# data[].attributes.body
Arrange the steps in a logical sequence. Post a photo of your procedure in your group's workspace.

What are the similarities and differences between your group's and other group's protocol?

# data[].attributes.body
Carry out the procedure you have planned.

Post a picture of each stage/step that you have carried out.

Records the following observations:

1. What do you observe about the liquid in the flask?

2. What has happened to the balloon?

3. What causes the formation of bubbles in the flask?

Instructions: Take photo of your set up at the 0th, 5th, 10th, 15th and 20th minute. Insert the photos of the set up in the padlet, under your group name. Insert more slides on your own, if needed.

# data[].attributes.headline
As a group, what do you think is the cause of your observations today? Name this phenomenon (that caused the balloon to inflate).

The balloon is inflating slightly.

# data[].attributes.body
Hi

W'sup

# data[].attributes.body
Balloon inflated a bit.

We think it inflated because the yeast was growing and pushing the air to inflate the balloon.

# data[].attributes.body
Longxu is eating sugar water. - LOL

The yeast water is blurry and yellow.

# data[].attributes.body
We just put the balloon on the Erlenmyer flask.

# data[].attributes.body
Just completed step 6!! Balloon is inflating...

# data[].attributes.body
LOL

# data[].attributes.body
Picture

# data[].attributes.body
Some air bubbles formed.

We think it was because when the yeast was growing it produced carbon dioxide

# data[].attributes.body
1. There is a bit of bubbles in the liquid .

2. The balloon is starting to inflate.

3. We think that the yeast is making the bubbles and the bubbles is making the bubble inflate.The bubbles increase as the balloon becomes more inflated.

# data[].attributes.body
We are restarting.

# data[].attributes.body
Some bubbles are forming in the flask. Our group thinks that the yeast is reacting to the sugar and is creating bubbles.

# data[].attributes.body
There are air bubbles forming on the water.

The water is murky.

Why?

We followed the protocol.

Phenomenon:

As the yeast feeds on the sugar, it produces carbon dioxide. With no place to go but up, this gas slowly fills the balloon. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough.

# data[].attributes.body
Balloon starts inflating

# data[].attributes.body
The balloon did not inflate. The theories are:

1. The water level was too high.

2.The water was too hot.

3.We did not use enough yeast.

Therefore, we will restart the experiment.

# data[].attributes.body

# data[].attributes.body
Longxu is stirring stuff together.

The balloon is inflating a lot.

# data[].attributes.body
At 2:55 we discovered that our experiment was wrong, as scientists, we decided to restart the experiment.

# data[].attributes.body
Balloon got even bigger.

Balloon was rising too.

# data[].attributes.body
The balloon has finally inflated!!!

# data[].attributes.body
Longxu became yeast bae.

# data[].attributes.body
After trial and error, we finally inflated the balloon!

Because we followed the protocol

# data[].attributes.body
Success!

We think it's because we followed the protocol!

# data[].attributes.body
We are so happy to have our balloon inflated.

# data[].attributes.body
The balloon is slowly growing bigger.

Longxu is still stirring.

# data[].attributes.body
We are posting for no reason. We think it's fun.

# data[].attributes.body
The balloon grew bigger.

# data[].attributes.body
Now the balloon feels very inflated and we are happy that we have suceeded this time.

33th minute - Observation (The scientific name of phenomenon)

Ans: Fermentation

# data[].attributes.body
1min - The glass starts to bubble

5min - More bubbles start to appear

10min - The balloon starts to appear

15min - The balloon starts to straighten itself

26thmin - The bubbles reached the top!

35thmin - The balloon became fatter!

# data[].attributes.body
Jared is not in picture

# data[].attributes.body
because......... we are not sure of the protocol to follow.

# data[].attributes.body
something scientifically fantastic

Longxu got water in his clothes. LOL

# data[].attributes.body
The balloon keeps rising and more air bubbles formed. We think it's because the yeast is still growing

# data[].attributes.body
The balloon is huge.

# data[].attributes.body
There are more bubbles in the flask as the balloon grows more inflated.

# data[].attributes.body
How do you feel, as compared to last week?

-Do you think that following the protocol is important?

-How can I work better as a group the next week?

1. Name -

2. Name -

# data[].attributes.body
More air bubbles are forming and the yeast is still growing.

# data[].attributes.body
we feel even worse than last week.

# data[].attributes.body
Finally in the picture!!!

# data[].attributes.body
The air bubbles are still rising and the yeast is still growing.We don't know when it will stop growing

# data[].attributes.body
We feel that following the protocol is essential as when we do not follow the protocol, things might go wrong. As a scientist, we should always follow the protocol so that we do not waste the materials. We think that we can improve on our behaviour and work as a team.

# data[].attributes.body
This phenomenon is called fermentation.

# data[].attributes.body
1. Longxu

1. I feel that we were horrible last week.

2. I can work better by having fun while learning.

2. Elliot

1. I feel more horrible because our balloon was not inflated last week.

2. I can work better by listening to others opinion and having teamwork.

3. Tze Jay

1. I feel that we were horrible last week.

2. I can work better by follow the protocol no matter what.

# data[].attributes.body
As the yeast grew, the air bubbles were pushing the air into the balloon, causing the balloon to inflate more and more over time.

# data[].attributes.body
The balloon grew even bigger. We have emptied it.😭

# data[].attributes.body
'There's still something sticky'

Quote from Longxu

Bye!

# data[].attributes.body
We should try again, but not mindlessly. We should follow our protocol.
