The main idea of these lessons is to gather empirical evidence that shatters the misconception many people hold that when we are closer to the Sun it is summer and when we are farther away from the Sun it is winter. NGSS and Math Common Core Standards integrate to help students reach the accurate conclusion. For example, students use proportional reasoning to create scale models. The Common Core Math Standards used in these lessons are: CCSS.MATH.CONTENT.4.MD.C.6
The lesson plans follow the 5 E model and should take about 8 class periods. More information about the lesson can be found at www.scienceteachermama.com.
