4. Which metric measure would be best to use when measuring the amount of water given to a plant?

• milliliters
• meters
• kilograms
• centimeters

6. A student wishes to test the hypothesis that adding antifreeze to water lowers the freezing point of water. What would be the dependent (responding) variable?

• Amount of antifreeze added to the water
• Temperature at which water/antifreeze mixture freezes
• Type of thermometer used to measure the freezing point
• Amount of water put into a container

7. A student wanted to test the hypothesis that adding antifreeze to water lowers the freezing point of water. The student found that pure water froze at 0°C, while the water/antifreeze mixture froze at -20°C. In order to confirm the results, the student should repeat the experiment using -

• a different amount of antifreeze
• a different amount of water
• exactly the same set-up as the first experiment
• a container of a different size
