Ideas for a 7th grade science project include using common household materials to make clouds or self-inflating balloons. Interesting projects can be made with very little expense.Continue Reading
Seventh graders typically have a better understanding of scientific subjects, such as chemistry and physics, which will provide a wider variety of options for interesting science fair projects. Commonly used household items like baking soda and vinegar can produce some interesting results, and urban legends — such as the one about Pop Rocks and soda — can also be turned into a fun experiment.
For projects that don't require chemicals or expensive materials, use the Internet to conduct surveys. These surveys can be used to find the answers to questions such as "Does the weather really affect mood?" and "Does color preference change with age?"
Keep in mind that the basic elements of a science fair project include a hypothesis, a procedure for testing and a report of the findings.Learn more about K-12
A good science fair project at any grade level should include a hypothesis, background research, an investigation, data collection and a presentation of the results. An example of a successful fifth grade science project is exploring skyscraper design with Lego.Full Answer >
A good 8th grade science experiment should center around use of the scientific method, particularly if the project will be graded or displayed at a science fair. A topic that interests the student can lead to a positive experiment experience.Full Answer >
A testable science question for 6th grade is one a student can use to design and carry out an experiment or science fair project. Subjects to investigate include chemistry, botany, environment, health, weather and geology. A testable question may follow the format "How does A affect B?"Full Answer >
A sixth grade science fair entry is judged based on how well the entrant understood and applied scientific methods in developing the project, according to Discovery Education. Criteria listed by the University of Southern California include quality, ability to clearly explain the project, and actual application to the real world.Full Answer >
