Do you know you can change the colour of white flowers by placing them in a pot of food colouring and water? This easy colour-changing flower science experiment is great for learning about transpiration and transport in plants. Easy Transpiration Experiment How to make colour-changing flowers You’ll need White flowers Food colouring – we’ve found…
Find out how to dissect flowers and learn about their structure with this simple hands-on dissection activity and other exciting plant experiments for kids. Dissecting a flower is a great way to visually show the different parts of a flower, which can be hard to picture from a diagram in a book. What you need…
Candle carousels date back to the 1800s and originated in Germany. They are thought to have been inspired by windmills. Early versions were very simple, but over time, they became more elaborate with multiple tiers. Today, candle carousels are found around the world as decorations. The basic structure of a candle carousel is a central…

Here at Science Sparks HQ, we love a bit of magic, whether it be a memory trick, slight of hand or even some science magic. These 10 easy science tricks for kids are great fun and mostly super simple. The density one is a little tricky and potentially messy, but well worth the effort for the…
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…
The Moon doesn’t make its own light. We see it because light from the Sun reflects off the lunar surface, but why does the Moon look white? If you could actually stand on the Moon, it would look mostly grey with areas of brown and yellow, depending on the minerals present. The Moon appears white…
Rockets are a great STEM challenge in any form, as the end result is usually impressive, and success is easy to measure. This simple air rocket launcher is inexpensive and very easy to create. It’s a great STEM challenge or science activity for home or school. Once you’ve made an air rocket launcher, take a…
This simple science project shows you how to make a model of an eclipse to visually demonstrate what’s happening between the Sun, Earth and Moon during a solar or lunar eclipse. A solar eclipse model is a fantastic science project for home and school, especially just before or after an eclipse! You’ve probably noticed shadows…
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…
