Why can I see the moon during the day?

Science Grade 9:

Mr. Zajac wants to conduct an experiment to see if Red Bull energy drink makes plants grow faster. He takes plant #1 and puts it on a ledge that gets lots of sunshine. He waters this plant with 100 mL of water everyday. He takes plant #2, puts it on the ledge beside plant #1, and pours 100 mL of Red Bull on it twice a day, once when he wakes up, and once before he goes to bed. (3 marks)

a. Is this a fair test? Explain why or why not. (2 marks)

b. What would you recommend to Mr. Zajac to fix his experiment?

Grade 9 Science experiment:

Experiment:  Compare brands of paper towels, to see which holds the most liquid. The independent variable in your experiment would be the brand of paper towel. The dependent variable would be the amount of liquid absorbed by the paper towel.

Come up with a problem, explain how you are going to control the experiment using a dependent variable, and use appropriate formats for displaying the observed and recorded data.
