The Great Eggscape: Applying Newton’s Laws to Impact Engineering
Inquiry Framework
Question Framework
Driving Question
The overarching question that guides the entire project.How can we engineer a landing module that applies the principles of Newton’s Second Law and momentum to protect a fragile payload during a high-velocity impact within strict design constraints?Essential Questions
Supporting questions that break down major concepts.- How does Newton’s Second Law ($F=ma$) help us predict and control the force an egg experiences during a collision?
- How can we manipulate the variables of time and impact force to ensure a fragile payload survives a fall?
- How do the mass and velocity of our contraption affect the momentum that must be neutralized upon impact?
- In what ways do engineering constraints (such as limited materials, weight limits, and height) drive innovation in the design process?
- How can mathematical models and data analysis from initial failures be used to justify specific design improvements?
Standards & Learning Goals
Learning Goals
By the end of this project, students will be able to:- Students will calculate the impact force and momentum of their contraption using Newton’s Second Law ($F=ma$) and the Impulse-Momentum Theorem ($F\Delta t = \Delta p$) to predict the success of their design.
- Students will apply the engineering design process to build, test, and iterate on a landing module that protects a fragile payload, adhering to specific material and weight constraints.
- Students will analyze data from trial drops to identify the relationship between impact time and force, using this evidence to justify specific modifications to their contraption.
- Students will evaluate the effectiveness of various materials and structural designs in absorbing kinetic energy and increasing the duration of the collision.

Entry Events
Events that will be used to introduce the project to studentsThe Humanitarian 'Cargo Drop' Crisis
Students enter to a 'breaking news' broadcast about a failed high-altitude delivery of fragile medical supplies to a remote disaster zone. They are tasked as 'Rapid Response Engineers' to analyze the crash site data and design a passive landing system that uses Newton's Second Law to ensure the next delivery (an egg) survives a terminal velocity drop.The Bio-Mimicry Armor Challenge
Students examine a variety of nature's 'impact specialists,' from the thick skull of a bighorn sheep to the fibrous shell of a coconut. They are challenged to 'bio-hack' these natural designs to create a synthetic contraption that mimics biological protection, evaluating their solutions against the constraints of weight and material cost.Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.The Beta-Drop & Impulse Lab
In this activity, students build a 'Beta' version of their module and conduct controlled test drops from a lower height. Using slow-motion video analysis or accelerometers (if available), they will measure the time it takes for the device to come to a complete stop upon hitting the ground. They will then graph the relationship between impact duration and peak force.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityAn 'Impulse Interaction Graph' and a 'Modification Memo' that identifies one specific structural weakness discovered during the beta test.Alignment
How this activity aligns with the learning objectives & standardsAligns with HS-PS2-3 and CCSS.MATH.CONTENT.HSF.IF.C.7. Students apply engineering ideas to minimize force and use graphing to visualize the relationship between time and force.Mission Debrief: The Engineering Evaluation
Students assemble their final 'Rapid Response' landing module, incorporating the modifications from Activity 3. After the final high-altitude drop, students must perform a 'Post-Mission Evaluation.' They will analyze why their egg survived or broke, focusing on the trade-offs between mass (which increases momentum) and protection (which increases mass).Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA 'Technical Design Portfolio' which includes the final device performance data, a photo of the 'post-crash' module, and a written argument justifying their final design choices based on physics data.Alignment
How this activity aligns with the learning objectives & standardsAligns with HS-ETS1-3 and HS-PS2-3. Students evaluate their final solution against constraints and refine their device to minimize force.The Impact Analyst’s Blueprint
Before building, students must act as 'Lead Analysts' to calculate the physical forces their egg will encounter. Using the scenario of a high-altitude drop, students will calculate the potential energy, final velocity at impact (ignoring air resistance initially), and the resulting momentum. This provides a theoretical baseline for the force their contraption must mitigate.Steps

What students will submit as the final product of the activityA 'Predictive Impact Report' containing all mathematical calculations, a free-body diagram of the falling payload, and a predicted 'Force of Impact' based on a 0.01-second collision time.Alignment
How this activity aligns with the learning objectives & standardsAligns with HS-PS2-1 (Newton’s Second Law) and HS-PS2-2 (Momentum). This activity requires students to use mathematical representations to predict how mass and velocity contribute to the force of impact.Rubric & Reflection

Proficient
3 PointsCalculations for momentum, velocity, and force are accurate and complete. Free-body diagrams correctly represent forces. Successfully uses the Impulse-Momentum theorem to explain how increasing impact time reduces force.
Developing
2 PointsMathematical representations are mostly correct but may contain minor calculation errors. Free-body diagrams are present but may lack proper labeling or scale. Shows an emerging understanding of the inverse relationship between time and force.
Beginning
1 PointsCalculations are incomplete or contain significant errors. Struggles to apply physics formulas to the physical contraption. Free-body diagrams are missing or fundamentally incorrect.
Engineering Design & Iterative Prototyping
The ability to break down the problem into sub-problems, prototype, test (Beta-Drop), and iterate based on data to meet specific constraints (weight, materials, height).
Exemplary
4 PointsThe final design shows innovative use of materials and a clear evolutionary path from the Beta version. Constraints are used as catalysts for creative solutions. The 'Modification Memo' provides deep, data-driven insights for the final iteration.
Proficient
3 PointsDesign follows a logical engineering process. The student identifies a clear failure point in the Beta test and makes a specific, effective structural change for the final version while staying within constraints.
Developing
2 PointsA prototype and final version were built, but changes between the two are superficial or not clearly linked to Beta test data. Some constraints (like weight) may have been overlooked.
Beginning
1 PointsLittle to no evidence of iteration. The final design is essentially the same as the initial idea despite test results. Failed to adhere to materials or weight constraints.

2 PointsGraphs are provided but may lack clear labels or have inconsistent scaling. The connection between the graph and the physical design is present but weak or poorly explained.
Beginning
1 PointsData collection is disorganized or incomplete. Graphs are missing, incorrect, or do not reflect the actual testing conducted. Analysis is purely descriptive rather than data-driven.
Evidence-Based Argumentation & Reflection
Quality of the Technical Design Portfolio and written arguments, specifically the ability to justify design choices using evidence from physics data and test results.
Exemplary

Proficient
3 PointsArguments are clear, logical, and supported by data. The student provides a coherent explanation for the egg’s survival or failure and addresses the trade-offs between mass and protection.
Developing
2 PointsThe final report is complete but relies more on observation than physics data. Argumentation is general (e.g., 'it needed more padding') rather than quantitative. Reflective elements are present but basic.
Beginning
1 PointsPortfolio is incomplete or lacks a clear argument. Conclusions are not supported by the data collected during the project. Fails to link the final outcome back to the driving question.
