Ventilated storage structures for onions
Ventilated storage for onions or garlic (cost of contruction is Rs 30,000 = US$600; capacity = 6 MT)
Onion Storage Structure. Specifications are already in use for DASPII Project and are well known, and has been shown to be cost effective in India. Losses are reduced from 60% to 10% or less, over a storage period of 4 to 5 months. (10 x 15 x 15ft high –with two levels).

An inquiry into lighthouses
We began our inquiry by looking at maps and photos of lighthouses around the world.
In the past week, we have listened to a CD of “lighthouse sounds” while we sketched images and wrote words, sentences or poems that came to our minds. We took tours of lighthouses on the internet, and we even managed to find a site that shows a live webcam of the Peggy’s Cove lighthouse, so you can see what’s happening there all day long. We have had it on the SMARTboard every day, all day, and many of the children have been watching it at night at home too. Last week, I led them through a guided meditation where they visited a lighthouse in their minds. We’ve read stories about lighthouses, some fictional and others non-fiction. We also read stories about hurricanes and storms that destroyed ships and even lives. Many of the children had questions about light keepers and became very curious about this role, which we researched together. Last week, we learned that the Peggy’s Cove lighthouse is 15m tall, which seemed like a very abstract measurement to the children, so we went outside and measured a 15m lighthouse on the grass using meter sticks. It turned out to be a wonderful chance to develop some estimation skills in the sunshine. This math led into a rich discussion around the sizes and shapes of lighthouses (one child thought that if the lighthouse is 15m tall it must be 15m wide and another student suggested that that would make it a square lighthouse, which led into a lovely discussion around shapes). After, the children played in our pretend lighthouse on the grass, imagining they were lighthouse keepers saving sailors from storms on the ocean.
Yesterday, the children decided to construct a big lighthouse in our classroom, which has created many problem solving based conversations about 3D shapes, good building materials, making democratic decisions around who will do what, etc.
I think that next week we will begin the important work of discussing the uncertain future of the Peggy’s Cove lighthouse. I can already see the passion in their eyes about this lighthouse, so I can only imagine their reaction to the possibility of this lighthouse being demolished and where this discussion will lead.
Its been a lovely inquiry so far!
