Crafting an excellent science fair project takes more than simply conducting experiments: students must conduct extensive research on their chosen topic, conduct trials and examine results before concluding their work.
Provide your 8th graders with all they need to make an impressionful display with these incredible projects! Your students will have fun exploring exciting scientific facts while discovering interesting scientific theories – they may also gain knowledge on topics like gravity and plant growth!
Paper Cup Structure
Students will be challenged to build a structure capable of supporting two cups in this physics and engineering science fair project idea. It provides an engaging opportunity for creativity development as well as engineering challenges! This timed experiment offers plenty of learning potential!
Discover the wonder of dry ice with this hands-on kids science experiment! Its impressive chemical reaction will certainly impress eighth graders!
Paper may appear soft and delicate, yet when interleaved with other papers it becomes very strong and stable. This experiment teaches children about centrifugal force and its power over vortices.
Find out if shampoo commercials really do work with this easy, fun science experiment designed to demonstrate surface tension and classification. This one provides great learning opportunities.
Fire Chemistry
Chemistry projects can be both exciting and educational for children, making them great science fair projects. Exploding fire experiments are an especially fun way to impress crowds during presentations; just make sure that students take precautionary steps when performing this type of experiment!
Other chemistry experiments investigate the chemical properties of substances like salt and sugar. These experiments are generally straightforward to perform, making them an attractive option for science fairs.
Other exciting chemistry projects for children to try include the Water vapor experiment on iRex. This provides a fascinating demonstration of how water vapour can take different shapes and structures when exposed to different environments, while crystal growing projects provide children with the chance to see how different chemicals influence how fast crystals grow.
Laundry Detergent
Laundry detergent is an indispensable part of everyday life, yet their inner workings may remain mysterious to most of us. In this eighth grade science fair project, biological and non-biological detergents will be put through their paces by being put through tests designed to gauge their ability to remove different types of stains from cloth washed in hot or cold water.
Your project will involve testing whether washing fire-retardant fabric strips strips their fireproof properties through washing. This hands-on project combines both chemistry and physics, which should captivate bystanders at your school science fair. Materials needed are 100% cotton cloth cut into equal squares; several bottles of laundry detergent with and without enzymes (Proteases, Mannanases, Amylases & Lipases) listed as ingredients as well as a colorimeter for measuring colors accurately.
Acid Rain
This experiment shows how acid rain impacts the environment and plants. It simulates how harmful gases, such as sulfur dioxide and nitrogen, enter the atmosphere through human activities like burning fossil fuels and vehicle emissions and combine with water vapor to form low pH acid rain resulting in low pH acid raindrops.
This simple flower experiment helps students observe the effects of acid rain on plant growth, foliage and health. This activity makes a perfect hands-on STEM activity for Earth Day events or science fair projects and to understand pollution’s effect on our planet.
Students will investigate the physical properties of liquids while creating a colorful density column! This experiment also serves to teach center of gravity. Students will then create their very own Rube Goldberg machine utilizing different physics concepts in order to complete this engineering challenge!
Plant Growth
Encourage your learners to put their green thumbs to work with this simple plant growth science experiment! They’ll grow plants under various lighting, soil and water conditions in order to observe how each aspect affects its growth.
Explore both chemistry and physics with this eighth grade science fair project idea! Students will gain an insight into rusting by watching how acids accelerate it chemically.
Students will gain insight into what lies behind a plant’s vibrant hue with this hands-on chromatography experiment. By using liquids of various densities to separate and create an eye-catching density chart.
