If you are looking for a simple experiment idea that you can try at home, here is a quick short-term memory test. You can try this experiment on your own, but it would also be interesting to try with a small group of volunteer classmates. By seeing how many words you can memorize in a brief period of time, you can learn more about both the capacity and duration of short-term memory.
