The Sugar and Water Task is a set of assessment items to administer to students.
Uses: You could use a task like this before teaching structure of matter to get a better idea of students’ baseline, or afterwards to assess progress. Or you could pick one or two questions to use at the start of each class period as a warm up.
The answer key indicates correct answers for the assessment items. The key also tells you the target level for each question: the level within either the Structure of Matter or Argumentation learning progression that a correct answer indicates.
There are descriptions of both the Structure of Matter and the Argumentation learning progressions. Each progression is broken down into levels 0 through 3 (least to most sophisticated). By using the assessment items and answer key to locate a student on the construct map, you can better understand the student’s level of conceptual mastery.
