Robinson did many things to take care of his safety. He made sure he had food, water and shelter. He could protect himself from wild animals. He could keep himself warm by making a fire. What could go wrong?
Try to think of something that could spoil life for Robinson.
What if he caught the flu? The full word is in-flu-en-za. It is caused by a virus, which gets into your body. Most of you have had flu or even a cold. What happens to your body when you have flu?
Discuss and list the symptoms.
The difficult thing about flu is that we cannot cure it. We just have to wait for the virus to go away. But doctors can give us medicine so that our heads and bodies won’t hurt so much. We also need to keep away from other people so that we don’t pass the virus onto them.
It is difficult to avoid catching a virus. A virus is too small to be seen so you can’t walk away if you see it coming. Some people have an injection to stop them getting the flu. The best way is to eat healthy food and build a strong body that can fight the germs by itself.
Draw a picture of a person that’s lying in bed with flu.
Technology
We have said that Robinson required food, water and shelter.
What kind of shelter would he be able to construct?
Find out about different types of houses. What do they all have?
Make a list of everything you need in a house and what it is made of.
Would Robinson be able to build a house like this? Remember he was on a deserted island.
Plan a kind of shelter for him. Sketch your design. Remember to say what each part would be made of.
Now make a model from your design.
Evaluate your design:
Does your model look like the design?
Where is it different?
Do you think Robinson would be able to build it?

2.1 describes key features of different places, including people's interactions with the places. (in this case, homes).
Memorandum
In the following task the learners return to Robinson. He is able to see to his primary needs
while he is in good health. Lead the discussion to how Robinson could cope if he became ill, because he is not eating healthily. A common cold would set him back if he is not able to do his normal tasks. How could it be avoided? Lead them to realize that there is a difference between flu (influenza) and a common cold. While they are compiling a list of symptoms, let them take notice of the following facts:
Flu affects the entire body so that the muscles and joints become painful. Even the heart may be affected by the virus. Vaccination is available, but it helps for only a year. It is not the same virus that attacks people year after year, with the result that a new vaccine must be developed every year. And then it does not cure the sick person – it only weakens the virus.
A cold usually affects only the upper part of the respiratory tract and does not always cause fever, as is the case with flu, but it may cause a sore throat, coughing and a running or blocked nose. As in the case with flu, the patient will get better only after the virus has left the body. The virus is transmitted from one person to another through the air.
Let them suggest ways to avoid catching flu or a cold. These should include the following: keeping your own body healthy, so that the immune system can fight off germs; stay away from people who have the virus; don’t share the same straw, cup, mug, glass, cold drink tin, fruit juice bottle, etc., with them.
After having discussed the symptoms and likely reasons for cold and flu, an additional activity could be attempted. Let the learners role play a visit to the doctor. Let the ‘patients’ complain about the symptoms that will be indicative of either cold or flu. The ‘doctor’ must then give some information about the cold or flu, e.g. “I can prescribe medication that will help for your headache, but it will not cure you.”
Remind the children of the importance of exercise in building a healthy body. Muscles need to stretch and move. One should not stay in a sitting position all day. Include a few lessons of movement: walking, jogging, skipping and running. Even dancing will make the muscles
move . Bring music into the lesson or ask the children to bring theirs and allow free ‘dance’ time at the end of the lesson.
In each session include a few exercises to help suppleness, touching toes (allow bent knees, especially at first) sitting cross legged, stretching bodies into different shapes. Always emphasize care of the back and only to do what your body
can do – don’t copy your neighbour and listen to your own body. If something is sore, STOP! End off with a game (or the dance time) and a cool down time.
Children can lie or sit with eyes closed in a completely relaxed position for the last few minutes. Choose a winner or allow them to stand and return to line or class one at a time. This also serves to restore discipline after an exciting lesson!
The children must plan to build a model shelter for Robinson. Help them to research houses in the area, visit a house that is in the process of being built (and don’t forget the necessary safety precautions!), and encourage them to look closely at their own houses and the material that has been used to build them. Take out some library books on houses of other cultures etc. Draw their attention to the fact that the house is
built according to the needs of the people : the most obvious being in response to climate, for example central heating in countries with a cold climate, etc.
Then ask the question, “What do we need in a house?” Let them fill in the list – roof, walls, windows, floors, fixed fittings, bathroom and toilet, etc., and what they are made of.
Remind them that Robinson had had limited resources. Let them first plan and design the shelter before they build it.
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.
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?
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.

A boat travels due east at a speed of 40meter per seconds across a river flowing due south at 30meter per seconds. what is the resultant speed of the boat
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
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
pratica A on solution of hydro chloric acid,B is a solution containing 0.5000 mole ofsodium chlorid per dm³,put A in the burret and titrate 20.00 or 25.00cm³ portion of B using melting orange as the indicator. record the deside of your burret tabulate the burret reading and calculate the average volume of acid used?
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.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?
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).
