SAUGUS — Kids got to head to the Saugus Public Library Friday morning for a lesson in science from the educational entertainment company Science Heroes, giving them a chance to join in on experiments and learn a few fun science facts during school break.
Presenter Brianna first gave the kids safety rules, including staying behind the yellow line and listening.
She then told the kids that the story they’d be listening to today was the Case of the Missing Color, where Briana would be searching for her favorite color with the help of her new fellow science heroes.
The science mission began with her searching for the color blue at the beach.
“Me and my best friend we’re swimming in the bright blue ocean. And when we go out onto the sand, we start to dry off. That’s when I noticed a beach ball,” she said.
She then taught the kids about air pressure and how filling the ball with too much air would lead to it popping. She also pulled a volunteer from the audience to show how air travels by filling up a five-foot-plus bag in one breath.
“What happens is when I blow air, that fast-moving air makes a space of low pressure inside my bag. But pressure wants to be even. Since I left space between my mouth and the bag, there is enough space for it to take the really high-pressure air out here and pull it right into the bag,” Brianna said.
She then took the kids on the next step of the mission, the color yellow. Here she taught the kids how, when you leave lemonade outside in really hot temperatures, it can evaporate. This led up to an experiment on the water cycle and making a cloud in a bottle.
“We’re going to use a chemical called isopropyl alcohol, also known as rubbing alcohol,” she said, pouring some of the liquid into a larger bottle.
Brianna, with the help of some volunteers, then used a bike pump to fill the bottle with air, and once the pressure built up, a loud popping noise filled the room, and a cloud appeared in the bottle.
The experiments continued with kids going up to join the interactive experience, ending with a bubble volcano as the grand finale.
