Generate a consensus based on data. Communicate experimental procedures and findings orally and in writing. Collect, organize, display, and interpret data for a given situation using appropriate displays. Use data analysis to write an evaluative argument in a real life situation. You are growing bay grass to plant in the Chesapeake Bay to restore habitat for many bay creatures.
Salinity varies throughout the Bay and changes depending on tide, rainfall and time of year.
You will simulate the growing conditions of the Chesapeake Bay in growth chambers. Background Refer to the Vallisneria americana Fact Sheet Lesson for background information about wild celery. See diagram below. However, you may add water to compensate for evaporation without affecting the salinity. Students will compare the growth rates of the wild celery plants in the two chambers by creating a line graph of their data.
