Bird Science: Weekly Science Project Idea and Home Science Activity Spotlight
Blog Post
In this week's spotlight: a pair of zoology science projects that encourage families and students to use their observation skills to learn more about birds. What can you deduce about a bird's lifestyle or habitat by looking at its feet? More than you might think! Both the independent science project and the family science version guide students in an engaging bird feet scavenger hunt. The closer you look, the better, so pack a picnic lunch and head to a nearby park or… Read more
Bit Depth, Colors and Digital Photos
Science Fair Project Idea
Scientific Method
How many bits of information are in a digital photo? It depends on how many possible colors there are. Learn how to choose the right number of colors and bits to post your photo on the web or send it to your best friend. Read more
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
Breath of Life: Does Exercise Increase Vital Capacity?
Science Fair Project Idea
Scientific Method
How much air do you think you breathe in when you take a deep breath? Can you increase your lung capacity by exercising regularly? Do athletes have greater lung capacity than non-athletes? This project shows you how you can find out. 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
Bug Vacuums: Sucking up Biodiversity
Science Fair Project Idea
Scientific Method
Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more
Build a Color-Detecting Rover
Science Fair Project Idea
Engineering Design Process
The Mars Curiosity and Perseverance rovers use scientific instruments, nicknamed ChemCam (Figure 1) and SuperCam respectively, to help them analyze the composition of rocks and soil on Mars. You can learn more about these cameras from the resources in the Bibliography, and more about why scientists want to analyze rocks on Mars from the video on this page. Figure 1. The two main parts of the ChemCam instrument on the Mars Curiosity rover.  For a science… Read more
