Exploring Human Impact Underwater

Mrs. Weaver’s class has been investigating the following: Humans have a direct impact and responsibility to the survival of marine life. In order to understand this, students have been using the research from Dr. Leila Hatch, a marine noise specialist, who also works with The JASON Project.

In class, we designed a prototype of Dr. Hatch’s instrument used to record sounds underwater. These sounds are downloaded to computers and then analyzed for their significance to various marine life. Specifically, Dr. Hatch focuses on whales and how vessel traffic and other human noise affects these ocean animals.

Below, you will find a video showing our design and testing of a hydrophone (a microphone held underwater). Using the engineering design process of ask, imagine, plan, create, improve, and share, these 5th graders were able to gain a better understanding of how scientists conduct their research and how they can help to improve the lives of living beings. Enjoy!
