Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

There's more to light than ROYGBIV! An enlightening laboratory investigation has learners explore the world of infrared light. When they use goggles that take away visible light, they experience how things look with only infrared light.

The color of the sky depends on the time of day. Young scholars experiment with scattering different wavelengths of light to recreate the color of the sky. They observe both the longer blue wavelengths and the shorter red and orange...

Clouds are nature's insulator! A lab investigation asks learners to use an infrared thermometer to measure differences in infrared temperatures. They find that pointing the thermometer at a cloud has a much different result than pointing...

Recycled Russian nuclear weapons provide 10 percent of the nuclear energy that the United States uses. The short presentation discusses the Teller-Ulam device. It provides a diagram of the parts as well as a description of the four...

The microwave is a staple in many American households, but how exactly does it work? Approach this question from a scientific and practical standpoint, and discover cooking strategies, recipes, and methodologies for the standard...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

Even magicians can't make energy disappear. In a discussion-based lesson, young scientists learn about energy forms and conversions. They see how energy is neither created nor destroyed; it just changes forms. This is the 11th...

These slides give sets of facts and trivia about gamma rays. Your physicists will learn the dynamics of scattering photons and energy involved in gamma ray bursters. The concepts are quite involved making this PowerPoint a nice addition...

Here is a physical science activity where pupils place thermometers inside of a white and a black paper pocket and place them under a lamp. They record and compare the temperature increase over a ten-minute period. Have your class...

A striking PowerPoint that presents the Yohkoh Telescope, some information about its construction, and the amazing x-ray images of the sun that have been captured. Specific information about the electromagnetic phenomena is given. This...

In this second of three lessons on power plants, future engineers find out how we generate electricity and how coal-powered plants operate. They work in small groups to make electromagnet generators to light LED bulbs. A set of...

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...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

The amount of energy Americans use doubles every 20 years. The first activity in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments at each in...

Looking for a quick way to supercharge your electricity and magnetism unit? Assign a very responsive interactive designed to illustrate the relationship between charge, electric field, and the resulting forces. Learners experiment with...

Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

Ready for a lab with a lot of razzle-dazzle? Young chemists observe flame tests of common salts through an always-popular activity. The updated resource focuses on observation skills, collaboration, and green chemistry practices.

Looking for a sun-sational multi-lesson plan full of videos, simulations, and discussion? Introduce your young scientists to all things solar with a four-part hands-on adventure. Pupils learn the basics of solar anatomy, space weather,...

Is light related to insulation? An informative hands-on STEM activity demonstrates how light affects temperature. First, the class investigates how light passes through different mediums and how that relates to temperature. Then,...

Students examine how changing magnetic fields induce currents in loops and coils, determine orientation and magnitude of magnetic field, describe Michael Faraday's experiments that led to conclusion that changing magnetic force induces...

In this atomic spectra worksheet, students answer eighteen questions about wavelengths of light, the emission spectrum, energy of photons, the frequency of electromagnetic radiation and electrons in the excited state.

Students explore communications by participating in a science class activity. In this communication technology lesson, students discuss the process of morse code, its history, and the electromagnets used to create the device. Students...

Learners work with a real optical spectrum of a gamma ray burst afterglow taken at the Keck Observatory. They measure the shifts of spectral lines, deduce the velocity of the astronomical object, and then use Hubble's Law to get its...
