The temperature on Earth begins to cool shortly after sunset, influenced by local conditions and whether a location is gaining or losing heat. During a total solar eclipse, temperatures can drop along the eclipse's path due to the temporary absence of sunlight. Observations indicate that cooling can start even before sunset, depending on specific environmental factors. Resources from Space.com and NASA provide insights into temperature changes during such events. Recording and analyzing these temperature shifts during the upcoming eclipse is anticipated to be an engaging activity.
