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

Blog Post

In this week's spotlight: a mammalian biology project and family activity that encourages families to talk about and explore why puppies and other animals huddle together for warmth. Does cuddling up really increase warmth? Put it to the test in this hands-on science experiment! Huddle & Cuddle: How Puppies Keep Warm (full Science Buddies Project Idea) Snuggly Science: How Puppies Keep Warm (science activity at Scientific American) Read more

Rad Radishes: Effects of Irradiation on Seed Germination

Science Fair Project Idea

Scientific Method

DNA is the "instruction manual" for the successful growth of a living thing, from a single cell to a mature adult. When the DNA of an organism is somehow damaged, it can have an impact on the organism's development over time. In this plant science fair project, you will track how irradiation (exposure to radiation) of radish seeds affects germination (sprouting of a seedling from a seed). Read more

Recording on a Wire

Science Fair Project Idea

Scientific Method

Today magnetic recording is used in audio and video cassette recorders, and computer disk drives. Did you know that you can also use an electromagnet to record and play back from a steel wire? In fact, this is how magnetic recording got started. This project shows you how to build a simple wire recorder. Read more

Riprap: It's Not Hip Hop But Erosion Stop

Science Fair Project Idea

Scientific Method

Have you ever been to the Grand Canyon and seen what water can do over millions of years? When you turn on the faucet, do you see water come out, or mud? In this experiment you'll find out how engineers help prevent erosion, which keeps dirt out of our water. Read more

Rock On! Recording Digital Data with Magnets

Science Fair Project Idea

Scientific Method

This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data "bits." You'll also learn about how much information can be stored in a small space (recording density), and how magnetic data can be erased. Read more

Rocket Science: Weekly Science Project Idea/Home Science Activity Spotlight

Blog Post

In this week's spotlight: a pair of projects that fit right in with U.S. 4th of July celebrations and let you get hands-on with "rocket" science at any time of the year. What happens when you combine vinegar and baking soda? A chemical reaction! If you contain the reaction in a small space like a film canister, you can get a high-flying blast from the combination—your own mini rocket. But how much of each ingredient do you need? Experiment with the ratio of vinegar and baking soda… Read more

Salt Oscillator

Science Fair Project Idea

Scientific Method

Fill a jar a little more than half full with fresh water. Make a solution of salt water, and add a drop or two of food coloring to it. Pour the salt water solution into a plastic cup with a small hole in the bottom, and then place the cup in the jar with fresh water. (The only connection between the fresh and salt water should be via the hole in the bottom of the cup.) With the right combination of hole size and salt concentration, you will see an oscillating current develop in the jar. … Read more

Save a Life! Teach Hands-Only™ CPR

Science Fair Project Idea

Scientific Method

What would you do if you saw one of your friends lying on the floor, not breathing, possibly having a heart attack? Call 911? Start CPR (cardiopulmonary resuscitation)? Those would both be important things to do! But do you know CPR? Do your friends and family know CPR? Chances are, most of them don't. Even if they do know CPR, they might be hesitant to use their mouths to perform it. You can change that though. In this science project, you'll create a simple, interactive game that can teach… Read more

Science Activities: Fun Science Perfect for Home or School

Blog Post

Science Buddies has added a new "activities" section to its award-winning science education website. The new science activities complement the existing library of science fair project ideas but bridge the gap between science "assignment" or "independent project" and doing science just for fun at home or in the classroom. These new activities appear just as summer break begins for many students, making the timing perfect for families looking to keep kids engaged with science all summer… Read more
