A teacher gives extra credit to students who turn in homework on time. Over time, more students submit homework punctually. This is an example of:

Scenario: A student is testing if the mass of a toy rocket affects how high it flies. They use three rockets of different weights but use a different type of engine for each rocket to “make sure they all have enough power.” Question: Explain why this experimental design is flawed and identify what the student should change to make it a “fair test.” (2 Marks)

In the visible light spectrum, which color has the shortest wavelength and the highest energy?

A massive cloud of gas and dust where stars are born is called a:

Our Sun is currently in which stage of its life cycle?  

Scenario: You discover two different Nebulae. Nebula X contains enough gas to form a star the size of our Sun. Nebula Y contains ten times that amount of gas and dust. Question: Predict which nebula will likely result in a Black Hole at the end of its life cycle and explain why. (2 Marks)

Solve the equation (x^2 + 1)y′ + xy = x.

Solve the equation x^2y′ = 1 − x^2 + y^2 − x^2y^2,     y(1) = 0.You may leave your answer as an implicit solution.
