Penguin Growth Experiment Analysis

The video tutorial guides students through activity 11, focusing on an experiment testing the effect of a special feed on penguin growth. It explains the setup, including control and test groups, and provides instructions on graphing and analyzing the data. The importance of using twin penguins to eliminate genetic variables is discussed. Students are encouraged to complete further activities and are reminded to work at their own pace.

What is the main purpose of the experimental setup involving BC and Bertha?

• To study the habitat preferences of penguins

• To measure the intelligence of penguins

• To observe the behavior of twin penguins

• To test the effect of different feeds on penguin growth

Which penguin is part of the control group in the experiment?

• BC

• Bertha

• Both BC and Bertha

• Neither BC nor Bertha

Why is it important to graph the data collected from the experiment?

• To make the data look more appealing

• To easily compare the weight gain over time

• To hide the actual results

• To confuse the students

What should be labeled on the y-axis of the graph?

• Time in months

• Weight in pounds

• Type of feed

• Penguin names

Which month did both penguins weigh the same?

• April

• May

• August

• June

What conclusion can be drawn from the experiment regarding the feed?

• Neither feed affects weight gain

• The regular feed leads to faster weight gain

• The experimental feed is more effective

• Both feeds are equally effective

Why were twin penguins used in the experiment?

• To confuse the observers

• To save on feed costs

• To make the experiment more interesting

• To ensure they have similar genetic material

What is a confounding variable in the context of this experiment?

• A variable that is intentionally changed

• A variable that is kept constant

• A variable that could affect the results unintentionally

• A variable that is irrelevant to the study

What is the significance of removing genetic variables in the experiment?

• To ensure the results are due to the feed

• To make the experiment more complex

• To increase the number of variables

• To reduce the cost of the experiment

What activities are students required to complete after the video?

• Activities 6 to 10

• Activities 12 to 15

• Activities 16 to 20

• Activities 1 to 5
