Science Week Friday Oobleck

Learning Intention • • Science Week L. I: To observe closely using simple equipment. Steps to success *I can make observations.

Oobleck Recipe • • Here’s what you’ll need to make this oobleck recipe: 200 g cornflour 100 g water Food colouring (optional)

Maths Learning Intentions • Band 1 • L. I. To measure weight. • S. C. I can measure weight using grams. • Band 2 • L. I. To read a scale. • L. I. To choose the right units to measure weight. • S. C. I can read a scale. • *I can choose the correct units to measure weight.

Maths • Use the weights to help you to measure out the amount of ingredients. • What do we measure weight in?

How to make Oobleck • Pour 200 g of cornflour into a big bowl. • Add four drops of food dye to 100 g of water and pour it into the bowl. • Mix the ingredients together with your hands until they are blend.

Observing 1. How does the mixture you have made feel in your hands? 2. Scoop up a handful of mixture Does it stay in your hand or dribble through your fingers?

Experimenting and Observing 3. See if you can make a ball by rolling the mixture between your hands. • Try rolling it quickly, then slowly. • 4. Try pinching the mixture with your hand. Does it feel hard or soft?

Experimenting and Observing • 5. Try to stir the oobleck quickly with a spoon. • What happens? • Record all of your answers on your science sheet.

What Is Oobleck? • Oobleck isn’t a liquid or a solid, it’s a non-Newtonian fluid. At times, it may seem like a solid or a liquid but it acts differently than a normal solid or liquid. Making oobleck is a great science experiment to show changes in pressure can change the properties of some materials.
