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

Bioprinting: 3D Print with Living Cells! No 3D Printer Required.

Science Fair Project Idea

Scientific Method

Do you get excited about 3D printing technology? Do you like to think about other applications for this technology? 3D printing techniques can also be used with living cells, a method called 3D bioprinting. In this science project, you will explore 3D bioprinting a gelatinous substance with plant seeds. This process is similar to real 3D bioprinting techniques being explored to create tissues and organs. Read more

Heart Health: How Does Heart Rate Change with Exercise?

Science Fair Project Idea

Scientific Method

Your heart starts beating before you are born and keeps right on going through your whole life. Over an average lifetime, the human heart beats more than 2.5 billion times. Keeping your heart healthy means eating right, not smoking, and getting regular exercise. Which of your favorite physical activities give your heart the best workout and help keep it fit? In this science project, you will use a smartphone equipped with a sensor app to visualize your heart rate and find out which… 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

No Pain, Lots of Game

Science Fair Project Idea

Scientific Method

You might have heard the expression, "Take two aspirin, and call me in the morning." What if instead a doctor said, "Play two video games and call me in the morning"? Would you be shocked? Or think it was time for a new doctor? In this science fair project, you'll investigate whether video games, and other forms of mental distraction, have the power to relieve pain. Read more

Testing Sunscreen Effectiveness and Water Solubility

Science Fair Project Idea

Scientific Method

What should you NOT forget when going outside on a sunny day? To put sunscreen on! Sunscreen is important because it protects your skin from sunburn. But there are so many sunscreens to choose from: different methods of application (sprays and lotions), different Sun Protection Factors (SPFs), and different ingredients. Which one is best? In this science project, you will test the effectiveness of different sunscreens and find out how water-soluble they are. Read more

What Makes a DNA Fingerprint Unique?

Science Fair Project Idea

Scientific Method

Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events! Read more

Effects of Exercise: Changes in Carbon Dioxide Output

Science Fair Project Idea

Scientific Method

You might know that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? In this project, you will get a peek into the fascinating science of exercise physiology and find out—with the help of a color changing reaction. Read more

Comparing the Sweetness of Sugar & Sugar Substitutes

Science Fair Project Idea

Scientific Method

Cake, cookies, pie, ice cream, hot chocolate, lemonade... Yum! What do all these delicious treats have in common? Sugar. In addition to providing sweetness, sugar adds bulk, flavor, and structure to foods. But is it necessary to add sugar to achieve sweetness? Can the same sweetness be achieved using sugar substitutes like artificial or natural sweeteners? In this project, you will test sugar and sugar substitutes and compare the sweetness of each in relation to sugar. In the end, your day will… Read more

How Are Antibodies Used for Blood Typing?

Science Fair Project Idea

Scientific Method

Have you ever heard about different blood types? Do you know what your blood type is? Antibodies help scientists determine different human blood types. This project is a practical introduction to the human immune system in which you will learn about what antibodies are, how they are formed, and how they can be used to identify different types of cells.
