12 Amazing Science Projects Your Kids Will Absolutely Love

12 Amazing Science Projects Your Kids Will Absolutely Love


Science doesn’t have to stay in the classroom! With a little bit of know-how everyday household items can reveal the mind-blowing science all around us. Who doesn’t love to play and learn at the same time? Whether your motivation is a rainy day stuck indoors or quality time with the kiddiwinks, we have enough STEM (Science, Technology, Engineering and Maths) experiments to keep little hands busy for hours! Team Trunkaroo have curated 12 science projects that will fill your mini makers with wonder.

Slime Time (via Trunkaroo)

Make this gooey, sticky slime that behaves very strangely under pressure! Your cornflour slime behaves like a liquid and a solid at the same time. The more pressure you apply to the slime, then the harder it gets as particles push against one another. Less pressure allows the particles to slide over one another. Try experimenting using different amounts of pressure from your little finger to your whole hand!


Lolly Stick Chain Reaction (via Science Sparks)

Half the joy of building something is getting to knock it down again! So how about building something to set off an explosion of jumping parts? Cool, huh? The lolly stick chain reaction is a fantastic example of potential and kinetic energy. As you weave the sticks together your can feel the tension as the press and pull against each other. When you set off the chain reaction all of that potential energy turns is released into kinetic energy as the sticks shoot up in different directions!

Water Bugs Experiment (via Trunkaroo)

 These craft water bugs can teach little Einsteins all about the science of floating! When we give the water bug bigger feet it creates a larger surface area. This means the weight of the bug is spread more evenly over the water’s surface, helping it to float. Oil, the main component in butter, repels water so by spreading butter on the bug’s feet it helps it to stay afloat.


DIY Bouncy Balls (via BabbleDabbleDo)

Playtime with polymers! Not only are these homemade bouncy balls a ton of fun but they provide another handy science lesson. You mix together white glue and wet cornstarch, both of which are polymers. A polymer is a substance made up of a long chain of molecules, and is usually flexible in nature like plastic. In this experiment the borax causes the molecules in each of the two polymers to interconnect and become even more elastic, making an excellent bouncy ball.


Flying Tea Bag Fun (via Trunkaroo)

Science doesn't get cooler than this!  Learn how to launch an empty tea bag with this fun and simple science experiment.  You'll never look at tea bags the same way again! This experiment uses the same principles that allow hot air balloons to fly.  Warm air rises. When you light the tea bag, the warm air that is created rises and carries the tea bag with it.  

Giant Bubbles (via RedTedArt)

 These monster bubbles will provide hours of outdoor entertainment. But how on earth do these incredible bubbles work? Bubbles are made from a soapy water film that is filled with air. When you blow a bubble, you increase the amount of air inside it so the film expands outwards making the bubble bigger and bigger.  


Crayon candles (via Trunkaroo) 

You can make a super cool crayon candle and learn all about states of matter too! High temperatures can change solids in liquids, and when cooled those liquids can change back into solids again.


Overnight Crystal Garden (via SickScience!) 

Grow pretty crystals and brush up on chemistry. Crystals are made from groups of molecules bonding together, and when the water molecules in the magic solution evaporate, the molecules that are left over stick together to make a crystal. The evaporation process is accelerated by the ammonia, which evaporates more quickly than water. The magic crystals that are left behind are a combination of the laundry bluing and the table salt.


Coin Cleaning (via DadLab)

Raid that piggy bank and get a chemistry experiment on the go! Coins look ‘dirty’ because copper and oxygen react to form copper oxide, which we also call ‘rust’ or ‘tarnish’. It turns out that vinegar is an acid, which dissolves copper oxide. What other acids could you use to clean a penny?


Invisible Ink (via BeardedScienceGuy)

Write secret messages with this easy peasy lemon squeezy invisible ink! Here’s the science part: lemon juice is mildly acidic and acid weakens paper. When the paper is held near heat the acid on the paper burns before the rest of the paper does, which makes the ink turn brown.


Homemade Hovercraft (via DadLab)

In between super fun hovercraft races take a minute to talk about friction. Friction is a force, or resistance, between two objects moving over each other that slows the movement down. The hovercraft works because the air from the balloon rushes underneath the CD so it is no longer touching the table but sitting on a cushion of air! Goodbye friction!


Paper Helicopter Drop (via RedTedArt)

 Make these simple paper helicopters and discover how they spin! Gravity pulls the helicopter down when it is dropped from a height. The air resists the movement and pushes up each rotor separately, causing the helicopter to spin.
