Grade: 3 - Engineering 2

3.E.2
Construct and compare multiple plausible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

I Can Statements Academic Vocabulary
I can construct plausible solutions to a problem based on criteria and constraints of the problem.

I can compare multiple plausible solutions to a problem based on how well they meet the criteria and constraints of
the problem.

Cross Cutting Concepts
Structure and Function
*The way an object is shaped or structured determines many of its properties and functions.

Cause and Effect
*Events have causes, sometimes simple, sometimes multifaceted. Deciphering causal relationships, and the mechanisms by which they are mediated, is a major activity of science and engineering.

Looking Back Looking Ahead
Develop a simple sketch, drawing, or physical model to illustrate and investigate how the shape of an object helps it function as needed to solve an identified problem. (K-2.E.2) Evaluate competing design solutions using a systematic process to identify how well they meet the criteria and constraints of the problem. (6-8.E.2)

Analyze data from investigations to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success. (6-8.E.3)
