Science Fair Project Idea
thumbnail There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more

Science Fair Project Idea
thumbnail Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars, glucose and sucrose, in different foods and investigate how sucrose is converted into glucose with the help of an… Read more

Science Fair Project Idea
thumbnail Do you like playing with squishy play dough or modeling clay? Wouldn't it be cool if you could add lights, sound, or even motion to your play dough creations? In this science project, you will make play dough that conducts electricity, which will allow you to connect lights, motors, and buzzers! This science project is the first in a three-part series on "squishy circuits," which can all be done with the same materials. We recommend doing the science projects in order. Read more

Material Availability This science project requires a Squishy Circuits Kit and ingredients to make conductive and insulating play dough. See the Materials and Equipment list for details
Cost Low ($20 - $50)
Safety Ask for an adult's help when using the stove to make the conductive play dough. Never connect the battery pack's terminals directly to each other; this is called a short circuit and can make the batteries and wires get very hot. Do not connect the LEDs directly to the battery pack without using play dough; this will burn out the LEDs.

thumbnail What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will… Read more
