Seventh Grade Project Ideas (477 results)

Science Buddies' seventh grade science projects are the perfect way for seventh grade students to have fun exploring science, technology, engineering, and math (STEM). Our seventh grade projects are written and tested by scientists and are specifically created for use by students in the seventh grade. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, seventh graders can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples. Read more

Science Fair Project Idea
How much difference does the spiraling motion of a well-thrown football make on the distance of the throw (compared to wobbling, or end-over-end motion of the ball)? Think of a way to reproducibly produce the desired ball motion and launch it with a constant force to find out. (For more information on the physics, see Gay, 2004.) Read more

Safety Producing pulp from plant material requires that the plants be boiled in a caustic soda solution. Adult supervision is required, and proper precautions must be observed for handling the strong base.
  • Wear protective clothing and eyewear.
  • Use adequate ventilation.
  • Always add the soda ash (a strong base) to water, not water to soda ash.
  • Use stainless steel or enamel cooking vessel, not aluminum.

Have you ever woken up in the middle of the night just not feeling well? Maybe your mom or dad gave you some medicine and you felt better after taking it. Medicine is a great tool in the fight against an illness, but medicine can be a poison if too much is taken. Similarly, household products can clean your home and make it smell great, but if eaten, can be poisonous. That is why most medicines and household products are stored in childproof containers. But are childproof containers really… Read more

Take shots at a set distance from the basket, but systematically vary the angle to the backboard. For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to illustrate your conclusion. For a more advanced project: Use your knowledge of geometry and basketball to come up with a mathematical expression to predict your success rate as a function of angle… Read more

Walk into a fitness club and what kind of music do you hear? Slow, sparkling, relaxing music? Or driving, "up-tempo" songs that are designed to encourage you to move? Fitness clubs and other businesses, like restaurants and grocery stores, use background music to set the mood and to determine how fast they want their customers to move. The tempo of the background music is a key component to the environment that businesses want to create. Tempo is an important number or word inscribed by a… Read more
