Racial and Gender Bias in AI-Generated Images

Science Fair Project Idea

Scientific Method

If someone asks you to draw a picture of a doctor, lawyer, or engineer, what first pops into your mind? The race and gender of the person you imagine might be shaped by your personal life experiences, such as whether you have family members in those professions, or what representations of them you have seen on TV or online. What do you think will happen if you ask an artificial intelligence (AI) program to generate the picture instead? Will pictures generated by AI reflect the true real-world… Read more

Radiant Radish Seeds

Science Fair Project Idea

Scientific Method

We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know that the sun gives off harmful radiation and heat. How much radiation and heat can a seed handle? Find out using some radish seeds, an oven, and your microwave! Read more

Recycling Greywater: Can Plants Tolerate It?

Science Fair Project Idea

Scientific Method

One way to conserve water is to find safe ways to use it more than once. Here is a project to test whether greywater (water that has been used for washing or bathing) can be used for watering ornamental plants. Read more

Ring of Fire 1: What Volcanoes Tell Us About Plate Tectonics

Science Fair Project Idea

Scientific Method

The Ring of Fire is a region of volcanic and earthquake activity that surrounds the Pacific Ocean. In this project you can explore the connection between plate tectonics and volcanic activity by mapping historical data. Read more

Rise to the Occasion: Investigating Requirements for Yeast Fermentation

Science Fair Project Idea

Scientific Method

Did you ever wonder how yeast makes bread dough rise? This project will show you what yeast does to make this happen. You'll also investigate the conditions yeast needs to grow. Read more

Rocking the Boat

Science Fair Project Idea

Scientific Method

When a ship rocks back and forth, it can make people seasick. Even worse, it can make it dangerous for jets to land on aircraft carriers. For these reasons and many others, it's important for engineers to design bilge keels (or fins) to keep boats from rolling back and forth. Become an engineer for a day and discover the best way to keep from rocking the boat in this engineering science fair project! Read more

Imagine rolling two identical cans down a slope, but one can is empty and one is full. Which one will reach the bottom first? You might have learned that when dropped straight down, all objects fall at the same rate regardless of how heavy they are (neglecting air resistance). Is the same true for objects rolling down a hill? Try this experiment to find out! Read more

Runoff and Fertilizer Use

Science Fair Project Idea

Scientific Method

Many people routinely use fertilizer for crops, gardens, and lawns. What people don't know is that each time they apply fertilizer, the fertilizer seeps through the soil into the water table. This can eventually lead to the contamination of a local water source, like a stream, pond, lake, bay, or ocean. This is an especially big problem for agricultural practices that frequently use large amounts of fertilizer on fields that are connected by irrigation channels. The run-off of fertilizer… Read more

Have you ever noticed that the salt you’re using says it’s “iodized”? Iodine is a micronutrient, which means we need it in small quantities to be healthy. Because iodine is relatively rare in many people’s normal diets, it’s added to table salt. Then when people salt their food, like tasty turkey, stuffing and mashed potatoes, they’re also getting some iodine. In this science activity, you’ll use some kitchen-friendly chemistry to investigate… Read more
