Chemistry experiment

     

     My experiment includes:

• 2 (150ml) beakers
• 50ml water
• 50ml polluted water (Chemical changes in the water)
• Plants which grow in the water

     To make my experiment more accurately, I keep the weigh of the plants (I count the numbers of leaves), the same amount of water and the same size of beakers.

   

      The details are below:

         According to the list I wrote after observe, I found that the plant in Beaker 1 had more than the plant in Beaker 2, this shows that industrial water was threatened to the plants in the water. Let us image, if there are fishes, animals live in the water, they probably will die soon. So this shows that industrial water is harmful.

         Human being is living on the earth, the water, the air, the environment around us are all very important to us, we need to keep them clean, protect the earth, so that will be happy.

      Let's stop polluting the water, especially the factories and companies, the water is becoming more and more dirty, maybe one day there are no clean water for human being.

(This shows the alive leaves, from here I can see leaves in Beaker 1 is more than Beaker 2)
