Science fairs provide students with an engaging opportunity to both learn and have fun while participating in competition with their peers. Students get to display their work while competing against their fellow participants at this type of event.
Introduce supersaturated solutions and acids and bases in an engaging chemistry lesson with this timeless experiment! Also make it an introduction to acids and bases.
1. Growing Crystals
Crystals are solid substances where atoms and molecules have been organized in an ordered, repeating pattern. With these engaging chemistry experiments for kids, children will learn all about crystal formation using materials found right in their kitchens!
An engaging experiment to teach about supersaturated solutions and light refraction, creating crystals with your students’ names is sure to keep the learning engaged!
2. Pipe Cleaner Experiment
Students discover circuitry through this open-ended activity that combines art and science. By using pipe cleaners and LED lights to create illuminated works of art.
Students use pipe cleaners to shape one end into an unusual shape while leaving the other straight for use as a handle, then dip that shape in paint for printing purposes.
3. Growing Bacteria
Bacteria are ubiquitous single-celled organisms that can be found everywhere. Although not visible with naked eye, bacteria play numerous helpful and harmful roles within our ecosystems.
Students using a bacteria testing kit and some sterile swabs can conduct door handle tests to see which ones harbor the most germs, making this project an excellent way to emphasize hand washing as an essential way of protecting ourselves against germs that spread.
4. Miniature Coastline
Explore erosion in an engaging and hands-on way with this ocean science experiment. Make this project part of a lesson plan on slow earth changes.
Watch gravity and inertia come into play with this straightforward 4th grade science experiment! Simply spin beads for this engaging lesson that illustrates matter and force.
Demonstrate Newton’s Law of Motion with a balloon, paper cup and clothespin! After this activity is complete, kids can color with their new rock crayons!
5. Building a Projector
Students use projectors to view images on distant surfaces. This engineering science fair project also helps them learn about convex lenses and how the brain processes images!
Investigate density with this exciting chemistry experiment designed for 4th graders! They will create both chemical reactions and beautiful artwork simultaneously!
Help your students learn Newton’s second law with this gravity experiment! It is an excellent way to reinforce inertia with children!
6. Elevator
Engineering activity provides fourth graders with a great way to explore the inner workings of elevators. A simple contraption enables students to lift a small box of cargo using only height of the shaft and turning handle – and all while having fun!
Place four spindles evenly spaced about four inches apart across the wood piece, as illustrated in Figure B. Tie a string to the bottom of your cardboard elevator box and pass it over spindle 2. Using your fingers, turn spool 2 using it’s knob.
7. Seismometer
Earthquakes are fascinating natural events, with seismic shockwaves ranging from mild tremors to more violent shaking. This fun STEM project shows kids how to make their own seismograph using basic materials.
An iconic science fair project that never disappoints. Students observe how close an object must be to a magnet for it to attract it; this experiment also serves to illustrate gravity’s laws.
8. Wigglebot
Nothing gets children more engaged with science than hands-on experiments! These 4th grade science activities teach about physics, biology, engineering, and chemistry – making learning science fun!
Explore Newton’s laws of motion with this captivating physics demonstration that highlights gravity and inertia. Uncover why Sharpie markers float, as well as what happens when food items decompose inside a plastic bag. Dance, race and scribble your way through super Wiggle Bots designed and assembled by kids using recycled bin materials plus extra Teachergeek components!
9. LED Flashlight
Science fair projects for 4th graders give children a fun way to explore science by asking questions and exploring answers with hands-on projects. Through such experiments, 4th graders learn important scientific concepts in an enjoyable and memorable way.
Show children the basics of electricity with this simple paper flashlight experiment and teach them about diffusion by using Skittles as part of this colorful experiment.
10. Hovercraft
Explore gravity and mechanical advantage with this engaging physics experiment for kids! They will construct a hovercraft that glides over surfaces on its bed of air while learning about friction, air pressure and air resistance along the way.
This creative science demo may look more like magic than an education lesson, yet it teaches children vital biology concepts. Kids will be amazed to watch as a Sharpie marker dissipates into water illustrating solutes and solvents.
