Step 1. Open up to http://www-ed.fnal.gov/projects/labyrinth/index.shtml
Step 2. Select Warp Speed.
Step 3. Select Warp Speed and enter your name.
Step 4. Read the story and hit Warp Speed, then select Push the Particle.
Step 5. Select Go to Game.
Step 6. Read the next few screens.
Step 7. Turn the light bulb on in the mission.
Step 8. Select Show Data button and reset until you have the best score.
Step 9. Try to double score.
Step 10. Attempt to double your score after reading the passage and answering the following
question:
Before the particle enters the linac, it has an energy of 750 keV, or 750 kilo-electron
volts. (Kilo is a prefix that means 1000.) By the time it leaves the linac, physicists must
accelerate it to an energy of 116 MeV, or mega-electron volts. (Mega is a prefix for a
million.) How many times greater is the energy the particle has when it leaves the linac
than the amount of energy it has when it enters the linac?
About _ 1.5 _ 15 _ 150 _ 1500 _15000
Step 11. Select one of the above and hit All Done to see if you doubled your score.
Step 12. Print your Einstein bucks and hit Go Back.
