Slip Sliding Away: Experimenting with Friction

Science Fair Project Idea

Scientific Method

As you headed up the mountain to enjoy your last ski trip, you may have noticed a sign reading: Hazard! Icy Roads Ahead—Put On Your Chains. Putting chains on car tires increases the resistance between the tires and the road allowing the car to "grip" the road. This resistance to sliding is called friction. In this experiment, you will be investigating how to increase and decrease the friction between two surfaces. Read more

Slippery Slopes and Sticking Surfaces: Explore the Forces of Friction

Science Fair Project Idea

Scientific Method

Whoopee! No matter what age, who doesn't like flying down the slides at parks and pools? In this experiment, you might be surprised what you can learn about the fascinating forces of friction while sliding down (or sticking to) those fun, slippery slopes. Caution: only speed demons need apply for this activity. Read more

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.

Smashing for Mash: The Science of Making Memorable Mashed Potatoes!

Science Fair Project Idea

Scientific Method

What do you look forward to when the holidays arrive? Spending time with friends and family? Having lots of free time? How about the delicious food that comes out of the kitchen? You bet! What kinds of food do you have on your table during those special times of the year? For many people, mashed potatoes and gravy are usually on the holiday menu. Whether light and fluffy or smooth and silk-like, mashed potatoes are very satisfying. What is not satisfying is when the cook makes a mistake in… Read more

Soil Color and Moisture

Science Fair Project Idea

Scientific Method

Have you ever taken a step onto what appeared to be dry ground, only to find yourself ankle-deep in mud? Yuck! When you walk through damp soil, it can be a very messy experience. How can you tell if soil is wet or dry before you step on it? In this science project, you will investigate whether the color of the soil can help you determine how dry or wet it is. Read more

Soil Compaction

Science Fair Project Idea

Scientific Method

Have you ever had to dig a hole in really hard soil? It is a lot of work! In this science project you can make an instrument to test the soil and find out how compacted it is, before you dig! Read more

Our planet recycles and reuses everything on it that is needed to support life. It is an amazing, giant recycling system called the biogeochemical cycle. You can actually model this on a small scale by using a plastic bottle and mud to build what is called a Winogradsky column. In this activity, you will build your own Winogradsky columns and investigate how including different nutrients can affect which soil microorganisms flourish and which fail. Read more

Solving a 'Windy' Problem

Science Fair Project Idea

Scientific Method

The wind is a powerful force, enough to erode whole hillsides over time. Building structures in windy environments challenge civil engineers with special safety concerns. A wall in a windy area can either shield you from the cold or fall down on you. Learn a few tricks on how to design walls in windy places. Read more

Students know that sounds can be heard, but do they know that some sounds can also be felt and seen? In this lesson, students will learn that vibration causes sound and build a fun musical instrument of their own. Read more

NGSS Performance Expectations:

1-PS4-1. Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate.

Spinning Colors: How Do Primary Colors Combine to Make New Colors?

Science Fair Project Idea

Scientific Method

Did you know that sunlight can actually be separated into the colors of the rainbow? And the light of different colors can be added together to make white light or new colors. This is an area of study where art and science overlap. In this science fair project, you will explore this area by drawing or painting "pie slices" onto a white circle and then combining them to make a new color by spinning the wheel using an electric drill.
