Question

1. write a hypothesis for the following experiment. your hypothesis should be an if-then statement but does not need to have a \because\.

irina is running an experiment to test the effect of sugar on hummingbird activity. she gives hummingbird group a an extra concentrated sugar solution, and hummingbird group b a normal sugar solution, then measures activity over the next two hours.

Explanation:

The experiment is about the effect of sugar concentration (independent variable) on hummingbird activity (dependent variable). A hypothesis in IF - THEN form should relate the independent and dependent variables. So, we structure it as: If hummingbirds are given an extra concentrated sugar solution (group A) and a normal sugar solution (group B), then hummingbirds in group A will have a different (e.g., higher) level of activity compared to group B over the next two hours. (A more specific hypothesis could be: If hummingbirds are given an extra concentrated sugar solution, then their activity level will be higher than that of hummingbirds given a normal sugar solution over the next two hours.)

Answer:

If hummingbirds are given an extra concentrated sugar solution (group A) and a normal sugar solution (group B), then hummingbirds in group A will have a higher activity level than those in group B over the next two hours.
