Meet bonny and tommy

Educator section


The educator must help the learners to obtain the information on their birthdays in class so that they can complete the bar graph.

Let the learners raise their hands to show in which month their birthdays are. Count how many learners have birthdays in that month. The learners write this information in the circle above each month.

for example: three children have their birthdays in January. The 3 is written in the circle above Jan.

This can be a class activity.

It is also a good opportunity to learn the names of the months in the correct sequence. It is not required of them to write the names of the months at this stage.

Give the learners enough time to discuss their findings, make deductions and draw conclusions after they have completed the bar graph.

Leaner section


Activity: to complete a bar graph [lo 5.4, lo 5.5]

Bonny and Tommy are 8 years old and their birthday is on 13 May.

Then they will be ________________________________ years old.

  • They want to know when your birthdays are. Do you know when your birthday is?
  • Now you must help me! (Do you know the names of the months?)
  • Put up your hand if I mention the name of the month in which your birthday falls. I will count how many friends have a birthday in each month.
  • Write this number in the circle above the name of the month.
Jan. Feb. March Apr. May June July Aug. Sept. Oct. Nov. Dec.
  • Now we can complete the birthday graph.

Make an X to represent each friend in the month in which his or her birthday falls.

1. In which month(s) do most of the friends have their birthdays?


2. In which month(s) do the fewest of the friends have their birthdays?


3. What in the graph can change?


4. Why can it change?


5. What cannot change?


Draw a birthday cake with candles on. I want to see how old you are.

LO 5.4 LO 5.5


Learning Outcome 5: The learner will be able to collect, summarise, display and critically analyse data in order to draw conclusions and make predictions, and to interpret and determine chance variation.

Assessment Standard 5.4: We know this when the learner reads, interprets and reports on information in own and a peer’s representations of data;

Assessment Standard 5.5: We know this when the learner reads and interprets data presented in simple tables and lists.

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.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
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
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
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.
