Building Structures: It's a Slippery Slope

Science Fair Project Idea

Scientific Method

Have you ever looked up at a skyscraper and thought "That is so cool!"? Building a skyscraper, or any structure, is more than just building the walls, windows, and floors. All structures require a foundation to keep them from falling down. This is especially important when a structure is built on a hill or on a slope. In this science project, you will build a tower of Lego® Duplos® on slopes with different angles. You will investigate how deep you have to dig the foundation for each… Read more

Buoyancy of Floating Cylinders

Science Fair Project Idea

Scientific Method

This science project presents an interesting puzzle. A disk of wood will float face-up; that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats on its side with the circular cross-section perpendicular to the surface of the water. If you think about it, disks and logs are both cylinders. Is there some intermediate length of cylinder that floats with the circular cross-section at a tilted angle? Try this experiment to find out! Read more

Calculating the Circumference of the Earth

Science Fair Project Idea

Scientific Method

How big a ruler would you need to measure the circumference of the Earth? Did you know that you can do it with a yardstick? (And you won't have to travel all the way around the world!) Read more

Calling It Quits: What Is the Most Effective Way to Quit Smoking?

Science Fair Project Idea

Scientific Method

Maybe you know someone who smokes, and you want to help them to quit. They've probably already told you how hard it is to stop once a person has started smoking. This project tries to answer the question: What is the most effective way to stop smoking? Read more

Can a Toilet Paper Tube Support Your Weight?

Science Fair Project Idea

Scientific Method

Here's a fun project idea to learn about compression forces. For this experiment you'll need some empty toilet paper tubes, masking tape, sand (or table salt), pebbles (or marbles), a funnel, a cardboard box, and a sturdy chair to help you balance while testing the column. Seal one end of the tube with masking tape. Use the funnel to fill the tube with sand (or salt). Seal the other end with tape. Place the tube on end inside the paper box. Place the chair with its back to the box and hold… Read more

Can Adults Pass a Middle School Science Test?

Science Fair Project Idea

Scientific Method

How well do adults understand basic science concepts? This project is a good opportunity for you to test your own scientific understanding as you create a short test to assess knowledge of basic science concepts. Your test will have to brief (probably 10-15 questions, maximum) or you'll have a hard time getting a sufficient number of complete responses. With so few questions, you'll have to think carefully about exactly what comprises "basic science knowledge," and exactly how to word your… Read more

Can AI Predict Who Survived the Titanic's Sinking?

Science Fair Project Idea

Scientific Method

Given the right data, AI can be good at making predictions. In this project, you will create a KNN machine learning model that tries to predict whether a passenger on the Titanic survived based on multiple factors such as age, sex, and fare price. This project requires little to no coding skill; instead, you will need an open mind and curiosity to learn. Ready to give it a try? Read more

Can Aloe Juice Save Your Berries from Mold?

Science Fair Project Idea

Scientific Method

Fuzzy things are often cute, but not when that fuzziness is mold on your strawberry—yuck! Companies look for natural, plant-based ways to protect the berries from mold when they are in the store, waiting for you to purchase them. Would washing them in aloe vera juice protect strawberries from mold? Do this project and find out! Read more

Can Baking Soda Substitute for Baking Powder in a Recipe?

Science Fair Project Idea

Scientific Method

There's nothing quite like the smell of fresh-baked muffins for breakfast on a Saturday morning! If you're into baking, you might want to try this project, which will give you insight into some of the chemistry that's going on in your muffin batter. You'll get some practical knowledge about substituting ingredients. Who knows, it may even get you started on the path to some new culinary inventions! Read more

Can Beeswax Wraps Replace Plastic Wraps?

Science Fair Project Idea

Scientific Method

Do you ever use plastic wrap to cover a container? Did you know that it is made of plastic, which significantly contributes to the amount of waste in our landfills? There are many alternatives to plastic, and one popular product is beeswax wraps. Are beeswax wraps a suitable replacement for plastic wrap? Find out in this experiment! Read more
