Springâs warmer temperatures coax sugar maple trees to turn stored starch back into sugar. Sap is made as the tree mixes ground water with the sugar. The sap is mostly crystal clear water with about 2% sugar. It takes 40 gallons of sap to make each gallon of maple syrup which has a sugar content of 66.9%.A typical sugaring season lasts 4 to 6 weeks.he sap is mostly crystal clear water with about 2% sugar.

Oxygen is the third most abundant element in the Universe today, and in the very, very far future, may even have the opportunity to rise further as hydrogen (and then possibly helium) falls from its perch.
There are several known allotropes of oxygen. The most familiar is molecular oxygen (O 2), present at significant levels in Earth's atmosphere and also known as dioxygen or triplet oxygen.Another is the highly reactive ozone (O 3). Others include: 1  Atomic oxygen (O 1, a free radical).2  Singlet oxygen (O 2 *), either of two metastable states of molecular oxygen.ee also: Dioxygen in biological reactions. The common allotrope of elemental oxygen on Earth, O 2, is generally known as oxygen, but may be called dioxygen or molecular oxygen to distinguish it from the element itself.
