Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
The Oklahoma Academic Standards for Science (2026) outcome MS.ETS1.1 (Engineering, Technology and Applications of Science) for Grades 6–8 says: “Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Oklahoma Academic Standards for Science (2026).
Forces and Motion: Crash, Push and Stop Grade 8
Why you lurch forward when the bus brakes, how fast a toy car really goes, why heavier carts hit harder, and how to build a crumple zone that saves an egg. Four lessons on inertia, speed, mass and stopping safely.
- Can you design a crumple zone? Two periods of 45–60 min (or one 75–90 min block)
Teams design, build and test a crumple zone that lets a raw egg in a zip bag survive a cart crash into a wall, working to a budget and a size limit. They measure how far each design crushed and use class data to explain why a longer stop means a smaller force.
