[J2] Term 1 Week 8 (24 Feb-1 Mar) Updates/ Debrief

[J2 Physics PMCians] Becoming a Pro in Electricity

 

What we did in 2 hours:

We started our journey to demystify this new topic of Electromagnetism (EM). 

The 2 main lessons you would have taken away with you are:

1) use of Right hand-grip-rule (RHGR) to determine the direction of Magnetic field created by a Current, including the special shortcuts!!

2) use of Fleming’s Left-hand rule (FLHR) to determine the direction of the magnetic force, and calculate the magnetic force, F = BIL.

Direction of Magnetic Field (Bar Magnet)

Special Mention:

Next week we will continue to build on the concepts laid this week. So, if you missed this week’s foundational concepts, please sign up for the digital lesson before the next lesson!

[J2 Maths PMCians] Vectors Revision

 

What we did in 2 hours:

Full course on Vectors! Line and plane operations make up the bulk of vectors questions, which put to test our knowledge on intersections, angles, and point to line/plane evaluations. Do touch up on all required operations and put them into practice!

 

RI Class: DE application questions are quite a handful and having cleared them that concludes our topic on Differential Equations.

What you take home:

Worked solutions for Vectors Try-It questions as linked:

Special Mention:

Complex Numbers revision begins this week! As always, it will help to be warmed up before the class.

RI Class: We move on to vectors revision. Do clear out some of the rust!

[J2 Chemistry PMCians] Get ready for a world of organic chemistry!

 

What we did in 2 hours:

[Paya Lebar/Beauty World] We have completed Hydroxyl Compounds and begin looking at reactions involving Carbonyl Compounds. We have looked at

  1. Acidity of Organic Compounds
  2. 6 reactions of carbonyl compounds (1 more to go)
  3. Nucleophilic addition mechanism

 

[Bishan] We focused on the main reactions and concepts of Halogen Derivatives. In specifics, we looked at:

    1. nucleophilic substitution mechanism (SN1 and SN2)
    2. distinguishing test for halogen derivatives
    3. ease of hydrolysis of halogen derivatives

What you take home:

[Paya Lebar/Beauty World] You should have received the “Take Home Questions” and “Everything you need to know” series for Carbonyl Compounds. The solutions to those and additional structured questions are found here:

This week, we will complete carbonyl compounds and move onto Carboxylic Acids & Derivatives.
