Written by Alloys are made by adding another element to a metal. Creating alloys allows scientists to combine the properties of different metals. If a heavy, strong metal is mixed with a light, weak metal in the correct amounts, the result is a light, strong metal. For example, pure iron is very malleable (its shape can be … Continue reading “What is an alloy?”

Helicopter seeds are a type of seed that spin as they fall from a tree. The spinning movement and the fact that they are light and can catch the wind allows them to travel further from the parent tree than if they just dropped to the floor. This is one method of seed dispersal used … Continue reading “Flying Helicopter Seeds – science investigation”

Over the many years I’ve been writing Science Sparks, Autumn has always been my favourite season to design themed activities for. I love the colourful leaves, dark nights, cooler weather, and of course, the run-up to Christmas is always exciting too! This collection of fall science experiments and activities makes me smile every time I … Continue reading “20 Autumn and Fall Science Experiments”

Almost everything to do with food and cooking involves science. Food is kept in a fridge to slow down the growth of microorganisms, some foods are preserved in vinegar others are kept in the dark. Bitterness in food and drink can be reduced by adding salt. Need to ripen a banana fast, no problem, pop … Continue reading “Science kitchen hacks that really work”

You might have already seen our exploding seed pods and flying seed helicopters for learning about different types of seed dispersal. This activity teaches children about sticky seed pods. The challenge is to make a container for a seed that sticks ( temporarily ) to clothing. One way plants disperse their seeds is by using … Continue reading “Sticky Seeds – a seed dispersal investigation”
