Resistance Trace Bag
Steps:
- Adult Prep: Fill a gallon-sized Ziplock Bag halfway with corn kernels. Add a small amount of water to create a thick, dense texture that is resistant to movement.
- Seal the bag tightly, ensuring all excess air is removed. Place the sealed bag flat inside a shallow plastic container to stabilize it on the table.
- Use a marker to draw simple lines, letters, or shapes (like a circle or a cross) directly onto the outside of the bag.
- Challenge your child to use only their pointer finger (finger isolation) to press hard into the bag, tracing the marker lines.
- They must use sustained pressure to push the kernels aside, leaving a visible path in the resistant medium. This requires great effort!
- When finished, gently shake the bag to reset the kernels. Use a damp paper towel to wipe the marker lines off the bag and start with a new shape.
Safety Tip:
Constant and direct adult supervision is required. Ensure the Ziplock Bag is sealed completely before use, as corn kernels pose a choking hazard if ingested.
