Fourth+Visit+Journal

We visited the stream for the fourth time on Sunday, November 30, at 1:30 p.m.

It didn't rain recently, so the grass wasn't all washed over like it was during our last visit. Although, during this visit, everywhere we went, there were tons of mosquitoes biting us left and right, front and back. Whenever we visited there before, there were never that many mosquitoes. All of the plants seemed to have grown a lot since our first visit, and the stream is still a little damaged after that storm.

My hypothesis was... If there were areas of dirt under different filters of light, then the dirt with the darkest light (no light) will have the most cockroaches in it after 24 hours. Materials: - 2 cardboard shoeboxes - blue saran wrap - red saran wrap - 10 wooden pencils - cutting device - tape - hammer - shovel - 4 containers to hold dirt - 4 labels (Control, Blue, Red, Dark) Procedure: 1. Cut shoeboxes in half 2. Cut off lids of shoeboxes 3. Cut the lids in half 4. Tape the 4 halves of the lids onto the sides of the 4 half-boxes (You should now have 4 mini boxes with an open end) 5. For 3 of the 4 boxes, remove (cut off) the end opposite the open end 6. Choose 1 of the 3 boxes and tape blue saran wrap on one open end (4 layers) 7. Repeat step 6 on another box using red saran wrap (You should now have one box with 1 open end, one box with 2 open ends, one box with 1 open end and 1 end covered in blue saran wrap, and one box with 1 open end and 1 end covered in red saran wrap) 8. With the excess cardboard on the sides of the boxes, fold them outward so they become flaps 9. Cut a small hole in each flap, wide enough for the pencils to slide through and not be loose 10. Insert a pencil through each hole 11. Clear all rocks, twigs and leaves from an area of dirt 12. Place the 4 boxes, open end down, on the dirt next to one another 13. Using the hammer, pound the pencils into the dirt to stabilize each box 14. Let the boxes sit in place for 24 hours and return to the area with shovel and containers (One label placed on each container) 15. Using the shovel, dig into the area of dirt one box was covering (6 inches deep) 16. Place this dirt into the container with the label matching the box you chose (Control=no covering, Blue=blue saran covering, Red=red saran covering, Dark=box with only one open end) 17. Repeat step 16 for each box 18. Count number of cockroaches in each container and record data 19. Compare numbers and record observations and trends This is what the boxes looked like, and the last picture on the bottom is the trees directly above the boxes. This is so you could see where the sunlight comes in from and what kind of sunlight it is receiving.

DATA TABLE From this data, I've concluded that the sunlight doesn't have a **major** impact on how many cockroaches travel to that specific area. I say this because the two areas with the highest amount of cockroaches were the dirt under the complete darkness box, and the control box. Since these are the two opposite boxes and they got similar results, that must mean that the light doesn't make a difference. If it did make a difference, then an area of dirt that is in complete darkness would get more cockroaches. If we could do this experiment again, I think I would change the way that we dig up the dirt, because some cockroaches could've crawled out of the area while we were digging. I think I would also give it more time so that the cockroaches would have more time to migrate to their chosen areas.
