Station #2: Fish Pond

Station 2
By: Emma

Last week we went around to four different stations to complete exponential function problems. At the second station, we used either skittles or M&M’s to collect data. This activity was called the Fish Pond activity, to illustrate the growth and decay of the number of fish in a pond. 

First, we recorded the number of Skittles we had. Then we placed the Skittles in a cup, shook them around, and dumped them out onto a plate. We removed all of the Skittles that had the “S” facing down and place the remaining Skittles into the cup. We repeated this until we ran out of Skittles or we had made eight attempts. 

After collecting the data, we answered some questions about the data we had collected and graphed that date. We then came up with an equation and drew that on the graph in a different color to see the difference between the data we collected and our equation. That was an example of exponential decay. 

We then collected data in an exponential growth pattern by  placing some Skittles into the cup, shaking them, and tossing them onto the plate. However many Skittles had the “S” facing up, was the number of Skittles we added. Each toss, more Skittles were added because there were more Skittles with the “S” facing upward. Once again, we answered some questions, plotted our points on the graph, came up with an equation, and compared.
