Leanring new words

Today in Science, we learned four new words. We learned about Toxic, Sediment, Nutrient, and Bacterial pollution. Toxic pollutants are generally cinsidered to be a material that causes death, for example a battery acid. Sediments are consists of soil, sand and minerals washed from land into water usually after rain. Nutrient is the contamination of water resources by excessive amounts of water, like human waste. Bacterial is tiny microscopect living organisms that can make air pollution. After we learned all these we took a short 12 question quiz over these four words.
