Autumn has started with a bang. The nights have become noticeably cooler, and the days shorter. Trees are beginning to change color, and will soon begin shedding their leaves. For many plants, the lifespan of their hardworking leaves has come to an end; they will soon color, shrivel, and finally die. In some parts of the country, many plants will remain dormant for the winter, and only gradually re-animate in the spring, when they unfurl new leaves.
Leaves are indeed the workhorses of plants. Through the process of photosynthesis, leaves absorb carbon dioxide and sunlight, and convert the sun’s rays into energy in which to make food. Water, of course, is also necessary for photosynthesis to occur, and is absorbed through the plant’s roots. Once energy is created, the plant is able to store reserves in its leaves for future use, and emits oxygen as a waste product. It’s a remarkably efficient process, and vital to the survival of nearly all living things. Animals and humans exhale carbon dioxide, which the plants take in, and in turn emit oxygen for our use. Photosynthesis occurs in some bacteria, algae, and in most plants.
This week’s Joann’s Picks resources on photosynthesis are for a variety of grade levels, and some can be adapted for different ages. Joann’s column on the Gateway’s home page, www.TheGateway.org will feature three resources addressing photosynthesis. To complement the ideas and resources presented by Joann, this week's Peggy's Corner column will introduce several very special photosynthesis resources.
In addition, we will also be featuring many more lessons, activities, and resources on photosynthesis on the Gateway’s Facebook (http://www.facebook.com/TheGateway.org) and Twitter (http://twitter.com/Gatewaytoskills) pages. Follow us on Twitter and Like us on Facebook so you don’t miss anything. Discussions will continue on last week’s theme on both pages. All of the weekly Gateway columns and resource selections are archived on the following blog site: http://thegatewayto21stcenturyskills.blogspot.com/.

About the GLRC
The Global Learning Resource Connection (GLRC) is a public-private collaboration which brings to fruition ongoing work between JES & Co., a U.S. 501(c)(3) education research organization, corporate sponsors and education agencies worldwide. Leading the initial corporate involvement are founding worldwide partners Microsoft, Cisco, Cengage/Gale, the National Education Association (NEA), and other leading corporations in process. The GLRC ties together several significant semantic web technologies developed through funding from the National Science Foundation and is designed to support cyber learning. The GLRC supports the implementation of the mapping of major collections of learning resources in systems around the world to the machine-readable expressions of the learning outcomes based on the Achievement Standards Network (ASN) modeling and technical framework. The work will implement the international linking of those resources through trans-jurisdictional mapping of learning outcomes by means of Semantic Web/Linked Data principles for teacher/learner access and use.
