Slow a sample of fast-moving atoms with a laser to capture them in a trap by setting the temperature of the oven and adjusting the strength of the magnets. Once trapped they can be cooled and used in a variety of experiments.
Notice how magazines print photos using dots made up of percentages of only three colors and black. Try your hand at using percentages of cyan, magenta and yellow to match the magazine color displayed.
Test your knowledge of atoms, orbitals, periods/groups, characteristics of families, isotopes and relative mass. Take this 39-question test, review your correct and incorrect answers, and print out your assessment.
You'll be challenged to test your reaction time under different conditions and then compare the results.
