This is an activity about using solar arrays to provide power to the space station. Learners will solve a scenario-based problem by calculating surface areas and determining the amount of power or electricity the solar arrays can create. This is... (View More)

This is a math-science integrated unit about spectrographs. Learners will find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, the students will build their... (View More)

Audience: High school

Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. The... (View More)

This interactive illustrates how images from space get to Earth and how we interpret the images. Users are encouraged to experiment with images to get a firm grasp of how scientists use color filters to interpret data. Click on the initial image at... (View More)
