Core Skills Analysis
Science
- Eros explored how interlocking gears fit together, providing an early hands-on experience with mechanical systems and how one part can interact with another.
- Eros observed that the gears have repeated teeth and circular shapes, encouraging attention to structure, movement, and patterns in designed objects.
- By handling the colorful gears, rulers, and craft materials in the KiwiCo activity, Eros practiced observing materials and considering how tools can be used to investigate or build something.
- Eros engaged in an age-appropriate engineering experience: manipulating parts, testing how they connect, and developing curiosity about how simple machines work.
Tips
Tips: Invite Eros to slowly turn one gear and watch whether the neighboring gear moves in the same or opposite direction. Add a third gear and ask him to predict what will happen before testing it. Use the rulers shown in the activity to compare the sizes of different objects or to measure how far a gear moves after one turn, without requiring precise written answers. Encourage Eros to draw his gear arrangement and explain what he noticed using words such as turn, teeth, connect, faster, and slower. His focused, hands-on participation suggests an opportunity to build confidence through open-ended experimentation and celebrating predictions that lead to new discoveries.
