These 28 colorful Stability and Change in Ecosystems science task cards are aligned to the new 6th grade Utah SEEd Standards. Topics include: ecosystem interactions among organisms including abiotic and biotic (12 cards), energy in an ecosystem - food chains (6 cards), stability of populations/ ecosystem services (8 cards), and invasive species (2 cards). This is part of a larger bundle that covers all the topics for the 6th grade SEEd Standards in Utah. These cards provide fantastic cooperative learning opportunities as students review for testing. A student work space is provided as well as an answer key. Students will likely need more space to answer questions, so they can use an additional sheet of paper. Copy, cut sheets into 4ths, spread around the classroom, and let kids play-learn while moving from card to card in any order. ENJOY!
