Some people can remember things almost effortlessly, while others struggle to keep in mind the most basic things. In this science experiment we are going test the memory of your friends and family. The optimum number of people to test is between 5 to 10. So make a list of all the people whom you can get to participate.

Next make a random sequence of all number from 0 to 9. Note it down. Then repeat this step till you have 10 random number sequences with you. Write down or print out each number sequence to an index card. On the back of the first index card write 1, the second write 2 and so on.   You will now have 10 index cards with a random string of numbers on them.

These will be used to test your volunteer’s memory. Give the friend the first card to read and memorize. Repeat with all ten cards. Now read back a string of numbers from a particular card and ask him which number index card it was written on. Go through all the index cards in random order and mark the right or wrong answers given by your friend.

After you have the answers of your friend you can calculate the percentage of how often he was right. The higher the percentage the better his memory. Repeat this science experiment with all your other volunteers. You can change the test by asking them to recite the number string on a particular index card to make it tougher.
