# Selected Learning Outcomes for Primary 6 Science Papers (2014)

A test-tube of hot water was placed in a beaker of cold water as shown in a given diagram. It was observed that the temperature of the water in the test-tube decreased while the temperature of the water in the beaker increased after ten minutes.  Students are expected to be able to give a reason for this observation.

Bird Q spends a lot of time wading in cold water to look for food.  Bird Q is often seen standing on one leg and at times, it switches the leg that is in contact with the cold water.  Students are to give a reason for such a behavior.  Bird Q is also seen placing the other leg into its feathers.  Pupils are required to explain how this behavior reduces heat loss from the body.

A given diagram shows how blood is circulated to and from lung, heart and other parts of the body.  Path A flows from lung to heart and then to other parts of the body, while path B travels reverse way. 2 blood samples were taken at the same time from 2 different blood vessels in the body. The given graph shows the amount of oxygen present in the 2 blood samples P & Q. Students are supposed to match the blood samples P & Q to the path of blood flow A & B and explain the answer.

Jane wanted to find out how the amount of water in a fabric affects how well the fabric burns. She put different amount of water on 4 identical pieces of fabric A, B, C and D, each measuring 5 cm by 5 cm. She set fire to the 4 pieces of fabric in a closed room at the same time and took note of the time taken for each fabric to burn completely and recorded her results in a given table.  The table has 3 columns namely fabric type, number of drops of water added and time taken for the fabric to burn completely (seconds).  Students should be able to state the relationship between the amount of water put on each piece of fabric and the time taken for each fabric to burn completely.  They are to advise how carrying out the experiment in a closed room ensures that the experiment is a fair test.

Wildfires can easily occur when heat, oxygen and fuels are present. A given graph shows the amount of rainfall in Country X over a year.  Based on the graph, students are to determine with explanation which period Country X would most likely experience the most number of wildfires.

James poured 200 ml of water of the same temperature into each of the three plastic containers, X, Y and Z, as shown in a given diagram.  He measured the time taken for the water in each container to evaporate completely. A graph shows the results for the container X. Students are to draw and label the results for containers, Y and Z, in the same graph. They are to advise how the make the results of the experiment more reliable.
