NAH- This lesson lets students gain a more comprehensive understanding of oil spills through hands on activities. They see how the oil interacts with water, how it affects the ocean, etc. This allows them to physically see how humans impact ocean systems.
This little observation activity is great for lower elementary students. They compare water with and without trash in it. Children get up close and personal with how abandoned trash can pollute our water.
NGSS Aligned: Water Conservation Lab: Students Design and Carry Out a Study
This site shows great science experiments to show students how important conservation is. Although turning off water while brushing your teeth isn't going to solve the global water crisis, but it will bring it down to younger students level.
Possible school experiment to show importance of wetlands/riparian zones! This shows the importance of plants in our soil. Plants like trees and grasses help purify ground water. Without them the ground water gets polluted and harder to clean and drink.
Water is a vital substance not just for living organisms but also in the manufacture and processing of nearly everything. Therefore oil rides on the back of water, and fresh water is dwindling. Why Water is the New Oil
