Planning to build a house

Activity:

To think about how to build a house

[lo 1.1.1, 1.2.2, 3.2]

To build a house

Let’s tell the story of the three pigs. Draw the story in the form of a comic strip. How many learners are there in your class? Draw the same number of blocks on a big sheet of cardboard. Measure the size of these blocks and give each learner an A4 sheet with a block of the same size to draw one of the comic panels. This project will take careful planning.

What do we call someone who designs houses and office buildings?

The straw and the sticks of the first two pigs did not work very well but the brick house of the third pig did. What conclusion can we draw from this?

Let’s be creative

Work together in groups of three. Decide what kind of house you want to design, draw and build. Decide if it will be a formal or an informal structure. Use any kind of waste material. If you want to carry the experiment further then you could put the house outside for a week, or have a fan blow onto it for a day. See which structure lasts the longest in all weather conditions.

1. Draw the house from above as in the drawing below. Use A4 paper.

2. Write down which rooms you will have in your house.

3. Design the furniture you will have in your house. Use the pictures as an example. Work in groups. Each group chooses a room and makes the furniture for that room from matchboxes or similar small boxes.

4. Write down the kinds of houses that the learners in your class live in. Have each learner colour in the house that he or she lives in. Now you can see which type of house most members of the class live in, for example, house, town house, flat, etc.

Assessment

LEARNING OUTCOME 1: SCIENTIFIC INVESTIGATIONSThe 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:

  • suggests actions to try with the materials;
  • conducts investigations and collects data:
  • tries own idea of how the materials might respond.

LEARNING OUTCOME 3: SCIENCE, SOCIETY AND THE ENVIRONMENT The learner will be able to demonstrate an understanding of the interrelationships between science and technology, society and the environment.

Assessment standard

We know this when the learner

  • understands the impact of science and technology: identifies features of technological devices around him or her, and tells about their purpose and usefulness:

Memorandum

To build houses:

  • What do we call someone who designs houses, buildings and offices?Answer:
  • Architect
  1. Use A4 paper to design a house. re are computer programmes that could help with this. If the school has the facilities please let the learners use them.
  2. They decide themselves which rooms are important and which not. If they have left out something e.g. the toilet, provide advice.
  3. Hold an exhibition of all the furniture that they have made.

4. Follow the instructions.

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
