Have you ever noticed that the salt you’re using says it’s “iodized”? Iodine is a micronutrient, which means we need it in small quantities to be healthy. Because iodine is relatively rare in many people’s normal diets, it’s added to table salt. Then when people salt their food, like tasty turkey, stuffing and mashed potatoes, they’re also getting some iodine. In this science activity, you’ll use some kitchen-friendly chemistry to investigate… Read more

Have you ever seen a product labeled “biodegradable” or “compostable” and wondered just how well it decomposes? A lot of different products claim to be biodegradable or compostable, such as food containers, bags, packaging materials, and spoons and forks. Not only do they clearly come in different shapes and sizes, but they’re made of different materials as well. Do they decompose differently, and, if so, which decomposes the fastest? In… Read more

Satellite Shield

Lesson Plan Grade: 4th-7th

Learners explore the properties of materials by designing a barrier that will protect a satellite from colliding objects. They test out multiple combinations of materials and collect data on the results to determine which materials are the most effective at shielding the satellites from the hazards of space debris. Learning Objectives Students will: Design a barrier that can protect the satellite from high-velocity impacts with space debris. Explore design considerations based on… Read more

Do you have a favorite Thanksgiving dinner dish? Maybe it’s an aunt’s special cranberry sauce, or mashed potatoes combined with perfectly-seasoned gravy. Or perhaps you enjoy sinking your teeth into a succulent roasted turkey the most. Dinner rolls, biscuits, corn breads, muffins, pastries and pies may also be baked for this special meal; the foods in this group typically all contain a substance called gluten. In this science activity, you’ll explore why some foods, all made… Read more

During the holidays, we often find ourselves surrounded by a wide variety of taste sensations. Have you ever wondered how well we sense different tastes? People are generally able to discern five basic tastes: sweet, umami (also known as savory), salty, sour and bitter. Is it easier to detect some of these flavors at low concentrations compared to others? In this science activity, you (and possibly your friends and/or family) will find out by exploring your taste thresholds for sweetness,… Read more

Shape Changing with the CyberSquad

Science Fair Project Idea

Scientific Method

In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. Which property (or aspect) will change the most: the length of an edge, the surface area, or the volume?
