Have you ever wondered how strong hair is? When we talk about our hair we usually discuss color, length or texture. But what about hair strength? If you look at a strand of hair, it looks like a very thin string. In fact, it is on average only about 0.1 millimeters thick. It doesn't seem like such a thin string could withstand much force. How much weight do you think a single strand of hair can carry? In this activity you will put a hair to the test and find out. You might be surprised by your… Read more

Improving Focus for People with Neurodevelopmental Disorders

Science Fair Project Idea

Scientific Method

Have you ever wondered how you could help yourself or your classmates focus or perform better in class? Many students do! Some kids diagnosed with a neurodevelopmental disorder learn better in different ways, and easy changes while performing a task can make a huge difference to them. In this science project, you'll test if standing can significantly improve your performance and if this further improves performance for those who have neurodevelopmental disorders. Read more

Iron-Rich Foods: How to Get the Most Out of Them

Science Fair Project Idea

Scientific Method

Did you know that your body needs a certain amount of iron in order to stay healthy? Iron can be found in much of what you consume each day. Almond flour—frequently used in cookies—is just one example of an iron-rich food. However, only a small fraction of the iron in food gets absorbed by the body, partially because the body can only absorb dissolved iron. In this project, you will study whether the acidic environment in your stomach helps dissolve iron. You will use a color-based… Read more

Is Plant-Based Milk as Protein-Packed as Dairy Milk?

Science Fair Project Idea

Scientific Method

What kind of milk do you drink in your household? Do you drink 2% dairy milk, whole dairy milk, or plant-based milk like almond milk or soy milk? Have you ever considered why you drink it? As more sustainable and alternative food options become increasingly available, people are interested in the nutritional value of plant-based foods. The US government dietary guidelines state that dairy milk is a good source of protein. Are plant-based milk sources also a good source of protein? In this… Read more

Make a Communication Aid To Help People Show Their Feelings

Science Fair Project Idea

Engineering Design Process

Have you ever tried to communicate with a baby or toddler who cannot talk yet? What about another kid or an adult who cannot speak due to a medical condition? There are many ways we can communicate without speaking, like writing or using sign language. We can also use technology to help make it easier to communicate. In this project you will program your own communication aid to help someone who cannot speak show their emotions or simple messages. 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

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

Measuring Your Threshold of Hearing for Sounds of Different Pitches

Science Fair Project Idea

Scientific Method

If you're like most people, you like listening to music. Have you ever wondered how your ears and your brain turn the sound waves out there in the world into the experience of music in your head? If you're interested in doing a project about how we hear, this is a good one for you. With this project, you'll do background research and make measurements to understand how the sensitivity of your own hearing varies with the pitch of the sound. Read more

Minding your Mummies: The Science of Mummification

Science Fair Project Idea

Scientific Method

Have you ever seen or heard of the movies The Mummy or The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog. Read more

Model How Environment and Genetics Change the Chances of Getting Cancer

Science Fair Project Idea

Scientific Method

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more
