Fourth graders at Cockrell Elementary celebrated Earth Day last week by making an online poster about all of the ways they could help the earth. The students used a program called Glogster, which allows the students to create a poster with text, graphics and even video. Doing all of this work digitally instead of on paper was a great example of how to save our resources. The first Earth Day was organized on April 22, 1970 and about 20 million Americans participated. According to the group’s website: "The passage of the landmark Clean Air Act, Clean Water Act, Endangered Species Act and many other groundbreaking environmental laws soon followed. Growing out of the first Earth Day, Earth Day Network (EDN) works with over 22,000 partners in 192 countries to broaden, diversify and mobilize the environmental movement. More than 1 billion people now participate in Earth Day activities each year, making it the largest civic observance in the world."
