Essential Science for Teachers: Physical Science

Review the physical science concepts needed to teach today's standards-based curricula in this video course for elementary school teachers.

Essential Science for Teachers: Physical Science is available at archive.learner.org/resources/series200.html

 

A video course for grades K-6 teachers; 8 one-hour video programs, course guide, and website.

By exploring topics that range from the essential properties of aluminum foil to the plasma that makes up the sun, Essential Science for Teachers: Physical Science provides participants with enhanced understanding of content and how it connects to the elementary school classroom.

Essential Science for Teachers

Essential Science for Teachers courses are designed to help K-6 teachers gain an understanding of some of the bedrock science concepts they need to teach today’s standards-based curricula. The series of courses includes Life Science, Earth and Space Science, and Physical Science.

Physical Science consists of eight one-hour video programs accompanied by print and Web materials that provide in-class activities and homework explorations. Real-world examples, demonstrations, animations, still graphics, and interviews with scientists compose content segments that are intertwined with in-depth interviews with children that uncover their ideas about the topic at hand. Each program also features an elementary school teacher and his or her students exploring the topic using exemplary science curricula. Use the complete course for teacher education or professional development, or individual programs for content review.

Course Overview

What does a block of wood have in common with a cluster of galaxies billions of light years away? What about a giant sequoia tree in a rare coastal rainforest and the grains of sand found on beaches all over the world? The answer lies in what each is made of: matter. Matter is a fundamental concept in all of the sciences that links the infinitesimal world observed under a microscope to the vast reaches of space revealed by the world’s most powerful telescopes. It is what we and everything else are made of.

Matter is a topic that can be an integral and engaging part of science learning at all educational levels — starting in grades K-6 or even earlier. In the elementary school, a study of matter provides the foundation for understanding the physical nature of all things. Essential Science for Teachers: Physical Science is a content course designed to help K-6 teachers enhance their understandings of matter as one of the “big ideas” in the physical sciences. The main goal of this course is to provide teachers with learning opportunities that will directly inform their own classroom practice. To do this, the course addresses concepts that are appropriate at a variety of grade levels and does so in a cyclic manner, revisiting concepts at more sophisticated levels as the course progresses.

Essential Science for Teachers: Physical Science is one in a series of three video-, print-, and web-based science courses for elementary school teachers. These courses will help teachers better understand the science concepts that underlie the content they teach. Other courses include Life Science and Earth and Space Science.

Physical Science is composed of eight three-hour sessions, each with a one-hour video program addressing a topic area related to matter that is likely to be part of any elementary school science curriculum. Posing the question “What is matter?”, Session 1 begins the course by generating a working definition of matter, followed by an introduction to the properties of matter and classification. Session 2 focuses on modeling in science by looking at historical models of matter followed by closely examining the model that is used today: the particle model. Sessions 3 and 4 introduce what happens on a molecular level when matter changes state or is mixed with other matter, which leads to a distinction between physical and chemical changes. In Sessions 5 and 6, the particle model is extended to explore why matter rises or sinks. Finally, Sessions 7 and 8 highlight the interplay between energy and matter as heat, forces, and the effects of unusual conditions on matter are investigated.

Essential Science for Teachers: Physical Science also focuses on the ideas that children bring to the classroom about these topics. In order to keep the content grounded at the elementary school level, we interview and observe children in a clinical setting — what we call the “Science Studio” — to uncover their thinking. The research literature shows that their ideas are typical of students in the K-6 age group. The video content is supplemented in print and web materials by a bibliography that suggests readings from the research literature.

Each program also features one or more elementary school classrooms where a teacher and her students explore the topic using exemplary curriculum materials. A curriculum spokesperson may be interviewed to provide insight into the importance of the topic at the elementary school level. Finally, interviews with one or more scientists and/or science historians offer applications of important concepts to real examples, past and present.

By exploring topics that range from the essential properties of aluminum foil to the plasma that makes up the sun, Physical Science strives to provide participants not only with enhanced content understandings, but also with understandings of how this content connects to the elementary school classroom.

Course Structure

On-Site Activities

Essential Science for Teachers: Physical Science consists of eight sessions, each of which includes group activities and discussions as well as an hour-long video program. Weekly sessions, which should be scheduled for approximately three hours.

This guide provides activities and discussion topics for pre- and post-viewing investigations that complement each of the eight one-hour video programs.

Getting Ready (Site Investigation)
In preparation for watching the program, you will engage in 60 minutes of investigation through discussion and activity.

Watch the Course Video
Then you will watch the 60-minute video, which includes classroom footage, commentary, science demonstrations, and more.

Going Further (Site Investigation)
Wrap up the session with an additional 60 minutes of investigation through discussion and activity.

Between Sessions

Homework Assignments
Each session will contain the following homework activities. All participants should complete the assignments marked with * — the Reading Assignment, the Problem Set, the Ongoing Concept Mapping, and Preparing for the Next Session. Participants taking the course for graduate credit must complete all of the listed assignments, including those described in the Graduate Course Requirements section.

Note: Required Hours for Graduate Credit: If you are taking this course for graduate credit, the complete set of homework activities has been designed to fulfill the additional three hours required per session. The time taken to complete each assignment will vary among individuals, so no time estimates have been given. Each assignment will result in some form of evidence of learning. This evidence may be useful in building a portfolio for course assessment purposes.

Reading Assignment*
Reading Assignments will help you to draw connections between the session topics and research on children’s ideas. Readings will be discussed at the session that follows their assignment. The readings can be found in the Appendix.

Physical Science Problem Set*
Each session will be accompanied by a problem set that will reinforce content learning by asking questions that apply or extend physical science concepts addressed in the video. Possible answers for the problem set will be provided at the end of the session materials. It should be emphasized that many questions have a variety of answers – answers that vary depending on the understandings of the person answering the question. The intent is not to give you “right answers,” but to allow you to compare yours with more advanced learners in physical science.

Ongoing Concept Mapping*
Within each session, several fundamental concepts are explored. Beginning with Session 2, the creation of a concept map will provide you with an opportunity to reflect on your evolving understandings of these concepts and their connections to one another, as well as to see how the content in each session relates to that of other sessions. A more detailed explanation of concept mapping is included in Session 2.

Guided Journal Entry
As you proceed through this course, one way of building and connecting understandings is to reflect upon your learning as you go. In each session, one or more questions will be suggested to guide a journal entry. At the end of the course, these entries should help you see how your ideas have progressed.

Textbook Reading Suggestions
We strongly recommend that you acquire a college-level physics text to refer to in this course. Reading topics will be listed in each session, and can be located in most textbooks in the Table of Contents or Index.
Preparing for the Next Session*

This section will get you thinking about upcoming topics and remind you to bring materials needed for the next session’s activities.

Individual Workshop Descriptions

Workshop 1: What Is Matter? Properties and Classification of Matter
Matter is all around us — it’s what we and everything else are made of. Yet how do we define matter? What are the properties of matter that set it apart from something that is definitely not matter, such as light? In this session, participants build a working definition of matter, distinguish among the different forms it can take, investigate the difference between “essential” and “accidental” properties of matter, and look at the role of classification in science. Go to this unit.

Workshop 2: The Particle Nature of Matter – Solids, Liquids, and Gases
What simple idea links together all of chemistry and physics? How can a close study of the macroscopic differences among solids, liquids, and gases support a microscopic model of tiny, discrete, and constantly moving particles? In this session, participants learn how the “particle model” can be turned into a powerful tool for generating predictions about the behavior of matter under a wide range of conditions. Go to this unit.

Workshop 3: Physical Changes and Conservation of Matter
What happens when sugar is dissolved in a glass of water or when a pot of water on the stove boils away? Do things ever really “disappear?” In everyday life, observations that things “disappear” or “appear” seem to contradict one of the fundamental laws of nature: matter can be neither created nor destroyed. In this session, participants learn how the principles of the particle model are consistent with conservation of matter. Go to this unit.

Workshop 4: Chemical Changes and Conservation of Matter
How can the particle model account for what happens when two clear liquids are mixed together and they produce a milky-white solid? What happens when iron rusts? Where do the elements come from? In this session, participants extend the particle model by looking inside the particles, learn about some early chemical pioneers, and in the process discover how the law of conservation of matter applies even at the scale of atoms and molecules. Go to this unit.

Workshop 5: Density and Pressure
What makes a block of wood rise to the surface of a bucket of water? Why do your ears pop when you swim deep underwater? In this session, participants examine density, an essential property of matter. They also look at how particles of matter are in constant motion, which leads to a deeper understanding of fluid pressure. Lastly, the concepts of pressure and density are investigated to explain the macroscopic phenomenon of rising and sinking. Go to this unit.

Workshop 6: Rising and Sinking
Why does a hot air balloon rise into the sky? Why does ice rise in water, when a lump of solid wax will sink in a jar full of molten wax? In this session, participants generalize the model that has been developed about what rises and what sinks, using the idea of balance of forces. Go to this unit.

Workshop 7: Heat and Temperature
What makes the liquid in a thermometer rise or fall in response to temperature? Which contains more heat — a boiling teakettle on the stove or a swimming pool of lukewarm water? In this session, participants focus on the difference between heat and temperature, and examine how both are defined in terms of particles. The particle model is then used to explain a number of everyday phenomena, from why things expand when they are heated to the role that temperature plays in changes of state. Go to this unit.

Workshop 8: Extending the Particle Model of Matter
In this session, participants extend their understanding of the particle model to explain additional macroscopic phenomena, including the electrical properties of matter. Participants review the progression of ideas covered in the course and anticipate future developments in the understanding of matter. Go to this unit.

Wolfgang Ketterle
Dr. Ketterle is a principal investigator in the Atomic, Molecular and Optical Physics group in the Research Laboratory of Electronics at MIT. He is one of the three 2001 recipients of the Nobel Prize in Physics. Dr. Ketterle’s research activitiesfocus on ultracold neutral atoms at high densities. Such systems offer exciting new possibilities: When the atoms’ De Broglie wavelength is comparable to atomic dimensions (the range of the interaction potential), they exhibit novel collisional properties. For interatomic separations approaching the wavelength of light, one expects novel features in light scattering and spectroscopy. Of particular interest are quantum statistical effects such as spin waves and Bose-Einstein condensation. The latter occurs when the De Broglie wavelength becomes comparable to the interatomic spacing.

In order to obtain dense samples of ultracold atoms, Dr. Ketterle’s group uses a variety of techniques: slow atomic beams, laser cooling, spontaneous light force traps, magnetic traps, and evaporative cooling. The development of novel trapping and cooling schemes is a major part of his research activities. The recent observation of Bose-Einstein condensation allows him to study ultracold matter in a completely new regime. A Bose condensate is a coherent cloud of atoms with a a macroscopic population of the ground state of a trap.

Dr. Ketterle’s short-term goal is to study and understand the properties of a Bose condensate. In the long term, his group plans to use coherent atoms for precision measurements and atom optics.
