Every week, our class has one science lab lesson, where we visit the science lab to conduct various experiments. The experiments were very helpful in our learning, as we got to understand more about what we learn. Such experiments we conducted was on chemistry. My favourites was when had experiments on acid reactions. For example, what happens when acid reactions with carbonate.
Acid+Metal-->Salt+Hydrogen
Eg.Hydrochloric Acid+Iron-->Iron(||)Chloride+Hydrogen
Acid+Carbonate-->Salt+Water+Carbon Dioxide
Eg.Sodium Carbonate+Nitric Acid-->Sodium Nitrate+Water+Carbon Dioxide
Acid+Bases-->Salt+Water
Eg.Nitric Acid+Potassium Hydroxide-->Potassium Nitrate+Water
From the experiment, I also found out that some common salts were nitrates, sulfate, and chloride. And that common acids were hydrochloric acid, nitric acid, and sulfuric acid. We also found out about the application of these acids. We could conduct the experiments ourself, and thus develop a greater understanding on it, rather than listening to the teacher explain.
Thus, I feel that Science Lab lessons are very meaningful and helpful.
