Lactose, Sucrose, and Glucose: How Many Sugars are in Your Smoothie?

Science Fair Project Idea

Scientific Method

Do you enjoy drinking smoothies packed full of berries and other tasty fruits? Or maybe you like drinking a creamy milkshake with peanut butter, chocolate, and bananas. Smoothies and milkshakes are often tasty to us because of the sugar in them. But did you know there are different kinds of sugar? Some ingredients in a smoothie can have more than one kind of sugar in them, and our bodies process each kind of sugar differently. In this science project, you will measure the concentration of… Read more

Learn How to Disinfect Contaminated Water

Science Fair Project Idea

Scientific Method

Have you ever thought about how fortunate you are to have safe and clean water coming out of your faucet? Many people in undeveloped nations don't have this luxury. But does that mean they can't have clean water at all? Is there an inexpensive way they could use to make their own clean water? In this microbiology science fair project, you will investigate whether or not sunlight can disinfect contaminated water. Read more

LED Dance Glove: Get the Party Started with Your Own Interactive Light Show

Science Fair Project Idea

Scientific Method

Have you ever seen clothing with built-in lights? This might sound like something out of a science-fiction movie, but electronic textiles (>e-textiles for short, also called wearable electronics or sewable circuits) really exist. Instead of using hard surfaces for circuits (like what goes inside your computer or cell phone), e-textiles weave electrical parts like batteries, wires, and lights directly into clothing that you can wear to make the clothing do fun, interesting things like light… Read more

Make a Medical Alert Fall Detector

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what someone would do if they fell, got hurt, and could not get up on their own? What if they were home alone and could not reach a phone to call for help? Or, what if they lost consciousness - is there any way to automatically detect that they fell and needed help? In this project, you will program your own fall detector, a device that can automatically detect when someone has fallen over, then sound an alarm or even send a message to someone else. Devices like these are… Read more

Making Mixtures: How Do Colloids Size Up?

Science Fair Project Idea

Scientific Method

Have you ever wondered why some things disappear when they are put in water but other things do not? For example, you may have seen that salt disappears, or dissolves, when it is mixed in a glass of water. But when you throw a rock in a stream it will not usually dissolve, and instead it will just sink to the bottom. And then there are some things that do not act like the salt or the rock. These are called colloids. If you have made Oobleck out of cornstarch and water, then you have seen… Read more

Measuring the Surface Tension of Water

Science Fair Project Idea

Scientific Method

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much. Read more

Measuring Your Taste Threshold

Science Fair Project Idea

Scientific Method

Have you ever been to a buffet and found yourself surrounded by a wide variety of taste sensations? People are generally able to discern five basic tastes: sweet, umami (also known as savory), salty, sour, and bitter. How sensitive is a person's tongue for these basic tastes? Is it easier to detect some flavors at low concentrations compared to others? In this human biology science project, you will find out by exploring your taste thresholds for sweetness, saltiness, and sourness. Get ready to… Read more

We see ourselves in a mirror because mirrors reflect light. Light interacts with materials in different ways; for instance, shiny surfaces like mirrors are able to change the direction of light. In this lesson plan, students will demonstrate how light bounces off a reflective surface by redirecting a light beam from a flashlight to different locations within the classroom. Students will then be challenged to use their knowledge about mirrors to find a way to guide a light beam to a specific… Read more

NGSS Performance Expectations:

1-PS4-3. Plan and conduct investigations to determine the effect of placing objects made with different materials in the path of a beam of light.

Have you ever wondered why you need to get a flu shot regularly? The vaccine protects you from getting sick with the flu, which is an infectious disease. Such diseases, like the flu or COVID-19, can easily spread through a population and cause a pandemic by making many people sick. Measures such as social distancing can reduce the risk of catching the disease, but real protection only comes from gaining immunity against the disease. This is the reason for vaccinations—to make someone… Read more
