In Biology, we’ve been learning about water. We learned that water is the universal solvent. A solvent is a liquid that a substance dissolves in. To prove this point we conducted an experiment. On lab day, we conducted our first one. We poured 10 mL of water into four different test tubes. Next, we added either sodium chloride (also known as table salt), sugar, baking soda, or epsom salts. We set a timer and after one minute, we saw how much the substance had dissolved by comparing it to a test tube that had the same amount of the substance in it.
All in for learning
