Science Fair Experiments for upper gradersWebsites with experiment ideas include:1 , : search grade level3.. . cockroaches have a preference for direction? Catch and release cockroaches. Which way do they go? Is there a common trend or not? You can try this project with ants or other crawling insects.?Do colored ice cubes melt at the same rate as clear ice cubes? Add food coloring to an ice cube tray and compare how long the colored cubes take to melt compared with the regular ones.?Does magnetism travel through all materials? Put different materials between a magnet and metal. Do they affect how strongly the magnet is attracted to the metal? If so, do they all affect the magnetic field the same amount??Do all crayon colors last the same? Draw a really long line with one color, draw the same length of line with another color. Are both crayons the same length?Will seeds germinate if you soak them in a liquid other than water? You can try milk, juice, vinegar, and other common household liquids. Alternatively, you could see if plants will grow if they are 'watered' with liquids other than water.?How much salt (or sugar) can a plant tolerate? Water plants with different solution of salt or sugar. How high of a concentration can the plant tolerate? A related question would be to see if plants can survive if they are watered with soapy water, like leftover dishwater.?Do birds have a preference for birdhouse material? In other words, do they seem to care if the birdhouse is made from wood or plastic or metal??Do worms react when exposed to light? Do worms react differently to different colors of light??Do ants prefer different types of sugar? Different types of sugar are found in table sugar, honey, maple syrup, and molasses.?Can you taste the difference between foods that contain fat and fat-free versions of the same product??Do white candles and colored candles burn at the same rate?6. teachers search 40 cool science experiments1.

Use this quick video lesson to teach your students about the density of air and how it is affected by changes in temperature.16. How to Make a Miniature VolcanoSome teachers see the vinegar and baking soda volcano as something of a science fair cliché. It may be an oldie, but it's a still a goodie. Watch this with your students before creating your own mini Krakatoas.17. Exploding Pi?atas Watch seventh- and eighth-graders design a pi?ata that explodes on its own and sprays the room with candy. A good model of the scientific process-students come up with the goals of their experiments and test several models to determine success.18. The Science of Solids, Liquids, and GasesUsing ingredients readily available at grocery, drug, and hardware stores, children can learn about the properties of matter.19. How to Make a CO2 SandwichHere's a fun activity that uses some common items that you'll find around the house and a little creativity to explore the "pop" factor of vinegar and baking soda. Steve Spangler and his second-grade assistants create "sandwich bombs" out of plastic bags and simple chemistry.20. How Does Your Body Digest Food?In this video, Marshall Brain dives into the digestive process and presents an experiment that replicates how the stomach and large and small intestines break down food.21. Exploding Bubbles What happens when heat is applied to bubbles created using hydrogen gas? The video experiment starts slow but ends with a bang.22. The Science of Remote ControlsYour students use them all the time, but do they know how they work? Pushing a button on a remote control sets in motion a series of events that causes the device to send out a pattern of light pulses. The infrared sensor on the controlled device "reads" these pulses. The Happy Scientist explains how and why it works.23. How to Make a Glacier Out of GAK Elmer's glue, Borax, and a few other ingredients are used to demonstrate the properties of an arctic glacier. Both GAK and glaciers are polymers that can stretch or break depending on the amount of pressure applied. If there is a lot of pressure on a glacier, ice will crack or break (causing crevasses in glaciers); when the pressure is lower or the strain rate is small and constant, ice can bend.24. The Electric PickleAnother super demonstration from Steve Spangler, this amusing and highly informative experiment uses a pickle in a simple electric circuit. Your students will light up when the pickle turns red and glows! A great introduction to the science of electricity.25. How to Make a Tornado in a BottleWith simple ingredients, students can create a miniature whirlpool that illustrates the movement and behavior of water with artistic flair.26.

The Sticky Note ExperimentsThis smart, funny video will teach you and your students how to make a "waterfall" out of sticky notes. The video is entirely without words and only about a minute long, but it will inspire your students to want to make their own experiment videos. (Tip: Share the videos at your next science fair.)30. A Watched PotHow much science can you learn by watching a pot of boiling water? You and your students might be surprised. Learn how heat affects water's density and why bubbles float to the top.31. How to Build a CatapultOne of the most basic physics projects around is also one of the most enjoyable. Colin Kilbane teaches viewers how to make a tiny, very simple machine. Building a catapult is simple: Use a block of wood as a base, a plastic spoon as the arm, and two push pins and a rubber band as the torsion energy. What's your ammunition? Mini marshmallows, of course.32. Light Bends and BouncesThe science videos of Bill Nye the Science Guy are produced by Disney and couldn't be clearer or more appealing to students. Do your students know why light bends through a lens? Bill shows us why. Notice that the light changes direction every time it goes from air to plastic, and then again when it goes from plastic to air. It slows down and speeds up. When that happens, it just can't help but bend.33. What Happens When You Mix Diet Coke and Mentos?The scientists test their theories on why soda turns into a fountain if you drop in a Mento. Show this to students after trying the experiment and challenge them to propose their own theories.34. How to Walk on WaterThis extremely messy experiment is an argument in itself for using video in your classroom. A mixture of cornstarch and water teaches kids about non-Newtonian fluids while at the same time shows them how to walk on it without sinking.35. What is Energy?Bill Nye introduces the concept of energy with his kinetic style, a bowling ball, a piece of glass, and a barbecue. Energy can change from one form to another. Watch as it makes things go, run, and happen.36. Are Elephants Afraid of Mice?The Mythbusters investigate the truth behind the old tale of whether mighty pachyderms are afraid of tiny rodents. The results might surprise you!37. How to Make ButterShow your students this video hosted by the always pleasant Robert Klampf before having them make their own butter from soured cream.38. Feel the PressurePressure pushes in all directions at once. Bill Nye goes scuba diving and journeys to the Hoover Dam with a jackhammer to demonstrate the concept of underwater pressure.39. The Egg and the BottleSteve Spangler offers up a new perspective on the tried-and-true classic experiments in which a hard-boiled egg pops into a bottle when the bottle is heated. Why does it work? When molecules of air heat up, they move far away from each other and take up more space.40. Bowling and MomentumTo explain the concept of momentum, Bill Nye shows the universal forces at work in the difference between throwing a ping-pong ball and a bowling ball at the pins. ................
