In the previous articles in this series (see below), you learned some background information about sonar mapping and echo location, you collected some data, and you turned that data into a picture of the ocean floor. This article will provide some information about turning that demonstration into a science fair project.
Background information was covered in a previous article. Older students will need to do additional research. Put some of your research information on your display. Don’t use just words. Include some diagrams and pictures.
If your science fair rules require you to have a problem and hypothesis, you will need to come up with an appropriate question and answer. These are sometimes more difficult to form for demonstrations than for experiments. You might need to do something like “Can I demonstrate how echo location and sonar mapping work?” for your problem and “Yes, I can demonstrate how echo location and sonar mapping work with a partner and a bell.”
The previous articles showed you how to collect your data and create a graph. Do multiple runs of this demonstration to create several graphs. These will look nice on your display.
This is a fairly simple science fair project for a beginner and it can be done in a week or less. Additional help with creating your science fair project can be found in a series of articles about the science fair process. Because the concept is simple, take the time to make a nice display and guide the viewer through your process. Hopefully they will learn as much from this demonstration as you did.This article is part of the Sonar Mapping series. See the list below for links to the other articles in this series.
