Students rolled compost, soil, sand, and 3 types of seeds into balls. These seed bombs will be thrown at a field trip on April 14th to Coldwater Spring, a part of the Mississippi National River and Recreation Area that is being restored to an oak savanna/prairie complex. FSMN students have been going to Coldwater Spring and doing service work there since it opened in 2012.
Students calculated the average number of seeds per bomb (385), the average number of bombs per bowl (9), bombs per tray (90), and total number of trays (19)and total bombs per class. They then figured out how many square feet of prairie they were helping to restore and what that would look like if it were a perfect square vs the many rectangular or other geometrical options! The 1710 bombs made by 5th and 6th graders mean they will be dispersing about 658,350 seeds in April when they go throw them at Coldwater Spring. They figured that their seed bombs would plant 855 square feet of new prairie if they were seeding new land! However, at Coldwater Spring, our seeds are actually enhancing larger amounts of prairie that is already in the process of being restored.
