Mississippi Science FSL.2.1
The Standard
- FSL.2
- Students will identify, research, and communicate the development of technology and engineering practices.
Research and present a technology that was developed through engineering design. Identify its purpose, how it has advanced through alterations in design (e.g., systems that provide homes and businesses with utilities, parking structures, park and recreational structures, and traffic flow), and careers related to its use).

What This Standard Means
What Students Need to Do
- Students research a technology made through engineering design. They present what it does, how design changes improved it, and which workers use or maintain it.
What Mastery Looks Like
- A student can use sources to explain the purpose of a traffic signal and compare fixed timers with vehicle sensors. They can explain what problem the change addressed and describe a signal technician’s work.
Common Misconceptions
- Students may list newer features without explaining why the design changed. They may name a career, such as engineer, without saying what that person does.
How to Assess It
- Give students a short article about traffic signals. Ask for a 60-second presentation that names the purpose, two design changes, the problem each addressed, and one related job.

Ways to Teach It
Use toy cars and paper signal cards to model a timed intersection, then add a pedestrian phase and test whether crossings improve.
Ask students to write why a vehicle sensor might beat a fixed timer at a quiet intersection, using a printed fact sheet.
Give pairs diagrams of three signal designs to sequence, then have them match each design change to a traffic problem.
Have students sketch a nearby traffic signal, label one design feature, and look up what a city signal technician does.
