Our First Science Unit: Earth's Systems and Human Activity

Last year, students learned about the systems on our earth.  The unit will start with a review of those systems: geosphere, hydrosphere, atmosphere, biosphere and lithosphere.  These systems interact with each other all the time.  Our focus this year, will be understanding human impact on these systems.  We have changed the world by using its resources. We have taken responsibility by studying the changes and organizing people to come together, as communities, to use science ideas to lessen the impact.
