High schoolers solve five problems including finding the cross sectional area of two bodies, determining the swept out volume of a moving body, finding the average particle volume of a body and determining the collision time for a body.

In this time intervals instructional activity, students solve 8 problems where they determine the time gamma-ray bursts last, the time black hole micro-flares are emitted, the time coronal mass ejections travel and the days between lunar...

Students place events in sequence and assign relative times to each event. They gain an understanding of relative and numerical time and become familiar with the methods used by scientists to develop the Geologic Time Scale.

Students explore speed by calculating the average speed of several snowmobiles, and predicting which of them is the fastest. They watch a race to verify their calculations.

In this solar flares worksheet, students observe a sequence of figures of a solar flare observed in 2003 from the Ramaty High Energy Solar Spectroscopic Imager satellite. Students solve 6 problems including finding the scale of each...

In this comet tail disruption worksheet, students solve 7 problems using two images from NASA's STEREO satellite showing the breakup of the comet's tail. Students analyze the diagram and use the scale to solve the problems about time,...

Students identify Newton's Laws of Motion. They students explore Newton's Laws of Motion and apply the second law with a classroom activity. The videos will provide visual examples of the effects of gravity while riding on a roller coaster.

In this Saturn learning exercise, students use a photograph of a hexagon feature on Saturn to solve three problems. These include finding the time it takes for the jet stream to complete one circuit around the hexagon, to find the size...

In this sunspots worksheet, students observe two images taken by a solar observatory over a certain amount of time. Students determine the changes in the pictures and then calculate how fast and in what direction the particles are...

Students observe two demonstrations to conclude why bulge developed on the north flank of Mount St. Helens and conclude that when the "cap" was removed the pressure inside the volcano was suddenly released causing the violent eruption.

In this variables and expressions worksheet, students solve 7 problems using different mathematical formulae to find the length of Earth's day in the future, the distance to the galaxy Andromeda, the temperature of a gas cloud emitting...
