Unit 2 Project: Matter100 points

Instructions: Complete Steps 1 and 2. You may either neatly hand write or type your project. Your project should have a title and four paragraphs, each paragraph addressing one change and the questions below from either Digestion or the Water Cycle. A picture (hand drawn or computer image) should accompany each paragraph (on the right or left side) demonstrating the change you are addressing.

  1. Choose either Digestion or the Water Cycle.
  2. For your selected process, identify:
  3. 50 points: Two chemical changes that occur during this process. For EACH chemical change, answer the following questions in paragraph form:
  4. What is the chemical change taking place?
  5. What signs show that a chemical change is taking place?
  6. What is the result of the chemical change? A compound? A mixture? How do you know?
  7. Is the resultant substance heterogeneous or homogeneous? How do you know?
  8. 50 points: Two physical changes that occur during this process. For EACH physical change, answer the following questions in paragraph form:

i. What is the physical change taking place?

ii. What signs show that a physical change is taking place?

iii. What is the state(s) of the matter before the physical change? What is the state(s) of matter after the physical change?

iv. Is a phase change occurring during this physical change? If so, what is the name of the phase change and is the phase change exo or endothermic? How do you know?
