This resource is for the 5th grade NGSS Performance Expectation: 5-ESS1-2 Represent data in graphical displays to reveal patterns of daily changes in day and night. These resources should take about 3 class periods to complete.
In this performance expectation, students will complete a 5E lesson cycle. They will graph data about the average length of days by month in the Northern Hemisphere to discover patterns. Students then read a text to gain the scientific knowledge of why this happens. They will elaborate by graphing data for a city in the Southern Hemisphere and another on the equator, and then apply their knowledge in the exit ticket.
There is a supplemental video to show the scientific concepts visually that are covered in the lesson.
Although these points are reviewed in the lesson, students should already know the following information before this lesson:
- The earth orbits the Sun.
- The earth rotates on its axis, and this causes day and night to occur.
- The earth can be divided in half by the equator, which creates two half spheres, called the Northern Hemisphere and the Southern Hemisphere.
