Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! People often do this using dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. Eggs can be dyed in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this activity, you will dye eggs with silk ties and… Read more

Explore the Effects of pH on Lead Testing.

Science Fair Project Idea

Scientific Method

Lead is a very hazardous element. Even very small amounts can cause health problems, especially in babies and young children. One way to determine if a household item, such as a toy or a piece of jewelry, contains lead is to soak the item in a solution, and then test the solution for lead that might have leached out of the item. The goal of this chemistry science fair project is to determine how varying the pH of the test solution affects its ability to dissolve lead, which is a critical step… Read more

If you’ve ever accidentally let go of a Helium balloon while outside, then you know that some gases are less dense than others. In the case of your Helium balloon, it most likely floated away before you could catch it, because Helium is much lighter (or less dense) than the air in our environment. We don’t often think about gases having density, but they do! In this activity you’re going to explore the different densities of some common household gases, including the air that… Read more

Did you know that flour can explode? Luckily, this does not happen spontaneously on your kitchen counter, but only if the conditions are right. The trick is that you need a very fine powder of flour to make an explosion happen. In fact, any solid flammable material that is dispersed in the air as a dust cloud will explode once it is ignited. Why is that? It has to do with the particle size of the solid material, which determines how rapidly a chemical reaction takes place. In this activity, you… Read more

It’s happened to most of us; you wear a brand new shirt to school or work, and in the middle of lunch, get a giant ketchup stain right in the middle of the shirt. Or maybe peanut butter. Or maybe spaghetti sauce. Whatever the stain is, it’s always ugly, and can be tricky to remove. Did you know that there are many different kinds of stains, and each requires different types of cleaning to get the stain out? If you try to clean a mustard stain using shower cleaner – you… Read more

With the peak of camping season behind us, any leftover marshmallows can be offered up to science exploration! Did you realize that this sticky, tasty treat is nothing more than air trapped in a stretchy substance? Have you ever tried to expand a marshmallow without getting your hands all sticky? How did you do it? And how big did it get? Blowing up marshmallows is what this activity is about. You might not “see” a gas like air, but could it help puff up a marshmallow? Be ready to… 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
