Here is your challenge first identify the specific questions...

Here is your challenge: • First, identify the specific question(s) the authors are asking. • Second, what is the hypothesis that they suggest? • Third, what predictions (deductions) can you make if the hypothesis is correct? • Fourth, how can we test the predictions, i.e., what exactly might we do if we were the authors who had studied coots for several years?

Transcript

00:03 The experiment were described, you have in three groups, two groups of control and one group that has half -trimmed of chicks and the other half -trimmed with their feather.

00:19 So the question says that the biologists worry about what kind of data to collect, how to collect the data and what kind of result to expect.

00:32 So in this experiment, the biologists need to focus on collecting data that can assess the effect of feather trimming.

00:53 The hypothesis for this project most likely is feather trimming could affect the chips behavior, social interaction, or development.

02:03 So second, what kind of data should you collect? the data that need to be collected to measure will be for something like, for example, chick's survival rate.

02:25 Because in the beginning of the question, it says it talks about the set up the three type of nesting conditions.

02:34 So these chicks, they're still very young, and then the fetter treatment might affect their survival to adulthood.

03:13 And the second set of data that you should collect will be something like behavioral observation, such as activity level, feeding behavior.

03:53 So for example, how often they approach food source, how much they feed, and social behavior.

04:06 Means that how they interact with siblings.

04:11 And also, other data that could be meaningful will be the growth in development.

04:23 Again, these are very young chicks.

04:26 Tripping feather might affect their growth rate, such as weighing gain over a period of time.

04:52 So this would actually show if feather trimming and color change have any long -term effect on growth or health.

05:01 So the third question asked about how you collect this data.

05:08 So, first of all, you want to make sure that all these behavioral data will be standardized, i will say.

05:36 So all behavioral observation should be done at the same time after chicks are returned to their nest.

05:42 So this ensure consistency and comparability across the group.

06:28 And second, you can actually video recording to analyze the behavior...
