DOES ADDING SALT TO WATER EFFECT THE ANGLE OF REFRACTION?

Hypothesis:
A salt water solution will have a greater angle of refraction than tap water?

DATA

Untitled Slide

Salt water solution

Tap water

Conclusion:
The salt water solution does not have a greater angle of refraction than tap water.

NEXT STEPS

• I would use a more exact, reliable form of measurement
• Vary the amounts of salt in the solution
• Try other solutions
