This afternoon, Onyx class investigated how light travels. They shone a torch through a series of holes in squares of card, and the light shone onto the end target. They found that when they moved a piece of card from the line, the light carried on travelling through the remaining holes to the target, but didn’t change direction to go through the moved hole.
Conclusion: LIGHT TRAVELS IN STRAIGHT LINES! 🔦
