Bus Huxley on YouTube collects maple sap to make maple syrup. He does it the old fashioned way and he made a video about the process.
Gardner's video shows viewers how he collects maple sap and turns it into maple syrup. In the video explains why maple sap is collected at this time of year, how much sap he'll collect from a large tree, and just how much sap it takes to make a gallon of maple syrup. You also get a nice tour of Gardner's woodlot and plenty of images of his helpful dog.
Applications for Education
I don't think that Gardner deliberately edited the video to have the ideal length and pacing for a flipped classroom lesson, but that's how it turned out. Try EDpuzzle or Vizia to make a flipped lesson with Making Maple Syrup by Bus Huxley.
