Measuring Rainfall under Collaboration

... happy to be part of School Environmental Collaboration and this time - activity on water ...

I have been in SEC project with full enthusiasm and equally feeling something is lacking in non-participating teachers and schools that were selected after the review of the applications.

Installing Rain Gauge at School

I have been in touch with Mr. Yubaraj Adhikari, Principal of Durga Bhawani Adarsha Community Lower Secondary School (DACS), Kaski, not only for this project but also for further NTNSE projects and developments. We decided to perform this project upon collaboration.

We asked our pupils to collect some PET mineral water bottles (1 Liter.) of standard size of Nepal. We told them that rainfall of 2 parts of Nepal (Thapagaon, Mid Baneshwor, Kathmandu and Serachour, Dhikurpokhari-9, Kaski) is being measured by making standard and easy-to-make 'rain gauge'. We asked them to cut the cone shape (funnel) of the bottle till the first groove and invert it over the bottle's another part so that water can be collected by the cut-piece-funnel into the next piece-container and use tape to fix the funnel in the container (both pieces of PET bottle). Our pupils at Chelsea International Academy did so and brought 5 samples.

Doing some Calculation

We helped pupils to keep the apparatus in open place, safe for 48 hours (10:15, 22nd July 2013 - 10:15, 24th July 2013). We measured the rainfall by pouring the collected water into the measuring cylinder and calculated the average.

We measured 122.66 ml in our school and Mr Adhikari sent me SMS from DACS; their result was 55.33 ml. We are looking forward to see blog post from Mr Adhikari.
