A maximum of 10 scouts should be at a station with six being a better number. Try to have one adult for every five to six scouts. Provide your SWE volunteers with the information they need to do the activity they are assigned well in advance. Some of the activities require advance preparation of as much as a week. Let your volunteers know what you will be bringing and what the scouts will be bringing so they know what they are responsible for providing.
Several activities call for chart paper, masking tape and markers.
This is something that would be easier for one person to bring. Each activity has a complete materials list. Have your volunteers arrive early to be prepared when the scouts get there and minimize startup time. Provide your volunteers with name tags indicating their name, company and type of engineer or other profession. This is a function that the Girl Scouts can perform for you.
