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.

If you ever rode in a cable car, ski lift, or gondola, you know they make moving over obstacles like lakes, valleys, rivers, or even up steep mountains seem easy. Though it would be pretty difficult to build a full-size cable car in your home, if you have a Mindstorms® kit, you can build a working-model cable car of your own. The engineering challenge is to build a LEGO® cable car that can travel across a string you have suspended somewhere in your house (between two pieces of… Read more

Science Fair Project Idea
Make a pinhole projector (see ). Use the pinhole to project an image of the Sun onto a wall or a piece of paper. Do you notice any dark spots on the projected image? Trace the projected image and count the dark spots. Use your pinhole projector to make images of the Sun at the same time of day for several consecutive days. How does the pattern of spots change? Can you use your data to figure out how fast the Sun rotates? Sunspot activity rises and falls with an 11-year cycle. At this… Read more

Virtual reality (VR) headsets are becoming increasingly popular with consumers for things like viewing 3D pictures and videos, or for playing video games. However, dedicated gaming headsets like the Oculus Rift® and PlayStation® VR can cost hundreds of dollars. Some headsets, like Google Cardboard™, which is literally made out of folded corrugated cardboard (Figure 1), are much cheaper because they can use any smartphone as the screen. Figure 1. A Google Cardboard headset… Read more

Have you ever noticed that the salt you are using says it is "iodized"? Iodine is an important micronutrient, which means we need it in small quantities to be healthy. Because iodine is rare in many people's normal diets, it is added to table salt. Then when people salt their food, they are also adding this important micronutrient. In this food science project, you will use some kitchen-friendly chemistry to investigate which types of salt have iodine added (in the form of iodide) and which do… Read more
