Core Skills Analysis
Math
- Measured and compared launch distances and heights using informal units (e.g., "blocks" or "hand‑spans"), building early estimation skills.
- Recorded data in simple tables, practicing organization, counting entries, and recognizing patterns across trials.
- Compared results of slow versus hard forces, introducing concepts of variable magnitude and its effect on numerical outcomes.
- Used the worksheet matching pictures to force types, reinforcing one‑to‑one correspondence and basic classification.
Science
- Identified different types of forces (push, pull, gravity, friction) through video discussion and picture matching.
- Explored Newton’s First Law (inertia) with the cup‑and‑index‑card demonstration, observing how objects resist change in motion.
- Formulated predictions (hypotheses) about which projectile would travel farthest, then tested and revised ideas based on evidence.
- Investigated variables such as object weight, material, and force intensity, practicing the scientific method of observation and measurement.
Tips
Extend the investigation by turning the catapult data into a simple bar graph on chart paper, letting students color‑code each projectile. Next, build a ramp‑launch station to compare linear motion with the catapult’s projectile motion, discussing how angle changes speed and distance. Invite children to write a short story from the viewpoint of the chocolate pumpkin, describing its "feelings" as it flies, which reinforces scientific vocabulary while encouraging creative writing. Finally, set up a classroom “Force Hunt” where kids find everyday examples of push, pull, gravity, and friction, documenting them with photos or drawings for a class collage.
Book Recommendations
- Ada Twist, Scientist by Andrea Beaty: A curious girl explores the world with questions and experiments, perfect for introducing scientific inquiry to young learners.
- Gravity Is a Mystery by Emily Sohn: A picture‑book that explains gravity and motion in simple, relatable scenarios for kindergarten‑grade 2 readers.
- The Catapult Club by Katherine J. B. Kelly: A fun story about kids building and testing catapults, linking narrative to basic physics concepts.
Learning Standards
- Ontario Curriculum, Science and Technology (Grade 1): Understanding movement and change – identifies forces, describes motion, and explains inertia (e.g., Overall Expectation 1.1).
- Ontario Curriculum, Mathematics (Grade 1): Measurement – uses informal units to compare lengths and distances (Overall Expectation M1ME).
- Ontario Curriculum, Mathematics (Grade 2): Data Management – collects, organizes, and interprets simple data sets (Overall Expectation M2DM).
- British Columbia Curriculum, Science (Grades K‑2): Forces – recognizes pushes and pulls, predicts effects of different forces on objects.
Try This Next
- Create a data‑record sheet with columns for projectile, force type (slow/hard), distance, and height; have students fill it after each launch.
- Design a "Build‑Your‑Own‑Catapult" drawing prompt where children sketch a new catapult, label its parts, and explain how each part changes the force applied.
