Read about all the jobs astronauts do and all the responsibilities they have while on a spacewalk. After reading the what, the why, and the how about spacewalks, readers respond to six comprehension questions.

Hold your breath. The video and interactive website introduce the class to spacewalking and spacesuits. Using oxygen data from two astronauts, individuals determine a mathematical model to fit the data. Using that mathematical model, the...

If he keeps this up, will he have enough air? After watching a video about spacewalks, groups of four brainstorm aspects of spacesuit design and present it to the rest of the class. Groups create mathematical models of oxygen use for two...

Pupils work together to investigate the cooling of NASA’s Neutral Buoyancy Laboratory. Using data collected as the pool cooled, groups determine the values needed in Newton's Law of Cooling equation to model the situation. They...

That is a lot of water. Class groups explore the size of the NASA's Neutral Buoyancy Pool and calculate the volume of water needed to fill it. They then compare that volume to the amount of water needed to fill a pool the size of a...

Who was the first person in space? What was the name of the first animal in space? These fun and intriguing questions get answered with a presentation covering the beginnings of space travel. There are eight informational slides that...

Imagine the challenge of getting the space shuttle to rendezvous with the International Space Station. Groups must determine the elliptical transfer orbit needed to get the space shuttle from its orbit to the orbit of the International...

How long does it take spacecraft go around the earth? Using the circular orbits of the space shuttle and the International Space Station, groups determine the distance traveled in one revolution, then calculate the distance traveled...

How do you model the movement of an astronaut? The activity features software that uses an avatar to mimic movement. Groups work to determine the translation between the pre-image and the image. They then experiment with reflections in...

Working as teams, class members try to rescue an astronaut using the shuttle arm on a TI-Nspire simulation. Teams must determine the different angle measures in order to reach the stranded astronaut. 

Students investigate the Hubble telescope's role in astrophysics research. They complete a Webquest, watch a video, view Hubble photographs, play online games, answer discussion questions, and evaluate newspaper articles about optics.

In this using infinitives in context worksheet, students read an article containing infinitives, then interactively complete 8 sentences with immediate online feedback.

Students use cross-multiplication to find the unknown respiration rate of an astronaut. In this multiplication lesson plan, students also use the same process to find missing values in proportions.
