Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer uses a series of probing questions to ask the student to explain terms she used such as "evaporate," "water vapor," and "steam." The segment is useful in showing that while the student may use these terms, she may not understand their meaning and has some naive ideas about the difference between water vapor and liquid water.
