In this science activity, you can put a balloon into a candle flame without it popping! How is that possible? It’s all about heat transfer. A balloon filled with air will pop when it gets too close to a flame as the heat from the candle warms the balloon’s skin and weakens it. The trick…
A solar eclipse is when the Moon passes between the Sun and Earth, blocking the sun’s light. People on Earth who are in the path of the moon’s shadow will be able to see the eclipse. The Sun is 400 times wider than the moon and 400 times farther away, which is why they appear…
This simple science experiment and demonstration is a great way to show children what happens to gases when they are heated. The air around us is an example of a gas. Particles in a gas can move freely in any direction. Gases don’t have a fixed shape but fill the space they have. When a…
This DIY stomp rocket is one of the simplest things I’ve ever made and works amazingly well! Even our heavy kitchen roll and cardboard rocket flew high up into the air. All you need to make your own stomp rocket is an empty 2-litre plastic bottle, plastic tubing and paper. It’s that simple! Once the…
Hot air balloons work thanks to convection currents. The heat source under the balloon heats the air inside. A convection current inside the balloon keeps the air warm as heated air continually rises, cools and falls to be heated again. The warm air inside the balloon is less dense than the cooler air on the…
Rockets make a great science project or space-themed STEM Challenge as they are fairly easy to make, can be personalised however you want and reused over and over again. These easy rockets kids can make are also fun craft projects and can be turned into a science investigation! My personal favourite rocket is our mini…
Ice is great for lots of science experiments and investigations. It’s cheap, easy to make and always fun to experiment with. Today, we are going to try a cool science trick where a wire cuts through an ice cube. Ice usually needs to be warmed up to melt, but you can also make ice melt…
This collapsing bottle air pressure experiment is also a fun science trick! The bottle collapses without anyone pushing or pulling it. Adult supervision is needed for this activity, as hot water is used You’ll need Hot water – ask an adult to help A plastic bottle with a lid – different size bottles are good…
This straightforward science activity is an excellent demonstration of air pressure! When the lit candle runs out of oxygen, changes in air pressure lead to the water level in the glass rising upwards. This activity requires adult supervision. You’ll need Matches A pint-sized glass or jar Egg cup or candle holder Small tealight candle Water…
Electromagnets are electrically powered magnets that can be turned on and off. You can make your own electromagnet with a simple battery-powered circuit and a screwdriver or iron nail. As electricity flows through the wire coiled around the screwdriver, it creates a magnetic field which magnetizes the metal of the screwdriver. This activity should be…
