Force Pairs & Peaks
L1 Phenomenon 100
In Lesson 1, teachers and students used this plastic household item as an inexpensive substitute for a smartphone during breaking demonstrations.
L3 Core Claim 100
Our central consensus claim from Lesson 3 states that this happens to ALL solid objects when pushed in a collision, even stiff glass and metal.
L4 Thresholds 100
The maximum amount of force or deformation a solid object can take and still spring back to its original resting shape.
L5 Minimums 100
The minimum number of interacting objects or bodies required in any system in order to produce contact forces.
Collision Types 200
In our Lesson 1 classification, this letter represents a collision where a moving fragile object collides with a motionless object (like dropping a phone).
L3 Lab Apparatus 200
To magnify microscopic bending of rigid glass, students reflected this focused beam of light off a small mirror stuck to the glass onto a wall.
L4 Damage Limit 200
The critical amount of force or deformation beyond which a material can no longer stay intact and actually cracks, fractures, or splits apart.
Force Pair Rules 200
When any two objects make contact, the contact forces they exert on each other are always equal in strength and have this relationship in direction.
Collision Types 300
This collision type letter describes when a motionless fragile object is struck by another moving object, like accidentally dropping a heavy backpack onto a phone.
Glass Deflection 300
In the glass investigation, resting this container filled with small dense items in the middle of the glass caused the reflected laser dot to shift position.
Tested Materials 300
In the Material Deformation Lab, students used push-pull spring scales to test two strip materials bridging two bricks: wood stirrers and this foam material.
Impact Force 300
The term for the maximum amount of contact force reached at the point of greatest deformation during the brief instant of a collision.
DQB Mission 400
The exact overarching question written at the top of our Driving Question Board (DQB) that guides all investigations in Unit 8.1.
Video Evidence 400
In Lesson 3, students watched a 64x timelapse video of engineers load-testing this massive roadway structure to prove concrete visibly bends before breaking.
Deformation Factors 400
Besides material type, name the other TWO structural characteristics of an object identified in Lesson 4 that affect how much it deforms under a given force.
Lab Innovation 400
In the cart collision lab, students wrapped this simple household item around the spring scale plunger to record the maximum peak force reached.
Physics Concept 500
Rotating the collision diagram on chart paper demonstrated that changing this perspective choice does not alter what is moving and what is stationary.
Word Wall Term 500
The formal scientific term added to our Word Wall in Lesson 3 for a push or pull that an object experiences due to touching another object.
Graph Analysis 500
On their Force vs. Deformation scatter plots, students used a ruler to draw this linear model through the open-circle data points that returned to shape.
Modeling Convention 500
In physics and engineering, this single-object drawing isolates one body from its surroundings and uses straight arrows to show external forces acting upon it.
Jeopardy Rule: Responses must be phrased as questions (e.g., "What is elastic limit?").

Game Total: 6,000 Pts Aligned to Lessons 1–5
Cat. 1: Collision Types & DQB
Lesson 1
100 PTS: What is a CD case?
Used as a safe, breakable manipulative substitute for real phones.
200 PTS: What is Type A?
Motion pattern: moving fragile object hits motionless surface/object.
300 PTS: What is Type B?
Motion pattern: stationary fragile object struck by a moving body.
400 PTS: What is "Why do things sometimes get damaged when they hit each other?"
The official unit question posted on the class Driving Question Board.
500 PTS: What is frame of reference?
PS2.A DCI concept: positions and motions depend on chosen reference frame.
Cat. 2: Laser & Bending Tests
Lesson 3
100 PTS: What is they bend / change shape (deform)?
Lesson 3 core discovery: all solid objects bend when force is applied.
200 PTS: What is a laser pointer (or laser beam)?
Reflected laser apparatus magnified small shape changes onto the wall.
300 PTS: What is a cup of rocks (sand or washers)?
Static weight applied a downward contact force, deflecting the laser dot.
400 PTS: What is a concrete beam (double-tee bridge joint)?
64x timelapse video showed massive concrete bending prior to cracking.
500 PTS: What is a contact force?
Official Lesson 3 Word Wall term: force experienced only when touching.
Cat. 3: Limits & Trend Lines
Lesson 4
100 PTS: What is the elastic limit?
Point beyond which permanent shape change (plastic damage) occurs.
200 PTS: What is the breaking point?
Point beyond which the material cracks, splinters, or fractures.
300 PTS: What is Styrofoam (foam strips)?
Tested in single and double thicknesses alongside wood stirrers.
400 PTS: What are shape and thickness?
3 factors identified: material type, shape, and thickness.
500 PTS: What is a line of best fit (trend line)?
Mathematical model showing the linear elastic response up to limit.
Cat. 4: Force Pairs & Peaks
Lesson 5
100 PTS: What is at least two objects?
A single object cannot exert a force on itself; forces come in pairs.
200 PTS: What is opposite (or in opposite directions)?
Forces act along the same interaction line in strictly opposite directions.
300 PTS: What is peak force?
The maximum spike in contact force recorded during maximum deformation.
400 PTS: What is a twist-tie collar?
Pushed along the spring scale plunger to record peak compression distance.
500 PTS: What is a free body diagram?
Subsystem model isolating one body with arrows showing external forces.
1. Buzzer & Selection Teams rotate board control. The first team to buzz in has 15 seconds to respond.
2. Phrasing & Steals Answers must begin with "What is...". Incorrect answers deduct points and allow steals.
3. Final Jeopardy Tiebreaker "A company claims an unbreakable phone screen. Based on Lesson 4, why can no solid be truly unbreakable?"
