DAY 1

¨Divide students into groups of 5. 

¨Tell them to brainstorm for 10 minutes about the various ways water comes into their house or onto their property.  Tell them to have one person write it down.

¨Next, tell them to think about where all that water goes, and what has been added to the water in each place it is used for 15 minutes.

¨Bring the students back together and have a leader from each group get up and describe the ways water enters and leaves the house and yard and possible wastes added to it..

¨Tell them that for homework they should develop a list of the ways water enters and exits their own house and property.  Have them do diagrams if they need to for clarification.

DAY 2

¨Bring a quart jar, a tootsie roll, some rabbit pellets, liquid soap, some hair, food scraps, and a small bag of dirt.

¨Fill the jar half full of water.  One by one add each of the ingredients and stir, explaining what each represents as household wastes going down the drain every day.

¨Have random students get up and speak about what they found in their homes and in their observations.

DAY 1

¨Work in small groups to brainstorm the ways water flows into your house or onto your property.  Think about natural water flows as well as man made.  Have one group member act as a recorder to record this information.

¨Now describe where all that water goes and what has been put into it as waste.

¨Report on what your group came up with.

¨At home, make a list of all the water sources, and where the water actually goes, including the wastes added to it.  Write this down and make drawings or diagrams as needed to make it clear.

DAY 2

¨Observe the teacher's mixture of wastes that need to be removed in the wastewater treatment plant.

¨Report on your findings. Take notes of the findings of others that differ from yours.  Add any that you know exist but missed when you were checking at  home.
