Developing language skills: reading and writing

As a Physical Sciences educator you need to engage in the teaching of language. This is particularly important for learners for whom the Language of Learning and Teaching (LoLT) is not their home language. It is important to provide learners with opportunities to develop and improve their language skills in the context of learning Physical Sciences. It will therefore be critical to afford learners opportunities to read scientific texts, to write reports, paragraphs and short essays as part of the assessment, especially (but not only) in the informal assessments for learning.

Six main knowledge areas inform the Physical Sciences. These are:

  • Matter and Materials
  • Chemical Systems
  • Chemical Change
  • Mechanics
  • Waves, Sound and Light
  • Electricity and Magnetism

Time allocation of the physical sciences in the curriculum

The teaching time for Physical Sciences is 4 hours per week, with 40 weeks in total per grade. The time allocated for the teaching of content, concepts and skills includes the practical work. These are an integral part of the teaching and learning process.

Grade No. of Weeks Allocated Content, Concepts&Skills (Weeks) Formal Assessment
10 40 30 10
11 40 30 10
12 40 28 12

Topics and content to be dealt with in grade 10

(Consult the National Curriculum and Assessment Policy Statement for Physical Sciences for an overview of Grades 10 - 12)

Topic Content
Mechanics Introduction to vectors&scalars; motion in one dimension (reference frame, position, displacement and distance, average speed, average velocity, acceleration, instantaneous velocity, instantaneous speed, description of motion in words, diagrams, graphs and equations).Energy (gravitational potential energy, kinetic energy, mechanical energy, conservation of mechanical energy (in the absence of dissipative forces).
  • 30 hours
Waves, Sound&Light Transverse pulses on a string or spring (pulse, amplitude superposition of pulses); transverse waves (wavelength, frequency, amplitude, period, wave speed, longitudinal waves (on a spring, wavelength, frequency, amplitude, period, wave speed, sound waves); sound (pitch, loudness, quality (tone),ultrasound); electromagnetic radiation (dual (particle/wave); nature of electromagnetic (EM) radiation, nature of EM radiation, EM spectrum, nature of EM as particle – energy of a photon related to frequency and wavelength).
  • 16 hours

there is no specific books for beginners but there is book called principle of nanotechnology
what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
