Learning a New Language: Age Matters

Learning a New Language: Age Matters | Science Fair Projects | STEM Projects
Do you want to know if adults can learn a new language faster than children? This science project will explore the differences in language acquisition between adults and children.


The hypothesis is that adults are able to acquire a second language more quickly than children.

Method & Materials

You will need to assemble 20 participants, 10 children and 10 adults, and have them listen to a language CD for 7 days. On the seventh day, they will take a test with 50 multiple-choice questions.
You will need a CD recording of a lesson in the foreign language, a CD player, a test paper, a quiet classroom, a clock, and an assistant.


The results showed that the adults scored higher in the test and were able to learn the second language more efficiently compared to the children. The hypothesis was proven to be true.

Why do this project?

This science project is interesting because it explores the differences in language acquisition between adults and children. It also shows that adults can benefit from learning a new language, regardless of age.

Also Consider

To improve the reliability and accuracy of the results, a larger sample of participants should be used. Another variation of the experiment is to have the adults and children stay for a period of time in a foreign country or with a family that speaks the foreign language.
