# [S3] Lesson 36 : Mechanics + (AM) Secret Enclosed – Graphs (Modulus, Log, Expo, Parabola) + EOY – Metals & Redox Updates/Debrief

[S3 Physics PMCians]

What we did in 2 hours:

On 3, 5 and 6 Sept, the S3 PH has come together to complete the following:

1) Secret Enclosed – Pressure Part II

2) The Final Lap – MCQ Qn 19 to 22, Structured Qns

Do remember:

1. P is related to FOC and speed, V is on the average separation distance and T is on the average KE of the particles.
2. P(1) = P(2); same level and same fluid, is the basis to solve questions related to Manometer, Barometer and Hydraulic Press.

Solution to the Remaining Questions are already available to the Folder shared with you previously.

Do remember to check the solution out and feel free to discuss any doubts before or after lesson.

In this coming week (Sep 10, 12 and 13), we will continue our revision with Moments and Work Energy and Power.

Do remember to always bring your Secret Enclosed AND the revision books for all lessons.

Do bring along your calculator for the lesson.

Oh, do remember to spend some time to watch the Additional Lesson 1 video (if you have missed the live zoom on Tuesday).

If you have yet to collect the new book, please collect them by this coming weekend!

Special Mention:

Should you need assistance in your daily practices in Physics, do send your attempted workings and questions to 9005 1733. We will strive to clarify your doubts.

What we did in 2 hours:

This week, we covered on Exponential and Logarithmic Functions. We have seen various question types in the chapter, ranging from simultaneous equations to word problems.

Generally, we recapped:

1) Exponential Functions

a. Indices law

b. The 2-step “S” method for same base/different base

2)  Logarithmic Functions

a. Law of Logarithms

b. Do’s and Don’ts when handling the power n

You may start to try some of the takeaway revision papers set A, B or C (Page 125 to 154). Solutions are already provided for checking.

To supplement the revision we did in class, please try

• Q2 (Page 125)
• Q4 (Page 137)

Special Mention:

In the next lesson, we will be doing some Graphs Sketching.

To be better prepared for the class, you may want to recall these concepts again:

1) Completing the squares

2) Indices law

3) Law of logarithms

4) Basic Trigonometric graphs

See you in class!

[S3 Chemistry PMCians]

What we did in 2 hours:

We have completed our revision on chemical bonding and are now into the chapter of Periodic Table. You are now equipped with efficient thought processes on how to deduce the physical properties of a substance (i.e. strong force = high amounts of energy to overcome = high mp/bp or hard). We have also done a quick summary on Periodic Table trends and were reminded on the reasons we could use to rationalise these trends.

You may now complete the Take Home Package on Chemical Bonding to consolidate your learning and prepare for your EOY with the top school questions provided.

Special Mention:

A quick reminder to complete also Qn 11-13 of your Periodic Table Last Sprint in preparation for class this weekend. We will also be beginning with our revision on Acids, Bases and Salts on Thursday. You may want to recap certain concepts such as acid/base reactions, salt preparation and test for cations/anions/gases before class!
