Grade 6 Science Experiment 1 - "What Happens to Chlorine during Water Filtration?"
The purpose of this science fair project is to determine if chlorine exists in our local rivers and lakes. Why would chlorine be in local rivers and lakes? Chlorine is a chemical substance used to purify water. Chlorine is also used to purify wastewater from water sewage treatment plants. Water is placed into local rivers and lakes after it has gone through the water filtration process at the water treatment plant. In an ideal situation, the water that is released into the local rivers and lakes is free of chlorine or contains trace amounts. However, this is not always the case. During this science fair project we will take samples of local rivers and lakes and measure the amount of chlorine in the samples.
Note: This science fair project requires adult supervision. This science fair project works best when you have a partner to help you complete the chlorine tests.
The chlorine level will be higher at locations closer to the water treatment plant.
- Six glass jars that have lids.
- Rubber gloves
- A chlorine test kit that is used to check the chlorine levels in pools.
