## How to determine direction

ACTIVITY 1:

TO DETERMINE NORTH BY USING A WRISTWATCH

[LO 1.7]

You need the following :

a watch with hands

a match or stick

Step 1 : Stand outside on a sunny day. Hold your watch horizontally (flat) on your hand.

Step 2 : Hold the stick above the 12 on the watch.

Step 3 : Move around until the shadow of the stick falls on the 6 to 12 line.

Step 4 : Halve the angle between the hour hand and the 6 to 12 shadow line. The halve line is North .

ACTIVITY 2:

TO DETERMINE NORTH BY USING A SHADOW STICK

[LO 1.7]

Divide the class into groups. Choose a sunny day. This method requires a few hours, because the sun has to rise to its highest point and then go down again.

You need the following :

a ruler

a pencil

a large piece of white paper

a knitting-needle or straight stick

Step 1 : Put the paper on level ground and push the knitting-needle through its centre.

Step 2 : At 10:00, indicate the point of the shadow on the paper.

Step 3 : At 14:00, indicate the point of the shadow on the paper.

Step 4 : Now remove the paper and return to the classroom. Draw lines from the shadow point you have marked, to the point where the needle was. (See Figure 5.)

Step 5 : Halve the angle formed by ABC. The line on the opposite side of the shadow will be TRUE NORTH.

ACTIVITY 3:

TO DETERMINE DIRECTION AT NIGHT WITHOUT A COMPASS

[LO 1.7]

Do some research to find out how you would orientate yourself at night without a compass (in other words, how you would determine true north at night).

Make drawings and write down your information, so you can report your findings to the class.

In the library, find at least two sources with information about your subject.

Read the first source and write down the information under SOURCE 1.

Then read the next source and write down the information that wasn’t given in the first source, under SOURCE 2.

Use the information from both sources to write a paragraph or two.

## Assessment

LO 1

GEOGRAPHICAL ENQUIRY

The learner will be able to use enquiry skills to investigate geographical and environmental concepts and processes.

We know this when the learner:

• with guidance, selects and uses sources of useful geographical information (including graphs, maps and fieldwork outside the classroom) [finds sources];
• categorises information [works with sources];
• draws sketch maps and/or plans from field observation and measurements [works with sources];
• uses an index to find places on global atlas maps [works with sources];
• demonstrates knowledge and understanding of the issue through projects, discussion, debate and charts [communicates the answer].

anyone know any internet site where one can find nanotechnology papers?

Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes

Do somebody tell me a best nano engineering book for beginners?
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
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.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
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.
Harper
Do you know which machine is used to that process?

how to fabricate graphene ink ?
for screen printed electrodes ?
