Science Assessment Map – Sample at 4.25
Heating water
Context
Students were asked to perform an experimental investigation to find out how long it took ice to melt and the water to start to bubble and boil. The students worked in small groups to complete the experiment and completed the worksheet independently (using the data from their experiment) for homework. The experiment took 45 minutes of class time to complete.
The elements of the Science at work Level 5 standard addressed by the task are:
(Students) demonstrate safe, technical uses of a range of instruments …
(Students) make systematic observations and interpret recorded data appropriately …
(Students) use appropriate diagrams … when reporting on their investigations.
Samples
The following work samples, and the related Science 4.25 progression point examples, illustrate the kinds of responses that students produce as they progress towards the Level 5 standard.

Annotation
Science at work – 4.25
- Shows data results graphically although temperature label and units are not included in vertical scale, and time scale is too long.
- Does not show a table of results.
- Draws diagram accurately and labels it correctly.
- Includes related safety requirements (risk assessment) but does not discuss their impact (if any) on the outcome of the experiment.
- Includes in the aim of the task a reference to the time taken for ice to melt and the water to boil.
- Does not use the data collected to justify the conclusion drawn which is also incomplete.

Annotation
Science at work – 4.25
- Does not show a table of results.
- Records data appropriately (graphically) but stops at 80°C.
- Does not show a title on the graph, and there are no units on the temperature scale.
- Draws diagram accurately and correctly labels it.
- Explains clearly the related safety requirement.
- Includes in the aim of the task, a reference to ice melting.
- Makes a link to the data (states bubbles appeared as it got closer to 80°C) in the conclusion.
- Does not explain why measurements were not taken beyond 80°C.
- Conclusion does not directly relate to the aim.
