No matter if it’s their first science fair in elementary school or competing at national levels, your children can participate in exciting science experiments! From easy projects that teach science concepts and are entertaining to complicated experiments that push their knowledge further afield – there’s sure to be something they enjoy doing that fits this bill!
Discover gravity and kinetic energy with this classic seventh grade science project, which requires just a few supplies but promises stunning results that are sure to dazzle any audience!
1. Oxidation Experiment
Oxidation is responsible for turning apples brown and pennies dull – two concepts at the core of some fascinating science experiments.
This fascinating chemistry experiment uses vinegar as a household acid to clean copper pennies. Simply collect several dull pennies, place them in a non-metal bowl with either water, salt or vinegar and observe. Alter the conditions as necessary and note any effects or changes on rusting rates or prevention! Make this project even more engaging by changing any conditions to see how rust can be delayed or prevented!
2. Battle Tops
If your children like tinkering, these exciting science fair projects are sure to get them thinking and learning! From angular momentum, friction and centrifugal force – to heat transfer.
Ideal created the Battle Tops tournament-style game in 1968 to allow two to four players to launch spinning battle tops into a ring and battle it out until only one remains standing and wins the round.
This easy science experiment is perfect for kids who enjoy fiddling with chemicals. Just combine water, soap and glycerin in a beaker before dipping a straw into the solution to create bubbles on a plate.
Encourage children to observe and discuss the vibrant hues and explore how they might manipulate a bubble without popping it. Discuss strategies for manipulating it without breaking it!
Explain that bubbles thrive in moisture; dry hands tend to deflate them quickly while wet hands help them hold on longer.
4. Lip Balm
Tinted lip balm can give lips an elegant splash of color or simply provide natural protection, and these soft wax-like substances offer excellent occlusive properties to safeguard skin on lips. In this cosmetic science project, students develop their own recipe for homemade lip balm before testing quantitatively against customer preferences and measuring costumer feedback.
Learn physics and engineering through this Rube Goldberg machine!
5. Sidewalk Chalk
Children enjoy using sidewalk chalk, and this fun experiment teaches them about nucleation. Because it will get messy quickly, an outdoor location should be selected.
Draw a crisscross pattern using tape on a patio, driveway or sidewalk and fill each section with different colored chalk. Children can then hop through the numbers and test their balance, coordination and endurance.
Shadow sidewalk chalk art teaches kids about shadow formation, while their custom sundial can help them learn about its movement throughout the day.
6. Light Bulb
Light bulbs serve many functions. They provide illumination for an entire room, indicate when an electronic device has powered on and even serve to heat homes.
The bulb works by transmitting electricity through a long, twisting length of curly tungsten metal wire, heating it and creating a glow effect.
Try this experiment and see if you can make your lightbulb glow for as long as possible! Just remember to use caution when dealing with electrical wire and batteries.
No matter their grade level or competition level, kids need an engaging science fair project idea to take home. Such ideas help children build vital STEM skills such as asking questions, formulating hypotheses and conducting tests.
Discover why eggs float or sink using this fun and engaging home experiment designed for seventh grade science students.
8. Climate Change
Demonstrate the greenhouse effect with a straightforward experiment using just a jar and thermometer. Watch how air in an enclosed jar warms faster than air in an unprotected one – showing why global warming poses such a serious threat to society.
Turn a classic baking soda and vinegar volcano into an easy science fair project by exploring what factors affect its chemical reaction. Also explore osmosis and capillary action with this STEAMsational project!
9. Density Experiment
Density is a measure of matter in an object or substance. With this fun science experiment, children can explore what density means as objects sink or float through liquid.
Kids can build a tower to demonstrate how less dense substances create its base while more dense ones make up its top layers. This experiment helps explain why objects sink in salt water but float in fresh water.
10. Sports Drinks
Students studying nutrition may want to investigate the electrolytes present in sports drinks and compare them with water for an impressive science fair project idea that also explores chemistry concepts. This experiment is sure to impress judges!
Are introverts more likely to have good memories? Discover it with this intriguing science project from Science Fair Extravaganza.
Make this experiment part of their science lessons to teach them about atoms and density! Additionally, use it as an opportunity for fun learning experiences!
