Plan an investigation to provide evidence of Newton’s Laws that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
The Nebraska College and Career Ready Standards for Science (2024) outcome SC.8.1.1.c (Physical Sciences) for Grade 8 says: “Plan an investigation to provide evidence of Newton’s Laws that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Nebraska College and Career Ready Standards for Science (2024).
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.
- Why do you lurch forward when a bus stops? 50–60 min
Students flick a card out from under a coin, then crash toy cars carrying loose clay passengers into a barrier and measure how far the passenger flies. They use their data to explain inertia and to design a better seatbelt.
- Why does a heavier cart hit harder? 50–60 min
Teams load a toy car with coins, roll it down the same ramp into a paper cup and measure how far the cup slides. They graph mass against slide distance and explain, with momentum, why a loaded truck is harder to stop than a small car.
