Elevation and Depth Comparisons

This video tutorial covers the concept of sea level elevation using positive and negative numbers, focusing on the vertical positions of various animals. It includes exercises on comparing elevations, a mobile array, and an extension activity involving the North and South Poles. The lesson concludes with ordering rational numbers and a feedback section.
