Bits, Bytes, and Bases: Write a JavaScript Binary/Decimal/Hexadecimal Converter
Science Fair Project Idea
Scientific Method
This is a challenging first computer science project. You'll learn the basics of how digital devices can represent numbers using only 0's and 1's, and you'll write a JavaScript program to convert numbers between binary, decimal and hexadecimal notation. Read more
Boys and Girls All Around the Town
Science Fair Project Idea
Scientific Method
Do you ever say you like to go somewhere, and your friend says, "Yuck, that's for girls!" or "Ewww, that's for boys!" Do this experiment to find out if there are some places that girls like to go more than boys, or vice versa. Read more
Bridge Science: Weekly Science Project Idea and Home Science Activity Spotlight
Blog Post
In this week's spotlight: an civil engineering project that lets students and families experiment with bridge design. You may be familiar with famous suspension bridges like the Golden Gate Bridge in San Francisco, but how does a suspension bridge really work? How do the cables work to support the weight on the bridge? Can a suspension bridge carry a greater load than a beam bridge? With common household materials, you can put your own straw-based bridges to the test. How many pennies can… Read more
Bringing Science Magic to the Classroom
Blog Post
A magic milk rainbow may be all about what's happening at the surface level between milk and soap, but when kids create the magic, the learning excitement is palpable. For Lily Arendt, hands-on science activities are a great way to help kids uncover the magic of science. We couldn't agree more! Above: Lily Arendt and a class of students explore surface tension with the Make a Milk Rainbow science activity. For Lily Arendt, a biology student at DePaul University in Chicago and a… Read more
Bubbly Soda Science: Weekly Science Activity
Blog Post
Making your own carbonated beverage can be a lot of fun. How much fizz do you like? What flavor? How sweet? The process of carbonating water and serving up a custom beverage is easier than ever before thanks to commonly available household devices like Sodastream®. But a pressurized approach to creating a carbonated beverage is not the only way to prepare a refreshing soda-style drink. With a few simple ingredients, students can experiment with mixing up their own… Read more
Build an Adaptive Game Controller for a Raspberry Pi
Science Fair Project Idea
Engineering Design Process
People with limited mobility, especially in their hands, may not be able to use traditional video game controllers. Adaptive game controllers use a variety of peripherals, like larger buttons, foot pedals, or specialized joysticks, to let people with limited mobility play video games. This video shows how to build a very simple adaptive controller that works with Scratch games on a Raspberry Pi. Can you build an adaptive game controller for a hardware platform and game of your choice? If you… Read more
Build Your Own Helio Tracker—a Self-powered Mechanical Sunflower that Turns with the Sun
Science Fair Project Idea
Scientific Method
The amount of energy produced by most photovoltaic (solar) panels is limited, due to their immobility. However, when photovoltaic panels track the movement of the Sun, their efficiency increases significantly. This can be done with computers and sophisticated electronics, but for rural or wilderness settings, a "low-tech" sun tracker would be beneficial. A solution exists in nature: the sunflower. The challenge in this science fair project is to design and build a device that imitates the… Read more
Build Your Own Xylophone Out of Copper Pipe
Science Fair Project Idea
Scientific Method
Did you know that making a musical instrument is not just an art, but a science, too? You can discover just how scientific by building your own xylophone (or a set of chimes) from copper pipe. First you'll need to do some research about the math and physics involved in the sounds of a xylophone. For example, there are equations that describe the transverse (side-to-side) vibrations of a pipe. These vibrations create the sounds you hear. So, to get specific sounds, xylophone makers must apply… Read more
Building Paper Bridges: Family Science Spotlight
Blog Post
Build bridges from paper to explore civil engineering in this family STEM activity. Does the shape of the materials make a difference? What helps make a bridge strong? In this family science activity, explore bridge engineering with kids by making paper bridges that stretch between stacks of books. How does changing the shape of the materials (the paper) change the strength of the bridge? This is a fun and creative science activity you can do with… Read more
Building Toys: Doing Fun Science at Home during School Closures (Activity #5)
Blog Post
Follow along with a Science Buddies parent who is using family STEM activities to keep her kids learning at home during the COVID-19 school shutdown. New posts every Monday, Wednesday, and Friday. Today's adventure... playtime and science time converge when building parachutes for favorite toys. Building Toys Drives Away Boredom "I'm bored" is one of those sentences I hate as a parent. It ranks right up there with "Are we there yet?". These days… Read more
