**2. Please write ONE complete Current Events note from any time during our last two weeks. EXAMPLE: The fires in California this season have consumed more timber than in any other fire season in California history.**

**3. Why is the Metric System (SI) easier to use for science than the Imperial System (feet. miles, pounds, etc) that's still used in the United states?**

**4. What atoms combine, and in what quantities, to make; (The first is given as an example.). **

** A. Water: A combination of two hydrogen atoms and one oxygen atom.**

** B. Carbon Dioxide:**

** C. Methane:**

** D. Oxygen gas that's released in PHOTOSYNTHESIS:**

**5. In our science notebooks we did a leaf rubbing. Name THREE of the things that you thought the leaf rubbing resembled.**

** A. Example answer given in class: It looked like a satellite picture of a river system.**

** B.**

** C.**

** D.**

**6. (From our reading.). Name FIVE (5) characteristics of living things.**

**7. (From our reading and our lab.). You've completed and experiment and you now graph the results on an X and Y axis. When you plot the data, you notice that the points on your graph do NOT make a straight line but, instead, are scattered randomly. What conclusions could you make about the relationship between your independent variable and the dependent variable?**
