Question

day 1: download or print the pdf for this lesson and follow along in the notice and wonder science experiment lab report as instructed. after completing todays tasks in the lab report, come back and answer the practice questions for day 1. what is the dependent variable in this science experiment? the type of salt is the dependent variable. the color of the food coloring is the dependent variable. there is not a control in this... the size of the crystals is the dependent variable.

Explanation:

In a science experiment, the dependent variable is what's measured/observed, dependent on the independent variable. Here, crystal size is likely measured as a result of other factors (like salt type, etc.), while salt type and food coloring color are independent or not relevant. The "control" option is about control group, not dependent variable.

Answer:

D. The size of the crystals is the dependent variable.
