Goals:
to highlight important water-related themes and topics.
to inspire and encourage concrete actions that benefit the water resources
to celebrate the diversity and immeasurable value of the water
to increase awareness of nature resources, culture and history.
Collecting the Water Sample: If students are able to SAFELY reach the water body (within arms’ reach), then water temperature, pH, dissolved oxygen, and electrical conductivity measurements can be taken on site (in situ) directly at the water’s edge. However, the measurements of alkalinity, salinity, and nitrate require a sample to be taken with a bucket using the bucket sampling procedure. For electrical conductivity, if the temperature of the water sample is outside the range of 20-30˚C, then allow the sample to adjust to the temperature within that range before conducting the measurement.Calibration is a procedure to check the accuracy of testing equipment. For example, to ensure that the pH instruments are functioning properly, a solution of known value is tested. Calibration procedures vary among the measurements and are detailed in each protocol. Certain calibrations must be done in the field just before the measurement is taken. Other calibration procedures are done in the classroom.
Short description
One of the key success indicators of the Water Day is for us to be able to communicate about the water resources in a way that engages new audiences and gets people interested in healthy food and nutrition!

Challenges in implementation
A quality assurance and quality control (QA/QC) plan is necessary to ensure that test results are as accurate and precise as possible. Accuracy refers to how close a measurement is to its true value. Precision means the ability to obtain consistent results.
