Science fair projects begin with curiosity. Discover what causes an egg to float or the rate at which a ball sinks with this physics experiment. Mesmerizing optical illusions provide another means of teaching kids various scientific principles.
Encourage your children to follow their own interests; doing a project that makes a statement about who they are can be much more satisfying!
1. Water Density Experiment
This fun density experiment shows how different liquids with differing densities will form layers on top of one another due to density differences, helping students learn buoyancy in the process.
Explore how to float an egg in water using this easy density demonstration, using common household ingredients! Additionally, try taking your experiment one step further by adding one additional ingredient for an incredible homemade Lava Lamp effect!
2. Water Temperature Experiment
Do differences in water temperature influence how quickly chemical reactions happen? Find out by dropping an Alka-Seltzer tablet into different temperature water, recording its fizzing time and volume using a smartphone fitted with a sensor app.
Use this science experiment to gain the skills required for graphing data and adding error bars (for more information refer to How to Graph Data Experiment Guide).
3. Paper Cup Structure
Paper Cup Pneumatic System: Use paper cups to create a pneumatic system and study air pressure.
One embodiment of an inflexed edge 4 can be produced by extending and bending the annular skirt 31 of the bottom of paper cup 1. This helps decrease stacking space while increasing leak-proof effectiveness and decreasing gapping between stacked cups, providing increased durability and strength over other designs.
4. Fire Experiment
Students of any age will enjoy this engaging science experiment which explores how sunlight causes fires.
By following a similar procedure to flame photometry or flame spectrometry, this experiment will identify which colors various metal compounds emit when burned.
Teachers must closely supervise this experiment since methanol is highly toxic and flammable, and students should work in an area with sufficient ventilation.
5. Laundry Detergent Experiment
Laundry detergents contain enzymes to breakdown protein-based stains in laundry detergents, including mustard and ketchup stains. As part of Novozymes’ science fair experiment students tested wash cloth strips soaked in mustard or ketchup with detergents containing proteases versus those without.
Students can gain an in-depth knowledge of water filtration with this engaging project idea from All Science Fair Projects. Students can compare filtration systems at various levels of vinegar dilution and density-related factors to better understand this important subject matter.
6. Water Pollution Experiment
Students use this Earth Day activity to understand acid rain, an important water quality issue. This experiment is suitable for kids in grades 5 – 8.
Students participating in this water pollution experiment will discover that clean water may not always appear clear. They’ll “taste” invisible substances dissolved in tap water and observe how plants absorb pollutants along with their own moisture.
7. Newton’s Cradle
Newton’s Cradle may look like just another desk toy, but its elegant demonstration of fundamental laws of physics and mechanics should not be disregarded. The system works by transforming potential energy to kinetic energy for conversion.
As each ball hits its counterpart on the opposite end, it comes to rest and almost instantly transfers all its energy onto it – causing its height to increase accordingly. The last ball then makes another attempt and returns back up towards where the first one started from.
8. Lung Capacity Experiment
Lung capacity measures the volume of air that a person can breathe in and out at one time. Students can experiment with how their lung capacity changes with exercise.
For this experiment, each student should create their own lungometer by cutting in half a plastic drinking straw to serve as their mouthpiece, inserting it into the lungometer’s tubing and connecting to their personal mouthpiece.
9. Personality Test
Exploring science can be exciting, and these amazing science fair projects can engage students with various subjects – biology, chemistry, physics or environmental. From these experiments they’ll find motivation to learn something new!
Find out if introverts have better memories than extroverts in this fun experiment, and also explore other personality traits!
10. Shampoo Experiment
Students can learn the ingredients found in shampoo, and conduct an experiment to see whether homemade or store-bought shampoo works better than regular soap. This chemistry project would impress judges.
Magnets and mud make for an exciting science experiment! Take part in this simple chemistry project to learn about spherification.
