3 Question 1 We can see the Ultraviolet part of the electromagnetic spectrum: TrueFalse

4 Well done! End

5 No, sorry……… You need to revise the electromagnetic spectrum. With this link, please remember that often, the electromagnetic spectrum is pictured with the high energy waves (e.g. gamma rays) on the right hand side.With this link, please remember that often, the electromagnetic spectrum is pictured with the high energy waves (e.g. gamma rays) on the right hand side.

6 Question 2: which of the people is the most likely to burn quickest when out on a sunny day? Click on the correct face.

16 No, sorry… Watch this animation to get the correct answer.Watch this animation to get the correct answer.

17 Question 6: In order for infrared radiation to be detected, it must be: absorbed reflected

18 No sorry….. See the animation on page 11 of the following link: physics/pc/lessons/uk_ks4_waves_2/h- frame-ie.htmhttp://lgfl.skoool.co.uk/content/keystage4/ physics/pc/lessons/uk_ks4_waves_2/h- frame-ie.htm

19 Question 7: Which of the following types of radiation is ionising? Visible light Infrared Ultraviolet Microwave

20 No, sorry… You need to learn about ionising and heating radiation, and which types they include. Go to: science/21c/radiation/electromagneticradi ationrev6.shtml

21 Question 8: Which type of radiation do mobile phones use to communicate with the base station? 1.InfraredInfrared 2.MicrowaveMicrowave 3.GammaGamma 4.UltravioletUltraviolet

22 No, sorry… Go to science/21c/radiation/hazardsradiationre v3.shtml

23 Question 9: Is microwave radiation ionising? 1.YesYes 2.NoNo

24 No, sorry…. You need to learn which types of radiation are ionising. Go to science/21c/radiation/electromagneticradi ationrev6.shtml

25 Question 10: Are x-rays ionising? 1.YesYes 2.NoNo

26 No, sorry… Go to science/21c/radiation/electromagneticradi ationrev6.shtml

27 Question 11: If we didn’t have an atmosphere, what would happen to the temperatures of our planet? 1.They would get hotterThey would get hotter 2.They would get colderThey would get colder 3.They would fluctuate to greater extremesThey would fluctuate to greater extremes

28 No, sorry… 1.To get the correct answer, compare it to Mars, which doesn’t have an atmosphere like ours (click on the solar system button): _preload.html

29 Question 12: Which of these three things does not increase the CO 2 levels in our atmosphere? Driving cars that use fossil fuels Factories Photosynthesis Respiration

30 No, sorry… You need to learn about the carbon cycle. Please go to: timedia/uploads/alberta/CarbonCycle.htm l

31 Well done! If you got them all right first time, that’s great! Otherwise, please click on this button to take the test again, but this time try to get them all right, now you’ve done some revision.
