13 Quick Science Fair Projects You Can Do In A Day

Q: Can I do a science fair project in a day?

A: Yes! There are plenty of quick science experiments and projects you can do.

While some science fair projects require a lot of time, such as observing the behavior of a hamster or growing seeds over a few days, science experiments and projects can also be quick! If you're interested in exploring quick experiments or science projects, check out the science fair project ideas below with varying levels of difficulty to choose from.

These are the fast reactions in our Quick chemistry science fair projects!

1) acid-base reactions: mixing acids with bases quickly makes carbon dioxide gas!

2) chromatography reactions: colors can be separated out!

3) heat reactions: heat speeds things up!

Film Canister Rockets and Gas Pressure
Snap a baking-soda lid onto a vinegar-filled film canister and watch gas pressure launch it skyward.
Easy
Red Cabbage Juice as a pH Indicator
Boil red cabbage to make purple juice that turns pink in acids and green in bases.
Medium
Antacid Brands and Acid Neutralization
Add acid drop by drop to four antacid brands and measure which one takes the most acid before it gives up.
Hard
Candy Coating Colors and Paper Chromatography
Drip water onto a candy sitting on filter paper and watch hidden ink colors separate into colored rings.
Easy
Hidden Leaf Colors and Chromatography
Soak torn leaves in rubbing alcohol and use coffee filter strips to separate the hidden colors that chlorophyll covers up all summer.
Medium
Candle Color and Burn Speed
Light five candles of different colors at once and time which one burns down first.
Medium
Water-Filled Balloons and Heat Transfer
Hold a water-filled balloon over a candle flame and compare it to an air-only balloon to see which one survives the heat.
Easy
Chemical Energy in a Peanut
Burn a single peanut under a can of water and measure how many degrees the temperature rises.
Medium
Sidewalk-Scale Solar System
Shrink the solar system to sidewalk size and discover how surprisingly far apart the planets really are.
Medium
Hand-Drawn Holograms on Plastic
Scratch overlapping arcs into acrylic with a compass and watch a glowing letter float inside the plastic in sunlight.
Medium
Herschel's Infrared Light Experiment
Split sunlight with a prism and place a thermometer just past the red band to detect invisible infrared heat.
Medium
Room Temperature and Candle Burn Rate
Light identical candles at three different room temperatures and measure whether heat makes them burn down faster.
Medium
Pre-Soaked Spaghetti and Cooking Time
Soak spaghetti in water for a few hours, then boil it for just one minute to test whether pre-soaking cuts cooking time.
Medium

Science Fair Project FAQ


How do I start a science fair project?

Science fair projects are a fun and unique way to discover science by asking a question and doing a science project. We'll help you find a science fair project idea and guide you through the process of doing and presenting your science fair project with Science Fair Coach's Science Fair Project Guide.


What are some hands-on ways to find inspiration for my science fair project?

Science museums are great places to explore if you're looking for inspiration for your next science fair project or just want to learn more about science. Science museums, natural history museums, space museums, and discovery museums are all great places to do that! You can discover all sorts of interesting things about science and find cool project ideas for science fairs.

There may be free admission days or free passes to a science museum near you! Check your local library for free museum passes, nearby science museums for free entrance days and your credit card for offers.

Find a science museum near you and prepare to be awed by all that you can learn there! I always learn something new and am inspired whenever I go to a science museum!


What should I do after I have a science fair project idea?

If you have a science fair project idea, Science Fair Coach can help you turn it into a full science fair project! Starting at Introduction to Science Fairs, we'll guide you through how to do a science fair project, from designing and conducting your experiment to collecting and analyzing your findings. Then, we'll help you showcase your results on a science fair board with our Guide to Science Fair Posters.


How do I make a science fair board?

Your science fair board is where you show off your science fair project for everyone to see and learn from. With our Guide to Science Fair Posters, you can make sure your science fair board stands out and impresses at the science fair!


What is the scientific method?

The 7 steps of the scientific method helps us understand how nature works. Learn how the scientific method is used in a science fair project example, and how it's evolved through history as scientists used different ways to learn about nature with our Guide to the Scientific Method!


What is the engineering design process?

The 6 steps of the engineering design process helps us design an effective solution to a problem. Learn how to use the engineering design process with the example of the egg drop challenge in our Guide to the Engineering Design Process!


Where can I find a science fair competition?

Science fair competitions are an excellent opportunity to explore science. One of the of the premier science advocacy organizations, the Society for Science, is associated with more than 400 science fair competitions in almost every US state, as well as over 70 other countries, regions, and territories. You can find out if there's a Society of Science affiliated science fair near you!

The www Virtual Library: Science Fairs website also has a collection of science fairs from all over the world, as well as national, state, regional, local, and virtual competitions!
