Wild Chemistry Ride 3 (part 2):


After the Sunken Treasure experiment, I learnt much more about carrying out a proper scientific experiment through a fun and meaningful way. For example, I learnt the difference between "observations" and "data collection": observations are the what you observe (such as see, hear, smell etc.), while data collection is about gathering and measuring information (such as the volume of gas collected in a gas syringe etc.)

Some scientific concepts I have learnt are when hydrogen peroxide (which I found out later was Solution 2) and the carrots' catalyse are physically combined, gas will be produced. Also I discovered that by chopping up the carrots into small pieces, the exposed surface area of the carrots to the salt and sugar solution will be increased, thus the reaction will occur within a shorter period of time.

Overall, I felt that my group worked together very well, as we each were given a role in the team, for example two were in charge of taking pictures and recording down observations and data, two were in charge of preparing the experiment apparatus and chopping up the carrots into very small pieces, while another group mate and I were mainly performing the experiments. However, all of us still contributed ideas to our plan and our teamwork was what I thought helped us in achieving success, and I am thankful for that.

On the other hand, my group mates and I could be less distracted by other things like playing around with the balloons, and also be less careless like when we often forgot to pump the air out of the gas syringe before using it again the next try.
