The Mystery of Galaxy ZScenario: An astronomer is studying a distant galaxy (Galaxy Z) and records the following data: Observation 1: The light spectrum shows a massive “Red Shift.”Observation 2: The galaxy contains many “Main Sequence” stars that are much larger and bluer than our Sun. Question: Based on these observations, describe the speed and direction Galaxy Z is moving relative to Earth. Then, describe the future of the blue stars—what will they eventually turn into, and why do they have shorter lives than stars like our Sun? (4 Marks)

According to Hubbles law what is the relationship between a galaxy’s distance from Earth and the speed at which it is moving away? (We saw this in the video explaining the expanding universe, think about the slinky!)

Scenario: A scientist uses a spectroscope to look at two stars. Star X shows a spectrum where the lines have shifted toward the blue end. Star Y shows lines shifted toward the red end.Question: Compare the movement of these two stars relative to Earth. Which one is moving toward us, and how do you know? (2 Marks)

Scenario: You are comparing a Red Dwarf star and a Blue Supergiant star.Question: Predict which star will have a longer total lifespan and explain why based on how they consume their fuel. (2 Marks)

Scenario: A student wants to see if the color of a container affects how much heat it absorbs from a lamp. They use a black can and a silver can, but the black can is filled with 100ml of water while the silver can is filled with 500ml.Question: Explain why this experimental design is flawed and identify what the student should change to make it a “fair test.” (2 Marks)
