Derek Owens sketches as he teaches image formation in a plane mirror. When you look at an image in a mirror, it appears as if it is behind the mirror. Mirrors create a virtual image as opposed to a real image. This educational resource...

What are the benefits of choosing a sunscreen with SPF 30 over one with SPF 50? Why is spray application not as effective as rubbing in lotion-type sunscreen? How does sunscreen affect the environment? An informative video on...

Chiton are mollusks that have no face, but have many eyes made from a component found in limestone. Here is a video that introduces nine ways animals see the world, including through rock eyes like chiton. Viewers learn about a vision...

We typically think of lasers adding heat energy, but lasers can be used for cooling, too! An episode of a physics playlist discusses the science of lasers. Learners watch how to place lasers to effectively slow subatomic particles.

Take the class over the rainbow. Pairs or small groups follow directions to create a spectrograph. The pupils measure the angles formed by the different colors of the spectrum along with calculating the lengths formed by the spectrum and...

How are the wavelength, frequency, and speed of a wave related? The instructor in the video explains the process of determining the frequency of a wave with a known speed and wavelength. The wave is then classified along the...

Turn to the dark side! Learners discover the facts about the matter you can't see and can't interact with, yet, it may make up 85 percent of the universe. The narrator explains what we know about dark matter, how it changes the behavior...

According to the video, astronomy is like a jigsaw puzzle with an infinite number of pieces. The video explains the history and invention of telescopes, how they work, refraction versus reflection, and the changing technology. It...

Things are not always as they appear. The morpho butterfly appears to have blue wings, but they don't contain a drop of blue pigment. Learners watch as the instructor explains the physics behind these amazing blue wings.

Is there really more than one black? Although your crayon box may tell you otherwise, some blacks are, well, blacker than others! Discover the cutting-edge technology at work to produce the blackest black possible with a video from the...

Sometimes the best discoveries happen by chance. Scientists did not plan to find gamma-ray bursts, but that doesn't make the revelation less important! A video lesson in the SciShow Space series discusses the discovery of gamma-ray...

Even the kindest friends can become selfish and tyrannical in Hans Christian Andersen's "The Snow Queen." Class members complete story-themed exercises in language arts, social studies, and even physical science.

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...

Here's a colorful resource about spectra. An intriguing lesson teaches pupils about diffraction grating and about absorption and emission spectra. They see how to represent spectra using line plots and try out this skill in a matching...

Young scholars observe continuous and bright line spectra through a simple, inexpensive spectroscope that is suitable for classroom use and work through typical student laboratory exercises.

Students investigate the concept of a shadow. They design a tool to create shadows for an experiment. They make observations and record the size and shape of shadows. The lesson contains background information for the teacher to deliver...

Learners explore the properties of electricity.  In this electricity lesson, students construct an electric game board circuit using their knowledge of a series electrical circuit. Learners develop game ideas based on current...

In this microscope worksheet, students complete a crossword puzzle given twenty three hints about the parts of a microscope, the magnification of a microscope and the types of microscopes.

In this measuring star temperatures, students find the temperature of a star using Planck's curve and the Wein Displacement law. Students also find the peak wavelengths for given stars using Planck's curve.

In this plasmasphere worksheet, students read about the dilute region of gases 10,000 kilometers above the Earth where atoms are ionized. Students use a photograph taken by the IMAGE EUV instrument to answer 3 questions about the...

In this stars activity, high schoolers read about the Spitzer space telescope and they solve 5 problems about the mass, size, and power of dust grains and interstellar mediums detected by the telescope.

In this energy and mass worksheet, students read about Einstein's formula, E=mc2 and they solve six problems. They convert from different energy units to different mass units using a given formula.

High schoolers read science article on auroras and create a class bingo game with the scientific terms.

For this factor worksheet, students practice doing factor conversions of time, length, speed, and weight. This worksheet has 12 word problems to solve.
