Science Week
Science Tabloids
Last week was science week, on Wednesday the
15th August; Wattle Grove Primary School held a Science Tabloid. In
each tabloid we learnt about and performed science experiments.
My group did a Leak Proof Bag Experiment with
our music teacher Mr Honey. We poked a pencil through a bag filled with water. All
of us expected it to trickle out but it didn’t because the bag is made of
polymers which are tough and flexible. So, when we poked the bag the molecules
hugged the pencil making the bag not leak.
Our second rotation was with Ms Agar where we
did DIY Red Cabbage Chemistry. We used a dropper to get a maximum of 5 drops of
each ingredient in the 5 tubes. In each tube we added vinegar, dish washing liquid,
lemonade, baking soda and red cabbage juice. We then put pH strips in the tubes
to test the pH level of each liquid.
Last but not least, we made a Lava Lamp with
Miss Zaffino. For this experiment we used oil, food colouring, water and Alka Seltzer
tablets to make it fizz. First, we got a glass filled with water and oil. Then added
a few drops of food colouring followed by the Alka Seltzer which caused
bubbling.
In summary, we learned some new facts about
science while having fun.
