Kimchi Chemistry

Science Fair Project Idea

Scientific Method

You're probably familiar with sauerkraut, a German dish of cabbage that is fermented in a brine made of its own juice and salt. Have you heard of another cabbage dish, called kimchi? Kimchi is a traditional fermented cabbage dish from Korea. Koreans eat kimchi year round, enjoying its spicy taste and the fact that it contains loads of vitamins B and C. In this cooking and food science fair project, you will make kimchi from scratch and investigate changes in pH and glucose as the kimchi… Read more

Boys and Girls All Around the Town

Science Fair Project Idea

Scientific Method

Do you ever say you like to go somewhere, and your friend says, "Yuck, that's for girls!" or "Ewww, that's for boys!" Do this experiment to find out if there are some places that girls like to go more than boys, or vice versa. Read more

Motion After-Effects in Vision

Science Fair Project Idea

Scientific Method

If you stare at a waterfall, or look at passing scenery from the window of a moving train, you will have a strange sensation when you turn your gaze to something stationary. You can investigate these types of motion after-effects with simple equipment described by the Exploratorium. How long does it take to induce the effect? How long does the effect last? Can the after-effect be canceled by viewing motion in the opposite direction? (Staff, date unknown) Read more

How Sugar Content Changes in Ripening Fruit

Science Fair Project Idea

Scientific Method

You have most likely witnessed the change that occurs as a banana ripens It changes from green and relatively hard to yellow and soft. The flavor also changes, from bitter to sweet. What happens during ripening? One big change is the increase in sugar content. In this food science fair project, you will measure how the sugar content of a banana changes as it ripens. 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

That's a Real Smile! ...or is it?

Science Fair Project Idea

Scientific Method

If someone is smiling, it means they're happy, right? Well, not always. Sometimes people smile to be polite, or because they want to "appear" happy or friendly for social reasons. How easy is it to spot which smiles are genuine and which are fake? Try this science fair project to find out! Read more

What's the Fastest Way to Sort a List?

Science Fair Project Idea

Scientific Method

Imagine that you have a list of names of all the people in your class. Someone asks you to put them in alphabetical order. How would you go about doing it? Would you first go through the entire list and look for all the "A" names? Then go through it again and look for all the "B" names, and so on? Do you think going through the list over and over again for each letter would be inefficient? What if you had hundreds, thousands, or even millions of names? How would you ever alphabetize them… Read more

Rocket Science: How High Can You Send a Payload?

Science Fair Project Idea

Scientific Method

Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! Read more

Yeast Busters: Stopping Fungus in its Tracks with Antifungal Medicines

Science Fair Project Idea

Scientific Method

Have you ever wondered how antibiotics and other medicines are able to stop dangerous infections? How do such medications kill microorganisms without in general harming the person the microorganisms are infecting? Because many different types of microorganisms can infect us, we have had to develop an amazing number of ways to deal with these harmful microbes. Fungal infections can be particularly dangerous, but we have developed many different antifungal medications that can usually deal with… Read more

Testing Behavioral Incentives

Science Fair Project Idea

Scientific Method

What motivates you to clean your room/mow the lawn/wash the dishes (substitute your own responsibility at home)? What motivates you to do something you really like to do? Or think about this: you'd like to get your younger brother or sister to do you a favor. What strategy works best? Here is a project designed to test which incentive strategy works best for encouraging small children to complete a task. Read more
