WS01 - Bouncing ball

Science, Year 8

By the end of Year 8 students explain the role of specialised cell structures and organelles in cellular function and analyse the relationship between structure and function at organ and body system levels. They apply an understanding of the theory of plate tectonics to explain patterns of change in the geosphere. They explain how the properties of rocks relate to their formation and influence their use. They compare different forms of energy and represent transfer and transformation of energy in simple systems. They classify and represent different types of matter and distinguish between physical and chemical change. Students analyse how different factors influence development of and lead to changes in scientific knowledge. They analyse the key considerations that inform scientific responses and how these responses impact society. They analyse the importance of science communication in shaping viewpoints, policies and regulations. 

 

Students plan and conduct safe, reproducible investigations to test relationships and explore models. They describe potential ethical issues and intercultural considerations needed for specific field locations or use of secondary data. They select and use equipment to generate and record data with precision. They select and construct appropriate representations to organise and process data and information. They analyse data and information to describe patterns, trends and relationships and identify anomalies. They identify assumptions and sources of error in methods and analyse conclusions and claims with reference to conflicting evidence and unanswered questions. They construct evidence-based arguments to support conclusions and evaluate claims. They select and use language and text features appropriately for their purpose when communicating their ideas, findings and arguments to specific audiences.

Annotations

 

1. Identifies forms of energy and uses understanding of energy transformations to support a hypothesis. 

2. Describes the steps of the experimental method, identifying processes that ensure a reproducible investigation.

 

3. Identifies variables to be changed, measured and controlled.

4. Identifies some actions that will contribute to conducting a fair test.

 

5. Creates an appropriately labelled table to present measured data.

6. Constructs a line graph that follows graphing conventions and uses trendlines to clearly demonstrate a trend in the data.

 

7. Analyses patterns in data to justify the observed trend and identify the relationship between variables.

8. Explains observations with reference to energy transformations and transfers.

 

9. Compares results with predictions and interprets observed discrepancies, with reference to physical processes and measured data.

 

10. Identifies experimental challenges and sources of possible error, describing how they may have impacted on data accuracy.

 

11. Describes how the use of digital tools supports the precision of data. 

12. Suggests modifications to the experimental method that would improve data accuracy. 

13. Compares results obtained for different types of balls and uses scientific reasoning to analyse and explain the causes of observed differences.
