Good morning Year Six, I hope you are all well and your lights are shining bright! Last week we looked at key vocabulary and went on a light hunt.
Today you will conduct an experiment at home (or school) using items you all have access to. The purpose of our experiment is to see in what direction light travels (hence the title straight or wavy?)
To discover how light travels and learn about the physics behind light.
I predict light travels in……. direction.
*3 pieces of paper/card
*Torch/ mobile torch
1. For each piece of card, use a ruler to draw lines connecting opposite corners of the card (creating a large X)
2. At the intersection of the two lines, cut a hole in the center of the cards.
3. For each card, use a small piece of blu-tac/ and place the card into the clay to create a “stand” for the card. Place the cards so that they stand vertically and at an equal distance from each other. See Diagram.
5. Place the flashlight at one end of the row of index cards and turn off the light in the room.
6. Arrange the cards so that light can be seen through all the holes.
7. Observe and record your observations.
1. How can light be seen through all the cards?
2. What would happen if the cards were not aligned?
3. What does the experiment prove about the path light travels?
4. What would happen if the holes were smaller?
Please write your plan out and ensure the conclusion questions are answered. Feel free to send photos of yourself conducting the experiment etc.
