Today’s science investigation is a fun one! We’re going to waterproof a boot – not a real one, as hopefully your boots are already quite waterproof, but a paper one! The idea is to print off the sheet, colour it in, cover it with different materials and then spray it with water to find out…
The biggest animal that lives in the sea is the blue whale. Blue whales can grow to 30 metres long, weigh up to 200 tonnes and have a heart the size of a small car! The blue whale is also the biggest animal on the planet and the largest animal that has ever lived! Are…
The idea of a map stick or journey stick is to creative a visual representation of a journey or area. Aboriginal people in Australia used journey sticks to help recount their journey to others. Items on the stick represent features of the journey. Journey sticks are sometimes called storytelling sticks as they tell the story…
You might think butterflies’ brightly coloured wings make them stand out to other animals, but the colours are often a defence mechanism to deter predators! The coloured leaves of butterflies are an adaptation that has evolved over millions of years. Why are butterflies brightly coloured? A warning Bright colours act as a warning to other…
Hooke’s law states that the amount of force applied to an elastic object is proportional to how far it stretches. However, if the object is overstretched it will not spring back. Hooke’s Law only applies if an elastic object is not overstretched. Objects are made from lots of molecules with bonds between them, if too…
The food available to animals varies depending on where they live. In habitats where food is limited, animals with features or adaptations that allow them to access food more easily are likely to survive more successfully than those without the advantage. Animals with adaptations that allow them to live longer are more likely to produce…
We’ve just broken up for the Easter holidays and I have big plans for lots of fun Easter Science Experiments while everyone is off school. I’ve put together a collection of old favourites, new ideas from us and some great Easter science activities from other bloggers too. If a STEM Challenge is more your thing,…
This simple investigation is great for learning about stretchy materials. The challenge is to find a material that stretches easily and also returns to its original size. Don’t forget to check out my other ideas for learning about materials and their properties too, including sorting objects from Ariel’s cave, creating a superhero cape and saving…
Sublimation is when a solid becomes a gas without turning into a liquid first. There are three states of matter. Adding or removing energy from a substance can change the state it is in. For example water is a solid below 0oC ( freezing point ), a liquid above 0oC ( melting point ) and…
Toothpick structures are a fantastic, low-cost, and easy STEM challenge that keeps kids busy for hours. We used cocktail sticks, but you could also use straws or spaghetti. I set the children a challenge to build a structure that would hold a chocolate egg off the ground. Toothpick Tower STEM Challenge Toothpick structure materials How…
