Evidence

Home Andree's Evidence: I gave all of my students one of the probes from the NSTA pre-assessment books about boiling (What is in the bubbles?). I tallied the responses and wrote a brief summary/analysis of the results that I will bring. In addition, I asked for student volunteers to meet with me and answer the following three questions: 1. Why does sweating cool us down? 2. What happens to the temperature of water when it boils? 3. How can we smell a smelling bar of soap? I had seven students respond to these verbally, and I have notes from their responses that I will bring.

Ivy's Evidence: I gave the following questions to 5 science student teachers in my program as well as 15 college prep chemistry high school students. (Many of the replies from the students are "I don't know.") Responses will be brought to spring meeting. hydregen,
 * 1. What is in the bubbles that form when water is boiling? **
 * 2. At what temperature does water boil? How does the temperature of water change while it is boiling? **
 * 3. Describe what happens to the boiling point of water when you go to the top of a tall mountain. **
 * 4. Describe and/or sketch the motion of molecules of solid, liquid, and gaseous water. **
 * 5. Why does ice float? **
 * 6. Why does sweating cool us down? **
 * 7. If you leave a cold glass of water outside on a hot day, you will see water droplets on the side of it. Why? **
 * 8. What will happen to a slushy ice-water mixture if it is put in a freezer at exactly 0C? **
 * 9. If I leave a glass of water on a counter for several days, the volume will decrease. Why? **
 * 10. Name a chemical in this room that is frozen.

Tracy's Evidence **


 * video asking students the following question (more or less): "how do you smell (soap, skunk spray, etc.)?"
 * examples of responses to the following question for a class warm-up: "why is sweating a cooling process?" [[file:Warm ups- why is sweating a cooling process.docx]]
