Grade 4

Matter, substances and materials

Module 50

Matter

Activity:

To discover the properties and experience the wonder of matter

[lo 1.1.2, 2.2.1]

Let’s play the game:

I spy with my little eye…..

and then describe the thing that you see by answering the following:

How does it feel? (hard, soft, etc.)

Can one eat or drink it?

Can one play with it?

The one who guesses the answer correctly gets a point. If after five guesses your partners cannot guess what it is, you get a point.

What is matter?

Everything you can touch is matter .

Matter has mass

Try the following (1):

Pick up your ruler. What does it feel like?

Pick up your partner. How does that feel? Which one was more difficult to pick up?

My finding is that:

Matter occupies space

Try the following:

Take a glass of water.

Put flowers in the water. What happens to the water?

Why do you think it happened?

My finding is that:

From old newspapers cut out all the pictures on the first ten pages. The pictures should be of living and non-living matter. Make two piles of pictures, one for living matter and one for non-living matter. First list the properties of living matter before you begin cutting out.

Assessment

LEARNING OUTCOME 1: SCIENTIFIC INVESTIGATIONS

The learner will be able to act confidently on curiosity about natural phenomena, and to investigate relationships and solve problems in scientific, technological and environmental contexts.

Assessment Standard

We know this when the learner

  • plans investigations:

1.1.2 talks about personal experiences, highlighting aspects which relate to science or technology.

LEARNING OUTCOME 2: CONSTRUCTING SCIENCE KNOWLEDGE The learner will know and be able to interpret and apply scientific, technological and environmental knowledge.

Assessment Standard

We know this when the learner

categorises information: sorts objects and organisms by a visible property:

  • follows instructions to sort animals in groups of those with two legs, with four legs, and with more than four legs.

Memorandum

Try the following (1)

  • Pick up your ruler. What does it feel like? Pick up your partner. Which one was more difficult to pick up?
  • Answer:
  • The ruler is lighter than the partner but both have mass.

Try the following (2)

  • Take a vase containing water. Put in a bunch of flowers. What happens to the water? Why does this happen?
  • Answer:
  • The water rises in the vase. The flower and the water are both matter. Both occupy space.

PROPERTIES OF LIVING MATTER

List the properties that living matter must have before you begin cutting out.

  1. Movement: It must be able to move.
  2. Respiration: It must be able to breathe.
  3. Procreation: It must be able to breed.
  4. Ingest food: It must be able to consume food.
  5. Excretion: It must be able to excrete undesirable substances such as sweat.

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.

velocity can be 72 km/h in question. 72 km/h=20 m/s, v^2=2.a.x , 20^2=2.a.50, a=4 m/s^2.

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?
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).

specific heat capacity is the amount of energy needed to raise the temperature of a substance by one degree Celsius or kelvin
