Scientific Method Experiment

**Topic:** boys or girls and memory
 * Question:** Do boys have a better memory or do girls have a better memory?


 * Background Information:** According to http://www.madsci.org/posts/archives/1996-12/851983420.Ns.r.html, it depends on the memory of a boy or a girl. The growth starts when they are a baby. During the development his or her brain will be affected by how many hormones are present. This will decided weather the baby will be a boy or girl. Some people believe that girl's have more connection in their brains then boys do. Girls are dominate with their right hemisphere of the brain while boys are dominate with the left hemisphere. We can not say that boys or girls have a better memory.

According to http://members.tripod.com/z_adams0/, boys tend to have a better short term memory then girls. They can remember reading maps, sense of direction, and some action shown and many more. While girls tend to have a better long term memory then boys. They can remember Anniversary dates, birthdays, or any other long term memory.

According to http://findarticles.com/p/articles/mi_m2294/is_2002_Dec/ai_98125314, girls have a better verbal episodic memory then boys. Girls are also better at autobiographical memory. Girls can basically remember important events that are verbal and about certain people. Girls also remember childhood memories better then boys. This is because girls have better long term memory then girls, girls have better short term memories


 * Hypothesis:** If I give 5 boys and 5 girls a test on memory, I know that girls have a better memory then boys, because girls have a better long-term memory so their short term memory should be averaged out enough that they can remember images,words, or anything else.


 * Materials:** You need for materials...
 * Paper
 * A pencil
 * Words
 * numbers
 * notebook
 * pictures
 * The Procedure:** The procedure is...
 * 1) type out some words and numbers on a sheet of paper.
 * 2) *optional* find some pictures with a o.k amount of detail.
 * 3) create a graph used to record your data.
 * 4) find 5 boys and 5 girls to take the test.
 * 5) Give each person a short term test and a long term test
 * 6) For short term, give them a test where they must look at some letters or words, then ask them to read different letters or numbers out loud, then try to say the previous letters and numbers without mess ups.
 * 7) For long term, give a word test where they have to memorize a word or a number sequence, and one hour later or longer, ask them the word or number sequence.
 * 8) record all data.
 * 9) average out the data and see who has a better memory for short term and long term. Boys or girls.


 * The Experiment:** Do the experiment


 * Data**: This graph shows how many numbers out of the number combination they got correct.

Conclusion: In my hypothesis I said, If I give 5 boys and 5 girls a test on memory, I know that girls have a better memory then boys, because girls have a better long-term memory so their short term memory should be averaged out enough that they can remember images,words, or anything else, I was wrong. Boys, by 2 points, have a better memory then girls. This may be because boys do different things to remember the number combination. Some boys used their fingure to draw out the numbers, or looked at the keyboard. All the girls just tried to remember from their head. What I could have done better was gotten a lot more people, and a lot harder tests. I should have given the boys and girls a long term memory test and a short term memory test.
