Overview of biodiversity and extinction.
Patterns and processes of evolution. How evolution and natural selection are reflected in the similarities and differences of organisms.
Bring the rainforest to life in your classroom! Give your students hands-on experiences that will build their understanding of the importance of tropical rainforests and the need for protecting these valuable ecosystems. Explore topics including the water cycle in the Amazon, the life cycle of rainforest plants, rainforest conservation challenges, and more. You can use this kit to prepare your students for a field trip to the Academy's Rainforest Exhibit. Or, if you can't make it to the Academy, use the kit on its own to bring the rainforest to you! This version of the rainforest kit is for grades 4 - 8.
Students will learn that there is a finite amount of carbon on earth, which moves around in the environment, from one place to another. Activity is scaleable from elementary to high school with options to introduce advanced content. Wrap up includes role playing the carbon cycle with the addition of human influences (e.g. burning of fossil fuels). Activity can be done in classroom or outside, includes working in a group and role playing. Grades 3-12. This resources is part of the Our Changing Ocean and Estuaries Series

How genetic variation is the raw material of evolution, and how restricted gene flow can lead to the formation of new species.
In this activity, students will practice the steps involved in a scientific investigation as they learn why ice formations on land (and not those on water) will cause a rise in sea level upon melting. This is a discovery lesson on ice and water density and displacement of water.
