Entry Events
Events that will be used to introduce the project to studentsFueling the Reaction
Students are presented with a 'broken' Rube Goldberg machine that ends in a lackluster whimper because the initial energy was too weak. They are challenged to design a machine that *only* works if the golf ball is hit with a specific velocity and accuracy, forcing them to master the key elements of manipulative skills to 'fuel' their creative invention.Mission: Kinetic Strike
Students receive a 'Top Secret' video transmission from the 'Agency of Kinetic Energy' explaining that a remote-access trigger is the only way to activate a safety mechanism from a safe distance. To 'save the mission,' students must undergo 'Elite Striker Training' to ensure their eye-on-target and body positioning are precise enough to hit a tiny pressure-plate trigger from 20 feet away.Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.The Stance Sculptors
Before hitting a ball, students must master the 'statue' phase of the golf strike. This activity focuses on the first two key elements: body position and eye on target. Students work in 'Pro-Caddie Pairs' to critique and mold each other’s form to ensure a solid foundation for the machine’s activation.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 'Strike Stance Scorecard' where partners have verified each other's grip, stance width, and eye alignment through three successful 'statue' holds.Alignment
How this activity aligns with the learning objectives & standardsAligns with TEKS.PE.4.1.A (Body position, eye on target) and TEKS.PE.4.1.B.golf (Correct golf club technique). Students focus on the foundation of the swing before adding power or complexity.Weight Transfer Wizards
Students transition from a static stance to a dynamic swing, focusing on shifting their weight from the back foot to the front foot and finishing with a high follow-through. They will practice hitting foam balls into 'Energy Zones' to understand how weight transfer affects the distance and speed of the ball.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 'Energy Transfer Log' documenting the result of 10 strikes, noting how many times the student successfully pointed their belt buckle toward the target during the follow-through.Alignment
How this activity aligns with the learning objectives & standardsAligns with TEKS.PE.4.1.A (Weight transfer, follow-through) and TEKS.PE.4.1.B.golf. This activity introduces the dynamic motion required to generate the kinetic energy needed for the Rube Goldberg machine.Architects of the Trigger
Students begin designing the 'First Domino' of their Rube Goldberg machine. They must create a trigger mechanism (e.g., a lever, a ramp, or a weighted switch) that will only be activated if struck by a golf ball moving at a specific velocity and trajectory.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 'Trigger Blueprint' and a physical prototype of the machine's starting mechanism that successfully reacts when struck.Alignment
How this activity aligns with the learning objectives & standardsAligns with NGSS.4-PS3-4 (Energy transfer and device design) and TEKS.PE.4.1.A (Eye on target). This links the physical movement to the engineering goal of the project.The Consistency Debugging Lab
Consistency is key for a Rube Goldberg machine. In this lab, students use video recording or peer observation to analyze their swing. They look for 'glitches' in their 4 key elements and work together to debug their technique so they can hit the trigger 4 out of 5 times.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 'Swing Debugging Report' where students identify one specific movement (e.g., 'I moved my eyes too soon') and document the correction they made.Alignment
How this activity aligns with the learning objectives & standardsAligns with SHAPE.S4.E1.4 (Responsible social behavior) and TEKS.PE.4.1.A (Practice key elements during dynamic activities). This activity uses social-emotional learning to improve physical performance.The Chain Reaction Assembly
It is time to build the full 'Chain Reaction.' Students connect their trigger to at least four other energy transfer steps (e.g., marbles, ramps, pulleys). The final challenge is that the machine is only allowed to be started by the golf strike—no hands allowed!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 fully constructed Rube Goldberg machine ready for the 'Live Strike' activation.Alignment
How this activity aligns with the learning objectives & standardsAligns with NGSS.4-PS3-4 (Design, test, and refine a device) and TEKS.PE.4.1.B.golf. Students must integrate their physical skill into the larger system.The Grand Activation Showcase
The grand finale! Students demonstrate their mastery of the golf strike to an audience. They must explain their technique (the 4 elements) and then activate their massive Rube Goldberg machine with one perfectly aimed strike.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
