[S3] Term 1 Week 8 (24 Feb-1 Mar) Updates/Debrief

[S3 Physics PMCians] 

What we did in 2 hours:

In the last lesson, we learnt what it means to undergo free fall and how to work out its acceleration. By now, all of you should be able to plot a graph associated with free fall, to show whether the object is being thrown upwards or being bounced on the ground. We also covered two kinematics tests which expose you to the different types of questions that can be asked. Congrats to those of you who did well or even obtain full marks for test B, you fully deserve a pat on the back and of course a treat (PMC dollars) from us! Full Solutions for Test B is here!

What you take home:

This is an interesting video which illustrates the concept of free fall, and the kinematics equations involved (Warning: only for those who have learnt and understand how to use the 4 equations of motion)

Special Mention:

Next week, get ready for a recap on the topics of Light and Kinematics as we test and challenge your concepts once more, to get you ready for your term exams! 

By the way, you can only truly understand the “Gravity” of your situation once you experience free fall.

What we did in 2 hours:

We started on Polynomial identities. While cubic functions may look intimidating at a start, we can still solve the unknowns easily! We had fun with TWO methods, suitable substitution and comparing coefficients.

• Solution to Quadratic Inequalities Test
• Additional practice, Daily Dose on Polynomials

 Special Mention:

In the next lesson, there will be a Test on Polynomials (concept 1 & 2).

During your free time, try expanding this simple cubic equation y = (2x+1)(x+2)(x+3).
With the answer that you got, are you able to factorize it back as given? We will explore this in the next lesson after the test!

[S3 Chemistry PMCians]

What we did in 2 hours:

We mastered the use of three different formulae interchangeably and practiced basic stoichiometry by using the analogy of the cheese sandwich, focusing on the essential three steps to solving such problems.

What you take home:

Ensure that you are fluent in the use of the three formulae (especially formula #1, #2 and #3 in the summary) by practicing additional questions in the Take Home package till Pg 7.

Special Mention:

Be prepared for a quick Kahoot quiz this coming week on moles and stoichiometry!   A reminder to bring along your Weighted Assessments for chemistry for a quick feedback and review session with your tutor before or after class!

Thank you.”
