Life orientation

Grade 5

Health and diseases

Module 4

Contributing towards a healthier environment

Activity:

To contribute towards a healthier environment

[lo 1.2]

It would be ideal if the class group could start an environmental project in the area through which they could make a positive contribution. You could all go on a cleaning-up excursion in and around the local river on a Saturday. Make sure that safety precautions are taken, e.g. gloves must be worn and no one should go into the river without shoes. Ask your parents to be involved in the project.

Assessment

LO 1

HEAlTH PROMOTION

The learner will be able to make informed decisions regarding personal, community and environmental health.

We know this when the learner:

1.1 explores and reports on ways to protect the quality of food and water in various contexts;

1.2 investigates a local environmental health problem using different data sources, and plans a strategy to address the problem;

1.3 recognises the symptoms and causes of locally occurring diseases and discusses prevention strategies;

1.4 explains the individual health and social effects of substance abuse.

Memorandum

Life Orientation for Grade 5 consists of a number of modules focussing on:

  1. Health and diseases
  2. Social development: rights and responsibilities
  3. Personal development

4. Physical development and movement

The first modules, 1-7, prepare the learners to be responsible consumers and to make sound, informed choices regarding their own diets. They are also made increasingly aware of health risks in their own environment and of their responsibilities regarding the maintenance of balanced ecosystems. While there was merely a brief reference to certain children’s rights in Grade 4, the Grade 5 learners are now given the opportunity to focus on their rights and duties as citizens of the country. The sensitive issue of child abuse is also broached. Educators must realise that they have a great responsibility as consultants, confidants and counsellors in this regard. It is here that serious problems can be identified and prevented. It is essential that educators should know the correct procedure should they have to deal with a case of child abuse. During discussions on contagious diseases educators are also in a position to play an important role in preventing life-threatening diseases such as TB, cholera and aids by approaching these topics with the necessary seriousness.

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
definitely of physics

how do lnternal energy measures

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?

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).
