Memory Chunking

Memory Chunking | Science Fair Projects | STEM Projects
Have you ever noticed that most telephone numbers are seven digits long? That's because research shows that for most people, seven digits is the most they can remember the first time they hear a phone number. But can you remember more if the information is grouped together?


The hypothesis is that people can remember more information if it is grouped together.

Method & Materials

You will test 10 participants by presenting them with two poster boards. The first poster board will show random symbols, and the second poster board will show the symbols grouped together. You will ask the participants to memorize the symbols for 30 seconds, then ask them to repeat back as many symbols as they can remember.
You will need 10 participants, two poster boards, a marker, a watch with a second hand, and a data table.


The results showed that the participants were able to remember more symbols when they were grouped together. This suggests that chunking can be an effective way of providing context to information so that it can more easily be retained and retrieved from memory.

Why do this project?

This science project is interesting because it demonstrates how chunking can be used to help people remember more information.

Also Consider

Variations of this experiment could include testing different age groups or testing different lengths of time for memorizing the symbols.
