Smarter Farming with Aerial Photo Analysis

Science Fair Project Idea

Scientific Method

Wondering what sustainable, high-producing agriculture might look like? This science project explores how analyzing bird's-eye-view pictures of a field can make farmers aware of variations in their fields. Farmers can use this information to optimize their farming practices, or even feed this information to high-tech agricultural equipment so the machines can automatically adjust their actions (like fertilizing or watering) to the needs of a piece of land.

I See a Full Moon Rising...and Shrinking...or Do I?

Science Fair Project Idea

Scientific Method

Have you ever noticed how the moon appears bigger at the horizon, just as it is rising over the treetops, than it does later in the evening when it is overhead? Of course, the size of the moon does not change, but our perception of its size changes based on where it is in the sky. In this human biology science fair project, you will investigate Emmert's law, which explains the full moon illusion. You will estimate the size of the perceived increase in the size of the moon at the horizon. Read more

Expression Cloning

Science Fair Project Idea

Scientific Method

What is expression cloning and how is it used in the biotechnology industry? How are plasmids constructed for use in a bacterial expression system? You can investigate these questions and more using bacterial expression kits meant for high school classes. You will need a laboratory space equipped to grow bacteria and carry out simple molecular biology. A kit with plasmids and bacterial cells to transform are also needed. Here are two possibilities: BioBuilder What a Colorful World Kit … Read more

Create and View Your Own 3D Models in Virtual Reality

Science Fair Project Idea

Engineering Design Process

Virtual reality (VR) headsets are becoming increasingly popular. Video game designers use a variety of programs to create the amazing 3D worlds that you see when you turn on your favorite video game, and many of those worlds are now also designed to be compatible with VR headsets. Can you use a computer-aided design (CAD) program or video game engine to design your own virtual world that can be viewed using a VR headset? Table 1 lists several CAD programs and websites that you can use to make… Read more

Designing an AI Agent for Expense Tracking

Science Fair Project Idea

Engineering Design Process

Do you have a hard time keeping track of how much money you spend? What if you could automate the task somehow? In this project, you will explore how to use ChatGPT’s Agent mode to create an expense tracker spreadsheet. Read more

Solving Logic Problems

Science Fair Project Idea

Scientific Method

You may know Lewis Carroll as the author of Alice in Wonderland, but did you know that in real life he was a mathematician who studied symbolic logic and logical reasoning? How can math help you solve Lewis Carroll's Logic Game? (Bogomolny, 2006) How are algorithms for solving the game Sudoku similar to solving a logic problem? (Hayes, 2006) For the super-advanced mathematical genius, try to evaluate currently available, logic-based computational tools, or design a better one!… Read more

Get Some Practice at 'Fossil' Reconstruction with Owl Pellets

Science Fair Project Idea

Scientific Method

Are you fascinated by dinosaurs, fossilized bones, and fossilized plants? Although this project is not based on actual fossils, you will get good practice at reconstructing an animal's skeleton from individual bones. You'll use what you find to identify the types of prey that owls consume. Read more

Build a Solar-Tracking Robot

Science Fair Project Idea

Scientific Method

Light sensors are part of many devices that we use every day. For example, they help your phone know when to automatically brighten or dim the screen based on ambient light levels. They can also be used to help solar panels track the sun, which helps the panels generate more power. Many spacecraft and planetary rovers are solar-powered. In this project you will build and program your own solar-tracking robot. Optionally, you can add solar panels and rechargeable batteries. Can your robot keep… Read more

Deforestation

Science Fair Project Idea

Scientific Method

The conversion of forested to unforested areas has been occurring since humans began to impact and change their environments during the agricultural revolution. Recently deforestation has become a global problem, particularly for developing industrial countries and countries with very large populations. You can use satellite mapping resources to investigate the connection between urbanization, population growth and deforestation. You can also investigate the connection between deforestation… Read more

Wind Speed

Science Fair Project Idea

Scientific Method

Wind can make a cold day colder, or a hot day more pleasant. Use weather data to test the effect of wind on the temperature. How much of a change on the perceived temperature can the wind make? How is wind shear calculated? How can a wind barrier, like a wind breaker, keep you warm even if there is no insulating material? Build an instrument to measure wind speed or direction. (FI, 2006; GLOBE, 2006; NCAR, 2006; NOAA, 2006; Unisys, 2006; Weather Underground, 2006; WMO, 2006) Read more
