[S3] Lesson 19 (11-17 May) Updates/Debrief

[S3 Physics PMCians] 

What we did in 2 hours (PMC LIVE):

In the previous tutorial (7, 9 and 10th May), the S3PH cohort gathered with the respective tutor to embark on the first tutorial discussion for Work and Energy. The main focus of the tutorial was on the importance of the COE equation (i.e.: KE1 + PE1 + WD (F) – Energy Loss due to Friction = KE2 + PE2) and how we could apply this question effortlessly to solve questions. 


The tutorial session concluded with our usual 4Q and kahoot discussion.


What we received:

For this coming tutorial (14th, 16th and 17th May), we will once again gather to sharpen our 3 concepts learnt in the topic of Work Energy and Power. We will be playing some games to end off the discussion and of course, many points are waiting for you to claim!! Hence, do remember to complete the WEP Lesson 2 via the Teachable Website before you attend the lesson this week.


Special Mention:

Though we may not have our usual face-to-face sessions where you could stay back to ask your tutor questions, we are always here giving full support to your learning in Physics. So, if you have any question(s) to ask, feel free to send them to 9100 1235(PMC HQ). 


Do remember to download the PMC.sg app via the IOS Apple or Andriod store.

With that, continue to stay home and stay safe.

[S3 Maths PMCians] 

What we did in 2 hours (PMC LIVE):

We understood how the equation of a circle comes from. In fact, it’s so easy to understand that it comes from the ‘distance’ formula we learnt in coordinate geometry!


To sum up what we have learnt:

  • finding the centre and radius of a circle from general/standard form
  • forming an equation of a circle with centre and radius
  • the horizontal/vertical tangents of a circle, and why it is so useful
  • applying other concepts from coordinate geometry.


We did a warmup chat challenge and had seen that the questions in this chapter can be set in many ways! While the questions coming from this chapter may not be easy to interpret, sketching the diagram always help!


What You Received:

Please click the link here for the solutions to the sections below:

  • Solutions to Takeaway Questions (Equation of Circles)
  • Solutions to Test A (Equation of Circles)


Special Mention:

We will continue to explore on more question sets, including reflection of a circle. Please continue to watch the webcast lectures and complete all 4 concepts on Equation of Circles. We will then team up and engaged in our breakout room challenges. See you in PMC LIVE!

[S3 Chemistry PMCians]

What we did in 2 hours (PMC LIVE):

We mastered qualitative analysis by examining precipitates through ionic equations and how known cations react with unknown anions (and vice versa) to give us unique observations, allowing us to deduce the identity of unknown substances.


What you received:

We have now completed the topic on qualitative analysis and you should be able to complete the Take Home Gems. Do make use of holiday time to revisit the solubility table, reactions of acids and bases & tests for cations, anions and gases. These form the bulk of your foundations for Chemistry!


Special Mention:

Did you know that fireworks are based on the fact that different metals have different colors when heated? It allows us to recognise them but more importantly create beautiful fireworks we enjoy from time to time!


Stay healthy, stay safe, see you this weekend!
