Science Reflection (#FailWell)

I felt really disappointed when I got my science exam back. This is because I made really silly mistakes in the exam which could have easily been avoided during the exam if I wasn’t feeling so cocky and confident during the moment. After the exam, I felt like I did well during my exam, but my results state otherwise. I am pretty sure that this is the worst science test that I have taken in the whole grade 9 course, usually I ace the tests, or get 92% at the lowest, but in this test I only got 91.2%. A lot of people will say “oh you did so well”, well I think otherwise, I think that I did pretty bad and I could have done much better.

Two things that I have learnt about exam techniques, specifically science exams, is that the only thing that is actually needed for a science exam is the keyword. As long as you know the keyword, and you know how to phrase it into different sentences, you will be guaranteed full marks for the question. This was shown in the first question itself, I lost a mark because I didn’t state the keyword that was needed for the answer – the solution is more dilute than the leaf – instead I wrote – the solution has a higher water potential than the leaf – which didn’t give me the mark as I didn’t state the necessary keywords needed. The second thing that I have learnt about exam technique is that we always have to be accurate with our reading, there usually won’t be a range of different answers when the question asks for a reading. This was shown in question number 3, where I somehow managed to get the reading off by .1, even though the scale was right in front of me. I have made this same mistake in a few of my science tests, and I honestly don’t know why I keep getting the readings wrong, maybe I just need to focus and be more in the moment when taking exams.

As I stated in the previous paragraph, keywords are EVERYTHING in science, and I mean everything. The only way to get marks in science is by getting the correct keywords, even if you explained the question properly, you won’t get marks unless you have the specific keywords. In biology, if the question asks you about plant cells put in water (or something within those lines), then osmosis is guaranteed to be one of the keywords. A few other keywords for these types of questions will be – dilute/concentrated, water potential, down a water potential gradient, into the cell/out of the cell. For chemistry, if the question is talking about the rate of reaction then a few keywords will be – collisions, more/less frequent collisions, activation energy, successful collision. If the question is about physics and about things like force and acceleration, you should always remember that if the forces acting on an object are unbalanced, then the object will accelerate at a constant rate, it will not accelerate and an increasing rate.

3 specific mistakes that I have made which shows misunderstanding in 3 concepts are:

  1. (5a) I wrote that oxide is OH instead of O. This was a misunderstanding as I thought that a hydroxide and an oxide were both the same.
  2. (3dii) I wrote that since the values don’t go up by the same ratios, they are not directly proportional, but my misconception was that we need to use the evidence given to us, such as the table, and that we have to be more specific about how the data values show that it is not directly proportional. An ideal answer to this question would be the data values in the table show that the values for Power do not double as the values for Current doubles. My main misconception in this question is that I thought we didn’t have to be specific, so I made my answer very broad.
  3. (8biii) In this question, I wrote that a difference between boiling and evaporation is that boiling produces bubbles, while evaporation does not. For some reason, I thought that this would be a valid answer but turns out that this is not, and that my answer is incorrect. The correct answer, in this case, would be evaporation is only happens at the surface, while boiling happens throughout the liquid // evaporation produces cooling, while boiling does not, etc. My main misconception was that I thought that boiling producing bubbles and evaporation not producing bubbles would be a legit answer.

Looking forward, there are many things that I have to keep in mind. I always have to remember to focus on the exam and to stay in the moment so that I don’t make silly and unnecessary errors. Another thing that I should keep doing in the future is past paper questions. For this exam, I felt pretty well prepared, but I didn’t do as well as I expected, but in the future exams, I will do much better by practising even more with past papers.

C2 TEST REFLECTION

We received our C2 – Structure and Bonding test back last week, and upon getting my test I was disappointed. Despite getting a good grade, I made lots of silly errors which I could have avoided if I had double checked my work. In total, I lost 5 marks, all in section B of the test.

In question 9c, I lot 2 marks because I wrote tetrahedral ionic instead of simple covalent. This wasn’t really a misunderstanding or a misconception, I just didn’t double check my work and I let my pride get the best of me, therefore I lost 2 marks by making that silly error.

In question 11c, I lost one mark because I didn’t specify a legit reason for why diamond is a very hard substance. I think that the reason why diamond is a hard substance is because each carbon atom in diamond forms 4 strong covalent bonds, forming a tetrahedral structure which is very rigid, therefore causing diamond to be very strong. I think the main reason why I lost a mark on this question is because I wasn’t really clear as to why diamond is very strong, even before the test.

In question 12c, I lost one mark because I wasn’t so sure about how the answer was meant to be structured, and I didn’t really know how to answer the question. I think a proper answer to question 12c would be because the electrostatic attraction in Lithium Oxide is greater than that of Lithium Chloride, therefore Lithium Oxide needs more energy to break the electrostatic attraction.

In question 13c, I lost one mark because I didn’t use the correct terminology. I feel like if I used the words, ‘destroy the intermolecular forces’, then I would’ve gotten the mark.

Overall, I could have avoided all of these silly mistakes and gotten better marks if I double checked my work.

Bonus: Chemical bonds are the INTRAmolecular forces, the forces within a molecule. It is the forces that bond to atoms together, forming a new compound. INTERmolecular forces are the forces holding molecules together, changing the state of matter that the compound is in.

C1 test reflection

okay, so today we got our C1 test back, and on receiving my test i felt really happy and satified as i got the grade that i wanted, and i did as well as i expected.

i was pleased to see that for question 3aii, i changed my answer from chlorine is a gas to chlorine is a metal, earning myself a u.

i could have explained my questions better and not be so nervous about getting my test back. i answered my questions with too much writing, and i could have minimalized my writing somehow.

for next time i need to remember to not stress about these little tests, and to study very hard so that i will do well on my other tests too.

i will fail well by eating ice cream being happy.

Mini-reflection (science)

okay so we got the grade back for the mini quiz and my feelings about the grade I got is 🙁 because I usually do really well in science, and to think that I lost marks because I didn’t use a ruler is pretty funny and it makes me feel 🙁

something I did well is that I used observations to answer question 2.

something I should work on is using a ruler.
