The saving grace of the change to Daylight Saving Time is that it coincides with one of my favorite things about spring, maple syrup season! That means days are getting a little longer and the sun is a little higher in the sky during the day. As a result of that increased daylight and warmth the sap in maple trees is starting to run. Some of my local friends make their own maple syrup and have started to collect sap to make syrup. 
The process of collecting sap and turning it into maple syrup provides some great science lessons for students. The process of creating maple syrup can teach students lessons about why maple sap is easiest to collect in late winter/early spring, what makes the sap run, and it teaches students about evaporation. 

Here are a few video lessons about making maple syrup: 

Ever Wonder How Maple Syrup is Made? is a video from Highlights. The succinct video shows a mix of the old way of using buckets to collect sap and the modern method of using hoses.

My friend Gardner Waldeier AKA 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 he 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.

Maple Syrup the Modern Way is a three minute video about the process commercial producers use to make syrup.
