building a pinhole camera to measure the size of the sun and the moon

Math

• Understanding the concept of angles and how they affect the size of the projection in the pinhole camera.
• Applying trigonometry principles to estimate the distance of the sun and the moon using the pinhole camera measurements.
• Using geometric concepts to calculate the size of the sun and the moon based on the projected images in the pinhole camera.
• Practicing measurement and estimation skills by comparing the projected images with known measurements of the sun and the moon.

For continued development, students could explore the historical significance of pinhole cameras in astronomy, such as how early astronomers used similar devices to study celestial bodies. They could also experiment with different pinhole sizes and distances to refine their measurements and understanding of the principles involved.
