"Reading the Story-Reflection" We read the third chapter of the story, which focused on industrial waste and water pollution. This was followed by a discussion, and the students illustrated the solutions they suggest for reducing water pollution.

Then, they poured dirty water and observed how the homemade filter trapped the debris and dirt, resulting in cleaner water. "Mathematics" First, the students measured the height of the dirty water using a ruler and recorded the number.
