<p> 8 th Grade Science Fall Project Rubric</p><p>September 30, 2016</p><p>Students need to create a model using a variety of fall leaves to showcase the effects of photosynthesis on different types of trees. Any combination of trees may be chosen, as long as there are at least 4 different kinds. Models may be physical, conceptual, or mathematical in nature. *Bear in mind that regardless of the type of model chosen, samples of leaves must be provided or referenced.</p><p>Example: Physical Model – 1 maple leaf 1 birch leaf 1 elm leaf 1`oak leaf</p><p>Example: Conceptual Model – Images of changes experienced in autumn by: 1 maple leaf 1 birch leaf 1 elm leaf 1` oak leaf</p><p>Example: Mathematical Model – Scaling the effects of photosynthesis in autumn on: 1 maple leaf 1 birch leaf 1 elm leaf 1` oak leaf 1. Leaf type must be accurately represented (correct tree type). </p><p>2. All leaves chosen must begin as green.</p><p>3. An explanation must be provided as to:</p><p> a. Why the leaf changes color in autumn</p><p> b. Why each leaf changes to its particular color in autumn (Birch leaves turn yellow – why?) Explanations must be accurate.</p><p>4. Project must be presented in class. Students should be able to answer questions about their project and why their specific model type (physical, conceptual, or mathematical) was chosen.</p><p>5. References should be cited (Where did you get your information (including images))?</p><p>6. Project must be turned in by the due date (October 27, 2016). 5 points will be deducted for every school day the project is late.</p><p>Grade Scale:</p><p> 6 of 6 items listed above are incorporated into the final project = A+</p><p> 5 of 6 items listed above are incorporated into the final project = A</p><p> 4 of 6 items listed above are incorporated into the final project = B – B+ </p><p> 3 of 6 items listed above are incorporated into the final project = C – C+</p><p> 2 of 6 items listed above are incorporated into the final project = D+</p><p> 1 of 6 items listed above are incorporated into the final project = D</p><p> 0 of 6 items listed above are incorporated into the final project or project is not completed = F</p>
