Photosynthesis Investigation
Can scientists increase the rate of photosynthesis to help clean the air? Scholars complete an experiment determining net photosynthesis. Then, they apply knowledge from the activity to design their own investigations of the factors that...
Howard Hughes Medical Institute
Drug Adherence and Resistance
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...

Color Filters
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...
Physics Classroom
Color Pigments
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...
Physics Classroom
If This, Then That: Color
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...
Physics Classroom
Light Intensity
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...
Physics Classroom
Spectrum
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.
Physics Classroom
Total Internal Reflection
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...

The L.O.S.T. Art of Image Description - Converging Lenses
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,...
Physics Classroom
Law Enforcement - Refraction
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.
Physics Classroom
The L.O.S.T. Art of Image Description - Curved Mirrors
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...
