[S4] Lesson 23 (Measurement & Mass Weight Density Final Revision + Polynomials + Periodic Table )

[S4 Physics PMCians] 


What we did in 2 hours:

Over the live tutorial sessions (June 6 and 7, 2020), we came together to embark on our revision of all topics using the Secret Enclosed (SE). Do remember to always have the SE with you for all lessons from now on.


The tutors were happy to see that many of you were actively engaged in strengthening your mastery in through our discussions. It was really a pleasure to see such positive learning culture in our zoom room. Let’s keep up this positive vibes!! 


What you take home:

In this coming week (June 13 and 14, 2020), we will come together to continue catching all our secret enclosed summaries. 


We will be doing Kinematics for this coming week! Do note that no documents will be uploaded to the Teachable Website. 

Special Mention:

To all our students taking the GCE ‘O’ MT papers, focus hard for the next two weeks to ACE the papers!

What we did in 2 hours:

We started on Polynomial Revision. We had fun with two methods, suitable substitution and comparing coefficients to find the unknown in polynomial identities. We form equation using factor and remainder theorem and went on to solving cubic equation. Apart from these, we also tackled various question types which involve simultaneous solving and discriminant.


What you take home:

20min Polynomial Test


 Special Mention:

Please note that there will be no webcast as we will be continuing our live lecture on binomial theorem revision. In the meantime, please continue to stay safe, stay healthy and stay cheerful!

What we did in 2 hours:

We have completed our revision on Periodic Table trends across periods and have kickstarted our exploration to trends within a Group for Group I, VII and 0 as well as transition metals. Recall the big idea of the relationship between distance of valence electrons from the nucleus and electrostatic forces (hence ease of losing/gaining electrons) to explain reactivity of elements.


What you take home:

Do continue to make use of the Take Home Gems to consolidate your learning of the chapters covered. Take some time to begin revising on moles which will be our revision topic after Periodic Table.

Special Mention:

We have a love and hate relationship with moles but with our upcoming revision, I’m sure all of you will be so much more confident with this chapter. Here’s an infographic:
