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

SeaPerch: An Underwater Robot

Science Fair Project Idea

Engineering Design Process

Underwater robots, or remotely operated vehicles (ROVs), help us explore areas of the ocean that can be dangerous for humans. They can provide valuable scientific information about deep-sea life and ocean climate. However, you do not need access to the ocean to build and test your own ROV. If you have ever wanted to build your own ROV but were not sure where to start, the SeaPerch platform is a great option. You can purchase a complete kit with all the required parts and follow the detailed… Read more

Seasonal Disease Outbreaks

Science Fair Project Idea

Scientific Method

"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others. Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to… Read more

Have you ever lived someplace where you get to experience the full glory of all four seasons? If so, you know well the heady blossoms and dramatic skies of spring; the long, sun-drenched days of summer; the trees shaking in crimson and gold in fall; and the sparkling, brittle snows of winter. But do you know why we have these seasons, over and over again, in a cycle as predictable as the rising and setting of the sun? It actually has to do with the Earth’s tilt and the Moon. In this… Read more

Seasons Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: an astronomy project that lets students and families use a simple homemade setup to better understand the way the tilt of the Earth's axis causes seasons. When a surface is titled, how does the light reaching it change? With a flashlight, a cardboard box, and some ordinary paper, you can get hands-on and experiment! The Reasons for the Seasons (full Science Buddies Project Idea) Seasonal Science: The Reasons for the Seasons (science activity at… Read more

Seeing Beyond the Visible: Photography with Near Infrared Illumination

Science Fair Project Idea

Scientific Method

Have you ever wondered what it would be like to have an extra sense? What if you could hear above the normal range (ultrasound) like dogs or bats? What if you could see ultraviolet light, like bees or juvenile trout? What if you could see infrared light, like a rattlesnake or boa constrictor? This project shows you how you can use a phone or camera, tripod, and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world. Read more

Seeing Tonic Water Glow: Weekly Science Activity

Blog Post

In this week's spotlight: a chemistry-focused family science activity that puts light energy, ultraviolet light, and visible light on display. With ordinary tonic water and a black light, families can learn more about ultraviolet light. What happens to the glow when you add a bit of bleach to the tonic water? Put it to the test to find out! Explore Glow-in-the-Dark Water! (Science Buddies activity) Shining Science: Explore Glow-in-the-Dark Water! (science activity at Scientific… Read more

You probably know that some liquids, such as oil and water, do not mix together. If you pour them into the same container, they will form two separate liquid layers on top of each other. Other liquids, for example rubbing alcohol and water, can be mixed with each other. But did you know that once both of these liquids have mixed, you can separate them again into two different layers? How can you do that? The answer might surprise you: with salt! In this activity, you will find out how this… Read more

Separating Glitter with a Homemade Centrifuge

Science Fair Project Idea

Scientific Method

It is fun to shake up a snow globe and watch the "snow" slowly fall. You can imagine that if the snow fell down very quickly it would be disappointing. But there are times when scientists in a laboratory want this to happen. Scientists use samples that have liquid mixed with small, solid pieces (like the inside of a snow globe), and they need all of the solid pieces in a clump, separated from the liquid. Instead of waiting for the pieces to slowly fall out of the liquid, scientists speed up… Read more

Separating Mixtures: Can You Design a Device to Do It?

Science Fair Project Idea

Scientific Method

Have you ever looked in the kitchen cupboard and found a container of tiny white grains, but you were not sure if they were sugar or salt? They look very similar. How could you tell them apart? Well, you know that sugar and salt taste very different. Taste is actually called a property, and properties are used to describe and identify different materials. Properties can also be used to physically separate things. In this science project, you will use different properties to create a way to… Read more
