What Sugar And Tea Does a Kombucha Biofilm Prefer?
Science Fair Project Idea
Scientific Method
You may have seen kombucha at the grocery store marketed as a healthy food choice. Did you know this drink is made with a special biofilm that ferments sugar into the tangy, fizzy drink? How does it do that? In this experiment, you'll learn how to make your own kombucha from a biofilm and what tea or sugar substrates you can change! Read more
Which Fruits Can Ruin Your Gelatin Dessert?
Science Fair Project Idea
Scientific Method
Why are some fruits, like pineapple, not recommended for adding to gelatin? It is because the gelatin may not solidify well if it has these fruits in it. In this science project you will determine whether certain enzymes in some fruits are preventing gelatin from solidifying, and whether there is a way to still include these fruits without ruining your gelatin dessert. It is an experiment with edible results! Read more
Which Skin Moisturizer Works Best?
Science Fair Project Idea
Scientific Method

You may have seen many kinds of lotions, creams, and ointments advertised as restorative for dry skin, especially dry hands. But how well do they work? And which ingredients are most important in making them work? In this science project, you will create a model of human skin using JELL-O® and test how well skin moisturizing products with different ingredients keep the… Read more
Who Has the Biggest Genome?
Science Fair Project Idea
Scientific Method
Humans are complex creatures, but do we have the biggest genome? All living things, from humans to worms to bacteria have genomes. In this experiment you will compare the genome sizes of different organisms to find out who has the smallest and the largest genomes. Where will we fit in? Read more
Why Aren't All Medicines Pills?
Science Fair Project Idea
Scientific Method
No one likes shots, so why don't we swallow all our medications? In this science project, you will use a model to explore one challenge behind making medications we can quickly swallow, using insulin (a medication taken by some diabetes patients) as an example. Will your medication be functional after spending time in an environment similar to the stomach? Read more
Yogurt Cultures
Science Fair Project Idea
Scientific Method
Have you ever wondered how yogurt is made and what makes some yogurts different from other yogurts? You may have noticed that most yogurt containers advertise that the yogurt contains "live cultures." This means that there are living bacteria in the yogurt! These amazing bacteria can turn plain old milk into a yummy yogurt treat. In this science project, you will investigate whether the bacteria affect what the yogurt feels, tastes, and smells like by making your own yogurt at home! Read more
