The science fair is an excellent place for those curious about our world\u2019s composition to demonstrate their educational prowess for others to enjoy. However, it can also be quite daunting for someone who may not know where to start or what would navigate that middle ground between a passionate subject and a physical construction in said area of expertise.<\/span><\/p>\n

Where can one find ideas for this task? No worries, we\u2019ve got you covered. Here are five ideas to get you thinking about what you\u2019re looking for in a science fair project! If none of these catch your fancy, they were all taken from<\/span> ScienceBuddies.org<\/span><\/a>, and there are plenty more experiments to choose from if you feel obliged to give them a look.<\/span><\/p>\n

 <\/p>\n

\u00a01. Extracting DNA from Strawberries<\/strong><\/h2>\n

Link to Project: <\/span>https:\/\/www.sciencebuddies.org\/science-fair-projects\/project-ideas\/BioChem_p015\/biotechnology-techniques\/strawberry-dna<\/span><\/a><\/p>\n

Let\u2019s get down to the basics, such as DNA. There isn\u2019t much to be said about DNA that hasn\u2019t been extensively researched, but that\u2019s also why it is a great project to work with. This example is simple and cost-effective but allows students to become a biotechnological engineer for a day and condense a strawberry into its purest form: its genetic composition.<\/span><\/p>\n

To simplify the process so that the average person (or blog writer) would understand it, you use a chemical (dishwashing liquid, so nothing dangerous) to crack the cells open. Then, you attract the DNA with salt to group close to one another, and you separate the whole mixture with rubbing alcohol to show your audience what the biological instructions (DNA) for creating strawberries look like! It’s relatively easy but still pretty cool.<\/span><\/p>\n

2. Musical Straws<\/b><\/h2>\n

Link to Project: <\/span>https:\/\/www.sciencebuddies.org\/science-fair-projects\/project-ideas\/Music_p016\/music\/do-re-mi-with-straws<\/span><\/a><\/p>\n

Music is something that everyone inherently understands, but only some ever try to comprehend. How does good noise come from wooden and metal sticks, like clarinets and flutes? Sounds like the perfect idea for a science fair project! In this experiment, the student doesn\u2019t need much more than the materials they likely already have at home: straws, a tape measure, and some sort of tuning app or musical instrument.<\/span><\/p>\n

This project entails cutting the straws into a roughly \u201creed\u201d shape, similar to the device an oboe uses to create its distinct timbre, and snipping off the other end to produce differing pitches of said instrument. While simple in theory, in concept, it can be pretty tricky to find exactly the perfect note, and if you\u2019re off by a couple of cents, the band kids will likely notice! This project would pair well with some graphs explaining how sound travels through the air in wavelengths, with the straws acting as a visual aid rather than the explanation itself.<\/span><\/p>\n

3. Homemade Wind Meter<\/b><\/h2>\n

Link to Project: <\/span>https:\/\/www.sciencebuddies.org\/science-fair-projects\/project-ideas\/Weather_p008\/weather-atmosphere\/how-does-a-wind-meter-work<\/span><\/a><\/p>\n

Those weather forecasts\u2026one moment, they tell you it\u2019s sunny, and next thing you know, you\u2019re knee-deep in rainwater. With this experiment, you can be wrong about the weather, too! (or right, preferably).<\/span><\/p>\n

Anemometers are measuring devices that meteorologists use to measure wind speed, and surprisingly, they\u2019re not that complicated. For this experiment, you\u2019d need the standard office supplies (scissors, stapler, pencil, etc.) with some paper cups, straws (which is, let\u2019s face it, the most versatile DIY material out there), a pin, and a fan with different speeds. Following the instructions on the website will grant you a homemade anemometer of your own, and once you add in a description of wind\u2019s role in the formation of weather, you\u2019re set to go for this week\u2019s science fair!<\/span><\/p>\n

4. Recognizing Faces with Neural Networks<\/b><\/h2>\n

Link to Project: <\/span>https:\/\/www.sciencebuddies.org\/science-fair-projects\/project-ideas\/ArtificialIntelligence_p016\/artificial-intelligence\/facial_recognition<\/span><\/a><\/p>\n

Recognizing faces is something that most humans innately do instinctively, but it\u2019s a whole different story regarding computers. It takes a ton of software, hardware, and lots of years in college to get your laptop to differentiate different humans by appearance\u2026right?<\/span><\/p>\n

Apparently not, because it\u2019s on this list of high-school science fair ideas! While there is more prep work than previously mentioned projects, it\u2019s fairly technical but straightforward.<\/span><\/p>\n

The simplest explanation is this: You\u2019ll take a bunch of pictures from person A and tell the machine, ” This is the person I want,\u201d designating one as an \u201canchor image.\u201d The machine will take this \u201canchor image\u201d and these \u201cpositive images\u201d and note the details that make up the person\u2019s face (e.g., \u201cthey have a mole on their left cheek\u201d or \u201ctheir eyes are always blue\u201d).<\/span><\/p>\n

Then, you\u2019ll continuously show it \u201cnegative images,\u201d pictures of person B, C, D, and so on, and tell it, \u201cThis is not the person I want.\u201d With each pass, you\u2019ll train it to identify the person you want and the people you don\u2019t want until this computer can reliably tell you from any picture of a human that \u201cthe picture is\/is not person A.\u201d<\/span><\/p>\n

ScienceBuddies.org provides a more in-depth explanation for this process, but what can be certain is that this is a worthwhile project to explore for any computer geeks out there.<\/span><\/p>\n

5. DIY Phonograph<\/b><\/h2>\n

Link to Project: <\/span>https:\/\/www.sciencebuddies.org\/science-fair-projects\/project-ideas\/Music_p032\/music\/make-a-phonograph<\/span><\/a><\/p>\n

This project is likely the most physically complex, and for that, it\u2019s the last on this list. The student will need tin cans, aluminum foil, rubber bands, sewing needles, scotch tape, latex balloons, scissors, and a plastic funnel. Here\u2019s the kicker: three volunteers and a turntable or lazy Susan will be needed. These can be hard to find, so ensure you can acquire them head-on before entering this project.<\/span><\/p>\n

The overall concept is that you can remove the tops and bottoms of the cans and keep the balloon (or foil, as it is an alternative material) on one end with the rubber bands and the needle taped an inch from the edge of the balloon\/foil side. Then, someone will rotate the lazy Susan or turntable with a record on top, the needle of the can sticking into one of the ridges of the record, and you\u2019ll record the sound quality for each can combination.<\/span><\/p>\n

This project provides an exemplary view of the different parts that play into a phonograph and how it operates. It\u2019s a great visual and auditory aid. Hearing the differences in action will definitely surprise other participants and the audience!<\/span><\/p>\n

\u00a0<\/span><\/p>\n

There are many ways to go about creating something for a science fair. As shown above, they come in all shapes and sizes, difficulties and costs. But at the end of the day, every teacher can attest that what matters is that the students learn something and have fun while doing it! Hopefully, these ideas can spur an excitement for an exciting field of study that\u2019ll push forward long after a science fair. If not, then a fun little experiment will have to do. Either way, something of value will have been gained; that much is guaranteed.<\/span><\/p>\n
