Ideal Science Projects for the Seventh Grade Science Class

There are several good ideas available for science fair projects for your 7th grade science class. The science project is meant to help individual children to employ critical analytical skills and use them to investigate different scientific phenomena. For best results, the children are left to decide which science project they would like to carry out. This allows them to be independent as well as unique in their presentations. This way the whole objective of the science project is met.

One of the most popular science projects for the 7th grade science class is the paper chromatography project. This science project helps the children investigate the method of separating the different components of a single mixture. It is a fun filled project for the seventh graders as they are able to do the experiment over and over again using different mixtures. All the student needs for a perfect experiment is a number of coffee filters and solvents which are easy to find around the house. The child can use colored markers as the mixtures to perform experiments on.

If you are having a hard time trying to teach your 7th grade science class the basic differences between acids and bases, then this next experiment is the best project for you and your class. The red cabbage indicator experiment is ideal for such situations. Indicators are substances used in many scientific projects to investigate whether a liquid is an acid or a base.

The indicator will change to different colors based on the pH of the liquid. Many people think that indicators can only be fund in laboratories but this is not true. Most plants such as the cabbage contain natural indicators. The red cabbage indicator is extracted from the leaves of the red cabbage and so it is easy to find. The indicator is usually purple in color and can be used to test the different pH levels of various liquids.

Science Projects for 7th Graders: 3 Places to Inspire Project Ideas

Thinking of science projects for 7th graders can be a daunting task. Seventh grade is usually the year students’ start doing science projects at school. Usually about the middle of the year, students come home saying, “Science fair is coming up, and I need a project, NOW!” Step one is finding an idea, but this is usually the most difficult part. Where do you look for ideas for science projects for 7th graders? Here are three places that will introduce students to many different scientific ideas and help them find a stellar idea of their own.
