WS01 - Big bang theory

Science, Year 10

By the end of Year 10 students explain the processes that underpin heredity and genetic diversity and describe the evidence supporting the theory of evolution by natural selection. They sequence key events in the origin and evolution of the universe and describe the supporting evidence for the big bang theory. They describe trends in patterns of global climate change and identify causal factors. They explain how Newton’s laws describe motion and apply them to predict motion of objects in a system. They explain patterns and trends in the periodic table and predict the products of reactions and the effect of changing reactant and reaction conditions. Students analyse the importance of publication and peer review in the development of scientific knowledge and analyse the relationship between science, technologies and engineering. They analyse the key factors that influence interactions between science and society. 

 

Students plan and conduct safe, valid and reproducible investigations to test relationships or develop explanatory models. They explain how they have addressed any ethical and intercultural considerations when generating or using primary and secondary data. They select equipment and use it efficiently to generate and record appropriate sample sizes and replicable data with precision. They select and construct effective representations to organise, process and summarise data and information. They analyse and connect a variety of data and information to identify and explain patterns, trends, relationships and anomalies. They evaluate the validity and reproducibility of methods, and the validity of conclusions and claims. They construct logical arguments based on analysis of a variety of evidence to support conclusions and evaluate claims. They select and use content, language and text features effectively to achieve their purpose when communicating their ideas, findings and arguments to diverse audiences.

Annotations

 

1. Clarifies that big bang theory explains the evolution of the universe rather than its origin. 

 

2. Summarises key events of the evolution of the universe according to big bang theory, making references to time, size and condition of each stage.

 

3. Identifies steady state theory as the main opposing theory of the universe and gives historical context for the scientific debate that ensued.

 

4. Explains the meaning of red shift and constructs a logical argument based on analysis of evidence as to how red shift provides evidence in support of big bang theory.  

5. Explains the meaning of cosmic microwave background radiation (CMBR). 

 

6. Names scientists who predicted the existence of CMBR from theory as well as scientists who provided experimental evidence for it.

 

7. States that the discovery of CMBR has provided convincing evidence for big bang theory and against steady state theory.

 

8. Evaluates quality and amount of evidence and draws conclusion in favour of big bang theory.

 

9. Provides a list of references from trustworthy sources.
