Tiling with Spidrons

Science Fair Project Idea

Scientific Method

This is a great science fair project for someone who is interested in both mathematics and art. Spidrons are geometric forms made from alternating sequences of equilateral and isosceles (30°, 30°, 120°) triangles. Spidrons were discovered and named by Daniel Erdély in the early 1970's, and have since been studied by mathematicians and artists alike. This project is a great way to learn about the mathematics and art of tiling patterns. Read more

Topologies

Science Fair Project Idea

Scientific Method

What do knots, maps, mazes, driving directions, and doughnuts have in common? The answer is topology, a branch of mathematics that studies the spatial properties and connections of an object. Topology has sometimes been called rubber-sheet geometry because it does not distinguish between a circle and a square (a circle made out of a rubber band can be stretched into a square) but does distinguish between a circle and a figure eight (you cannot stretch a figure eight into a circle without… Read more

Tracking Geomagnetic Storms in the Ionosphere

Science Fair Project Idea

Scientific Method

The Sun is the ultimate source of the energy that powers weather systems on Earth. Geomagnetic storms are sun-powered storms in the upper atmosphere, arising from energized particles that are periodically ejected by the Sun. Among other effects, geomagnetic storms can wreak havoc with earth-orbiting satellites, and disrupt satellite communications. The global positioning system (GPS) is a network of 24 earth-orbiting satellites that constantly sends radio signals through the earth's… Read more

Two-Point and Four-Point Methods for Measuring Small Resistances

Science Fair Project Idea

Scientific Method

Measuring the value of a resistor with a multimeter is pretty simple. You set the multimeter to measure resistance, connect the two leads to the resistor (possibly using some handy alligator clips), and read the resistance value. This is called a two-point measurement (one probe on each of the two resistor leads). But what if the resistance you want to measure is very small, in the milli or micro-ohm (mΩ or μΩ) range? This can introduce problems because many low-cost multimeters… Read more

Underground Water Flow and Darcy's Law

Science Fair Project Idea

Scientific Method

This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and cave formation. With your model system, you can simulate various underground conditions, and test your predictions about the effects they have on water flow. Read more

Using a Magnet as an Electrical Current Detector

Science Fair Project Idea

Scientific Method

An electric current produces a magnetic field. You can take advantage of this fact to make a simple apparatus to test the electrical conductivity of various materials, including both solids and liquids. The detector consists of a coil of wire, with a magnetic compass inside it. You connect one end of the coil to a D-cell battery. The other end of the coil is connected to whatever material you are testing, and the material, in turn, is connected to the other end of the D-cell. In other… Read more

Using the Solar & Heliospheric Observatory Satellite (SOHO) to Determine the Rotation of the Sun

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

Water is one of the most important resources for life. Here on Earth, we often take it for granted — we can easily get a glass of water from the tap whenever we’re thirsty. But imagine being an astronaut orbiting hundreds of miles above our planet. In space, every drop of water is precious, and there’s no tap to turn on. Transporting water from Earth to the ISS is incredibly expensive and impractical due to the limited cargo space and the high cost of launching supplies. To address this,… Read more

Wearables are found all over the biomedical world: heart rate monitors, EKG patches, braces, etc. In this project, you will make your own wearable air quality sensor that notifies you of high-risk air. You can attach the sensor patch on any existing clothing or even make a standalone patch that you can wear as a necklace or a bracelet. Read more

Sewable circuits are a fun way to mix electronics and arts and crafts by sewing circuits into clothing or fabric. This sewable circuit focuses on creating a unicorn horn with a programmable red-green-blue (RGB) LED in the tip that changes colors. You will use conductive thread to make the circuit, but your stitched lines will also form the spiral lines of the unicorn horn. Read more
