An overview of practical work

Educators now have clarity regarding the role and assessment of practical work. This document specifies that practical work must be integrated with theory to strengthen the concepts being taught. Practical work can be: simple practical demonstrations; an experiment or practical investigation. In Section 3 practical activities are outlined alongside the content, concepts and skills column. The table below lists prescribed practical activities for formal assessment as well as recommended practical activities for informal assessment in Grade 10.

Term Prescribed Practical Activities for Formal Assessment Recommended Practical Activities for Informal Assessment
Term 1 Experiment 1 (Chemistry) :Heating and cooling curve of water. Practical Demonstration (Physics): Use a ripple tank to demonstrate constructive and destructive interference of two pulses or
Experiment (Chemistry): Flame tests to identify some metal cations and metals.
Term 2 Experiment 2 (Physics): Electric circuits with resistors in series and parallel – measuring potential difference and current. Investigation (Physics): Pattern and direction of the magneticfield around a bar magnet or
Experiment (Chemistry): Prove the conservation of matter experimentally.
Term 3 Project: Chemistry: Purification and quality of water. or Physics: Acceleration. Experiment (Physics): Roll a trolley down an inclined plane with a ticker tape attached to it, and use the data to plot a position vs. time graph or
Experiment (Chemistry):
Reaction types: precipitation, gas forming, acid-base and redox reactions.
Term 4 Experiment (Chemistry): Test water samples for carbonates, chlorides, nitrates, nitrites, pH, and look at water samples under the microscope.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
