Students will be able to:
- Explain the significance of finding the brain's remembering mechanism.
- Participate in a memory study using written words and images.
National Science Education Standards
Science as Inquiry, Content Standard A, grades nine-12
High school students should know that scientists rely on technology to enhance the gathering and manipulation of data. New techniques and tools provide new evidence to guide inquiry and new methods to gather data, thereby contributing to the advance of science.
Principles and Standards for School Mathematics
Connections standard, grades nine-12
High school students should recognize and use connections among mathematical ideas, understand how mathematical ideas interconnect and build on one another to produce a coherent whole and recognize and apply mathematics in contexts outside of

CNNfyi.com article, "Making memories"
Blank note cards
One class period
1. Ask students to raise their hands if: 1) they know their address, 2) they remember the name of their second-grade teacher, and 3) they remember what they had for dinner last night. Lead a discussion about which was the easiest to remember and which was the most difficult to remember.
2. Have the students read the CNNfyi.com article "Making memories." Ask:
- What similar studies were conducted at Harvard and Stanford universities?
- Why is it significant that the part of the brain affecting memory is identified? How can advertising companies use this information to their advantage?
- What is Alzheimer's disease? How can this new research help people with Alzheimer's disease?
- Harvard neuroscientist Anthony Wagner used "magnetic resonance imaging," or MRI, machines to study memorization of words and pictures. He concluded that words or pictures that caused strong activity in the brain were remembered better. Why do you think this is so?
- Do you think personal experiences play a role in memory? Explain your answer.
3. Divide students into pairs. Have each student create 10 flash cards with random words and 10 flash cards with images from magazines.
4. Direct one student to show the note cards with the words to another student for 15 seconds. Time them and tell them when to change to the next card. Have the student who was shown the words recall all the words that they can. The partner should record how many they get correct. Repeat this procedure with the other person in the group.
5. Repeat the procedure using the note cards with images.
6. Have students calculate the percentage of the words they remembered and the percentage of the images they remembered. Students can calculate the percentage by dividing the total number remembered by the total number shown and multiplying by 100.
7. Ask students to find the average percentage for the class on word recall and image recall.
Have each student write a brief essay explaining which set of note cards he or she remembered best. Students should consider why they think that they remembered the set the best. Be sure to have students include whether they believe this is a fair test and explain why it is or is not.
Musical/rhythmic: Students can create rhythm patterns and see if their partner can repeat the pattern. If yes, they can continue to add to the pattern until the other student cannot remember it. Ask students to write down how many beats they were able to remember. Discuss these results and compare them to the tests done with visuals. Tally the class and see if some students have better memories for rhythm and some for visuals. Ask the class to draw conclusions about what their findings may say about individual students' learning strengths.
Students can create memory tests. They must give specific instructions as to what materials are used, length of time and procedures. Try the tests out on the class and discuss the results.
