Depending on where you live, this time of year the ground might be covered in snow, ice, and most importantly – pinecones! We see pinecones everywhere during the winter, in wreaths, on trees, and in our yards, but did you know that pinecones have a vital job – they keep pine tree seeds safe, and protect them from the freezing temperatures during the winter! To protect their precious seeds, pinecones can close their ‘scales’ tightly, keeping out cold temperatures, winds,… Read more

Upstairs, Downstairs: Turning on a Light from Two Places

Science Fair Project Idea

Scientific Method

Maybe somewhere in your home there's a long hallway or a stairway with a light that you can turn on from either end. It's a nice convenience, but did you ever wonder how it's wired up to work that way? The goal of this project is to build a similar circuit with switches, flashlight batteries and a flashlight bulb (obviously, household circuits are not safe to experiment with). You'll need to understand the difference between connections made in series and connections made in parallel in an… Read more

You are probably used to seeing things float, be it a boat on the water, or a rubber duck in your bathtub. But did you ever wonder how the same water that you drink, splash, and dive into – how can that support the weight of giant boats? In this activity we’ll learn about surface tension and how it helps us keep afloat! Read more

Using AI to Detect Proper Exercise Form

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how Artificial Intelligence (AI) can be used to improve human health and medicine? Computers can now identify human joints as key points to track our body movements. They can then use this information along with training data sets to show us if we perform exercises safely, to prevent us from getting injured. Create your own data set and test out if your algorithm can reliably detect good and bad exercise form. Read more

Using Synthetic DNA as a Secret Barcode

Science Fair Project Idea

Scientific Method

How would you secretly mark a bank robber during a robbery? What could you do to ensure that the ethically grown cotton you grew and shipped off for weaving and garment making was used to make the shipment of shirts you received weeks later? When we want to tag and track something, we often use a barcode. From grocery store foods to FedEx packages, barcodes are a way of tagging and identifying items. The fact that barcodes can be unique and are easy to read are key features. Not all things… Read more

Science Fair Project Idea

Scientific Method

Here's a cool project that shows you how to use images from an orbiting observatory to measure how fast the Sun rotates. Read more

Using Weather Balloon Data to Map Atmospheric Temperature

Science Fair Project Idea

Scientific Method

Snow-capped mountains make a picturesque scene, especially in summertime when the peaks are in such contrast to the warmth below. This project shows you a way to see how temperature changes with altitude using data collected twice daily from weather balloons. Read more

If you pour water into a clear glass, what color is it? It’s clear, right? But what happens if you try to look through it to see the world on the other side of the glass? It looks a little distorted, maybe a little fuzzier and uneven. If water is clear, why can’t we see through it clearly? The answer has to do with how light moves through water, glass, and other transparent materials. Just like when you try to run in a swimming pool, when light tries to move through water or glass,… Read more
