Slideshow transcript
Slide 1:Educational Objective Students will understand how latitude and season affect duration of insolation.
Slide 2: Purpose The purpose of this long term investigation is for 8th grade science students to use the internet to collect and organize latitude, date and duration of insolation data to help generalize the relationship between latitude, season and duration of insolation.
Slide 3: Procedure Google Earth will be used to identify locations with similar longitude and widely different latitudes. Students will then use internet resources to find and record sunrise and sunset times for each location during 4 seasons. A minimum of 2 class periods in the lab is required.
Slide 4: Procedure Students will then analyze their collected data to generalize how duration of insolation changes with changing latitude and season. Students will work in their assigned PBL group
