Science fair projects provide children with a direct way to explore scientific concepts through experiments and research. Most often, they involve posing a question or hypothesis that is then investigated through various experiments and methods of investigation.
Kids can discover chemical reactions with an easy erupting volcano experiment or put an egg in vinegar to test its durability over time. They could also try out various recipes to grow crystals or create an alka seltzer boat to demonstrate temperature’s effect on water density.
Hovercraft
Learn the fundamentals of physics through this entertaining experiment! Create your own hovercraft using a CD and the pop-top lid from a plastic bottle, and test its ability to glide on various surfaces by increasing or decreasing air volume.
Apply the scientific method to assess whether mood rings work. This activity provides children with hands-on learning about solutes and solvents!
Projector
Explore how sunlight reaches our earth with this hands-on science experiment that involves creating a simple solar oven. Plus, this activity serves as an engaging way for kids to learn about renewable energy!
This experiment may appear miraculous, but it’s actually all science at work. Watch as adding glycerin to soap bubbles creates layers that stay together over time.
Utilize some simple ingredients to demonstrate the properties of water and inspire students to apply scientific methodology.
Machines
Students learn surface tension while designing an exciting lava lamp STEM project. This STEM activity also introduces acids and bases.
These simple machines come together in this engaging science experiment using leverage, inclined planes, wheels and axles – perfect for helping students grasp Boyle’s Law!
Soap Bubbles
No child can resist chasing after soap bubbles or making them sparkle – this timeless pastime teaches youngsters all about physics, geometry and surface tension! This fun experiment also equips children with valuable education about these subjects!
This classic science fair project provides 4th graders with an opportunity to learn about energy and natural resources while being easy and impressive! Give it a try either at home or in class and see which of your students enjoys it the most!
Crystals
Try this crystal growing chemistry project for an engaging science experiment that’s easy and fun for children of all ages to set up! This activity helps them learn about density, adhesion and cohesion while learning all about colorful crystals!
Encourage kids to explore other variables, like adjusting temperature or humidity levels in the solution, to see how these affect crystal formation and size. This fun science experiment for kids also helps them understand diffusion more thoroughly!
Dinosaur Cage
Use a cardboard box and some binder clips to craft an eye-catching dinosaur cage for this science fair project.
This experiment provides a fun and easy way to understand how plant-eating dinosaurs managed to find enough food.
Slime has become a hugely popular toy craze among children, but creating it as part of this science fair project provides them with an excellent opportunity to learn chemistry as well as about osmosis and its effect.
Wind Speed
Use a homemade anemometer to monitor wind speed throughout the day and compare it with neighbors’ results.
Students participating in this science fair project will create their own anemometers using five cups to capture wind. Furthermore, they’ll test different heights and watch as wind speeds change to understand turbulence’s effect on wind speeds.
Kaleidoscope
Kids will love this interactive experiment that allows them to see how light travels through a kaleidoscope and understand its properties – an ideal way to teach reflection and refraction!
Perler beads make this DIY kaleidoscope for children an engaging classroom activity and fun activity to replicate at home, teaching children about colors and patterns as they learn.
Magnetic Attraction
Utilizing their findings from their Explore phase investigations, have students conduct experiments to see whether materials such as glass tiles and aluminium foil reduce the magnetic force required to lift a paperclip. Have them record their observations on a student sheet.
This hands-on experiment provides 4th graders with an engaging way to learn about supersaturated solutions while having fun! This project can also serve as an introduction to the rock cycle.
Tornado
An airborne tornado is a large column of air that forms an annular funnel-shaped cloud and collects debris, so this experiment shows children how it works using water, glitter, and plastic bottles!
Start with two 2-liter bottles, food coloring, legos or any small items for debris, and duct tape. A tornado connector tube can make joining them easier without drilling or glueing; simply purchase online for just a few dollars more and connect them easily!
