This experiment combines math and biology to measure lung capacity using a balloon. Learn more: Steve Spangler Science/Magic Traveling Flame 10. Tell students you’re going to relight a candle without touching the flame to the wick. While you’ve got the candles out, try this demonstration. (Don’t be afraid of fire in the science classroom! Here’s why you should try it. Take it a step further by experimenting with the carbon dioxide it produces. Blow out a candle with a balloonīlowing up a balloon with baking soda and vinegar is the classic acids and bases experiment. Follow the directions at the link to build one, or challenge eighth grade science students to experiment with their own construction methods. Newton’s cradle is a fascinating way of demonstrating momentum and energy transfer. Learn more: Steve Spangler Science/Egg Drop Inertia Trick 7. (Worried about making a mess? Use plastic eggs instead.) When you knock the pie tin out of the way, the egg falls straight into the glass, thanks to inertia. This experiment looks like a magic trick, but it’s firmly grounded in Newton’s First Law of Motion. Drop an egg to prove the first law of motion
In this experiment, students will see its effects first hand and brainstorm ways to keep it in check. Measure algae growthįertilizer runoff has become a serious cause of water pollution. Learn more: Science Buddies/Electrolytes 5. You’ll need a few special supplies, like a multimeter and an Ohm resistor, but they’re inexpensive and easy to find. Compare them with water or orange juice for a cool science fair project. Sports-loving kids will enjoy the chance to learn just how many valuable electrolytes their favorite sports drinks contain. Can they build a hand that can pick up a ball? How about one that can pluck up a piece of string? So many possibilities! Or encourage them to think of ways they can improve upon the design. Challenge your students to make the model as shown at the link. This is a project that can be tweaked in a variety of ways. Learn more: 123Homeschool4Me/Build a Lightbulb 3. Then, turn it into an eighth grade science fair experiment by tinkering with the various materials to make a lightbulb that lasts longer, burns brighter, or is powered by an alternative source. Build a better lightbulbįirst, use the steps at the link to build a simple lightbulb with a jar, some wire, and a 6-volt battery. Next, place one soda in the fridge, one in the freezer, one in the ice bath and one in the ice water bath and continuously check their temperatures to see which method cools the soda the quickest.In this experiment, kids water plants with different liquids, like rainwater, tap water, saltwater, and even soda. You will then need to make a water bath and an ice water bath and then check the temperature of the soda before you start. For this project you will need a digital thermometer, water, ice, a refrigerator, four cans of soda, a timer, plastic wrap and two Styrofoam coolers.
You could do some research and see how effective they really are.Īnother good physics project would be to see which method will cool a soda the quickest from room temperature. Some people believe they help with headaches, joint pain or back pain. If magnets interest you, a good science fair project might be to see if magnetic bracelets and necklaces can really help with pain in your body.
Maybe you are interested in machines and how they work, or how magnets work. There are still many aspects of our world and our universe that we don't completely understand, so thinking of a topic for your project is just a matter of thinking of a question you have about our world whether it be wondering how electricity works, or energy, or studying gravity. There are many different projects that can be done about physics because physics covers a very broad range of subjects. Studying these topics will give us a better understanding of how the world and the universe around us work. Physics science fair projects are based on the study of matter and energy and focus on understanding electricity, energy, gravity, machines, magnets, and how certain materials change and combine.
