What is a manipulated (independent) variable?
What is a responding (dependent) variable?
What are controls?
What is a hypothesis? AND… What format do you ALWAYS use when writing a hypothesis?
Read the following passage and answer the questions that follow.
Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that
coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the
shower with coconut juice. He sprays the other half of the shower with water. After 3 days of
"treatment" there is no change in the appearance of the green slime on either side of the shower.
What was Homer’s initial observation?
Identify the manipulated variable:
Identify the responding Variable:
Identify ALL controls:
What should Homer’s conclusion be? Explain WHY.
