Javier loves to do his homework while listening to music. He believes that he does his homework with more correct answers when he listens to music. His parents believe that listening to music is distracting and causes more incorrect answers. For the first 10 days, Javier and his classmates complete their homework while listening to music. For the next 10 days, Javier and his classmates complete their homework without listening to music. Every day, their teacher records how many correct answers each student has.
IDENTIFY TWO FACTORS THAT MUST BE HELD CONSTANT:
Type of music, type of homework, amount of homework, amount of time given to complete homework, amount of classmates

Describe the method of formation for each of the three types of rocks:
Igneous
Sedimentary
Metamorphic
Igneous - Molten Rock cools and hardens
Sedimentary - sediments get deposited and buried, and compacted and cemented.
Metamorphic Rock - When any other type of rock goes under heat and pressure.

Explain the difference between reflection and refraction.
Reflection - The way in which a wave bounces off of a surface.
Refraction - The change in direction of a wave as it goes from one medium to another.

His parents believe that listening to music is distracting and causes more incorrect answers. For the first 10 days, Javier and his classmates complete their homework while listening to music. For the next 10 days, Javier and his classmates complete their homework without listening to music. Every day, their teacher records how many correct answers each student has.
What is the Hypothesis in this experiment?
If he listens to music while he does his homework, then he will get more correct answers.
