Ecosystems LEARNING TARGETS: Date: Evidence: Date: Write a detailed laboratory report that includes: the question, hypotheses, materials, procedure including the use of computers, a summary of data in tables and graphs, and a conclusion, based on the collected evidence and scientific knowledge, that responds to the question. INQE 1.5 Demonstrate creativity and critical thinking to formulate and evaluate the hypotheses. INQG 2. Participate in a scientific discussion about your own investigations and those performed by others. Respond to questions and criticisms, and if appropriate, revise explanations based on these discussions. SYSB 3. Represent an ecosystem using a diagram understanding the trophic levels and energy flows. SYSC 4. Create a simplified model of an ecosystem. Trace the possible consequences of a change in one part of the ecosystem and explain how the simplified model may not reliably predict consequences. PS3A 5. Describe and calculate the energy transferred from one trophic level to another and explain how energy is conserved. INQA-D 1. Draw a systems diagram to illustrate and explain why introduced species often do poorly and have a tendency to die out, as well as why they sometimes do very well (Zebra Mussels) and force out native species. LS2D 6. Compare the biodiversity of organisms in different types of ecosystems (e.g.Turnbull aquatic sites) noting the interdependencies and interrelationships among the organisms in these different ecosystems. LS2E 7. Classify organisms, using similarities and differences in physical and functional characteristics. LS3E 8. Discussion Question: Discuss with your parents/guardians and write a one paragraph summary of the conversation in your notebook, and then have them write their initials next to the summary? Identify an ecosystem. Identify one change that has affected this ecosystem. What are three possible consequences to this ecosystem due to this change?
