1 Life Science Curriculum Sixth Grade The Sixth Grade life science curriculum emphasizes a more complex understanding of cycles, patterns and relationships in the living world. Students build on basic principles through more complex processes of the living world. Emphasis is given to classification of living organisms and the processes that the organism employs to survive. The study of genetic principles and chemical processes is included for a better understanding of the nature of life and relationships between the living and nonliving world. I.

Develop questions and make predictions using patterns from data collected 3. Make inferences and draw conclusions about familiar objects and events 4. Develop a method to test the validity of predictions and inferences 5. Conduct experiments in order to answer questions 6. State the hypothesis in a way that identifies the independent and dependent variables 7. Manipulate one variable over time using repeated trials 8. Design models and create simulations to illustrate and explain phenomena and systems 9. Scale models are used to estimate distance, volume, and quantity B. Observations 1. Repeat observations to ensure accuracy 2. Describe experimental outcomes both pictorially and verbally C. Data 1. Collect and record data using proper graphical representations 2.
