After-school science begins with a bounce

Kelly Nguyen and Jadya En are discovering that science can be messy during their afterwards-schoolhouse program at Garfield Elementary School in Oakland.
The 4th and 5th graders shook their bodies and moved around the classroom because that'southward what gratuitous molecules do. They then linked arms with their teacher to course a human polymer.
Later understanding what a polymer is – a long string of similar groups of molecules linked together – the students had a run a risk to manipulate a liquid polymer to make a solid bouncing brawl. The students in the after-school program at Garfield Elementary School in Oakland tried different combinations of Elmer's white glue (the polymer), Borax, corn starch and warm h2o.

Students in Jeremy Lee'due south subsequently-school form at Garfield Elementary in Oakland link arms to make a human polymer.
"I e'er watch experimenting stuff on YouTube, but I never tried it myself," said Nang Moon, x, dressed in a bright pink jacket.
In his after-school course on a Wed in mid-November, teacher Jeremy Lee was using this interactive arroyo to aid students grasp the Next Generation Science Standards, which are starting to be implemented statewide. The standards include integrating applied science design into scientific discipline education.
Some districts, including Oakland and San Francisco Unified, are looking to afterwards-school and summer programs every bit 1 way to introduce students to scientific and engineering concepts in a more relaxed and fun temper that encourages experimentation.
"After-school programs are a tremendous opportunity to do scientific discipline," said Kasey Blackburn, who manages after-schoolhouse programs for Oakland Unified. In that location are currently 15 after-school elementary programs and 10 heart school programs in the commune that offer science, she said. The Garfield program is run by the Due east Bay Asian Youth Eye in Oakland.
The Garfield students are likewise learning how to think similar chemical engineers and "talk like mini-scientists – using full sentences and citing evidence," said Nikita Williams, site coordinator of the subsequently-school program at Garfield, which serves 164 2nd- through 5th-form students, with about 20 students per class. The E Oakland schoolhouse educates 700 more often than not Latino and Asian students, with almost two-thirds eligible for gratis and reduced-price meals. Although the program operates on a get-go-come, get-go-served basis, teachers encourage parents whose children need extra support to use. The program highlights science and engineering on Wednesdays and Fridays.

Julianna Lopez, 8, is excited most making a bouncing ball from mucilage, borax, corn starch and warm water.
In Lee's grade, the students were focused and supportive of each other's efforts.
"I liked working together to accomplish something," said Camren Em, x, quick to enhance his hand to answer his teacher's questions. "It makes information technology easier."
Learning how to interact is another key component of both Mutual Core and Next Generation standards.
The billowy brawl experiment was put together by Techbridge, an Oakland-based nonprofit defended to helping girls develop a passion for applied science, scientific discipline and engineering. Techbridge provides projects and trains afterwards-school program staff for both Oakland and San Francisco Unified. The organisation has been partnering with Oakland for v years.
"Information technology was important to create a professional person development structure," Blackburn said. "Some of the staff were terrified well-nigh doing science and their personal knowledge was low."
Techbridge understands that they are non dealing with credentialed science teachers, said Tiffani Quan, who is in charge of training the after-school staff. "We take a set of activities specifically written so line staff without the scientific discipline background are comfortable leading the activeness," she said.
Lee, who is pursuing a degree in business and accounting at CSU East Bay, said science did non come up hands to him as a high school student. "It was intimidating," he said. But he is relaxed and confident fielding questions from his students. He said he wished he had had a similar experience growing up.
"They are learning that they can always go back and redo information technology – to try again," said Jeremy Lee, an after-schoolhouse teacher at Garfield Elementary in Oakland. "This experiment besides gives them the sense that at that place are options rather than one right answer."
"If students see that scientific discipline is fun, then they will remember differently about information technology when they get to loftier school," he said.
Quan said she trains the after-schoolhouse staff to ask open-ended or guiding questions.

Thuyen Hoang, 10, left, Nang Moon, ten, and Julianna Lopez, eight, "squish" the purse to form a ball.
In Lee'southward grade, the conversation near polymers ranged from making soft drinks – and why too much sugar is bad for y'all – to why in that location are different types of gasoline.
"They might exercise different things," Nang suggested.
Afterwards a group word, the students bankrupt into groups of 4 and mixed the ingredients post-obit 3 formulas given to them, marking off a checklist that had them describe the "concrete properties" of each mixture as liquid, milky, chunky, gummy, mushy, gummy or solid. Most chose mushy.
"Why is information technology important to test different formulas?" Lee asked the students.
"So an engineer can make it better," offered Griselda Aleman, x.
After testing the three formulas – "squishing" the mixtures for i minute, per directions – each pupil worked on his or her ain to detect the correct combination of ingredients that would brand the ball bounce highest.
Some of the balls – including the teacher'south – were apartment or watery. Lee gave those students plastic bags of the chief ingredients to have home.
"They are learning that they can always go back and redo it – to endeavor over again," Lee said. "This experiment likewise gives them the sense that there are options rather than one correct respond."
Linda Kekelis, CEO and executive director of Techbridge, said that understanding the importance of failure is one of the most important elements in scientific discipline education.

Eljarod Lawson, Jr., 10, left, Tu Doan, ix, and Harry Robles, ten, discuss the science projection.
"Real science and real engineering is all about what doesn't get correct the kickoff time," she said. "You lot get back and tweak and redesign. We want to encourage kids from the starting time that that is what learning is."
Students who managed to create a solid ball could make it red, blue, green, yellow or some combination with drops of nutrient coloring.
In Ana Lopez's class of 2nd and third graders, the run a risk to create their own colors created quite a buzz.
"I mixed ruddy, green, yellow and blue and got brown," said Amir Rey, 7. "I think I'thou going to have to have morecolors."
Julian Mireles-Zepeda, 7, had fabricated the same option but with less enthusiasm. "It looks like mud," he said matter-of-factly.
Amanda Turton, who teaches science at Garfield to all grade levels, said she volition ofttimes take a peek into the after-school classrooms to run across what the students are doing.

Jonathan Phuong, 10, left, and Thien Au, 10, are having fun mixing their ingredients.
"I see them so excited," she said. "I borrow the ideas for my classes." Even if the action is a bit different, the students who participate in the after-school program "get it right away," Turton said. "Then they can help the others and become the leaders of the class."
Turton said Garfield students compete in a districtwide science off-white each year and have brought dwelling some awards. Last year she picked three projects from her classes and three from the afterwards-schoolhouse program. The after-schoolhouse projects included comparing solar ovens fabricated out of aluminum foil and paper-thin. The projection showed pizza boxes worked the best.
Another project had students figuring out which vegetable was the all-time usher of electricity. Think once again if yous're eating broccoli during a thunderstorm.
The students seem to agree that science is fun – an initial survey of after-school students who participated in the science lessons found almost felt positive virtually scientific discipline, Blackburn said. Merely the program has not yet convinced Jonathan Phuong, 10, and his friends that they want to become scientists.
"I've seen scientists in movies," Jonathan said, as his friends nodded in agreement. "They lose their minds."
