Does Highlighting Help Memory?

Does Highlighting Help Memory? | Science Fair Projects | STEM Projects
Have you ever wondered if highlighting what you read helps you remember more easily? In this science project, you'll find out if highlighting can help you remember better.


The hypothesis is that the participants will perform better in the tests when they highlighted their own essays.

Method & Materials

You will select 10 students aged 12 years old to take part in this experiment. You will give them each a copy of the essay to read for a period of 2 hours. After that, you will collect the essays and allow the participants a 30 minute break. Then, you will assemble the 10 students in the exam hall and give them the questions for the essay. They will be allowed 1 hour to complete the test.
You will need 3 essays of equal difficulty, 20 questions about each essay, model answers for the 3 essay questions, 10 students aged 12 years old each, a stopwatch, a quiet examination room, and 10 highlighters.


The results showed that the students who were asked to highlight what they read performed only slightly better in the test. The hypothesis that the participants will perform better in the test when they highlighted their own essays has not been conclusively proven to be correct.

Why do this project?

This science project is interesting because it tests the effects of highlighting on memory. It is also unique because it uses a variety of materials, such as highlighters, essays, and questions, to test the hypothesis.

Also Consider

Experiment variations include testing the effects of using different color highlighters on test results, or using participants of a different age group.
