Students are first introduced to the concept of latitude and longitude. Students' prior knowledge is assessed via a relatable entrance ticket. Polaris (the North Star) is identified as an important resource for determining latitude of one's location. Examples are used to allow students to practice with latitude and longitude.
Then, students explore the concept of Earth rotating 15 degrees per hour. This lesson explains conceptually and mathematically why every time zone is 15 degrees apart, and why every 15 degrees of longitude is equal to one hour. An easy acronym is utilized to help students remember that time will get earlier as your travel to the west, and time will get later as your travel to the east. Examples are provided to allow students to practice with time and longitude.
This extensive bundle addresses two essential questions:
(1) How can latitude and longitude help us locate places on Earth's surface?
(2) How can longitude tell us what time it is?
Two different PowerPoint presentations are included in this bundle:
(1) Latitude & Longitude (16 slides)
(2) Time & Longitude (15 slides)
In addition to the detailed PowerPoint presentations, this bundle includes lesson plans, guided notes for the PowerPoints, an entrance ticket, and several practice worksheets.
