The experiment aims to determine whether light travels in a straight line. Essential materials include blue tags, black paper, cardboard, a pair of scissors, and a torchlight. The procedure involves cutting holes in the papers, aligning them in a straight line, and using blue tacks to secure the paper and cardboard.

6. Conclusion - (Cloze passage with the KEY CONCEPT like in your workbook)
light will alwys travel in a straight line we can see light spreading because it shines on the objiects and the objects shine the ligt back into our eyes.
