Science fair experiments offer students an engaging way to explore scientific subjects. When selecting projects for this event, avoid those which test products, such as how long batteries last or whether detergents remove stains.
Make nature come alive for children with this fun project about changing colors in sugar water! They will learn about density with this straightforward experiment.
Solar System
The solar system encompasses everything that orbits around the Sun, including eight planets with their 173 known moons, dwarf planets, asteroids and Kuiper belt objects. Children learn how to identify planets based on size and order using mnemonic devices for recalling.
Unthrall your students to the power of air pressure with this incredible non-Newtonian fluid experiment and demonstrate its amazing results! It’s also an engaging way to teach about friction and air pressure!
Cockroaches
Cockroaches prefer tight, dark spaces like crevices and gaps to hide in, where they emit an offensive musty scent and leave behind droppings and shed skins.
Use a bright flashlight to inspect these spaces for live cockroaches, inspecting where utility lines enter rooms to see if there are any large openings that cockroaches could enter through, as well as checking nooks and crannies where utility lines meet to see if there are any large openings that allow access.
Milk Plastic
Plastics are typically manufactured using petroleum-based products; however, during the early 1900s casein plastic production became popular as an alternative material source. This technique allowed makers to make buttons, decorative buckles, fountain pens and even fancy comb and brush sets using this process.
Polymers are long strings of similar molecules connected by bonds. Children can quickly and easily discover their properties with this easy experiment that uses sugar water and Skittles.
Earthquakes
Students take on the role of engineers in this engaging science project. They construct structures to assess their ability to withstand earthquake forces and report back their findings.
Encourage students to keep a journal to record materials, diagrams and observations about their structures as they use this project as an excellent way of teaching geometry concepts! They could even record successes or failures for discussion later. Plus! this project makes an awesome introduction!
Sharpie Markers
Nothing excites kids more about science than engaging them in hands-on experiments! These 4th grade science projects will teach important STEM concepts while the children have fun!
Students will quickly gain an understanding of density with this straightforward experiment. By placing oil in water, students will notice that heavier oils sink while lighter ones float – an invaluable lesson about waste reduction!
Projector
An initial big science project can be daunting for kids, but it provides an invaluable opportunity to teach them how to organize their thoughts and express them coherently. Use this refraction experiment as an example.
This simple transfer of energy science activity requires only household items. It provides an engaging way for children to explore gravity’s power while simultaneously reinforcing safety gear use.
Elevator
Elevators play an integral part in building services by providing quick access to different floors within a structure and transporting heavy goods safely.
Explore physics and engineering with this fun project idea that lets kids design their own elevator. Once complete, test out different designs to see how far their balloon car travels.
Craft a model seismometer to explore Earth science! This engaging project will teach children about earthquakes.
Seismometer
A seismometer detects vibrations on Earth caused by earthquakes and volcanic eruptions. Students can construct this simple horizontal pendulum device, producing data sheet called seismogram.
Grow crystals! Kids of all ages love growing crystals, making this classic science experiment an engaging way to demonstrate supersaturated solutions. By customizing pipe cleaners into names before initiating their crystal growth experiment, students add extra fun and personality.
String of Beads
Students can practice hand-eye coordination and fine motor skills with this hands-on STEM challenge, while simultaneously learning numbers through addition and subtraction, visualizing groups of ten, and practicing estimation skills.
Kids of all ages will delight in this simple but impressive experiment, layering colorful sugar water layers to observe how density affects adhesion and cohesion – a fantastic way to introduce early chemistry lessons!
Marbles in a Cup
Students love this hands-on science experiment that illustrates how energy can transfer between objects. It is an age-old classic that helps children understand Newton’s third law of motion.
Kids can explore additional variables by altering the track and measuring velocity to calculate GPE, KE, and force. They may also use this activity as an avenue for explaining trajectory.
