Satellite Collision Detection: A Hands-On Coding Experience

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what would happen if two satellites crashed into each other in space? While space may seem empty, Earth’s orbit is actually crowded with satellites and debris. In this project, you’ll step into the role of a space engineer, using real satellite data to model orbits, track their movement, and predict potential collisions. You’ll explore how gravity and speed affect a satellite’s movement and learn how scientists use simple math and code to prevent… Read more

Have you ever wondered how butter is made? Butter is used in many tasty applications – hot pancakes with butter running down the sides, freshly baked biscuits and pastries with butter, and hot flaky potatoes with melted butter, to name just a few. Yum! While making butter can be hard work, it can also be easily made at home. In this activity you’ll not only get to find out how butter’s made, but also how temperature affects the butter-making process. … Read more

See Air Currents with Shadowgraphs and Schlieren Images

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what the air currents look like around a candle? What about cold air flowing around an ice cube, or warm air rising from your hand? What about when you sneeze? We are surrounded by air currents all the time, but these subtle movements are completely invisible to the human eye. In this science project, you will take advantage of small changes in air density to make air currents visible in regular photographs and videos, using techniques called shadowgraphy and schlieren… Read more

Seebeck Effect: Turn Heat into Electricity, Then Measure It with a Thermocouple Thermometer

Science Fair Project Idea

Scientific Method

Everyone knows electricity can create heat, especially because our electrical appliances tend to warm up when turned on. But wouldn't it be cool to do the reverse — generate electricity from heat? In this science project, you will study why it happens, measure the effect, and then use the phenomenon to build your own device, a thermocouple thermometer, that will enable you to convert heat into electrical energy.

Separating Butter with a Salad Spinner Centrifuge

Science Fair Project Idea

Scientific Method

Imagine that you could make an important piece of laboratory equipment in your kitchen. With this science project idea, you can! You will create your own centrifuge out of a salad spinner and some putty. In science labs, centrifuges are used to separate different liquids and/or solids from each other. You can load your homemade centrifuge with samples and see how they separate. What do you think happens to melted butter in a centrifuge? Read more

Do you like cooking? If you have helped in the kitchen at home, you have probably heated up lots of liquids, like water, milk, and soup. Did you notice that once the solution boils, a lot of steam develops; and have you ever wondered what the steam is made of? What happens to all the substances, such as sugar or salt, that are dissolved in the solution you are boiling? Do they boil off, too, or do they stay behind in the solution? In this activity, you will build a distillation device that… Read more

Light is fascinating! It can look like a wave or a particle; it can be red, blue or any color of the rainbow; you can even mix all the colors together to get white! It travels in straight lines and still appears to bend around objects. It can travel through air, but it does not need the air. Unlike sound, light can travel from distant stars through a vacuum and reach us years later, or it can be sent through fiber optic cables and go around the world in less than a second! Does that sound… Read more

Shaking for Butter

Science Fair Project Idea

Scientific Method

Hot pancakes with butter running down the sides, freshly baked biscuits and pastries with butter, hot flaky potatoes with melted butter. Yum! It seems like everything tastes better when you add butter. But what is butter and how is it made? In this food science fair project, you will find out, and you will test different conditions for making butter and determine the best method. Read more

Shed Light on Electric Generators: Do More Coils Generate More Electricity?

Science Fair Project Idea

Scientific Method

The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights. Read more

Simple Harmonic Motion in a Spring-Mass System

Science Fair Project Idea

Scientific Method

Many things in nature are periodic: the seasons of the year, the phases of the moon, the vibration of a violin string, and the beating of the human heart. In each of these cases, the events occur in repeated cycles, or periods. In this project, you will investigate the periodic motion of a spring, using a mini Slinky®. You can also measure the motion of your spring using a smartphone equipped with a sensor app. Basic physics will then allow you to determine the Hooke's Law spring constant.… Read more
