In this black holes worksheet, students use a formula for time dilation which causes delays in events that occur near the black hole. They solve 6 problems using the equation.

In this black hole worksheet, students use the equation for time dilation to solve 8 problems including determining the time it takes to receive a GPS signal from space, the time delay for the GPS-Earth system, the distance a radio...

Give pupils a magnifier, a mirror, and a flashlight so that they can examine their own pupils. As they shine a light on their eyes, the light is shone on how this structure dilates and contracts to control how much is allowed into the...

In this P and S waves instructional activity, students use a Slinky to simulate P and S waves showing compressional and dilational motion.

What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...

In this black hole worksheet, learners read about how images fade to black when they reach an event horizon of a black hole. Students solve 3 problems about black holes using a given equation for luminosity. They find the time it takes...

Students calculate distance, velocity, acceleration and time on their fantasy trip to the black hold. They apply Newton's Laws of Motion and calculate circular motion. They discuss any questions that may arise.

Learners read first hand accounts of earthquake survivors in order to begin the describe the different types of earthquake waves and the order in which they arrive. They engage in using earthquake waves as a means to indirectly study the...

Using an example of light bouncing back and forth between two mirrors in a rocket, time dilation is explained in this resource. Step-by-step calculations using Einstein's time dilation equation are shown.

Here's a solved problem in time dilation. It's still not easy to follow, but it's doable. The math is not difficult, but the mathematical thinking is demanding.

Time travel is a staple of science fiction stories, but is it actually possible? Colin Stuart imagines where (or, when) this fascinating phenomenon, time dilation, may one day take us. [5:04]

A decent explanation of the concept of time as the fourth dimension. The author discusses Einstein's theory of special relativity and the idea of space-time.

If the speed of light remains a constant then time and distance change. Oh, it can be confusing! This text will help clear up the confusion. Discussion questions should serve to reinforce comprehension.and exercises

This model permits manipulation of variables in order to observe the effects of time dilation on twin objects, one moving and one not, as shown in a spacetime diagram.

A good mathematical account of what happens to time as you approach c: the speed of light. Also provides a rather a fascinating video (fly through the Lattice) - don't miss it. Take some time and explore this site.

College-level electrical physics course highlighting Einstein's Special Theory of Relativity. Course introduces the physics of Lorentz contraction, time dilation, the "twin paradox", and E=mc2. Course features suggested readings,...

Einstein Light highlights the Theory of Special Relativity and related topics. Learn how Galileo, Maxwell, and Einstein contributed to our knowledge of relativity, electricity, magnetism, and time by watching fun, interactive modules.

This site from Stanford University is on the topic of simultaneity in relativity.

Click "Relativity Q & A". Over 200 questions and answers dealing with relativity (special and general), answered by NASA scientist Dr. Sten Odenwald. Answers are generally one paragraph, very clear and coherent.

Review your understanding of relativity with this study guide.

Short and sweet definition and explanation of hyperons in the particle zoo. Nice info about time dilation making hyperon beams useful.

This page provides an incredibly detailed description of Albert Einstein's Special Theory of Relativity. Definitely an excellent website with great pictures and examples!

Students observe and test their reflexes, including the (involuntary) pupillary response and (voluntary) reaction times using their dominant and non-dominant hands, as a way to further explore how reflexes occur in humans. They gain...
