Do adults pick up a new language faster than younger learners? You gather 10 participants aged 10 to 15 and 10 adults aged 25 to 40. Both groups listen to the same foreign language CD for two hours a day over seven days.
On day seven, everyone takes a 50-question vocabulary test. The adults score significantly higher than the younger group. Their average correct answers nearly double those of the younger participants.
Hypothesis
The hypothesis is that adults are able to acquire a second language more quickly than children.
Cognitive development does not stop in childhood — the brain continues getting better at learning and solving problems well into adulthood. When adults and younger learners both listened to a foreign language CD for seven days, the adults scored significantly higher than the younger group on a vocabulary test. This result demonstrates that mature brains can process and retain new information more efficiently, reflecting years of accumulated cognitive growth.
Age shapes how quickly a new language takes hold. Ten participants aged 10 to 15 and ten adults aged 25 to 40 listen to the same foreign language CD for two hours a day over seven days. On day seven, everyone takes a 50-question vocabulary test. The adults score significantly higher — their average correct answers nearly double those of the younger group. That gap suggests adults pick up new vocabulary more quickly under these listening conditions than younger learners.
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.
