3rd Grade Science Fair Projects

Instructor: Derek Hughes
Science fairs are an exciting way for students to research a topic and create interesting projects demonstrating what they learned. This lesson will provide some examples of science fair projects for third grade.

What is a Science Fair?

If you are already a teacher, have seen a movie or TV show about teaching, or are broadly aware of education, you've probably heard of a science fair. However, I will provide a quick definition here, in case you haven't. A science fair is an event in which students' present projects they've created after researching a topic or conducting an experiment.

Science fairs are suitable for all ages, but the younger the group of students, the more guidance and instruction they will need. This lesson will go through several science fair projects done by third grade students. These examples will provide you with ideas you can pass on to your students, who will most likely need help starting a science fair project. However, the examples are not the only kind of science fair projects third grade students can do. Additionally, if you assign your own, make sure the topic is not too complicated and falls within your school or state's science standards for third graders.

Ecosystems

Joe and Kim are third grade students who will be participating in their school's science fair. In class, they have just finished a unit about ecosystems and are interested to learn more about specific examples of ecosystems. Their teacher suggested that they use that interest as a starting point for their project. After some initial research, Joe and Kim decided to do their research on coral reef ecosystems, specifically, the Great Barrier Reef.

Ecosystems serve as a good starting point for many third grade science fair projects. There are many different kinds of ecosystems that students can research. Additionally, there are various issues surrounding large ecosystems, such as extinction and preservation. Like Joe and Kim, using the concept of ecosystems as a starting point might help your third graders come up with a project idea.

Environmental Issues

Two other third graders, Sean and Eddie, are also searching for a project idea. One day their teacher heard them trying to figure out what happens to the paper they throw in the classroom recycling bin. She suggested to them that they begin investigating recycling for their science fair project. Eventually, Sean and Eddie decided that they were going to create a school-wide recycling program for their science fair project.

Investigating how humans affect the Earth can make for very interesting projects. Students can often discover ways they can improve their school, home, or community's conservation efforts, which means their projects can have real-world effects. Using environmental issues in their science fair projects allows students to learn about the world around them and collaborate with other people in the school, at home, or in their neighborhood.
