Exploring Solids, Liquids and Gases (with Oobleck!)
This term in Year 7 Science, students have been learning about a fundamental area of idea; state of matter. We began by investigating the key properties of solids, liquids and gases. We looked at how they move, how they behave under different conditions and why these differences matter in everyday life. We then linked this to the particle model to understand the shape, volume and flow of each state of matter. To put this knowledge into action, I introduced something a bit unusual into the classroom: oobleck! This mixture of cornflour and water is known as a non-Newtonian fluid, meaning it doesn’t behave like a typical liquid or solid. When left alone, oobleck flows like a liquid but when squeezed or struck, it behaves like a solid. Students experimented by poking, stirring, squeezing and even trying to roll the mixture into a ball, observing how its properties changed with force.
Through this investigation, students were able to:
- Apply their understanding of particle behaviour and link practical experience to knowledge of the particle model.
- Compare real-life examples of solids, liquids, and gases.
- Recognise that some materials don’t fit neatly into one category.
- Develop curiosity and confidence through hands-on science.
The students made predictions, discoveries and a bit of a mess! It was an engaging way to explore how science helps us understand the world around us.
We look forward to more scientific adventures as we continue the term.
