Gravity and Electromagnetism (Gravity and motion) Assignment

Assignment Task

Context

You have completed the following practical in class:

• Conduct an experiment to determine the horizontal distance travelled by an object projected at various angles from the horizontal.

Task

You are to modify (i.e. refine, extend or redirect) the experiment outlined in the context in order to address your own hypothesis or question related to the practical.

To complete the task, you must:

• Identify an experiment to modify
• Develop a research question to be investigated
• Research relevant background scientific information to inform the modification of the research question and methodology
• Conduct a risk assessment and account for risks in the methodology
• Conduct the experiment
• Collect sufficient and relevant qualitative data and/or quantitative data to address the research question
• Process and present the data appropriately
• Analyse the evidence to identify trends, patterns or relationships
• Analyse the evidence to identify uncertainties in the data and trendlines and appropriate limitations of the data. 
• Interpret the evidence to draw conclusion/s to the research question 
• Evaluate the reliability and validity of the experimental process
• Suggest possible improvements and extensions to the experiment 
• Ommunicate findings in an appropriate scientific genre

Research question

What is the relationship between the speed of sound in air and the temperature of the air when measured in a 2 m long, 10 cm diameter PVC pipe using a 1500 Hz sound source?

Description

• Identify the independent variable to be investigated.
• Identify the dependent variable.
• Identify the methodology to be used.
• What is the relationship between the speed of sound in air and the air temperature?
• What is the relationship between the speed of the sound in air and the temperature of the air when measured in a 2 m long, 10 cm diameter PVC pipe using a 1500 Hz source?
