Program Management System - 21st BCCE - Chemistry Experiments for Outreach to Elementary School Students
||Chemistry Experiments for Outreach to Elementary School Students
||This workshop will be a hands-on experience of three experiments that we use in our visits to elementary schools around the province of British Columbia. Each student that we meet does an experiment that is appropriate for their age group, typically Kindergarten - grade 2, grades 3-5, grade 6 and above. The experiments are (a) making slime (b) making an indicator and identifying an unknown kitchen powder and (c) analyzing the thiocyanate in saliva. We will describe the structure of the program known as Scientists and Innovators in the Schools but the primary focus of this workshop is to let the participants see how it works in their own hands.
