Students describe the images seen in flat and convex mirrors.

Students investigate energy transfer by colliding marbles, explaining their observations, and what happens to the energy of the moving marble on impact.

For this practical task students investigate convection currents when tea leaves are placed into a beaker of water that is being heated. They are asked to make observations and to provide an explanation of what they have observed.

For this practical task students are assessed on their ability to observe changes that have occurred to 'popping' corn before and after it is heated. Drawings and written observations are required.

This practical task requires students to make observations of the changes that occur in five common foods as they are cooked.

For this practical task students record their observations as an egg is poached in water.

Students are given some solids and liquids for this practical task. They plan how they would find out which liquids are solvents for any given solid, carry out the task, and write a conclusion.

Students complete a plant record for a tree by making observations.

Pictures are given of the life cycles of three different animals (hawk, turtle and deer). Students identify which stage the animal's survival is most in danger and give explanation of why it is not safe. Students also give one special feature that helps this animal survive at this time.

For this practical task students investigate water (and dye) movement in a plant when the stem of a daisy is cut lengthwise into three sections. Students record their observations and then explain their results in a scientific way. Key words have been provided.

For this practical task students are given a variety of objects which they are required to make observations on by using their senses.

This practical task is about heat absorption. From a given list students choose the equipment they would use to heat cold tap water as much as possible. Students complete the investigation, explain why each piece of equipment was selected, and record their results.

Task: Interpret data from tables. Assessment focus: data interpretation.

Task: Design a station on Mars. Assessment focus: problem solving to meet human needs in a different environment.

This practical task assesses students' ability to design and carry out a fair test on the relationship between slope and rates of erosion.

This task requires students to determine the best way to dissolve Milo the quickest. Students are given the opportunity to determine this by trial and error, then they are asked to write up their result and a conclusion.

For this practical task students determine the viscosity of different household susbstances such as golden syrup, cooking oil, fruit juice etc. Students complete the experiment and construct a chart showing their results and observations.

Task: Name the parts of a bike and describe how some of them work. Assessment focus; knowledge of the working systems of a bicycle.

For this practical task students make observations about the effect of coloured lights on different coloured objects. Students then draw some conclusions about their findings.

In this practical students are first required to identify as many uses of paper they can think of. Then, using samples of different paper types, they identify particular uses for that type of paper and reasons why the paper is used for this purpose.

Students use a table on solubility/insolubility of 16 compounds to determine the validity of four statements and justify with evidence from the table.

Students explain their understandings of the benefits of having trees in the school playground.

Task: Complete a drawing of things found in and near a flax bush, and describe relationships between them. Assessment focus: interdependence in a flax bush environment.

Task: Students identify which different events threaten our native birds or have done so in the past. Assessment focus: identification of the specific impacts of human actions.

Students make inferences from visual cues and make links between visual and written text. SJ-2-3-1997.
