Mulyan Science Day

On 16 August nine students from Cowra High assisted with the science activities run by the teachers at Mulyan Public School.  In all there were a total of six activities for the day.

The first activity for the day was the milk explosion which was Science and Art combined.  Our students placed food dye in some milk and then the Mulyan students dipped a cotton bud soaked in detergent into the milk.  They then placed some absorbent paper towel over the bowls with their beautiful colour explosions and peeled it back revealing a coloured pattern.

The next activity was turning the milk into plastic.  Our students assisted in distributing the warm milk and the Mulyan students then stirred their vinegar milk mixture until it became lumpy, and then sieved it.  Once all the liquid was gone, our students assisted in drying the lumpy milk by squeezing the liquid out of the casein and then letting it dry until it became hard.  

The Elephant's toothpaste was very popular.  Our students assisted in doing the safer version of the experiment, mixing  yeast with water and then giving the ingredients to Mrs Statham who was demonstrating the more powerful version.  The more powerful Elephant's toothpaste initially fizzled, but luckily the Science department from Cowra High came to the rescue and was able to supply a secret ingredient to make it work a little better.

Building the Tallest Tower with only raw spaghetti sticks and marshmallows was the stickiest experiment of all.   Students helped the Mulyan students design and build their tower. 

The final activity of the day was the egg drop.  Our students helped blow up balloons, glue things together and drop the vessel from a height of two metres.  Their design had to save the raw egg that was placed in it.  

It was an excellent day and the students had a great time not only with some of them seeing their old teachers again, but also with the activities. Congratulations to Megan Carroll, Jacob Walker, Sophie Light, Lucy Sutherland, Emily Whatman, Tahli Holmes, Nicola Carter, Jade Brown and Erika Sullivan for working so well with the Mulyan students and their display of respect and responsibility.
