Hands-On Water Analysis ActivityActivity by Stephen Twa | added on Feb 26, 2011 | Canada
Sponsor(s): Edmonton Science Outreach Network (ESON) and the Northern Alberta insitute of Technology (NAIT)
Visiting chemists come into Gr. 4-6 classrooms in the Edmonton region and give a presentation on basic water testing. Under the guidance of these chemists, the students test their own water samples.
Hands-On Water Analysis Activity
For: Grade 4 – 6 classes (Edmonton local area)
What: A free 1 to 1 and a half hour classroom presentation and activity involving basic water testing
Who: Local Edmonton chemists
When: Jan. – Dec. 2011
How: Book through the Edmonton Science Outreach Network www.sciencehotline.ca
Select the Teacher’s Tab and make a booking under Classroom Presentation
Students will listen to a presentation on basic water testing and will then, under the guidance of the visiting chemists, analyze their own water samples. The tests performed include: turbidity, pH, dissolved oxygen and conductivity.
For turbidity, students will use Secchi disks, a turbidity tube and/or a turbidity meter.
For pH, students will use pH paper, universal indicator and/or a pH meter.
For dissolved oxygen, students will use chemicals in blister packages and vials.
For conductivity, students will use a conductivity meter.
The main point of the activity is to help students understand the importance of good quality water supplies and how to monitor that quality through some simple tests. The hands-on format is designed to excite the students and to show them that they too can do some of these simple tests.
