We set out with 15 taps, drill, hammer, milk jugs and a bit of moxie. Each time we put in a tap the children would line up and let the sap drip right into their mouths. It was fun for all of us. In the end we made about 4 or 5 gallons of syrup. We had an ice cream party, we had a pancake party and we gave almost all of the syrup away. I gave myself a pat on the back and started thinking about how this could be better.
This year we started earlier and put in 25 taps, bought collecting pails with lids and planned better. Within the first three days I burned through too many propane tanks, too expensive. I looked online to get ideas and hoped I could find a better way. I found a photo that someone had taken of their home made evaporator made out of a 55 gallon drum. I asked around and found a member of the school community that eagerly took on the project. It took him three days to complete. We now have an evaporator! Thanks Bryce. The kids immediately started calling it the giraffe, see the pictures below and you will understand. I planned better this year. The children worked on activities that supported tree identification, they learned about the boiling point of water and evaporation. They learned that it takes about 40 gallons of sap to make 1 gallon of syrup, they learned about liquid conversions and we read various myths and legends about the first people to tap trees. The class wrote instruction manuals and illustrated stories. They learned about fire safety, we carried truck loads of wood and learned how to read a thermometer. They realized that a five gallon bucket full of sap is heavy! We kept graphs in order to keep track of "gallons collected and syrup made." But most of all they wanted to know, "when are we having our pancake party?" Who can blame them? We are writing invitations so that others can enjoy our sweet and sticky bounty.
When you walk out onto the Lower School playground the sandbox has been transformed. The "giraffe evaporator" is in the center surrounded by pots, fire proof gloves, an ax, boiling pots of sap and the thermometer. The children are invited over a few at a time to do various tasks. Yes, they load the stove, check the temperature and strain the sap. So far we have made one and a half gallons of syrup. Along the driveway there are 25 more gallons of sap waiting to be boiled and the collecting buckets were nearly full when I left campus today. When it is all done I am hoping to write an in-depth article for some publication but for now this is what is happening in my classroom.
The class made the sandbox too. 3 years ago.
