Science fair projects provide students with a fun way to combine their natural curiosity and enthusiasm for learning with topics like food, sports and outer space – these experiments are sure to impress judges with their outstanding results!
Explore the chemical reaction between baking soda and vinegar with this classic science fair experiment, perfect for those who love slime!
Volcano
Baking soda and vinegar volcanoes are an engaging way to teach kids about chemical reactions and states of matter, while providing an engaging science project for your classroom. With just a few additional components you can enhance this science project even further!
Try this rainbow volcano experiment from TikTok blog Beyond the Playroom for an easier, less messy volcano experience. All it requires are six small cups on a tray with lemon juice, food coloring and baking soda – but no additional materials will be needed!
Arches
Students gain experience with chromatography through this hands-on science project that separates fall colors. Students develop skills for designing experiments, conducting them successfully, analyzing data and creating graphs as they conduct this experiment.
Cooking food in a solar oven is an engaging way for students to gain an insight into energy. Students also get an introduction into magnetism through this simple experiment, and experience its power with this slime experiment!
Water Strider
Water striders inhabit and hunt in still, slow-moving waters such as ponds and vernal pools, using hydrophobic legs and surface tension to remain at the water’s surface. These aquatic bugs hunt by hovering above it using hydrophobic forces on their legs and surface tension on its surface.
This intriguing experiment allows students to gain a better understanding of surface tension and hydrophobicity. Challenge them to make a bug float on different liquids – or add soap for even greater success!
Liver Bile
Bile is a greenish-yellow liquid secretion produced by your liver that travels through ducts to your gallbladder and then into your duodenum (first region of small intestine). It contains bile acids and salts, phospholipids, cholesterol pigments and other substances.
Bile is produced in your liver to aid the body’s digestion of fats by dissolving them for easier absorption. On average, your liver produces around 800 to 1,000 milliliters of bile daily.
Lava Lamp
Colorful chemical reactions and captivating physics converge in this enjoyable 5th grade science fair project, offering kids an enjoyable way to explore colored water and oil with this winter-themed twist!
This experiment helps kids understand the separation of oil and water and density as scientific principles. When Alka Seltzer tablets react with water, colorful bubbles rise up through an oil layer before sinking back down again.
Floating Egg
Students use this fun and straightforward experiment to determine how much salt is necessary to make an egg float using this engaging STEM challenge for 5th graders and can also be used as part of a science fair project or classroom activity.
Take part in this exciting science project to understand the impacts of soil erosion on our planet and discover how plants can naturally prevent erosion.
Density Experiment
Showcase your students’ engineering abilities with a fun yet straightforward density experiment! This demonstration shows how substances that are more dense form the base of a tower while less-dense layers rest comfortably atop.
Experience how density can impact buoyancy with this engaging salt water experiment! Why do some objects float while others sink? It all has to do with density!
Chain Fountain
This magical chain fountain, commonly referred to as the Mould effect, appears to defy gravity at first glance; however, upon further investigation it has proven much more complex than first assumed.
Bring key scientific concepts alive for kids through engaging experiments and projects! Explore soil erosion, witness plant decomposition, use chromatography to differentiate fall colors, and more!
Water Rotation Experiment
Discover the water cycle with this fun, hands-on experiment. Watch as water vapor evaporates, condenses, and then precipitates as rain, sleet or snow from above.
Students test which model soil holds the most water using everyday food items in this science activity that also introduces capillary action and capillary action theory. It provides an engaging hands-on STEM challenge suitable for 5th grade.
Hydrophobic Sand
Whoever has spent time building sand castles knows the thrill of wet sand clumping together and being sculpted into towers or mermaids is well known, but imagine if this kind of dry sand never wetted at all – that is what hydrophobic or magic sand is all about!
Students can use this sand to explore its behavior when exposed to various liquids, including oil, vinegar and even ice water. Their results will no doubt prove exciting!
