Relativity (time dilation) Workbook

(0)
This Excel workbook can be given to students to work through. It is designed and aimed at A-Level students to work through themselves. All the information about relativity, how it works, why it works and about Rossi's original work is on there. The activities are computer and math based and are interactive so help students through calculating dilated time, muon count etc. The workbook also incorporates excel formulae so, if you want to give your students a challenge to be able to ask excel to do math equations, they can and are shown how to. If not, cells accept calculated numbers. The whole thing is intuitive and explanatory, just give it to them and let them go!
Refraction Investigation Animation

Refraction Investigation Animation

(1)
PowerPoint contains two slides. First slide is a step-by-step instruction / overview of how to conduct the experiment (refraction through a rectangular block). Second slide is the same as the first but on a loop. With lower ability groups I keep the second slide with the entire investigation procedure on the board in a loop so they can watch it if they forget what to do (good differentiation). Slide also shows how to use a protractor to measure angles for students. At the end of the first slide, click “Slide 8” to play the loop. Text / instruction boxes can be edited in terms of colour, text etc to suit and will still animate. If you need any help or have an addition you want to suggest, get in touch!
