## Pollution Chemical industries through the process of production pollute our environment. Chemicals enter the soil and air by different ways like the products are made by using a lot of chemical lovers and specifically the chemical lovers have placed pressure on our environment and acid rain have increased pollution. Lead from motors vehicles and acid rain have made our annual life an endangered plant. ## Scientific Method This is the method the scientist used to discover materials. They use different methods of chemistry. The following steps and stages are followed: * Observation * Pattern * Problem * Hypothesis * Experiments * Theory * Law In the light of this, the scientists use their lenses to observe what is happening around them from a given set of observations they see a certain pattern. This often leads to a problem which they try to solve. They put theories and reasons to test it. Then they carefully record their experiments to test it. Then they carefully record. ## Laboratory Tools 11. Dropper: * It’s used in keeping solutions or reagents hot in drops during experiments. 12. Spatula: It’s made of metal and looks like a spoon. It is used to transfer a small amount of solid powder, granules etc.
