big game or grueling workout? It may not be the one you'd think! Food science is the focus in a surprising lab activity. Pupils use colorimetry to determine the amount of protein,...

Does the charge on a particle affect its energy? Scholars first explore how the strength of a charge affect the potential energy. They observe the change in the electric fields as this potential energy changes.

Add a splash of color to your chemistry class! Science scholars discover the principles behind color through a wide variety of hands-on activities. Lessons include dyes, chromatography, and flame tests.

Is this the end of the world as we know it? Pupils prepare for a coronal mass ejection during a lesson plan from the K20 Center. The activity combines video and Internet research in a collaborative assignment that focuses on public...

Young scientists explore many different types of energy including light, heat, nuclear, sound, potential, and more. They match the types of energy and identify when energy transfers from one type to another.

Make works of art using a vintage yet effective etching strategy. The surface of a semiconductor chip has specific patterns formed through a process called etching. Through a lab investigation, young scholars recreate that process...

Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function...

Dive into the mystery of sound waves!  Scholars brainstorm questions about how sound travels and why different items make different sounds. They then conduct experiments to answer their questions.

Are your young physicists static-savvy? Test their skills using an engaging interactive from the Static Electricity series! Learners evaluate scenarios to determine how charges move between conductors and insulators, then identify...

Class members build a machine to demonstrate Lenz's law and help this scientific principle come to life. After building a ring fling machine, instructions for properly operating the machine and a few thought-provoking questions lead to...

The surface of the moon has an amazing tale to tell. Learn about the moon's story with a PowerPoint presentation that describes the unique features of the moon's surface as well as explains its movement in relation to Earth.

Light the way to a better understanding of UV radiation. After exploring how UV beads work, future engineers design investigations to answer questions about UV radiation. They then create and test prototypes of a device that detects UV...

Textbooks come in all shapes, sizes, and media these days. An electronic textbook resource offers Physics materials for an entire course. The text offers an explanation of physics topics as well as examples of calculations and reading...

Grab a partner and shed some light on light. A remote learning resource has scholars play a board game to answer trivia questions about light. They also read about how Einstein contributed to the understanding of light as both a wave and...

Hear from deep space. Pupils learn how satellites transfer information back to Earth. They learn about three different ways to modulate radio waves and how a satellite sends information with only 0s and 1s. Using sound, class members...

Take a stretch, but don't wave goodbye. An interesting resource provides everything needed to present an introductory lesson plan on waves. Teachers present a PowerPoint defining the types of waves and their characteristics. Pupils use a...

All you need is light. Groups use a reflectometer to find the reflectivity of specific chemical compounds. Learners compare the graphs of the reflectivity of the known compounds to Martian soil. Using the graph comparisons, scholars...

Use spectral knowledge to make discoveries on a distant moon. Small groups gather information from images of one of Saturn's moons. The moon orbits within the E-ring made up of mainly water ice. Using information about the composition of...

Transform the classroom with energy. Pupils learn about different types of energy and practice identifying the types in the first lesson plan of six in a solar versus wind energy unit. The class sees examples of how one type of energy...
