PHILADELPHIA (CBS) – Some Philadelphia teachers are getting an opportunity for free science training.
Chemist Frank Zawacki showed kids at the Hill Freedman Middle School in West Oak Lane what happens when you drip a sodium alginate solution into calcium chloride.
“It goes from this slimy goo to what we would call a gummy worm,” said Zawacki.
Seventh grader Diamond Hannah felt it.
“Its hardening and it’s kind of gooey and it feels like rubber a little bit,” said Hannah.
Zawacki’s firm, the FMC Corporation, is giving $100,000 to provide training workshops for teachers at the Philadelphia Science Festival later in April.
“Hopefully what they’ll do is they’ll be able to take what they learn and create more interesting things, hands-on things for kids,” said Hill Freedman principal Anthony Majewski.
