The Best Seventh Grade Science Fair Topics

Create your own electrical circuit for your seventh grade science fair project.

Science fairs are an excellent opportunity to move outside of the core curriculum and delve into a scientific subject that excites you personally. It is also an opportunity to be creative in your presentation. Of course, not every science fair project is appropriate for all grade levels. Fortunately, there is a wide range of web sites containing detailed information on some of the most amazing science fair projects specifically designed for seventh graders.

Electric Circuits

Learning about electricity and electric circuits can be a lot of fun. However, like any project that uses electricity, safety is an issue. There are kits available that allow young students to experiment with different ways of creating an electric circuit. These kits allow students to learn about resistors, transistors, motors, parallel circuits, batteries, transformers, FM radio and AM radio, among other topics associated with electric circuits. Use a kit to record radio signals, light up LEDs and demonstrate your knowledge of electronics to your friends and teachers.

Haze Monitors

Many seventh graders are concerned with the damaging effects of pollution on life on Earth. Experimenting with a haze monitor is an excellent way to become involved in measuring the movement of pollution throughout the planet's atmosphere. Haze monitor kits are available for purchase online. They are easy to use and safe. They work by detecting how much of sunlight actually makes it to the ground. Because pollution either absorbs or reflects sunlight, if we know how much light should make it to the ground, we can determine how much pollution there is in the air. Students can detect carbon dioxide emissions, volcanic ash and other types of air pollution.

DNA

DNA is the blueprint for building a living thing. DNA analysis is used to perform a wide range of important functions, including finding dangerous criminals and tracking family trees back through time. By purchasing a DNA kit, you will learn how to extract DNA, store it safely, and perform a variety of fun and exciting experiments. Kits typically provide instructions for setting up the lab and carrying out experiments from the hypothesis stage to the conclusion stage.

Chemistry

Chemists spend their time working with different chemicals and determining what core elements things are made of. Chemistry kits typically come with beakers, beaker stands, solutions and all the materials necessary to carry out some amazing chemistry projects. Use these kits to create potato stamps, invisible ink, saturated solutions and many other impressive chemical mixtures.
