ProceduresFirst, I put on my gloves and safetygoggles for protection. Then, I put on myface mask so I can’t breathe in the smell,after that I took my ruler and measuredthe pellet in cm. Next, I carefullyunwrapped the tinfoil and carefully pulledit apart and began removing the bonesfrom the pellet. I used forceps, a probe, a ruler, safetygoggles, latex gloves, one small foam trayto put the bones and any other things Ifound on, and one big tray to put thepellet on when I was taking it apart.
ProceduresAfter we ﬁnished taking out our boneswe soaked them in bleach then we setthem outside to dry. We bleached themto make them whiter because they werea yellowish color because they had notbeen exposed to the sun for them to bebleached out.When we were ﬁnished we took ourbones and glued them on a piece ofblack paper in the order of a rodentskeleton.
Pellet InformationMy pellet was 3cm in lengthand 1 1/2cm in width. It wasdark brown with a few signs offeathers and a lot of fur. WhenI ﬁrst tore the pellet gentlyapart I could see a lot of bonesthat were all small.
My SkeletonAll of these bones in theskeleton were from arodent.I had 48 bones total but Idid not know what ten ofthem where so I usedonly 38 to make myskeleton.
Reﬂection of ProjectI learned that owls puke up pelletsthat contain bones that it was unableto digest. I also learned that owls eatother small birds.The hardest part was when we had toseparate the bones into differentgroups depending on what kind ofbones they were which was hardbecause all of the bones looked alike.
Reﬂection of ProjectThe easiest part was when we had to take outthe bones because all of the bones were showing.I would like to learn more about the process ofpellet formation. I thought that this project was alittle gross until I actually did it which was not asbad as I thought it would be. I really would notwant to eat like an owl because it would be hardto puke up a big pellet a few hours after I eat,also I wouldn’t be able to chew my food, andthats bad because I really don’t want to swallowmy food whole.
ConclusionThis project was really fun and I enjoyed it a lot.If I had to choose the best part I would choosethe part when we put our skeletons together,because it was cool to ﬁgure out what bone waswhat, and what bones are supposed to gotogether, even though it was hard I still enjoyedit.
