Essential Science for Teachers: Physical Science Session 3. Physical Changes and Conservation of Mat
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.,The segment shows the interviewer trying to find out the student's id

In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is using questions to help guide the student's thinking about the difference in age between two mountains. He encourages her to look at her own drawing and compare what she has drawn to a representation of two mountains encountered earlier. The student changes her idea about which mountain is older by connecting the explanation she used in her own drawing to the representations use

Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer probes to find out if the student thinks atoms in a gas move. The student has the idea that gas atoms move freely but is limited by a model in which there are no boundaries. When presented with the phenomenon of air in a sealed bag, the student says they would stop because of the boundary. The student goes on to reason by use of an analogy that at recess time when you are free to go where ever you

In-depth interviews with children that uncover their ideas about the topic at hand.,This segment provides an example of probing questions and phenomena used to elicit the student's ideas about motion of particles in a liquid. The student has several ideas about why the particles move including bubbles that popped, pressure, "commotion," waves, etc. but seems to lack the idea that the particles in a liquid have greater energy, hence more motion. The interviewer probes further to find out if the s

In-depth interviews with children that uncover their ideas about the topic at hand.,The segment shows the interviewer providing the student with a sample of sand and asking her what it is. When she correctly identifies it as sand, he continues to ask questions which show that she has the prior knowledge that sand comes from rock and that it is made up of tiny pieces of rock.

In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is trying to find out the student's ideas about what would happen if you kept dividing a piece of aluminum foil. Would you eventually get down to an atom? The segment shows that the student understands the idea of very small parts made up of atoms but may have difficulty accepting the idea that a material like aluminum foil can ultimately be divided and end up with a single atom.

Mitochondrial Control Region
Every human cell has a "second" genome, found in the cell's energy-generating organelle, the mitochondrion. In fact, each mitochondrion has several copies of its own genome, and there are several hundred to several thousand mitochondria per cell. This means that the mitochondrial (mt) genome is highly amplified. While each cell contains only two copies of a given nuclear gene (one on each of the paired chromosomes), there are thousands of copies of a given mt gene per cell. Because of this high

"A Foretaste of the Orient": John Murray Criticizes the AFL
Most historians who have written about the 1903 strike of Mexican and Japanese farm workers against the Oxnard, California, sugar beet growers have relied on John Murray's first-hand account of the strike and its aftermath. Murray, a socialist union organizer, went to Oxnard after learning of the strike through newspaper accounts of strike-related violence and rioting. Along with fellow union organizer Fred C. Wheeler, Murray assisted the farm workers' union, the Japanese-Mexican Labor Associati

A Family Corresponds: Polish Immigrants in the Early 20th century
Many immigrants to the United States wrote letters back home. At the time they were written, the missives shaped the expectations of those who would soon make the same journey; today, they gave historians invaluable first-hand testimony of the immigrants' own experiences. These seventeen letters involved the children of a retired Polish farmer named Raczkowski. Adam Raczkowski went to the United States in 1904 with the financial assistance of his sister Helena Brylska [later Dabrowskis] and his
