Final answer:
Cutting sheets correctly requires precise measurements and careful folding. For example, for a gnomon, the paper is divided, corners are cut and removed, and scored lines are folded to form proper angles. The correct format is essential for the project's functionality.
Step-by-step explanation:
To cut the sheet for constructing a gnomon or for another educational project, follow these steps:
- Cut a 15 cm × 15 cm piece of aluminum foil with a utility knife and straight edge, adding a slit in the center.
- For paper tasks, cut along a marked line, dividing the paper for the gnomon and the base.
- Remove the marked corners on the gnomon piece and fold it down the center, keeping printed lines visible.
- Cut out along a curved line on the folded gnomon, starting near the top, but do not separate any pieces.
- Score and fold secondary lines on the gnomon to form 90-degree angles, allowing the triangular gnomon to rise above the base.
- Prepare the base by cutting from the apex up to a cross-line, and then sliding the fin of the gnomon into this slit.
- When using other materials such as butcher paper or tubing, measure and cut a strip according to the specified dimensions.
Remember to score stiff paper before folding to ensure straight folds. Use these methods to achieve the correct format for your educational projects.
