Find the Best Place to Put a Solar Panel

Science Fair Project Idea

Scientific Method

Imagine trying to put a solar panel on your roof or outside your home to generate clean, renewable energy. Where would you put it so it generates as much power as possible throughout the day? What direction should it face? Is there a way to take measurements to find the best location before you install the panel? In this project, you will use a tiny programmable device called a micro:bit to record light data and find the best place to put your panel. Read more

Flash Floods

Science Fair Project Idea

Scientific Method

You can investigate how the geography of an area makes it prone to severe flash floods. Some areas, typically gullies or canyons, can flood extremely rapidly making it impossible to escape a flash flood. Compare the topography, or geographical shape, or these areas. What makes them prone to flash floods? Can you do an experiment showing how the flow of water increases as a channel narrows? Can you use topological maps of your region to identify areas at risk for flash floods? (NCAR, 2006;… Read more

Have you ever wondered how a decision to move your arm can make your arm move? When your brain creates a command to move your arm, nerves pass along the command and muscles in the arm contract as ordered. These muscle contractions make your arm move. But could your arm move without a command from the brain? This activity is a fun and surprising way to find out! Read more

Floods

Science Fair Project Idea

Scientific Method

Floods can be very destructive, capable of leveling whole towns and decimating crops and fields. Typically in regions prone to flooding there are cycles of flooding that occur, usually in areas where a wet season comes after a period of drought. You can use precipitation data to test if incidents of flooding have been preceded by periods of drought. Look for long periods of dryness in the precipitation data to indicate a drought. You can also conduct an experiment on dry or moist soil to see… Read more
