If you decide to use any of these ideas for your own project, be sure to take some photos and show off your results over in the Inspiration section! Know of an awesome investigatory project that's not on the list, like wireless electricity or cheaper x-ray machines? Let us know in the comments below. Once you've built your batteries, hook up a volt meter to read the output and see which one is the best. Pick a few different fruits or vegetables and form a hypothesis as to which will make the battery that puts out the most energy or lasts the longest. So what's the investigation consist of?Ĭan you truly affect the way you act and feel by simply changing your posture? Does acting a certain way manipulate the mind drastically enough to actually change the way you feel?Ĭheck out Amy Cuddy's awesome TED Talk for more ideas for additional questions you could ask. The science of the mind can be just as interesting. Science experiments don't always have to include chemicals or test tubes. Project #13: Improving Social Anxiety by Manipulating the Body & Mind Come up with your own theory and let the brain hacking begin. This article contends that memory can be improved by looking at NSFW images or thinking of dirty associations. Does using colors to form associations help with memory? Does linking an image with a memory increase its hold in the carrier's head? What about drinking grape juice or sniffing rosemary? These are the types of questions you may look to answer. But for your investigatory science project, you will want to come up with your own hypothesis based on that information and test it out. There are tons of studies on memory and memory loss that you can research. Project #1: Making Soap Out of Guavaīasic hygiene should be available to everyone, but what about people who live in areas without easy access to grocery stores or pharmacies? This is a great question that makes you think about scientific alternatives to store-bought soap.īelow is an example project that creates soap from guava leaf extract and sodium hydroxide, but there's no shortage of materials you can use to replace the guava, like coconut oil or a fat like lard, butter or even the grease from your kitchen. I've listed a few examples below of some of the best investigatory experiments out there, so hopefully you'll have no problem coming up with an idea. The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be. In order to conduct a great investigatory experiment, you have to ask an interesting question and be able to conduct an experiment that can hopefully answer that question. What Kind of Investigatory Projects Are There? The purpose of these projects is to think critically, and if the solution doesn't work out, that doesn't mean your project will fail. Remember, however, that a successful investigatory science project does not necessarily have to result in the intended outcome.
