Science fairs represent an essential milestone in students’ development as scientists; this event serves as their first chance to design and conduct scientific experiments outside of an instructor-led lab period.
Showcase your 8th graders’ chemistry skills through experiments that yield stunning results, from creating glitter-flecked rainbow slime to testing how various fluids react against one another, these projects are sure to dazzle and surprise.
Solar Oven Project
Students can combine engineering and physics to construct a solar oven capable of cooking s’mores in this project, learning about solar energy and heat transfer as they go along.
Students will demonstrate how air pressure affects movement with this straightforward science fair project. They can customize it to explore additional variables like weather or reaction time.
With this fun experiment, students can witness firsthand how water can help a balloon resist heat by filling its interior space instead of air. Students can experiment using various amounts of liquid for different results! This experiment serves as an effective introduction to chemistry for 8th graders as they witness its processes through red onions spherification or edible science creation; they may even discover DNA through similar demonstrations!
Candle Carousel Project
Candle carousels provide a fun and engaging way for students to learn the principles of convection and forces. By employing their creativity in this simple experiment, students can demonstrate how the linear velocities of two or more candles affects how fast a paper carousel spins.
Science experiments for 8th grade can be fun! Explore reaction time effects by testing whether hunger or fullness has an influence on how long soap bubbles last; or compare reaction times of dominant and non-dominant hands; or use this chemistry project to uncover how acid rain damages structures like stone, concrete and asphalt pavements.
Newton’s Cradle Project
Students interested in physics should try the Newton’s Cradle project to demonstrate conservation of momentum. This experiment features five or six shiny silver balls connected by string; when one ball is pulled backward and released it causes all the other balls to start swinging – as all balls share equal density, their momentum transfers evenly.
Explore chemistry through this dynamic demonstration that shows how adding soap to milk alters its surface tension, enabling water molecules to flow around a glass more freely and chase each other around it. It is designed specifically to help 8th graders comprehend how chemical reactions occur.
Engaging students in an engineering challenge that entails them developing devices capable of balancing a full glass of water is an excellent way to teach teamwork and develop patience. This engineering challenge encourages teamwork among your pupils.
Engineering Projects
Implementing engineering projects into their science fair gives students an opportunity to use skills they’ve acquired over time to design, create, and test solutions. Incorporating engineering projects also prepares them for STEM careers.
Develop a fun twist on Newton’s Cradle to demonstrate energy transfer and momentum, or challenge students to construct a wind-powered car to gain insight into engineering and physics concepts.
Chemistry enthusiasts can make use of air vortices and electrolysis to demonstrate how water actually forms from two gases; other experiments include measuring evaporation rates, testing how music impacts plant growth and tracking animal footprints.
This hands-on project tests the ability of different surfaces to hold objects securely while measuring friction. You’ll only need minimal materials and supplies – and gain insights into real world applications of the concept!
Chemistry Projects
As eighth grade science fair projects can provide budding scientists with an opportunity to hone their biology and chemistry knowledge, there are a variety of fun projects for budding scientists in eighth grade to expand their understanding. Tinkering with basic root beer recipes is a fun way to demonstrate chemical reactions at work in temperature sensitive conditions, as is creating hand warmers from scratch for use as hand warmers – or investigating seed dispersion with simple paper cup structures!
Selecting an engaging science fair project idea shouldn’t be difficult when students have an interest in what they are exploring. To streamline this process, students should first review any specifications provided by their school science fair organizers as well as any queries or questions they would like answered.
