Science fair projects should inspire curiosity in children about the world they inhabit, while providing hands-on experiments to teach the fundamentals of chemistry and physics.
Explore the properties of polymers through this simple yet engaging experiment. It combines both chemistry and engineering for an amazing results!
Rusted metal and bananas that turn brown are both telltale signs of oxidation, an important chemical process which children can learn more about with this interesting science fair project idea.
Students in sixth grade science fair projects can experiment with genetic traits they inherited through this engaging sixth-grade science fair idea. Although adult supervision will likely be needed for proper completion of this experiment, it’s a simple yet enjoyable way to introduce inheritance concepts.
Students looking for successful seventh-grade science fair projects won’t go wrong by selecting classic experiments to learn valuable lessons, from moldy bread experiments to potato batteries – classic experiments are sure to stand out at any fair!
This fun top-building game helps children understand gravity and balance. Players use strings to catapult spinning tops into an arena, scoring points for every remaining top. This hands-on project resembles gasing pangkah – a traditional Malay sport.
Blown bubbles have long captured people’s fascination, whether as an enjoyable pastime, meditative practice or as a symbol of transience and fragility. Furthermore, this simple activity provides plenty of opportunities for science experiments.
Conduct an easy experiment to explore how bubbles react to different materials with this simple exercise. Wet a straw and try sliding it into an existing bubble without popping it!
On a windy day, observe a bubble as it slowly climbs higher and higher into the sky. How does its trajectory differ depending on where the wind blows?
Lip balm is an indispensable beauty essential, and many of us have our favorite options. Some use it to soothe chapped lips while others simply like the taste or scent.
This STEM project allows students to compare the ingredients found in various lip balm varieties and rank them according to their personal preferences, helping them understand why certain products are more popular than others. Since this is an experiment, students should ensure they formulate an objective hypothesis and test it appropriately.
Kids love playing with sidewalk chalk as a classic summer activity, but you can take this pastime one step further by turning it into an engaging science experiment!
Plaster of Paris is an integral component of sidewalk chalk and hardens through an exothermic reaction similar to what gives concrete its strength.
This straightforward science experiment using a basic Zip-top bag teaches children how water evaporates and also introduces them to osmosis, using household materials.
Spring Weight Experiment
With this fun science experiment, students can explore Hooke’s Law (F=x; force and displacement are proportional). By adding masses to a vertically suspended spring and measuring its distance traveled, they can plot weight against stretch; then find their best-fit line; the slope will give the spring constant value.
Use a well-known baking soda and vinegar chemistry demonstration to educate eighth graders about chemical reactions. Bring together engineering with physics by inviting children to build paper cup structures capable of supporting their weight, then watch as their mind is expanded through construction of structures capable of supporting these weighty individuals!
Students can explore the chemical processes behind their favorite drinks with this fun chemistry experiment and test to learn about acids and bases with this simple pH test.
This experiment illustrates the difference between endothermic and exothermic reactions with an impressive color change! Students can conduct this experiment using soda and other common household chemicals.
Future forensic scientists can discover how fingerprints are classified with this project that equips them to use magnifying glasses and muriatic acid!
Solar-Powered Desalination Device
Kids can gain insight into solar energy with this simple experiment from ThoughtCo. In addition, they can examine their favorite sports drinks’ electrolyte contents by participating in this fun project! Both projects will spark their creative juices!
Science fair projects for eighth grade can give kids an outlet to express their inner chemist. From grinding tablets with mortars and pestles to heating chemicals over Bunsen burners, kids will find plenty of opportunities to unleash their inner scientist. Furthermore, eighth grade science fair projects can allow kids to put laundry detergents through rigorous tests by watching how they wash clothes and fabrics.
Paper Cup Structure
Students interested in engineering will love this fascinating science fair project that showcases friction. Additionally, this classic experiment provides valuable lessons about momentum.
In this project, you need two paper cups with one sitting on its side as the rocket base part. The second cup should then be decorated with wings and crown to complete its rocket structure before inserting rubber bands through its holes and tightening tightly around its exterior surface.
