Trees

Trees

  • Trees form a very important part of our environment. We even have a day to remember their special role, Arbour Day. Most organisations try to plant a tree or a number of trees to mark this occasion. Why do we have a special day to remember trees?
  • Trees have many uses for mankind. Look at the diagram and discuss the many ways in which we use trees.

  • Not only are they useful but they also improve the beauty of our world.

From wood to paper

  • The products made from trees are usually made from wood. In your groups read about the process of how we use wood to make the very paper you write on.

1. When the trees have grown to a certain size,

they are marked to make sure that they are not all sawed off at the same time.

2. The trees are cut and taken to the sawmill.

3. Here they are stripped of their bark and cut into planks or smaller sizes.

4. The wood for paper is chopped and mashed until it is pulp.

5. It is dried and rolled into huge rolls of paper.

  • Hundreds of trees go into the making of paper. Every time a tree is cut to be made into paper, another tree must be planted, but it will take seven years for that tree to grow big enough. Trees are a precious resource and we must look after them.
  • Now answer these questions in your groups.

1. Why should we look after trees?

How can we look after trees?

  • Make drawings of what you can do to take care of your trees.
  • We have said that we get wood from trees, but wood is not only used to make paper. Wood has many uses. In the past it was essential just to keep warm, many houses were built of wood and most furniture was made of it Nowadays we use other materials to make furniture.
  • What materials are these? Find out and list them.
  • Do you think they are better?

Investigate a chair

  • What do we want when we sit in a chair?
  • It must be comfortable.
  • It must not break.
  • What else is important?

Try out the chairs in your home.

  • What are they made of?
  • What are their good points?
  • What are their weak points?
  • Fill in your findings in the table below.

Memorandum

Observe the trees all around us. Look at the different size and shapes, look at the texture of the bark and leaves. Allow the children to discover and create patterns with the leaves or textures they observe in the trees (A&C 1.8; 1.9).

Enact the tree growing from seed. Encourage the children to move slowly to show how the tree pushes out each tiny shoot or root. Then try to emulate movements in the wind.

Contrast the movements made by nature with a noisy timber factory, as the children become the machinery that will chop and cut and saw the wood as they

will read on the page about a timber factory (‘From wood to paper’).

(expressing and communicating: a&C 4.4).

First explain to the learners what the difference between a plantation and a forest is, and then let them draw a picture of a plantation on the cover page of the module.

Valentine’s Day is a good example of this. The business world just cashed in on people’s unlimited wants. Naturally these will continue to change. End the questionnaire by asking what they think their children might want (EMS LO 1.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

how do lnternal energy measures
Esrael
Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?
Robert
like charges repel while unlike charges atttact

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
