NIH Image Fault Investigation

How can a robot measure the length of something when we don't know how far the camera is from the object? The activity explains the concept of perspective and many others. Scholars apply this knowledge to judge the length of fish and the...

For this solar storms worksheet, students use a diagram given the location of two STEREO spacecraft satellites, a coronal mass ejection, the sun and the Earth to solve 2 problems about the coronal mass ejection. Students use segments,...

In this comet worksheet, students solve 3 problems using a composite image of the Temple 1 comet. Students determine the scale image, the size of the nucleus of the comet and the height of a cliff on the comet.

As part of a unit on the chemistry of the brain, thinkers learn how chemicals work to transmit messages between individual neurons and how controlled substances impact the synaptic cleft. They do so by playing a dice-and-card game in...

Camille Seaman's photoessay, "Witnessing Icebergs" documents just a tip of the problem of climate change through images of icebergs in both the Arctic and Antarctic polar regions. After viewing the haunting images, viewers respond...

If you've always wondered what JPEG means, now's your chance to figure it out. Scholars learn about file compression techniques, including the difference between lossless and lossy compression. The video explains run-length encoding and...

Students simulate life in space aboard the space shuttle. In this space exploration lesson, students work in small groups to model life aboard the space shuttle. Each student is given a job, conducts Internet research on space, and...

Students get a whole new perspective of the world through images obtained from the International Space Station. Students can even request images to be taken through ISS EarthKAM. Activities and educator guides are provided.

Students describe and interpret images. They make a simple sketch of an outcrop shown in a slide (or computer projection) then discuss possible interpretations.

Twelfth graders determine how scientists study the universe and particular astronomical objects using Internet research, images and NIH software. They work in groups to examine and use imaging software as they study astronomical objects.
