Nurses and nursing students...I am taking peds, we have to go to a headstart and make a teaching plan.?

I need to list at least three measurable, behaviorally stated client learning objectives.

Which I haven't finished completely yet because I am still deciding on the topic. Obviously, it has to be nursing/health related and go with the teachers theme. The teachers theme is stars and planets, I thought about doing a healthy earth and healthy earthlings type thing where I would focus on healthy community such as recycling, not littering, finding ways to help the earth etc... or healthy earthlings (or healthy astronauts) and just focus on exercising, food guide pyramid (healthy meals and snacks), and ways to stay healthy.

Do any of you have any ideas for me? I need to make a few activities.
