is a breeze for the out of town football high school freshman team. certainly not a problem for grandma. >> i am a grandparent of number 55 on the foothill high/ pleasanton team. j.r.: not a problem as long as the water is served up, downed and sprayed. >> we use this at disneyland when it gets hot. it is a fan. you just kind of spray. >> that's not normal, not normal. we are enjoying it. j.r.: some folks did not feel comfortable watching the game outside in these triple digit temperatures. those folks opted to go inside their car, where it is air-conditioned. >> very cool. that's the beauty of a car with air conditioning and cool seats. j.r.: while most of the parents are confident that their kids have been drinking lots of water. >> make sure he's all hydrated.

california has less hydroelectric power. california does not have the capacity to store huge amounts of solar energy. >> enough storage to store solar energy from the middle of the day and kind of move it to the evening. anser: that's why flex alert is issued, to conserve power and prevent blackouts. >> the surprising thing is how much of a difference individual homes can make. anser: the ceo of home connect, a free service that notifies customers on how to reduce power. he says the average home in california uses two kilowatts of power. 500 homes make up one megawatt. in august of 2020, when california was hit with blackouts, demand exceeded supply by just 500 megawatts. he said if households reduce energy use by just 25%, it could prevent blackouts. >> about 50,000 customers to produce their energy use by a

experiences and breaks down those numbers. tim: it is often called the nation's report card. the national center for education statistics releases data from an assessment given to nearly 15,000 kids twice a year. it shows how american students are performing in key subject areas. on thursday, new numbers reveal that since the start of the pandemic, the country has received a failing grade. >> maybe two grades below level, which is tragic in and of itself . tim: from the start of 2020 through the winter of 2022, the covid pandemic and ensuing lockdowns resulted in a learning loss that erased decades of progress. in math and reading, nine-year-old students were knocked back to levels not seen since the 1990's. the trend has caused alarm among both educators and parents.

>> it>> was easy for people who were not with them each day to say the kids are doing fine, they are resilient, they will get through this. parents who were at home were saying the kids are actually not all right. tim: while the learning losses were broad-based across nearly all groups, students of color were disproportionately impacted. >> i think to contextualize that, i think part of that is because so many of our students of color in the state were already in schools that were under resourced, under invested in, and then you add a pandemic on top of that. tim: since returning to in person learning, parents and teachers have been working overtime trying to catch students up. many say they still worry about the long-term effects. >> these academic numbers i feel are actually just the tip of the iceberg, they are not even addressing the social/emotional losses that happened. tim: unless more steps are taken to try and address the learning losses immediately, some fear they could haunt us for years to come. >> i fear we are going to see a cliff 3, 4, five years from now where we are going to have a
