A website all about planetary mysteries—it's a one-stop-shop for all things, stars, planets, and space travel. Scholars read an astronomy overview to discover the page's big ideas, then choose from the plethora of resources, including...

Coordinate an attack on hungry gophers. Scholars play a game that relies on placing objects on the coordinate plane to stop gophers from eating a carrot. As the game levels increase, learners encounter different scales and the need to...

A 10-page interactive explains different facets of implicit bias, demonstrates how implicit bias works, and how people can counteract its effects. The interactive tools permit users to save their information in "My Work" folders, to take...

An interactive timeline uses images, videos, primary source documents, and links to informational text to chronicle the history of the Holocaust from 1933-1945.

Calling all science sleuths! A patient appears to have a disease eradicated years ago—how do you treat it? Scholars must research the illness, the possible causes, and find a cure before the disease spreads and wipes out the entire city....

A dozen years after a great plague wipes out the majority of Earth's civilization, a group of scientists joins together to fight infectious diseases. Scholars join the training mission and learn about viruses, bacteria, pathogens and...

Creating a solar system map is a snap thanks to a hands-on activity! Science scholars explore the solar system by building it wherever they choose during an interactive from PBS's Space series. Users pick both the location and scale for...

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...

An interactive resource covers all of the United States' most prominent and influential historic wars including the Vietnam War, the Cold War, the War of 1812, and the Korean War. Learners observe cause and effect as well as how violence...

The FDA approved more than 25 drugs to treat HIV—and often people must use them in combination. One of the largest challenges with these medications happens due to patient error. Class members use an interactive to learn about drug...

Filters provide amusing changes to images in applications other than just Instagram! High school pupils apply their knowledge of colored filters to three different interactive sets of puzzles. They identify light colors that pass through...

Objects contain pigments that selectively absorb a wavelength of light, and our eyes only observe a very small range of these wavelengths. Scholars apply these two facts to three different activities. They identify the pigment in an...

The dress color debate of 2015 taught the importance of understanding how we see light. Scholars view a shirt under two different colored lights and then must predict what color the shirt will appear under a third light. They apply color...

Light intensity varies by the strength of the light bulb as well as the distance to the light bulb. Pupils apply these concepts independently at first. They must solve for the light intensity as either the distance or the wattage of the...

Scholars relate each of the colors in the spectrum, except indigo, by comparing their frequencies, wavelengths, and energy levels. Then, they compare each section of the electromagnetic spectrum when considering the same three variables.

Scholars work through three different activities applying their knowledge of total internal reflection (TIR). First, they simply identify which diagrams create TIR and which don't. Next, they match different types of boundary behaviors...

Abraham Lincoln's face may only be worth one cent, but the online reading passage and questions about his life are an invaluable resource. Pupils read a passage about Lincoln's experience with the Illinois Legislature, earning his law...

Magnifying glasses and cameras often use converging lenses, but how do they alter an image? Pupils discover a lens, axis, and object arrow before identifying four characteristics of the resulting image. They label the location,...

Pupils apply their knowledge of refraction to four different sets of challenges. Each of the first three focus on one variable's impact on the direction of bending. The fourth combines variables for greater challenge.

We see curved mirrors every day in spoons, rear-view mirrors, stores as a safety measure, make-up mirrors, and in novelty stores. Scholars explore the changes to an image based on the curve of the mirror, the location of the image, and...

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....

Reflection seems simple to understand, but without a complete understanding, pupils struggle with ray diagrams, specular versus diffuse reflection, total internal reflection, and image formation. An engaging interactive provides three...

How did Abraham Lincoln begin to change the minds of American citizens? Join him in his quest with a reading passage about Lincoln's experiences as a congressman and public denouncement of slavery. The resource contains reading...

Learn more about Honest Abe with an informative passage that details his life chronologically. As learners read sections of the text, they answer multiple choice questions that draw on their ability to recall details from the passage.
