Core Skills Analysis
Mathematics
- Measured the weight shown on the scales, reinforcing concepts of mass and units (grams).
- Compared two measurements to determine a winner, practicing greater‑than/less‑than reasoning.
- Recorded launch results in a simple table, introducing data organization and basic graphing ideas.
- Estimated distances and angles before each launch, supporting skills in measurement estimation and rounding.
Science
- Observed how a lever‑type catapult converts stored potential energy into kinetic energy, illustrating simple machines.
- Explored cause‑and‑effect relationships: greater tension in the wood arm produced farther pom‑pom flights.
- Discussed the role of gravity and projectile motion as pom‑poms arced and fell onto the scales.
- Identified material properties of wood (elasticity, strength) that affect the catapult’s performance.
Design and Technologies
- Planned and sketched a catapult design before cutting wood, applying the design process (investigate, design, make, evaluate).
- Used hand tools safely, learning about tool selection, hand‑eye coordination, and workshop safety rules.
- Modified the prototype after test launches, demonstrating iterative problem‑solving and refinement.
- Considered how scale size and pivot placement affect launch force, linking engineering concepts to real‑world function.
English (Language Arts)
- Followed written step‑by‑step instructions, building comprehension and sequencing skills.
- Used specific vocabulary (catapult, projectile, tension, scale) in oral explanations, expanding scientific terminology.
- Described the experiment results using complete sentences, practicing clear communication of data.
- Collaborated with peers to discuss who won, encouraging turn‑taking and respectful argumentation.
Tips
Turn the catapult challenge into a mini‑science fair: have the child vary launch angles, arm lengths, or pom‑pom sizes and record each trial in a data table. Afterwards, guide them to create a simple bar graph comparing the masses measured on the scales and discuss patterns they notice. Encourage a storytelling element by asking them to write a short narrative about a “Catapult Championship” where each launch is a character’s turn, integrating math vocabulary and scientific concepts. Finally, let them redesign the wooden arm using cardboard or rubber bands, testing the new prototype and reflecting on what engineering changes improved performance.
