Reflection: Developing a Conceptual Understanding Material Engineers Part 2 - Section 3: Testing 1, 2, 3

 

In the revised lab packet, I included a checklist for students to refer to when developing a measurable test. I think it would also be worthwhile to create an anchor chart on the 'elements of a measurable test" with the students.

The 'measurable test' anchor chart and the lab checklist both help build an important schema for working and thinking like a scientist.

Possible elements to develop:

- will the procedure help answer the question and/or support the hypothesis

- is the procedure set up in a way to measure one variable, using standard units

- can someone else follow the procedure

Will my second graders completely grasp this concept? They will for where the are developmentally, and each time this concept is discussed and explored their schema becomes more refined with each discussion and lab experience.

Material Engineers Part 2

Unit 5: Unit 5 Matter and Its Interactions
Lesson 7 of 11

Objective: SWBAT test and explain which material demonstrates the selected property the best, based on measurable data.

Big Idea: Material Engineers use measurable procedures (fair test) to test materials for absorbency, hardness and flexibility.
