Question

1. ladarius wants to find out if orange juice or orange soda melts faster than plain ice. he pours each of the liquids into empty ice cube trays of the same size and puts the trays in the freezer overnight. the next day, he pulls the ice tray out, puts each cube on its own white plate and watches them melt. when the last part of the frozen liquid melts, he records the time.

independent variable:
dependent variable:
control group:
experimental group:
constants:

Explanation:

• Independent Variable: The factor that is changed or manipulated. Here, it's the type of liquid (orange juice, orange soda, plain water).
• Dependent Variable: The factor that is measured. It's the time it takes for the ice - cube (formed from each liquid) to melt completely.
• Control Group: The group that is used for comparison and is not exposed to the experimental treatment. Plain ice (formed from water) is the control group as it is the baseline for comparison with orange - juice ice and orange - soda ice.
• Experimental Group: The groups that receive the experimental treatment. Orange - juice ice and orange - soda ice are the experimental groups.
• Constants: These are the factors that are kept the same throughout the experiment. The size of the ice - cube trays, the temperature of the freezer, the type of plate (white plate), and the initial volume of each liquid (since they are poured into trays of the same size) are constants.

Answer:

• Independent Variable: Type of liquid (orange juice, orange soda, water)
• Dependent Variable: Time taken for the ice - cube to melt
• Control Group: Plain ice (formed from water)
• Experimental Group: Orange - juice ice, Orange - soda ice
• Constants: Size of ice - cube trays, freezer temperature, type of plate, initial volume of each liquid
