The Billowing Balloons Experiment

Billowing Balloons Experiment


W.A.L.T: Write a specific question and make a prediction for a chemical
reaction


Question
How fast will the balloon inflate when the baking soda and white vinegar mix?


Hypothesis
I thought that the balloon would inflate fairly quickly - Rohan
I thought that the balloon would inflate quite slowly - Theodore
I thought that the balloon would blow up and pop - Ashraf


Experiment
Equipment:
50 ml of white vinegar
½ a balloon of baking soda
1 Funnel
1 Teaspoon
1 balloon
1 L water bottle, fairly clean


Steps:


  1. Pour 50 ml of white vinegar into a 1 L bottle.
  2. Next scoop in baking soda into the balloon until it gets half way full.
  3. Precisely place the balloon on the 1 L bottle but don’t let any baking soda
  4. fall into the bottle
  5. Let the baking soda fall into the 1 L bottle and watch as the balloon inflates
          but does not pop.

Results:

The balloon inflated because the gas released from the chemical reaction

escaped into the balloon, making it inflate slowly.  This reaction is irreversible

therefore the sodium acetate, water and carbon dioxide cannot transfer back

to vinegar and baking soda.  The chemical compound was:

CH3COOH + NaHCO3 → NaC2H3O2 + H20 + CO2

    (Vinegar)        (Baking Soda) (Sodium Acetate)  (Water) (Carbon Dioxide)


Conclusion:


The baking soda and vinegar inflated the balloon quite slowly.

Year 6 Camp Recount

Year 6 Camp Recount


Beep, beep, beep!  I abruptly sat up and snoozed the blaring alarm.  I was deep in my
thoughts when I forgot one very important thing.  Hmm, what could it be. Then it hit
me: it was camp today! I hurriedly forced my brother and mother awake and got
dressed in my mufti attire.  Swiftly, I made some breakfast, got ready for school and
waited impatiently for my mother to dress into her clothes. It felt like hours had passed
but it was only roughly ten minutes when my mother bursted through the door and
ordered me to bring the suitcases downstairs.  With that thought in mind it re-energized
me to bring the suitcases down the flight of stairs. Most of the descent was fine except
the occasional bump. We got to the car and drove to the school with high spirits.
At last we arrived.


I unloaded the suitcases and ran to school in glee and excitement to the class.  Leaving
the suitcases outside as we were instructed by the teachers yesterday I waited patiently
accumulating more and more room twenty one students outside the classroom.  We
waited until the bus arrived and gather around our teacher: Ms Mistry to tell us what
to do. “Go to the bus and wait outside until they let you enter and also i’ll be right
behind you, thank you” she informed.  Courteously, we walked to the bus and entered
in anticipation of the quality of camp. It took about forty minutes mut we finally got
there. We put our suitcases in the dormitories that we were told to sleep in for whole
of camp.  Settling down, we learnt about the marine life and marine reserve and got to
see a jar full of rubbish they had collected from the sea and the shore. After that we all
went to the hall and lined up in our groups to get told what activity we were going to
do first.  My group members were: Rachita, me, Measum, Marcus, Sahil, Ella, Nicole,
Alisha, Yohanna, Ameena, Sandhya and Nidheesh.


We got stak’em so we headed toward the stak’em crates and waited for instructor; Ash,
Ashley or Ash Burton as people called her and learnt about the full body harnesses and
how to put them on.  We also learnt about how to stack the crates and use the pulley,
we also got numbered of in pairs for the turns. We all waited for our turns so we all
told riddles to ash while Rachita made nicknames for mostly everyone.  The nicknames
were: Mr Tomokino the Cappuccino, Ra Ra the Banana, Row Row Row Rohan,
Wriggly Worm Ameena, Yo Yo Yogurt (Yohanna), Wriggly Worm 2 Measum, Jenga,
\ Miss Tree, Sa the Hill, Ella the Hill, Nickelodeon, Cold (Alisha), Elephant (Alisha)
and Nidheeshina.  It was finally our turn, *gulp*. I clipped my harness and grabbed
a crate and kept stacking until 7 because I was scared of heights. I was scared to jump
of but Nicole gave me a count down and I jumped off and kicked the pile which was
actually considerably fun for it being a heights thing.  I rejoiced and uses the pulley
for my partner which was Measum and he got all 13 crates. We finally finished the
nerve racking experience and went back to the meeting place. I had to agree with
myself; it was the best experience of my life and it should be for anyone else who went.
