Activity: to ask simple questions and identify relevant data [lo 5.1]

To collect data and answer questions [lo 5.2]

To organise and record data [lo 5.4]

To investigate data to describe the main tendency [lo 5.5]

To draw graphs [lo 5.6.1/2]

To read and interpret data critically [lo 5.7.2]

** This task is for your portfolio.

Do it as neatly as you can, but first take note of how it will be assessed.

1. Let us look at your classmates' habits when it comes to eating breakfast. Find out what the other learners in your class have for breakfast.

2. Use the block below as a record sheet for recording your information:

Example:

GRADE 6
BREAKFAST NO. OF LEARNERS
Warm porridge 2
Bread 1
Rusks 6
Cereals 3
Fruit 8

3. You have already got to know a variety of graphs. (Do you remember any?) See whether you are able to record the information from the record sheet in a graph.

Breakfast

4. Find out WHICH breakfast food is the most popular among your class mates.

ASSESSMENT: BREAKFAST DATA

CRITERIA 1 2 3 4
Neatness and organisation The work is untidy and incomplete. The work is organised, but is difficult to read. The work is neat and organised and reads easily. Neat, clearly set out work; easy to read.
Graph The learner has not made any effort. Most of the information is indicated incorrectly. One or two mistakes occur. The graph is correct and neat.
Degree of completeness No research was undertaken.Some questions remain unanswered. Much of the required information is missing. Only very few questions remain unanswered. The task is completed fully.
Correctness of calculations All the answers are calculated incorrectly. Many mistakes occur. Few mistakes were made. All the answers are correctly calculated.

Assessment

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 5.1: We know this when the learner poses simple questions about own school and family environment, and identifies appropriate data sources in order to address human rights, social, political, cultural, environmental and economic issues in that environment;

Assessment Standard 5.2: We know this when the learner uses simple data collection sheets (requiring tallies) and simple questionnaires (with yes/no type responses) in order to collect data (alone and/or as a member of a group or team) to answer questions posed by the teacher, class and self;

Assessment Standard 5.4: We know this when the learner organises and records data using tallies and tables;

Assessment Standard 5.5: We know this when the learner examines ungrouped numerical data to determine the most frequently occurring score (mode) and the midpoint (median) of the data set in order to describe central tendencies;

Assessment Standard 5.6: We know this when the learner draws a variety of graphs by hand/technology to display and interpret data (grouped and ungrouped):

5.6.1: pictographs with a many-one correspondence and appropriate keys;

5.6.2: bar graphs and double bar graphs;

Assessment Standard 5.7: We know this when the learner critically reads and interprets data presented in a variety of ways (including own representations, representations in the media – words, graphs, pie graphs) to draw conclusions and make predictions sensitive to the role of:

5.7.2: categories within the data (e.g. age, gender, race).

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
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.
Tarell
what is the actual application of fullerenes nowadays?
Damian
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.
Virgil
is Bucky paper clear?
CYNTHIA
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?

Stotaw
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
Azam
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
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
