An engineer tests a design and discovers that it does not work well. What should the engineer do?
Make changes and improve the design.
What is a constraint?
Something that limits what you are trying to do.

Con
Mrs. Flores waters her plant for only 5 seconds every day. At the end of the week, the plant is brown and dry. What should she do to solve the problem?
She should change how she waters the plant, such as giving it more water.

Engineer
What is the final step after engineers have found a solution?
Communicate the solution
Name two possible pros of cars today.
Answers may vary. Examples include transportation and making it easier to travel.
An engineer creates a design, tests it, notices a problem, and changes the design. Why is this an important part of engineering?Considering both cycle time and water use, which design is the best overall choice?
Engineers use testing to identify problems and improve their solutions.
Mrs. Perdomo needs a solution that is safe, easy to build, and keeps her dry. She only has 1 rope and 5 pieces of wood. Which statement is correct?
Safe, easy to build, and keeps her dry are criteria; the rope, wood, and river width are constraints.
