Billowing balloons experiment

Billowing Balloons Experiment
W.A.L.T write a specific question and make a prediction
for a chemical reaction

Does baking soda and vinegar push the air up enough to pump
up a balloon?

Prediction: We think that when the vinegar and baking soda mix
together they will create the reaction and fill up more airspace
and push up the balloon

50 ml of vinegar
½ of a balloon filled up with white baking soda
Clean bottle that is l litre

1 Pour the vinegar into the bottle
2 Get your funnel and use it to pour the baking soda into the
balloon so it is half full
3 Hook the balloon onto the 1 litre bottle without pouring any in
yet so you can secure its place.
4 Pour the baking soda from the balloon into the bottle and watch
the balloon slowly fill up with air.

Results and conclusion.
The balloon inflated/expanded because when the reaction
happened the gas could not go anywhere except to the top
and since the balloon is the most stretchy part it pushed up into
there pushing up the balloon and making it blow up.

The chemical reaction to this is CH3OOH+NaHCO3 >Nac2h3O2
(vinegar) (baking  soda) (sodium acetate) +H2O (water)
+(O2(carbon dioxide)

Sodium acetate and water and carbon dioxide was created
during this process This is an irreversible change because
it can now not turn back into baking soda.

Conclusion : In conclusion the baking soda and vinegar
reacted and pumped up the balloon.

Stack'em Writing recount (Camp)


“Group 7 Stack’em with Ash” “Yes!” I thought to myself. On the second day of my exhilarating journey at camp my group had an activity that i was anxiously waiting for … Stack’em. When we walked over there we met our instructor for the session. It was pelting down with rain and it was arctic in the wind. I could see all the equipment set out in place ready for us to use and it was soaking wet! When we all gathered up she told us the basic rules of how to put on your harness, your helmet and the safety rules. We also had to get into partners so that when one buddy is stacking the other one would be cautiously bringing up the next crate with a pulley hook the other crates.

The main rules were Never walk near the crates when being stacked unless you are of course the stacker or their partner, when she says cleanup crew walk in and gather all the crates that have scattered across the floor, Make sure all equipment is on properly and never leave captain hook dangling in the air. I was up second. I anxiously put on my harness and watched nervously as the one group before us had bravely started to stack up the wobbly crates.

My heart pounded in my chest my legs shivered with anticipation. I was as ready as ever. I took a deep breath calming my body down. First crate was easy and one by one i stacked a crate on top of the other. My hands and legs were nervously shaking; yet I still had some confidence and felt a little brave. The tower swayed and rocked around like it was trying to shake me off. I carefully balanced myself, although I tried not to look down (I might've had a small fear of heights).
“Yes all the way to the top!” I thought, once I had finally stood up on the last finishing crate. I braced myself as i jumped off the tower of crates watching as it plummeted towards the ground ending with a big “Crash!’ I was slowly lowered towards the ground with a sigh of relief escaping my body.

I unhooked my harness and I was glad to not have a wedgie anymore! I watched for the rest of the time as my other group mates stacked up the crates conquering their fears or accomplishing a goal they had made earlier. I also helped bring up the crates to my buddy and he made it all the way to the top as well.

Overall, this was an amazing, breathtaking experience and I new that as soon as I finished I would treasure this memory; feeling happy and proud of what I had accomplished.

This piece of writing shows that i can use a little bit of complex punctuation in my writing.

Chameleon Report

The Amazing Features Of

Have you ever wanted to use your long sticky tongue to grab the remote or to use your camouflage
body to play hide and seek? Well too bad chameleons have it lucky. Chameleons are part of the
family chamaeleonidae. They are from the reptile family. There are approximately 160 species of

Chameleons are approximately 15 mm .They have long sticky tongues, four fast small legs, scaly
hard bodies and large encased eyes. It also can turn the colors pink, green, turquoise, blue, orange,
red and yellow. Depending on its feeling it changes color. Like angry is a dark color and light colors
might want to attract mates.            

The chameleon can be found in the desert and rainforests habitats. The main found places of
chameleons are in europe, asia, africa and north america. They adapt to their habitat very well.

Using all of its body parts each part has a very useful function to help the chameleon stay alive.
Chameleon can run 33 km per hour using its fast agile legs. Its long sticky tongue launches out of
his mouth to quickly snatch their prey. The tongue sticks to the prey and is quickly retracted into
its mouth. Also its eyes have a 360 view to see everything happening around it. A chameleon's
skin can change color also too adjust to temperature or light. As another bonus it doesn't have to
be one color so it can be multi coloured or patterned perfectly to camouflage away from its predators
.Using their skin, they can also be used to gain heat with black skin

Overall chameleons are outstanding eye catching reptiles. They can blend in, show their moods
through color appearance and have an interesting way to catch prey. Chameleons have amazing
abilities. Do you now want to change your DNA? Of course you would be able to change color but
you would have to eat bugs and insects for the rest of your life. Just the life of a chameleon  Image result for chameleon purple tongue

I think that we did well with paragraphing and also using a lot of detail.

I think we could work on scientific reasoning and terms
