Land vs. Water Uneven Heating Investigation | Weather Lab | Sea Breeze CER
Make uneven heating and local winds come to life with this hands-on Land vs. Water Investigation!
In this 2-day weather and energy lab, students investigate how land and water heat and cool at different rates. Students collect real temperature data, create a line graph, analyze their results, and use evidence to explain what they observed.
Students then connect their experimental results to a real weather phenomenon by modeling and explaining how the uneven heating of land and water can contribute to the development of a sea breeze.
Designed for grades 6–8, this investigation combines hands-on science with data analysis, graphing, CER writing, and weather concepts in one ready-to-use resource.
