The hypothesis is that dogs become more deaf as they grow older.

You will use a high frequency sound generator to test the hearing of different breeds of dogs, both young and old.

You will need a young and an older German Shepherd, a young and an older Labrador, a young and an older Terrier, a young and an older Golden Retriever, a young and an older Beagle Shepherd, a young and an older Poodle, a dog trainer, a box of dog biscuits, and a high frequency sound generator.

The results showed that the older dogs had poorer hearing abilities compared to the younger dogs, especially for the German shepherd and the Poodle. The hypothesis that dogs grow more deaf as they grow older was proven to be true.

This science project is interesting because it shows how age and breed can affect a dog's hearing ability. It also shows how dogs can hear sounds that are of a higher frequency range than humans are able to detect.

To improve the reliability of the results, you could use a larger number of breeds or test dogs of a wider age gap. You could also consider repeating this science project by comparing the difference in hearing deterioration between small breed dogs and larger breeds.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
