1. What did I learn during Week #? Dimensionless objects are objects whose size are less then the distance they covered. The second model states that we always need a frame of reference, For example, it would be silly to say a person sitting down is not moving. The reason for this is that the person is really moving in reference to perhaps an astronaut standing on the moon since he/she is standing on Earth, which is continuously moving. However, the person sitting down is not moving in reference to the ground. Therefore, we should always mention in reference to what we're talking about, in other words, a reference frame.
We are currently studying kinematics, a branch of mechanics that describes how objects move. Its goal is to predict the position of an object. How can we describe motion? We can describe it by using measures such as velocity and acceleration. Velocity, a vector quality, is displacement, a vector representing the shortest distance from the initial to the final position of a motion, over a certain time ( The final topic we covered was free-fall. A free-falling object is any object that accelerates up or down under the influence of gravity. Free fall is represented by g, whose magnitude is equal to 9.8 m/s2. Free-fall is just a model since it doesn't really exist on Earth. It could only exist if there were no air resistance, which Earth of course lack. Here are the important equations we learned:

Weekly Reports give students an opportunity to reflect on their new knowledge, ask questions about unclear ideas, and explore the value of question asking itself. By reading the report, an instructor may:

2. What remained unclear to you?
3. What questions would you ask if you were the professor to determine whether your students understood this material?
b) Give an example of an adaptation. Explain what you think causes it and how it helps the species. c) What are the three conditions of natural selection? d) What does William Sutherland's "Genes map the migratory route" tell us about the blackcap's navigational abilities? Include the navigational skills of the young. e) What is the third environment? f) What is habitat selection? Give an example. |

3. What questions would you ask if you were the professor to determine whether your students understood this material?
b) How does environmental change X relate to species Z? c) What is the consequence of arriving at a design affecting the environment without analyzing the organisms present in that environment? d) Does the species ever affect the environment, or does the environment ever adapt due to its relationship to an organism?

3. What questions would you ask if you were the professor to determine whether your students understood this material?
b) What is ecology? c) What does an ecosystem consist of? d) What do we mean by saying natural selection is survival of the fittest? e) Why do birds who live on surface water catch fish? f) Name three different types of orientations cues. 2. What remained unclear to you? The only questions I have are on the subject of water surface tension, density and the way water temperature and currents influence the oceans. I did not understand the example of the pond and fall and spring overturn and its relationship to water density. Prof. E was going very fast on this subject and the overhead he put up was difficult to read.
