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

Which Skin Moisturizer Works Best?

Science Fair Project Idea

Scientific Method

Does your skin get dry? Or do you know someone with dry skin? Dry skin can be a real medical problem for some people. 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

Exploring the Impact of Social Media on Mental Health with Machine Learning

Science Fair Project Idea

Scientific Method

Do you ever wonder if you spend too much time online? How can the amount of time spent on social media influence someone's mental health? What other factors play a role? In this science project, you will investigate which variables correlate with better mental health scores using a machine learning algorithm called the Random Forest algorithm. Read more

How Eco-Friendly is Your Sunscreen?

Science Fair Project Idea

Scientific Method

Imagine a wonderful summer day at the beach. You play in the sand, swim in the ocean—and, of course, put a lot of sunscreen on. The sunscreen protects your skin from harmful ultraviolet (UV) radiation. Special ingredients absorb or reflect the UV rays so they do not harm your skin. Different types of sunscreen have different types of ingredients, and some of them can be harmful to the environment—especially if they get into the ocean. In this science project you will put your… Read more

The Tree of Life — I (basic)

Science Fair Project Idea

Scientific Method

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use a Web-based… Read more

How Sweet It Is! Measuring Glucose in Your Food

Science Fair Project Idea

Scientific Method

You know that sugar makes food sweet, but did you know that there are different kinds of sugar? Sucrose is the granulated sugar that you usually use for baking. Another kind of sugar, which is found in honey and in many fruits, is glucose. In this science project, you will measure the concentration of glucose in a variety of foods. You will use special test strips that change color in response to glucose to measure the glucose concentration in different foods. Read more

Predicting Thyroid Cancer Recurrence with Machine Learning

Science Fair Project Idea

Engineering Design Process

For cancer patients, remission–a period when the signs and symptoms of cancer are reduced or disappear–brings immense relief, but there is often a chance of recurrence, or the cancer coming back. Have you ever wondered how doctors can predict if cancer might come back in some patients? Thyroid cancer, a type of cancer affecting the thyroid gland, has a recurrence rate of about 5-30%. Depending on many factors, some patients may have a higher chance of thyroid cancer recurrence than… Read more

Caffeine and Heart Rate: A Pharmacological Study Using Daphnia magna

Science Fair Project Idea

Scientific Method

In this project, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine on heart rate. Don't worry about having to learn how to take a crustacean's pulse: you can actually see the heart beating under a microscope. Many variations of this experiment are possible. Read more

Create and Test Your Own Hydrogel Face Mask Recipe!

Science Fair Project Idea

Engineering Design Process

Have you ever tried a beauty face mask? Cosmetic face masks are skin care products that promise rapid hydration of your skin to make it look younger and more radiant. Hydrogel face masks are made of jelly-like materials that are infused with special ingredients to nurture your skin. The ingredients for cosmetic products like face masks are carefully selected by cosmetics chemists. Each product is designed to have the properties that are necessary for its intended purpose. In this science… Read more

Can You Walk the Talk? Exploring Distractions and the Timed Up and Go Test

Science Fair Project Idea

Scientific Method

Test your multitasking skills with the Timed Up and Go (TUG) Test! In this challenge, you'll evaluate a person’s functional mobility when they're focused versus when they're distracted. Can your brain handle walking and talking at the same time? Let’s find out! Read more
