Home Sweet Bug Microenvironments: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a zoology family science experiment and science fair project that encourages families and students to observe pillbugs or sowbugs up close by creating cozy but different microenvironments and seeing which the bugs prefer. Although they are frequently found in the soil, pillbugs and sowbugs are not insects; instead, these bugs are crustaceans and breathe with gills.Will this have an affect on which microenvironment they choose? Put it to the test in this easy… Read more

Homemade Compass: Weekly Science Activity

Blog Post

In this week's spotlight: a physics-focused family science activity that can help everyone in the family get a better sense of where you are—or in what direction you are heading. In this activity, students make a small, working compass using part of a cork, a needle, and a magnet. Once the compass is created, students can put it to the test. Does the direction the homemade compass points match up to what another navigational device or app says? Families can experiment with other… Read more

Honesty: How Prevalent Is It?

Science Fair Project Idea

Scientific Method

How trusting are you? Do you think people are basically honest, or do you think people are usually honest only when they think someone is watching? This project explores how well the honor system works for a bake sale-type charity donation. Find out if your hunch is correct. Read more

Hot Pot: Choosing the Right Pot in Which to Cook Your Meals

Science Fair Project Idea

Scientific Method

What is cooking? Cooking is applying heat to food in order to help make it taste good. But the decision to cook your food doesn't end there. Do you want to cook it at a low temperature for a long time or do you want to apply high heat and cook or sear it right away? You might think that a pot is just something in which to cook your food, but it is also a cooking tool. Pots and pans are made from different kinds of materials, such as aluminum, stainless steel, iron, and ceramics. Each of these… Read more

Household Water Usage

Science Fair Project Idea

Scientific Method

How much water do you use? Conserving water can do more than save your parents' money, it can also save freshwater ecosystems, wetlands, and watersheds. Some companies are trying to help fix the problem by making low flow faucets and showerheads. How well do they work? How much water can you save? Go to the hardware store to buy a few of the water saving products. Compare the amount of water that you run over a period of time to determine how much water you can save. Which water saving… Read more

How a Comet's Size Affects How Fast It Melts

Science Fair Project Idea

Scientific Method

Comets—big lumps of rock, ice, and frozen gases that orbit the Sun—are among the most amazing heavenly objects seen in the night sky. The glowing tail behind the comet's nucleus inspires wonder. But did you know that a comet's tail is evidence that it's melting? As a comet passes by the Sun on its orbital path, it starts to melt. But do bigger comets melt faster than smaller comets? In this astronomy science project, you will investigate how the size of the comet affects the… Read more

Have you ever had to take antibiotics? Your doctor probably told you to finish taking all the pills even if you felt better after one or two days. But why is that? Why shouldn't you stop taking antibiotics as soon as you feel better? You might be surprised to hear that if you do, you might contribute to the creation of antibiotic resistant "superbugs!" Find out how these superbugs can develop in this activity by rolling dice to model how different bacteria respond to an antibiotic treatment. Read more
