Making Maple Syrup
The origins of this breakfast staple may surprise you!

Whether you prefer pancakes, French toast, or waffles, they all pair perfectly with maple syrup! But before bottles of the golden liquid hit grocery store shelves, it starts out as sap from deep inside a tree. “Most syrup comes from the sap of the sugar maple tree because it is naturally sweeter than that of other species,” says Meg Emmons. She works on Bourdon Maple Farm in Vermont, which has more than 10,000 maple trees.
In late winter, warming weather causes sap to move toward trees’ branches in anticipation of the growing season. The sap flows best in temperatures that are below freezing at night but warmer in the day. In Vermont, that usually starts in early March.
Making maple syrup is hard work (see From Sap to Syrup, below). It takes about 40 gallons of sap to create just 1 gallon of syrup. Still, Emmons says the work is very rewarding—especially when it’s tasting time! “My favorite is having maple syrup on ice cream or with fried chicken and waffles,” she says.

Tapping:
This is the process of collecting tree sap. First, Meg Emmons drills a hole into the trunk. Then she inserts a spout connected to a network of plastic tubing on a vacuum system.

Evaporating:
As the sap drips from the tree, it is pulled through the tubes to a building called the sugar house. Inside, Emmons boils the sap in a large evaporator to remove the excess water.

Refining:
Removing the water concentrates the sugar, giving it a sweeter taste and thicker consistency. The high temperatures also cause it to turn a golden color.

Bottling:
Once it reaches the correct thickness, the syrup is filtered to remove any impurities. From there, it’s pumped into barrels and then bottled to sell!
Calculate the volume of different syrup containers. Use 3.14 for pi (π) and round answers to the nearest hundredth. Record your work and answers on our answer sheet.
If you make your own syrup at home, you can keep it in a Mason jar. The cylindrical jar has a height of 5.2 inches and a radius of 1.6 in. What is its volume?
Some maple farms sell their syrup in rectangular tins. One is 10.5 in. high, 7.25 in. long, and 2.25 in. wide. What’s its volume?
A cone-shaped syrup dispenser at your local diner has a height of 4.3 in. and a radius of 1.4 in. What’s its volume?
A. The largest jug you can buy at Bourdon Maple Farm is a cylindrical container with a height of 12.2 in. and a radius of 5.1 in. They also sell a smaller cylindrical jug with a height of 3.3 in. and a radius of 0.9 in. What’s the volume of each container?
B. How many of the smaller containers do you need to buy to have more syrup than the larger container holds?
How many of the smaller containers do you need to buy to have more syrup than the larger container holds?
On a separate sheet of paper, design a maple syrup container. Be sure to include its dimensions and find its volume!
