Exploring Water Quality in Biology and Chemistry Classes
In a biology class, students examined water from the Niauduva River and found it relatively clean with few organisms present. In a chemistry experiment, a test was conducted on water from both the river and a sink. The water from the river was determined to be clean after testing with PO4 indicator. The engaging activities provided valuable insights into water quality assessment techniques.

Presentation Transcript
Biology The teacher gave us water from the Niauduva River and we inspected it if it is clean or dirty.
Actions 1. Took some water from the river 2. Put it on a special glass 3. We put it on the microscope 4. Saw some small organisms
Result Not many organisms Water is quite clean
Chemistry The teacher gave us water from the sink and the water from the Niauduva River.
Actions 1. Put some water from the river to test tube 2. Added some PO4 3. Took indicator 4. Put in water
Result Water from the river is clean
Thank you for attention
