7 Science Project Ideas for 7th Graders
Science is everything. Without science, all of the great things we enjoy, from frozen yogurt to space travel, would not be possible.
For seventh-graders, learning about how things work becomes increasingly important and plays a vital role in their learning and development. As a science teacher, it’s essential to encourage young people to develop an interest in science.
One way to get seventh-graders excited about science is with science experiments. Here are seven science experiments that seventh-graders will love.

Design a Solar Oven
This experiment allows you to make a solar oven using everyday household items. When your oven is complete, you’ll be able to cook outdoors using only the sun’s energy.
This experiment teaches students about thermal energy, convection, reflection, and other physics.
Purify Water With Charcoal
Many households have water purifying pitchers or systems with charcoal filters, but most people don’t know how charcoal cleans and purifies water. This experiment will show how charcoal removes molecules from water.
You’ll need a measuring cup, teaspoon, two baby food jars with lids, activated charcoal, water, and red food coloring for this experiment. At the end of this experiment, students will see that the charcoal removed the red food coloring molecules from the water.
Make Eggs Explode
Making eggs explode teaches students about pressure. Seventh-grade students can participate in this experiment by poking a pinhole on both sides of an egg and blowing out the insides.
After the eggs are empty, the empty shells are placed on a stand and filled with hydrogen. The hydrogen will rise to the top of the egg, and air will accumulate at the bottom. Soon the gases within the egg will get hot, the hydrogen will ignite, and the egg will explode.
Determine the Effect of Salt on Water
The effects of salt on water demonstrate to 7th grade science students how salt can prevent water from freezing. You begin this experiment using three freezable cups of water. In the first cup, students will add one teaspoon of salt.
Add two teaspoons of salt to the second cup. Do not add salt to the third cup. After being placed in a freezer overnight, students will observe whether any freezing has occurred.
Determine the Dissolving Time of Painkillers
Finding new and exciting science experiments for seven graders can sometimes be challenging, which is why it’s essential to use reliable resources like Adobe Education Exchange.
By taking advantage of such expertise, you can find and create cool experiments that young people will love, like determining the dissolving time of painkillers.
How fast painkillers dissolve is an excellent 7th grade science project that will teach kids which painkillers work the fastest, and it only requires three separate cups of water with different pills placed in each one. Students will time each pill to see how long it takes to dissolve.
Study Photosynthesis
Photosynthesis is a crucial process to most plant life on earth. For this experiment, seventh-grade students will need three types of plants placed in varying lighting conditions to observe how the plants grow under the different light conditions.
Remove Oil Pollutants From Water
This experiment for seventh-graders requires minimal supplies, is easy for students to conduct, and demonstrates three methods to remove oil from water.
Have your student fill three jars with water and add motor oil to each jar. Once filled, you can guide your students on using sand, a spoon, or cheesecloth to remove the oil from the water.
7th grade science can be a cool and exciting class that will get students interested in learning and help them develop a love and appreciation for science. For more science project ideas, check out Adobe Education Exchange.
