Examples of some of the most common deciduous trees are oak, maple, beech and sycamore. Deciduous trees are trees that shed their leaves annually.Continue Reading
Deciduous trees belong to the flowering plant group, angiosperms, and they are also called leaf trees, broad-leaved trees or foliage trees. There are more types of deciduous trees than there are conifers, or evergreens, which do not shed their leaves on an annual basis. In most North American latitudes, deciduous trees shed their leaves in autumn to avoid becoming parched during winter.
The most common method of tree identification is by noting the shapes of the leaves, which are typically oval, narrowly oval with a pointed tip (lanceolate), triangular, round or heart-shaped. The edges of the leaves are important identifiers too. For instance, apple, birch and aspen trees have dentate (tooth-like) edges, while beech tree leaves are serrated and oak leaves have lobed edges.
Besides leaves, deciduous trees also can be identified through their buds, bark, blossoms and fruit. During winter, when the trees have shed their leaves, identification is usually made through bark characteristics. White poplars and birch trees are readily recognizable by their light grayish bark that sometimes appears flaky.
When deciduous trees are in bloom, their fruits can make identification easier, as in the case of apple, pear or cherry trees. Nut trees are also deciduous (beechnut and acorn, for instance), as are trees with air-borne fruit and with wing-shaped seeds, such as maple and ash.Learn more about Science
Examples of completely safe electrical science projects for kids include rubbing a balloon against the head until it causes hair to stand up (a result of static electricity, which is harmless) or using a Squishy Circuits Kit to make play dough that can be used to build a simple circuit; the latter can then be used to drive a motor or light an LED. Anything requiring the building of a circuit should always be supervised by an adult, although the balloon experiment is both safe and easy to demonstrate.Full Answer >
Beech trees that seem to have a white, fuzzy texture are likely infested with the beech blight aphid. This is a small insect with a white, fluffy body that may give the tree's branches and leaves the appearance of having a light, wooly texture. Though this aphid may appear on any part of the tree, they tend to appear mostly on the tree's branches because they drink the tree's sap rather than feeding off the leaves.Full Answer >
The Penquis Virtual Nature Center provides a list of hardwood trees that includes species of alder, poplar, birch, beech, oak, cherry, sumac, maple and ash. Each tree species has its own distinct characteristics, but all of them are classified as hardwood because of some distinguishing features.Full Answer >
Examples of eighth-grade science projects include determining if tea and coffee stains teeth and examining the principles of flight using kites. Many eight grade students also complete a science project that requires the student to create a levitating orb.Full Answer >
