DAILY OBJECTIVES:
8.iii Describe the distinction amongst the three states of matter and explain in terms of the kinetic theory, how they can be inter-converted
LESSON:
D block: (1) Collect assignment (Energy powerpoint) (2) Students should diagram "phases - or states - of matter" as a triangle and determine the name of each phase transfer (ie. what is it called when a solid changes into a liquid? Answer: melting) Add to the name of the phase transformation a simple description of "add heat" or "remove heat." (3) Students go to "misconception" page. Students should individually select one misconception and design an experiment to "disprove" it. Due in writing, on paper, at the beginning of next class.

ASSIGNMENT:
D block: (1) Students make phase change triangle, labeling three phases of matter, name of process of each phase change, and whether phase change absorbs heat or releases heat. Do this on one piece of loose, lined paper. Title paper, "Phases of matter and how they interconvert." Place name, date and block in the upper right hand corner. More credit will be given to neat work than to messy or sloppy work. (2) Using the "misconception" you select, make up an experiment to test it. On a new piece of lined, loose leaf paper, place name, date and class in the upper right hand corner. Title the paper: "Misconception about heat transfer." First write down the misconception that you selected to test. Second, make a list of materials you will need for your experiment. Third, using numbered steps, design an experiment to disprove the misconception. This is due at the beginning of next period.
F block: Same as D block, above.
