Bakers (and those who help bakers!) know that at some point in every baking recipe, the instructions will tell you to preheat your oven to a certain temperature. But if you’ve ever tried to bake cookies and they come out flat, or take too long, it’s possible that your oven is to blame. You might set your oven to 350°F, but how do you know that the inside of your oven actually reaches that temperature? You could use a thermometer…. or you could use sugar! Because we know… Read more
Making Ice Cream: Doing Fun Science at Home during School Closures (Activity #19)
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... making ice cream in a bag. The Science of Treats What are you doing to treat yourself these days? A glance at Instagram and Facebook suggests many of us are doubling down on comfort food and delicious treats. I know that's true at my… Read more
Making Math with Dough: Weekly Science Activity
Blog Post
In this week's spotlight: a math activity that turns playing with dough into an exploration of geometry. If you make a cube out of dough, you can measure the sides of the 3D object and multiple the length by width by height to find out the volume of the shape. If you gently and uniformly flatten (or squish) the object, you transform your original shape into a new shape with new dimensions. Does the volume change? In this family-friendly math activity, kids can have geometry fun with… Read more
Manipulating Sound Files
Science Fair Project Idea
Scientific Method
Learn how to edit sound files so that you can manipulate the recorded sound mathematically. You can either find specialized audio editing software or do background research to teach yourself about sound file structure so that you can write your own simple program to manipulate sound files. Try arithmetic operations on the sound values (e.g., adding or subtracting a constant, multiplying or dividing by a constant). How do these operations alter the sound? Try other mathematical operations:… Read more
Mapping Troposphere Ozone Levels Over Time
Science Fair Project Idea
Scientific Method
Ozone in the stratosphere protects the earth by absorbing harmful ultraviolet radiation from the sun. However, when ozone occurs in the troposphere, i.e., the air that we breathe, it is harmful to health. In this project you can use data from EPA monitoring stations to analyze the weather/climate conditions that can lead to harmful ozone levels. Read more
Marinade Science: Weekly Science Activity
Blog Post
In this week's spotlight: a food sciences family science experiment that investigates the way different ingredients make a difference in how well a marinade sticks to food. In this science activity, students simulate the process of soaking a food in a marinade by doing a controlled study with tofu, food dye, and four different ingredients that might be found in a marinade recipe. Setting up a set of standards for what the tofu looks like when soaked in different levels of dye concentration… Read more
Mean & Green: Fruit & Vegetable Hardening
Science Fair Project Idea
Scientific Method
When you open a can of green beans, have you ever wondered why the beans are not mushy, or more like a puree? Canning requires boiling the beans for a long period of time to kill bacteria, so why don't the beans fall apart into small pieces? Some fruits and vegetables—like cherries, apples, potatoes, sweet potatoes, beets, carrots, beans, cauliflower, and tomatoes—have the ability to undergo hardening, or firming of their plant tissues. A special enzyme, called pectin methyl… Read more
Measuring Height Or Distances with a Camera
Science Fair Project Idea
Scientific Method
If you know or calculate the field of view for your camera, you can use it to measure distances and the height of almost anything. It's all a matter of basic trigonometry. Read more
Measuring Speed with a Video Camera
Science Fair Project Idea
Scientific Method
A video camera records 30 "frames" or distinct images per second. (That's for an NTSC camera in the U.S. PAL cameras in other areas of the world take 25 frames per second.) You can use this fact to time events and measure speed. One student has used a video camera to measure the speed of an arrow shot from a bow. The following project can help you set up your experiment: Distance and Speed of Rolling Objects Measured from Video Recordings. Read more
