Texts: 1. Krauskopf & Beiser, The Physical Universe (Twelfth Edition): McGraw-Hill, 2008.

2. Physical Sciences for Elementary Education, Laboratory Manual, Messiah College, Spring 2008. A calculator will be required in the laboratory.

Course Objectives: The course aims to provide elementary education majors with the foundation and understanding necessary to teach physical science in an elementary school.

Physical Sciences for Elementary Educationmeets the General Education Laboratory Science requirement. The objectives for such a course are:

These objectives are fulfilled by the following specific learning objectives for this course:

1. To understand the methods by which scientific knowledge is acquired.

2. To learn the principles and basic content of each area of physical science, and use the principles to understand and explain specific examples.

3. To focus attention on areas where common sense is not in agreement with the results of careful scientific investigation.

4. To involve students in applying these methods and principles in the laboratory through experiences with the kinds of equipment likely to be available in an elementary school.

Written Paper:

Choose one of the topics below. Write a one- to two-page explanation of the topic. A diagram may be included if that is helpful. Consult the Messiah College Student Handbook for policy concerning plagiarism. The paper should be typewritten and double spaced. It is due in class on Thursday, April 24, 2008. (One point will be deducted for each day late. No paper will be accepted after the final test on May 8.)

Assume that you are writing your explanation for someone who is not in this course. Begin with facts and ideas that are known and understood by everyone. Then add definitions, generalizations, or models which are important to your topic. Finally give a clear and logical explanation of your topic using those principles. This will usually involve applying the general knowledge to your specific situation in a step-by-step fashion. It is important to specifically address the question given, rather than just write about the general subject. Avoid extraneous material that does not lead to a clear understanding of the main point. In particular, the introduction and conclusion of this paper should be rather short.

1. Consider a pan of boiling water sitting on an electric hot plate. Heat is continuously entering the water from the hot plate. However, the temperature of the water stays constant at 100 degrees Celsius. Explain, in terms of energy, why the water temperature does not rise, even though heat energy is continuously entering the water. What would happen if the hot plate were turned to a higher setting? Explain.

2. If you are standing by a road and a car drives past you with its horn blowing, the pitch of the horn changes just as the car passes you. Explain why this is true, based on the wave nature of sound. Since light also exhibits some wave properties, a similar color change can occur with light. Explain how a color change is used to determine the speed of a moving galaxy.

3. The time from when the sun is directly overhead, until it is directly overhead again, is 24 hours. This is called a solar day. The time from when a star is directly overhead, until it is directly overhead again, is 23 hours, 56 minutes, and 4 seconds. This is called a sidereal day. Explain why these two are different.

4. When a body of air rises to higher altitude where the atmospheric pressure is lower, it undergoes adiabatic cooling. This in turn causes the relative humidity of the air to increase, and may lead to cloud formation. First explain why cooling occurs. Then explain how this causes an increase in relative humidity, and how this can lead to cloud formation.
