I have to use the standard, (students know how nutrients, water and sugar is transported in a vascular plant) I need two pre trip activites, one onsite activity and two post activites:

I'm having trouble with the first one which would just be a lesson on Xylem and Phloem ...
Second is Skits....this is okay it would be on Photosynthesis.
Onsite: Worksheet with docent tour
First post activity: Celery experiment to demostrate transpiration
Last: Using pressed flowers decorate a field guide.
