Lesson 7 – Special relativity
Learning outcomes
After these lessons students will be able to:
 Demonstrate an understanding of situation where special relativity can occur.
 Demonstrate an understanding of the twin paradox and its implications for stellar travel.
 Demonstrate an understanding of time and length dilation.
Big ideas
 Special relativity is ‘special’ because it describes the experiences and properties of objects travelling only at very high speeds (~speed of light) e.g. particle accelerators.
 For objects travelling at normal speeds (<80% of C), the Newtonian laws of physics are quite precise.
Learning Sequence
Show all resources
Welcome students to this lesson and encourage several of the students to introduce themselves to the class.

Investigation – Teacher introduces key postulates of Special relativity which include increasing mass, decreasing length in direction of motion, and time dilation using hand drawn cartoon graphics on a white board and prepared green screen images. Resources

Investigation – Teacher uses animations to explore the twin paradox and time dilation. Resources

Collaboration – Teacher divides the students into breakout groups and students discuss a number of key ideas given to each group to explore. Resources

Discussion – Students report back their ideas and findings regarding the key research ideas discussed.
Home Learning

Students explore further insights into the twins paradox to consolidate their understanding. Resources

Students continue to work to improve their final presentations for week 8.
