Square of Life: Studies in Local and Global Environments is an Internet-based collaborative project in which students will investigate their local environment and share that information with other students from around the country and the world.
My students participated in this project. It is great for hands-on learning and developing inquiry skills in science. Students plotted a square yard and recorded what they saw. We then uploaded that information to the website. Now that the data has been uploaded the students will compare and contrast their areas with other schools across the United States.
