Easy FIVE MINUTE Science Experiments
January 8, 2024 By Emma Vanstone Leave a Comment
These easy five-minute science experiments are great when you need a quick science activity or demonstration but don’t have a long time to prepare or run an investigation.
Each q uick and easy science experiment uses materials you probably already have and are quick and easy to prepare, carry out and clear up afterwards.
Ten quick and easy science experiments
Test reaction time.
All you need to test your reaction time is a ruler and a willing helper. This activity takes less than five minutes, even if you do it a few times! If you don’t have a ruler, print my reaction time template and use that!
Make an Optical Illusion
A basic optical illusion is easy to create using paper, pens and a straw or pencil. I also have a handy template you can use to make it even speedier.
Refraction reversing experiment
Use a simple glass of water to reverse writing or a drawing. This activity is simple but very impressive and can be themed in many different ways. My favourite is our Alice’s Adventures in Wonderland reversing signs .
Is your arm span the same as your height?
Find out if your arm span is the same as your height with a simple investigation. The best thing about this activity is it needs zero resources!!
Another similar idea is to work out how many of your own feet tall you are .
Straw Rockets
These simple straw rockets take just a few minutes to build and test and can be used over and over again.
Paper spinners
If you haven’t made a paper spinner , you’re missing out! Spinners are very easy to make. You only need paper, scissors and a paperclip, and they always work!
We like to experiment with big and small spinners to find out which falls the fastest.
Inertia ball drop demonstration
A simple inertia demonstration using a glass and a lemon takes just minutes to set up and always gets a big thumbs up from an audience.
Just pull the yellow card quickly to the side and watch as the lemon drops into the glass!
Unbreakable egg experiment
Find out how to make an unbreakable egg . This almost always works, but be ready for some mess, just in case.
Make a rainbow
Did you know you can make a rainbow even on a cloudy day? You will need a prism for this, but these are inexpensive to buy.
If the sun is shining, you can use a hosepipe to see a rainbow. Stand with your back to the sun and spray the hosepipe into the air. A rainbow should form in the water droplets.
Density Jar
A simple density jar is easy to create and uses just oil and water. Kids love to find different objects to float on each layer, and if you have more time, you can create a density column with more layers.
DIY Phone Speaker
Learn about sounds and how they are amplified with a simple DIY mobile phone speaker .
If you can think of any more five minute science experiments , let me know!

5 Minute Easy Science Experiments
Below, you’ll find 20 fun, 5 minute science experiments ideal for grades K-5 . They’re simple enough for younger kids but can be adapted for older kids, making them great for mixed-age groups. Plus, I’ve added tips to make science with kids even easier! These might seem like magic tricks, but plenty of fantastic science is involved.
💡 For younger kids (kindergarten to 2nd grade) , the focus should be on making the activities simple, fun, and visually engaging while introducing basic scientific concepts in easy-to-understand terms.
💡 For older kids (3rd to 5th grade) , you can add science vocabulary surrounding the explored concept, such as surface tension, reaction rates, density, and solubility. Each of the experiments below will further explain the science behind the experiment.
1. Magic Milk Experiment
Grade Level : K-5 Pour whole milk into a shallow dish and add a few drops of food coloring near the center. Dip a cotton swab in dish soap and touch it to the milk’s surface. Watch as the colors swirl and dance around! This experiment introduces the concept of surface tension and the role of fat molecules in milk.
2. Balloon and Static Electricity
Grade Level : K-3 Rub a balloon or wool on your hair, then use the static charge to move small paper pieces or bend a stream of water. It’s a simple way to introduce static electricity and how charges interact.
3. Dancing Raisins

9. Soap-Powered Boat
Grade Level : K-3 Cut a small boat shape from cardstock, place it on water, and add a drop of dish soap. Watch it zoom across the surface as soap reduces the water’s surface tension.
10. Pepper and Water Trick
Grade Level : K-5 Sprinkle pepper on water, then dip a soap-covered finger into it. The pepper scatters as the soap breaks the surface tension. This is a fun way to show how molecules behave in water.
11. Blowing Up a Balloon with Baking Soda and Vinegar
Grade Level : K-5 Using a bottle, baking soda, vinegar, and a balloon, show how the chemical reaction creates gas that fills the balloon. This is an easy and exciting way to visualize gas production during a reaction.
12. Screaming Balloon
Grade Level: 2-5 Make a balloon scream! Blow up a balloon and place a hex nut inside, then spin the balloon in a circular motion. The nut makes a “screaming” noise as it vibrates inside the balloon, introducing kids to sound waves and vibration. This experiment is a quick and fun way to explore how sound is created by movement and interaction with objects.
13. Penny Drop Water Experiment
Grade Level : 2-5 Using a penny, a dropper, and water, see how many drops of water can fit on a penny before spilling over. This simple experiment demonstrates surface tension and cohesion.

16. Toothpick Star Experiment
Grade Level : 1-5 Bend toothpicks and arrange them into a star shape. Add a few drops of water to the center, and watch the star “magically” open! For younger kids, focus on the fun shape change, and for older students, explain how the water moves through the toothpicks by surface tension , making the star expand.
17. Density Jar Column
Grade Level: 3-5 Pour layers of different liquids, such as honey, dish soap, water, oil, and rubbing alcohol, into a clear glass, being careful not to mix them. Watch as each liquid forms a distinct layer based on its density. Kids can then drop small objects, like beads, into the column to see which layers they float or sink in.
18. Egg in a Bottle
Grade Level: 3-5 This classic experiment demonstrates air pressure and how temperature changes can create a vacuum effect, drawing the egg into the bottle.
19. Homemade Slime
Grade Level: K-5 This hands-on experiment demonstrates how chemical bonds form when ingredients react to create a stretchy, non-Newtonian substance. Kids can explore how adding more or less saline solution affects the slime’s texture, providing a fun introduction to polymers and chemical reactions
20: Water Refraction Experiment
Grade Level: K-5 This simple experiment introduces kids to the concept of refraction—how light bends as it passes through water. For older students, you can discuss how light changes speed when it moves from one medium (air) to another (water), creating the illusion of a reversed image.
