Students will have a 15-20 question test tomorrow. The test will cover the vocabulary words which are in their ISN Pages 3B and 4B. The concepts we have covered are: Why a decision matrix is used, Why constraints and criteria are important aspects of making a decision, What a system model is and what needs to be included in a system model. Students should have this material in their Interactive Science Notebook. Students can also review by working through the quizlet I placed on the blog last week.
