Behind plexiglass guards and in Zoom rooms, Rio del Sol Elementary School fourth graders trained their eyes on their individual plastic cups filled with various yeast mixtures. Finally, thick, soupy bubbles began to rise above the rims of some cups.
“It has bubbles!”
“It’s rising to the top, it’s about to overflow!”
“I have bubbles, too!”
“Can I take mine home?”
The yeast fermentation experiment was a hit.
“The hands-on aspect of actually doing or making something really makes the experience more memorable,” said Rio del Sol teacher Jo Anna Mendoza said. “They get the joy of having fun with science and learning along the way.”
The activity resulted from one of 75 do-it-yourself science experiment videos created by CSU Channel Islands (CSUCI) students from various majors for more than 550 Rio del Sol STEAM Academy students in grades K through 8.
