Workshops by Dr Angela Stott on equations of motion and related graphs

Doctor Angela Stott presented a very useful full day workshop to teachers on equations of motion and related graphs. The focus was on the subject matter, as well as the methodology on how to get understanding across to learners. Doctor Stott prepared a box of teaching aids for each teacher plus a set of posters that they can use in their classrooms.

We thank Dr Stott for her knowledge, experience and very kind way of helping our teachers. 

The training was sponsored by the Free State Department of Basic Education and here are the teachers who have attended on 25 June 2015.

Tonight's triangle in the sky!

Today, Saturday 20th July, the crescent moon forms part of a lovely triangle with Venus (bottom right) and Jupiter (top right). This picture was taken at 18:45.

Jupiter and Venus are the brightest “stars” in our skies this month. Keep an eye on them for the next few weeks. They will move closer together and pass each other at the end of the month. When the moon orbits back into this part of the sky (18th July), a similar triangle will be seen, but with Venus above Jupiter.

Memo correction and clarification: Grade 12 P2 Q1.9 & Q6.2 as well as the grade 12 practical paper Q1.5 & Q1.8

An important correction and explanations applicable on the grade 12 chemistry examination and practical papers are available. Click here to download a one page pdf file to obtain this.

Memo clarification: Grade 12 P1 Q8.6

An answer expressed in "cent" is acceptable.

Memo clarification: Grade 12 P1 Q5.5.3

The following answers are not acceptable:

• To the left
• To the right
• Perpendicular to the surface of the tower

Memo clarification: Grade 12 P1 Q5.5.2

The main idea of Q5.5.2 is to calculate the normal force; the correct subscript for the "f" is not the main issue. Hence, accept a friction formula if the "f" does not have a subscript or even if the subscript is "s" instead of "k".

Memo addition: Grade 12 P1 Q3.2

Important considerations to take into account about correct and incorrect presentations of the formula for conservation of mechanical energy.

Memo addition and re-allocation of marks: Grade 12 P1 Q4.2.4

The marks in the memo were re-allocated as follows:

If velocities are compared, accept the answer.

Option 1

Option 2

Memo addition: Grade 12 P1 Q4.2.2

If gradients are used, accept the answer.

Memo correction: Grade 11 Q8.1.2

Answer is 4, not 6.

Memo additions: Grade 12 P1 Q3.2

In view of the fact that this is an isolated system, accept additions 1, 2 and 3 below for full marks, because the mass does not influence the required speed.

BUT

• If 1,59 kg AND 1,6 kg are used in the substitution step, maximum 3/5 if everything else is correct. See example 1.
• If any other mass is used in the substitution step instead of 1,59 kg and/or 1,6 kg, penalise each error as indicated in the memo.

Memo correction: Grade 11 Q7.2

Correct answer is 9,38 x 10^7 m/s (9,375 x 10^7)

Memo correction: Grade 11 Q9.3

Originally an errata was sent to schools that the pressure must be 149,58 kPa and NOT 149,58 Pa. The memo does cater for this situation if the message has not reached all teachers.

Unfortunately, the mass of the gas was given as 0,348 g in the Afrikaans paper and 0,384 g in the English paper.

Please use the following to address this error:

If a learner, after doing this, concludes that the gas is not diatomic, just ignore.

Additions/corrections/etc. to June 2015 memoranda

Additions, corrections and other relevant comments will be posted on this blog during the period of marking the June 2015 question papers.

Visit the blog on a regular basis to check if new information is available. The best way of doing this is to subscribe to the blog. You will then be informed by email when new information appears. Refer to this post for instructions on how to subscribe.

If you see something that is not covered by the memoranda, you are welcome to send an email to the blogmaster for inclusion on the blog. It will be highly appreciated and will help other colleagues.

Today the marking of the June examination papers will start. Best luck with all of that. 

Key concepts: Accuracy, consistency, fairness! 

Very important
As soon as you are finished with a specific grade, email your electronic mark sheet to your subject adviser. 

UPDATE: IBP memo discussions of grade 12 June papers

The full information is as follows:

Grade 12 P1 (Physics): 17 June from 09:00 until 11:00

Do you need apparatus and chemicals?

Edutrade gave a lot of support to the Free State Education Department in the past. All the kits that were distributed to schools in 2013 were supplied by Edutrade.

Feel free to contact them at this web address for a complete catalogue, with contact details, if you need apparatus, chemicals, etc. It is important that school management teams budget for this in order to make teaching and learning of physical science more effective. Edutrade can be contacted at 012 665 3933.

Plan ahead and don't run out of apparatus and chemicals!!
