I.O./SWABT 1. Express knowledge of vocabulary 2. View videos of water water plant design 3. Make or begin to grasp ideas in desing4. explain various parts of waste water system using appropriate vocab

PROCESS STANDARDS:http://www.emsc.nysed.gov/ciai/mst/sciencestand/physset13.htmlNew York State Learning Standards:The following are addressed in this lesson.

Standard 1: Analysis, Inquiry and DesignMathematical AnalysisStudents will use mathematical analysis, scientific inquiry, and engineering design, as appropriate, to pose questions, seek answers, and develop solutions.

Standard 4: ScienceStudents will understand and apply scientific concepts, principles, and theories pertaining to physical setting and physics.

Standard 6: Interconnectedness: Common Themes

Students will understand the relationships and common themes that connect mathematics, and science, and apply the themes to these and other areas of learning.

WHAT IS WASTEWATER?

Wastewater is liquid waste. It is animal, vegetable, mineral or chemical matter in solution or in suspension that residents and businesses flush down their toilets and pour down their sinks and drains.

Wastewater drains into a network of pipes maintained by sewer serviced municipalities and the Regional District of Nanaimo. Sewer systems are built to follow the natural slope of land, generally flowing towards the sea front. This design allows gravity to do most of the work transporting the wastewater to one of four wastewater treatment plants. For residential areas that are lower than adjacent lands or treatment plants, the wastewater must pass through a pumping station to pump the liquid into the plants. Treatment of our wastewater is an essential process that prevents contamination and destruction of our waterways, and our natural water resources.

HOW IS WASTEWATER TREATED IN THE RDN?

Goto power point then handouts from

Procedure:

Wastewater Presentations

Give your students the opportunity to learn about the components of a wastewater collection and treatment system by using an interactive Enviroscape model. The wastewater Enviroscape model is a hands-on learning tool that demonstrates what happens to water after we use it (how sewage/wastewater is treated). Teachers may choose from one of two options:

1) You may borrow the model and teach the lesson. All the supplies you need to teach the lesson will be included with the model, along with a User’s Guide. The User’s Guide

provides step-by-step instructions for set-up, teaching the lesson and clean-up. You must return the model, guide and supplies to SD1 within one week of check out.

2) You may schedule a representative from SD1 to teach the lesson using the Enviroscape model.

a 10-minute video on the wastewater treatment facilitate Q & A and provide other wastewater education resources by request.

**The wastewater Enviroscape model is also designed to teach students about the process of treating drinking water and the use of biosolids. You may teach this portion of the lesson by following the instructions in the User Guide. However, SD1 only offers to teach the wastewater portion of the lesson.

Students will hand in the below handout
