Science week of 10/12/09

This week in science was very interesting because we were studying for the test on Monday. We had to complete a study guide. We went over wave models and dense and less dence objects.When the wave front has more spread out lines which means that is less dense. If the wave front lines are closer together, then and object is more dense. We also went over Refraction Reflection,and of course, overall light. Since our test was on Monday, we were going over literally everything we have learned ever since the light unit started. Mr. Finley also had to study sessions on Thursday and Friday.
