Science Fair Project Idea

Scientific Method

Imagine yourself as a software engineer, a decade and a half from now. You are called upon to help solve the world energy crisis by programming nano-organisms (NANORGs) to extract energy from industrial sludge. Your program must be small enough to fit in the NANORGs' tiny processors, yet at the same time meet several challenges. First and foremost, your NANORGs need to navigate on their own, extract energy from the sludge, and find collection points to deliver the harvested energy. Second,… Read more

You might have read about the negative impacts modern human civilization has had on the environment, like pollution, deforestation, and extinction of animal species. How can we use modern technology to help protect the environment? In this project-based lesson students will design an electronic circuit that can measure something in the environment like water quality and light pollution, and develop a plan for how their circuits could be used to solve a real-world problem.

HS-ESS3-4. Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

Purification Strategies

Science Fair Project Idea

Scientific Method

In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project Extracting Onion DNA). The source of the material can be a cell… Read more

Relationships Between Variables: Using Correlation and Linear Regression

Science Fair Project Idea

Scientific Method

Here's a project that combines sports and math. You'll learn how to use correlation analysis to choose the best team batting statistic for predicting run-scoring ability (Albert, 2003). You'll also learn how to use a spreadsheet to measure correlations between two variables. The project description Which Team Batting Statistic Predicts Run Production Best? provides the details.

Silt Deposits in Streams

Science Fair Project Idea

Scientific Method

Silt is a fine sediment that collects on the bottoms of rivers, streams and lakes. The natural process of the decay of organisms into the water can lead to the production of silt at the bottom of a lake. Silt can be a rich source of nutrients for fish and bottom dwellers like crayfish. However, it can also be introduced by unnatural processes. One problem for rivers, lakes and streams is the buildup of excess fine sediment introduced by industry. Because it often contains harmful chemicals it… Read more

Skating and Angular Momentum

Science Fair Project Idea

Scientific Method

Place a desk chair (one that rotates easily on ball bearings) in the center of the room, away from any obstructions. Put your hands on your lap and have a helper give you a push to start you rotating. You'll need to quantify the results somehow. For example, your helper could measure the number of revolutions you make in 5 seconds. Now try extending your arms after your helper starts you spinning. Next, start with your arms out, and bring them in close to your body after you start… Read more

Slimey Likes It! Studying Chemotaxis in Physarum Polycephalum

Science Fair Project Idea

Scientific Method

In this biology science fair project, you will observe how the Physarum polycephalum (P. polycephalum) organism responds to various amounts of glucose. P. polycephalum is easy to grow in a petri dish and responds in complex ways to its environment. Will it grow toward the chemical as it looks for a meal, or will it flee, trying to avoid further contact? Try this science fair project to learn more about chemotaxis in the fascinating Physarum polycephalum. Read more
