The heat across KOTA Territory put strain on students in hot classrooms Monday.
Temperatures soared above 90 degrees before noon, and classrooms weren't much cooler.
Teachers kept their students hydrated by handing out popcycles.
Superintendent of Rapid City Schools, Dr. Tim Mitchell said he personally visited the older, hotter buildings to monitor the conditions in classrooms. And, he keeps in close contact with principles to see where the classroom temperature begins and where it ends during these hot days.
"The key for us is going to be brick buildings that can heat up quickly. But what happens at night is key as well because if we can bring in the cooler air at night into classrooms, we'll be better off," Mitchell said.
And, though the heat was intense, Canyon Lake Elementary Principal Bradley Tucker said they are taking it in stride.
"We joke about it, in fact I've joked about it several times today. But when it comes to it we are here for a reason and we will stay in school until the heat index is intolerable."
Temperatures reached over 92 degrees inside Canyon Lake Elementary Monday.
If schools shut down early this week, Mitchell said parents will be notified by the automated phone-dialer system. And it will be district-wide.
About half of the classroom buildings in the Rapid City School District don't have air-conditioning.
