List of Materials Needed:
 Field guide notebooks with retention rate problem sheet and writing utensils (see
Appendix A)
 Measuring device (Trundle wheel)

Activity Time Frame:
 2-3 hours

Environmental Setting:
 Water treatment facility (measurable tanks)

PASS Objectives:

   Geometry IIB - Use properties of 2- and 3-dimensional figures to determine
unknown values (e.g., given the perimeter/circumference, find the area).

   Geometry IIC - Compute length, perimeter/circumference, area, volume, and
surface area of geometric objects with missing information and correctly identify
the appropriate unit of measure of each.

   Process Skill 9-12 IB - Identify the problem from a described situation, determine
the necessary data and apply appropriate problem-solving strategies.

   Process Skill 9-12 IIIA - Use various types of logical reasoning in mathematical
contexts and real-world situations.

Project Objectives:
Students will:
 Identify how math can be used in everyday life through studying volumes, flow
rates, and performing calculations at a water treatment facility
 Compute the volume of three dimensional shapes
 Use creative thinking to create a formula for solving solve retention rate problems
 Work in groups to calculate retention rates
 Create a presentation top show peers how water gets brought to the facility,
treated, and delivered to the community

Vocabulary Terms:
 Flow rate
 Volume
 Retention rate
 Retention Tank
 Sludge Pond

2
Background Knowledge:
 Knowledge of how to compute volumes

Activity Procedures:
 At the plant the tour guide will discuss:
1. Steps taken in the treatment of water
2. Geometric properties of the holding tanks (cylinder, cone, cube)
 Students take notes in their field notebooks during tour about the properties of
each tank (see Appendix A)
 Divide into groups of 4-5 students and assign them a specific tank to measure
 Have students measure and record dimensions of given tanks to be used to
calculate volume
 Students will use collected data from field notebook to answer worksheet
problems (see Appendix A for worksheets) (each worksheet corresponds to a
specific tank assigned, each group only answers their assigned tank questions)
 Have students use field notebooks to derive flow rate formulas for their assigned
tank given in worksheet
 Students will present their findings to their peers using Microsoft Power Point

Possible Extension:
 Classroom excursion to the nearest water tower as an exercise in volume finding
(contact city for dimensions)
 Find the water pressure associated with the different water tower heights (one
cubic foot of water weighs 62.4 lbs, 2.31 feet equals one pound per square inch of
pressure)

Technology Components:
 Student prepared Power Point presentations on steps for treating water

Assessment Tools:
 Field notebooks (Appendix A)
 Pre/post tests (Appendix B)
 Presentation rubric (Appendix C)

Appendix A: Field Notebook

Water Facts:
In the lines provided below, list some of the things that happen to water as it comes to the
people of Norman, for example: Where does the water come from? What happens to the
water at the Water Treatment Plant? How does the water get to the people of Norman?

Volume =

Average retention time can be defined as the time it takes for the water to
circulate through the tank and get cleaned in the process.

Think about the things you would need to know in order to calculate the retention time
for the shape above. List them below.

How much water can the tank hold at one time?

5
With a flow rate of 4ft3 per second, how much time would it take to fill up the tank?

If you have a city of 100,000 people and each person uses 15 gallons of water per day,
and the treatment tank is 1,000,000 gallons, what flow fate has to be maintained to ensure
there is enough treated water for everyone?
