Leaf Decomposition – Making Tea
When leaves enter streams or other bodies of water, leaf compounds are removed from the leaf and enter the stream. Streams where leaching caused the water to be a dark color are referred to as black water streams. In this lab students will observe the results from leaching. Students will compare the difference in water color between two leaf types.
1. Define leaching
2. Explain what is a black water stream
