Doppler effect, red shift, CMBR and Big Bang animated powerpoint

(5)
For use in a lesson on Doppler effect, red shift, CMBR and the Big Bang.<br /> Some suggestions for demo/practical and accompanying worksheet.<br /> <br /> Note: For the purposes of simplicity and continuity from the practical I have used emission spectra rather than absorption spectra to show the spectral lines from stars. This is adequate for GCSE classes but would be incorrect for A level.

Card spectroscope template (better than the CD ones!!!)

(2)
Template for a card spectroscope that uses 1000 line diffraction film.<br /> Better than CD ones as students can make quantitative measurements of wavelength.<br /> Useful for teaching spectroscopy, electromagnetic spectrum and red shift.
