This document outlines an experiment to test how temperature affects the solubility of salt and sand in water. It provides hypotheses that salt will dissolve in water, and dissolve more easily in hot water, while sand will not dissolve. The experiment uses four glasses, hot and cold water, salt, sand, and a spoon. It involves adding salt and sand to the hot and cold water and observing whether they dissolve, then drawing a conclusion about how temperature affects solubility.

1. DISSOLVE IN WATER
EXPERIMENT

2. 1.- Can salt or sand be dissolved in
water?
2.- How does temperature affects
solubility?
Question 1 and 2

3. Hypothesis (Choose one of each)
• 1.- Salt dissolves in water/Doesn’t dissolve in
water.
• 2.- Salt dissolves easier in hot/cold water.
• 3.- Sand dissolves in water/doesn’t dissolve in
water.
• 4.- Sand dissolves easier in hot/cold water

4. MATERIALS
•Four plastic glasses.
•Hot and cold Water.
•Salt
•Sand.
•A spoon to stir.

5. PROCEDURE
•1.- Put salt in hot water and stir.
•2.- Put sand in hot water and stir
•3.- Put salt in cold water and stir.
•4.- Put sand in cold water and stir.

6. OBSERVATION
• Are there any salt in the bottom of the cold water glass?
• Are there any salt in the bottom of the hot water glass?
• Are there any sand in the bottom of the cold water glass?
• Are there any sand in the bottom of the hot water glass?
• Which one was easier to dissolve?

7. CONCLUSION
• The solubility of a substance increases as
the temperature increases.
• Sand can’t be dissolved in water because
it is insoluble.
