In order to determine how much

*Gracilaria*is available for use by*Diopatra**,*and really how much is drifting onto the mudflat, we are manipulating the "_R" plots by photographing and then removing the*Gracilaria*each site visit. The algae removed is weighed and that information is recorded. The data below is from this month, August 2015.## 5th grade activity

Hey 5th graders! You’ve learned how to represent numbers in different forms. The above information is in a table. What if we wanted to represent this as a graph? What kind of graph would you create? Try drawing this information in a bar graph. What plot has the most algae? Which has the least?

## 7th and 8th grade activity

Find the mean

*Gracilaria*mass removed this month. Next, go back and look at the data from January 13, 2016. Find the mean*Gracilaria*mass removed on that day. Compare and contrast the amount of*Gracilaria*removed in August versus January. What do you notice between these two different seasons (summer versus winter)?
