Finger Paint Fractals

Blog Post

Kids can explore fractals and search for similar and repeating patterns with a family-friendly science activity at home. Beautiful Math Fractals refer to specific kinds of patterns that repeat, often at smaller and smaller sizes. This characteristic of patterns that repeat at different scales is referred to as self-similarity. Fractals can be found in nature as well as in digital art. While the study of fractals is something mathematicians do, kids of… Read more

Free Power from the Sun!

Science Fair Project Idea

Scientific Method

Do you like getting something for nothing? Everybody likes getting things for free. How about getting energy and power for free? The Sun sends us free energy every second and all we have to do is collect it. Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how varying the angle of the solar panel, and thus the amount… Read more

Fresh Whipped Cream That Lasts

Science Fair Project Idea

Scientific Method

Fresh whipped cream is the final touch for many delectable desserts. One issue with fresh whipped cream is that it has to be used soon after it is made, especially if it is at room temperature, or it starts to collapse into goo. This is a problem for its use in frostings or inside pastries as filler. Whipped cream can be stabilized by adding unflavored gelatin. Stabilized whipped cream can be used at room temperature and it has a much longer life. But how much gelatin is just right? Try… Read more

Globs of Gluten: Weekly Science Activity

Blog Post

In this week's spotlight: a food-themed science activity that helps families explore the role of gluten in baking—and the different levels of gluten content in different types of flour. Many favorite holiday foods contain gluten, from stuffing and rolls to pies and pastries. But their different textures may have something to do with gluten. Extracting gluten from wheat flour can be sticky business, but in this science activity, families can get hands-on with their own gluten balls and… Read more

Science Fair Project Idea

Scientific Method

If your idea of a great weekend morning is taking some practice swings at a driving range, or heading out to the links to play a round, this could be a good project for you. This project is designed to answer the question, what is the relationship between club loft angle and the distance that the ball travels when struck. Read more

Growing Great Gardens: Using Human Urine as a Fertilizer

Science Fair Project Idea

Scientific Method

Every day farmers around the world apply commercial fertilizer to their fruits and vegetables to improve plant health and yield. But applying commercial fertilizer is expensive and not economically possible for some farmers in developing countries. What if they could find a way to fertilize plants cheaply? It turns out that human urine is rich in the nutrients that plants need to grow. Could urine serve as a fertilizer substitute? Find out for yourself in this plant growth science project. Read more

Harmful or Helpful? The Effects of Hydrogen Peroxide on the Roots of Plant Cuttings & on Seed Germination

Science Fair Project Idea

Scientific Method

Hydrogen peroxide (often used as a disinfectant) has also been approved for use in pesticides. This science fair project investigates whether hydrogen peroxide has any effects on seed germination or on roots of plant cuttings. Read more

Heart Rate Recovery Times

Science Fair Project Idea

Scientific Method

Over an average lifetime, the human heart beats more than 2.5 billion times, supplying blood to the entire body. When a person exercises, the heart has to work harder than usual. Have you ever wondered how quickly your heart beats when you exercise, or how long it takes to recover back to its normal rate after you are done exercising? Is the heart rate recovery time faster for people who get regular exercise compared to people who do not? Try out this science project to find out! Read more
