Teachers Questions and Answers
During the early 1900s, scientists performed an experiment which identified the
existence of a substance other than DNA was involved in protein synthesis. Since they

A teacher wishes to introduce the topic of climate change to a class. The teacher knows
this is a controversial topic as some of the students in the class do not believe that
climate change is occurring or that human activity contributes to the phenomenon.
Which of the following actions describes a method for students to evaluate the scientific
evidence relating to climate change?
Facilitate a discussion asking students to outline their prior knowledge about climate
change and the contributing factors.
Allow students to watch a fictional disaster movie in which the plot revolves around the
negative effects of climate change, then facilitate a discussion about how climate
change caused the disasters in the movie.
, Lead a lecture on the effects of climate change, the human activities that scientists
claim are contributing factors and the ways by which people can modify their behavior to
try to slow climate change. - Answers -Assign students into groups that will research
climate change from reliable sources that both support and refute the evidence, then
divide the class into teams to debate the evidence on both sides of the argument.
A teacher wishes to assign a research project about organelles in eukaryotic cell in a
class. Which of the following action should the teacher do to clarify project evaluation
criteria?
Provide the students with numerical grades that represent excellent, good, or poor
projects.
Provide the students with a detailed rubric for the project.
Provide the students a list of reliable websites that have examples of similar projects.
Provide the students with clearly written, detailed directions for the project. - Answers -
Provide the students with a detailed rubric for the project.
A biology laboratory exercise requires that pairs of students dissect frogs and that each
student independently complete a worksheet relating observations made during the
dissection to basic knowledge of anatomy and physiology. A couple of students in the
class are reluctant to view or perform the dissection. Which of the following is the best
way for the teacher to respond to the reluctant students?
The teacher should excuse them from the exercise but tell them to complete the
worksheet, using their textbook as a reference.
The teacher should encourage them by saying that most students are willing to perform
the dissection, so they must do so as well or they will be marked down on the exercise.
The teacher should provide an alternative way for the students to perform the
dissection, such as with physical models or a web-based interactive simulation.
