Question

Ms. Snodgrass wanted to find out if the amount of sugar in hummingbird food affected the number of birds visiting her feeder. In her experiment she ued three of the same feeders and the same amount of water, but used three different amounts of sugar: the amount of recipe, half recipe, and twice the recipe amount. What was the variable that Ms. Snodgrass observed was affected in this experiment? (what result was measured)

Answer 1

The variable Ms. Snodgrass observed in her experiment was the number of birds visiting her feeder, which is the dependent variable. She was investigating whether different sugar concentrations in hummingbird food (the independent variable) would affect the attraction of the hummingbirds.

Step-by-step explanation:

In Ms. Snodgrass's experiment, the variable that she observed to be affected was the number of birds visiting her hummingbird feeder. This is considered the dependent variable, as it is the outcome that is being measured and is expected to change in response to the varying amounts of sugar in the water, which is the independent variable. The independent variable is the factor that Ms. Snodgrass deliberately changed in her experiment, with the objective of finding out if different sugar concentrations would have an effect on the frequency of hummingbird visits to the feeders.

By conducting this experiment with three different sugar concentrations – the recommended recipe amount, half the recipe amount, and twice the recipe amount – she was looking to see if the amount of sugar in the hummingbird food would increase or decrease the attraction of the hummingbirds to the feeders.
