BALLOON ROCKET & SLIME

Room 11's celebration of Primary Science Week continued yesterday with two experiments involving thrust and viscosity.




BALLOON ROCKET
To explore the concept of thrust the students created balloon rockets. The rocket balloons zoomed along a piece of string as the air rushed out of the balloon it created a forward motion called thrust. Check out this link for an explanation on how to make your own balloon rocket http://www.sciencebob.com/experiments/balloonrocket.php 


SLIME TIME 



When creating our slime room 11 talked about the concept of viscosity. Fluids like water which flow easily are said to have low viscosity, whereas fluids like cold honey which do not flow so easily are said to have a high viscosity. The slime we made using cornflour created a special type of fluid that didn't follow the usual rules of fluid behaviour. When we applied pressure to the slime, its viscosity increased and the cornflour slime became thicker.
