When and How: This can mostly be done in a single meeting, with a followup two weeks later. You might want do do this in early November, just before cold and flu season, since the habits in 3b will be most useful then.
Special needs Scouts: 3c is a good example of a "show you know" requirement. The Scout is not required to actually bandage a finger. They can describe it, talk another person through the steps, arrange picutures in the right order, or use any other method in order to "show what to do for a small cut on your finger."
3a: Make a chart and keep track of your health habits for two weeks.
Notes: For each Cub, make a page of daily milestones, like meals, recess, and bedtime. Then associate healthy behavior with each daily activity. Have the kids suggest things first, and have them all write them down on the pages. Have them fill in their bedtimes and when they get up in the morning, so you can talk about getting enough sleep.
Resources: Print out this daily activity chart for the Cubs to use. You might need to adjust the size (use your browser controls) or the number of rows (edit the file). Make it big enough, because Wolf Cubs need lots of room, even for check marks.
3b: Tell four ways to stop the spread of colds.
Notes: This isn't about memorizing the four ways. It is about the cause of colds (viruses) and how to keep from spreading them. Talk about how each of these keeps friends and family from getting your cold.
3c: Show what to do for a small cut on your finger.
Equipment: Adhesive bandages, soap, running water, and a non-permanent red marker.
Notes: Use the marker to make a "cut" on a their finger. Make it small enough to fit under the bandage and to obviously be a "small cut", probably less than a half inch long. Then go through the steps: tell a grown-up, let it bleed a little, wash it with soap and water, and cover it with a bandage. The red marker makes a big difference. The kids are pretty serious and careful about their "cut". This approach is useful in first aid training at all levels. An imitation wound or other condition is very effective, even when it is obviously fake. Physically practicing the steps is the other key part.
If any of the families are not there for the meeting, make sure to explain that the bandages are just for practice and that their kids weren't injured!
