Volunteers can touch tracing paper that’s been heavily scribbled on with pencil.
The funnel and straw will empty into a waiting cup. Use the heavy washers on top of the cling wrap to guide droplets of evaporated water down a gentle slope into the funnel. Cling wrap will cover the containers to collect evaporation. Containers of saltwater placed in the sunshine will begin to evaporate. Collect this desalinated water with a simple DIY contraption. When ocean water evaporates, the salt is left behind. Image by Comfreak from Pixabay How it’s done: Can We Distill Saltwater With Solar Power? Materials: Check out this optical illusion in greater detail! 5. The visual trickery lies in the mirrored window cling viewing window. LED bulbs are inserted through holes in the walls of the box. Use adhesive to secure the mirror to the floor of the box. Mirror, mirror on the wall – Are you a mirror or a never-ending hall? Your student will create an optical illusion with some inexpensive and basic supplies. Create an Optical Illusion With an Infinity Mirror Materials: Read more about why this science project works the way it does! 4. Students can even weigh the meat before/after the experiment to include quantitative data along with their visual observations. Image by PDPhotos from Pixabay How it’s done:ĭid you know soda has a similar pH level to the human stomach? So soda should be able to digest meat as our stomachs do, right? To test this hypothesis, place each different meat into a container and cover it completely with soda. What Effects Do Carbonated Drinks Have on Meat? Materials: Expanding gases will inflate the balloons that have been stretched over the opening of the bottle, visually illustrating which beverage releases the most gas! 3. One of the properties of gas states that gases expand to fill their container. Placing the bottles on a heating pad will speed up this “mock digestion”. When is a balloon actually a belch? In this project of course! Pour equal amounts of different beverages into individual bottles and add vinegar (to act like our stomach acids).

Did your volunteers stay cool under pressure? How did stress affect their temperature regulation? 2.

Have your volunteers perform a timed math test or a series of difficult puzzles. This project could illustrate why your student literally sweats that math test every week. Image by HeungSoon from Pixabay How it’s done:
How Does Stress Affect Body Temperature? Materials: Being interested in the outcome (conclusion) of their own project is an important part of getting them to do the work willingly rather than begrudgingly.Ĭheck out some of the best 8th-grade science fair projects we’ve found to get your budding researcher’s wheels moving! (And don’t forget your trusty lab notebook to record methods and observations!): 1. Your rookie scientist just needs to find a question (hypothesis) that they really want to answer. Hark! Fear not brave parents, for choosing an 8th-grade science project doesn’t need to be scary or overly complicated. The hardest part for most middle-school students is selecting age-appropriate science experiments that can be completed independently. The scope of the project is enough to make your head spin if this isn’t something you’ve already done with them in 7th grade. The teacher has given them a lengthy rubric outlining all the requirements and presentation methods their assignment must adhere to. Your eighth-grader brought home an assignment that can strike fear into the hearts of parents everywhere. 8th Grade Science Fair Projects – Don’t make it harder than it has to be!
