Students in 8th grade must select an engaging topic of their choosing, acquire knowledge on it and create an impressive display board to present to an audience.
Implement an experiment that explores the scientific method, such as discovering how much air pressure it takes to inflate a balloon or which types of water are the hardest for creating soap bubbles. Children could also study fertilizer runoff or investigate whether stress affects body temperature.
Rube Goldberg Machine
American cartoonist Rube Goldberg first popularized the Rube Goldberg machine, an intricate contraption designed to complete simple tasks through chain reactions. Students participating in this online school science project can design, build and videotape their own Rube Goldberg machine; additionally they learn about kinetic energy’s relationship to mass and speed of an object as well as how simple machines can transform and transfer energy between each step of the chain reaction process.
This chemistry experiment uses the power of oxidation to transform water crystals into hand-warmers, using household items such as iron oxide filings and calcium chloride for their creations. Students can test whether introverts have better memories than extroverts by creating small groups, listening to different genres of music, testing their memory retention before and after, then testing again after. They may be surprised with what emerges! Students will also explore whether music influences plant growth.
This color-changing UV detector provides students with a fun hands-on way of exploring electromagnetic spectrum concepts. The beads change colors when exposed to UV rays even on cloudy days, providing visual evidence that UV exposure damages skin cells leading to wrinkles or even skin cancer. Furthermore, its use helps students recognize the importance of wearing sunscreen, hats and sunglasses for protection.
This fascinating physics experiment is simple to set up and can be repeated again and again, perfect for eighth-graders to demonstrate how objects with centers of gravity seek out the lightest spot possible.
This science fair project introduces fundamental engineering principles, while showing how paper can be bent and folded to surprise observers. The results will astound even experienced observers – this activity makes for an unforgettable experience that’s ideal for eighth graders at any school science fair!
Tunnel of Lights
An 8th grader looking for an enjoyable science project should choose something that piques their interest, making homework assignments into enjoyable experiences that they look forward to undertaking.
This optics experiment employs straightforward physics and engineering principles to demonstrate breathtaking optical illusions that your students will adore.
With this hands-on experiment, kids can explore how different liquids affect surface tension by adding items like salt, vinegar, oil and tea to water. They will observe, compare and document as they add various items such as these into their water solution.
Are white candles burning faster than their colored counterparts? Put this simple but fascinating experiment to the test during an eighth grade science fair!
Students can get an up-close look at DNA through this engaging project that separates cells without using a microscope, then apply their findings to their family tree.
Electrolytes in Sports Drinks
Your eighth grader has just brought home an assignment that should send chills up your spine: the science fair project. In order to complete their science fair project successfully, they need to select an interesting topic, research all they can about it, plan an experiment that tests their theory and perfect making clear presentations.
Thanks to our brainstorming efforts, we’ve come up with a few ideas that any 8th grader can implement themselves or with some assistance from an eager parent.
Make it fun for your students by having them explore the center of gravity in various objects to understand how objects remain upright. This interesting physics project allows them to experiment with various materials while adding an artistic flare. They could become engineers by designing their own battery for power production with this classic Scientific American science fair idea or by performing this experiment to see which melting materials cause faster ice meltoff.
