Question 103
You will do experiments that will help you explain what you see when you pour the sugar or salt solution into water.
Work in groups.
You can use equipment such as:
• a ray box and power supply
• glass or plastic containers with smooth, flat sides
• water
• other transparent liquids
• sugar and salt to dissolve in water.
Safety
Remember to keep liquids away from the power supply and the ray box.
Carry out experiments using the method in Think like a scientist: Drawing accurate ray diagrams in Topic 6.2.
Investigate how each substance refracts light.
When you dissolve sugar or salt in water, does it change how the light is refracted?
