Billowing balloon experiment

Billowing balloon experiment


Walt: write a specific question and make a
prediction for a chemical reaction


Question: Is the gas that is created by the vinegar
and baking soda going toblow  the balloon?


Hypothesis : The gas is going to blow up the
balloon.


Experiment-
  • Bottle
  • Vinegar
  • Baking soda
  • Deflated balloon
  • Funnel


Step 1- First, put  the vinegar in the bottle.
Step 2- Carefully place the funnel on top of the balloon and fill it  half with baking soda.


Step 3- Then place the balloon on the bottle top
and turn it so all of the baking soda goes into the
bottle.


Results- The deflated balloon expanded because
the gas did not have anywhere else to go . The
 vinegar reacted with the baking soda to produc
e the following reaction:


CH3OOH + NaHCO3 = NaC2H302 [sodium
acetate] + H2O[water] + O2 [carbon dioxide]


This was an a irreversible change.


The products that were formed was sodium
acetate ,  water and carbon dioxide


Conclusion- the balloon expanded because of
the gas that was released.

giants Ladder

favourite camp activity


WALT: understand the purpose for writing ,
and the processes and features appropriate for
the purpose.


“Another day at camp” I thought as I woke up that day .  
Time was going fast until we found that we were doing Giants
Ladder, I was so excited .  They told us to stand by the Giants Ladder
, so we all did. They told us that the anchor and climber are like in
Rock Climbing , like what you have to say.


The instructor told all of us the safety information and instructions
on what to do.  Also you had to wear your harness like in climbing.
The other type of harness was a body harness it is for you whole body
so you are more safe.


Now we were ready to climb.
I was so excited .My buddy for Giants Ladder  was Nidheesh .
The Ladder steps got narrower as we got higher.  Me and my buddy
help each other to get to the top . We had to bend our knee and
 they stand on it . we got to the top . I said to myself “YES” They
told us to get down like a Monkey.


I really enjoyed and had a great time at Giants ladder. I feel like
doing it again.


I like how I paragraph my ideas.
