How Acidic Waters Make Rocks Disappear

Science Fair Project Idea

Scientific Method

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Hydroponics: Gardening Without Soil

Science Fair Project Idea

Scientific Method

What do plants need to grow? Most of us would answer that they need light, air, water, and soil. But by using a process called hydroponics, you can grow plants without soil! How does it work? Try this project and see for yourself! Read more

Can Plants Stop Soil Erosion?

Science Fair Project Idea

Scientific Method

Soil erosion can cost the world billions of dollars every year by washing pollutants into our streams and rivers and by causing the loss of farmland. What can you do about this problem? Help save the world (and some money!) with nothing more than a few plants! Read more

Landslides: What Causes Rocks to Slide Down a Slope?

Science Fair Project Idea

Scientific Method

Landslides are powerful geological events that happen suddenly, causing fear in people who live in areas with unstable hills, slopes, and cliff sides. Landslides damage the surrounding habitat and can destroy homes in their path. But what causes landslides? Can slides happen on any slope, or do slopes have to have certain characteristics, such as a steep angle and a specific material mass? In this geology science project, you will learn about the different types of landslides and the… Read more

Build an RC Boat

Science Fair Project Idea

Engineering Design Process

Do you like playing with radio-controlled (RC) toys like cars, planes, and boats? What if you could build and customize your own? In this engineering project, you will learn how to build your own RC boat using an Arduino and a plastic food storage container. Read more

Can Every Part of a Plant Regrow?

Science Fair Project Idea

Scientific Method

Have you ever picked a flower and tried to make it stay alive in a cup of water? How long does that last? Do some flowers last longer than others? Why do you think that is? In this experiment, you will compare different plants to see which ones can regrow or regenerate after damage and learn why some plants are better at it than others. Read more

How Fast Do Seismic Waves Travel?

Science Fair Project Idea

Scientific Method

Have you ever wondered how fast a seismic wave from an earthquake travels? In this geology science project you can figure this out using historical seismograph data that you can collect from the comfort of your own computer. You will use a web interface to a network of seismometers run by the Northern California Earthquake Data Center, at the University of California, Berkeley. From the seismograms you make, you will be able to measure the time it took for the seismic waves to travel from the… Read more

Mixing Mystery: Why Does Tumbling Sometimes Separate Mixtures?

Science Fair Project Idea

Scientific Method

What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

The Science Behind Tsunamis: Study the Effect of Water Depth on Wave Velocity

Science Fair Project Idea

Scientific Method

A tsunami is a series of waves made in a body of water, like the ocean, that can cause serious destruction when they hit the coastline. In deep water, a wave can be just a few feet high and travel very fast. As it nears the coastline, and moves into shallower water, tsunamis usually slow down, but the wave height can grow to 100 feet! In this ocean science project, you will model a tsunami and investigate how wave velocity (speed) depends on water depth. Does it match the mathematical equation… Read more

Predict Air Quality with Machine Learning

Science Fair Project Idea

Scientific Method

Air pollution is a growing issue, especially in cities, due to the rise of industrial activities, increased fossil fuel consumption from things like car use, and natural events like wildfires. This pollution is measured by the Air Quality Index (AQI), which shows how clean or polluted the air is. But what if we could predict changes in AQI to help communities plan ahead to protect people who are at risk from air pollution? That’s where machine learning comes in. In this project, you will… Read more
