My Ordiorne Field Trip Experience

The seventh grade went on a field trip with two busses to ordiorne state field trip. we hung out, played games, ate lunch, went tide pooling, got ice cream, and returned home.

The tides occur because of the Moon’s gravitational pull. This pull causes the water on Earth to pull outwards toward the Moon, slightly elongating that area of the Earth. The side directly opposite the Moon at any given time, is also elongated because of differences in the Earth and Moon’s gravitational pulls. This pull is high and the two sides in between are low tides.

The first zone is the Black Zone, it is black because of cyanobacteria. Cyanobacteria is a poisonous substance that is very slippery. Next is the white zone which is covered in barnacles. Then the Brown zone is full of kelp. Also the red zone is red because of Irish Moss. I did not mention the subtidal zone or dry zones.

While at Odiorne, I went tide pooling to find creatures with my grade. I found many creatures and cool items on, under and by rocks, also just in the water. I saw many, green crabs, and hermit crabs moving around in the water. I also saw some sea stars that my other classmates caught and put into a plastic bag before we released it. People also caught lots of other things in the water. we put all these creatures in a tank to observe for the day. when we were done, me and some of my friends returned the creatures back to the water before we left.

WHERE is there the most variety, and WHY do you think this is?

I saw the most variety in the red and brown zone specifically. In the brown zone, I saw lots of kelp and also creatures. However, I saw more variety of crabs when I was in the red zone. They were everywhere! Under rocks, and in the sand, also just floating and traveling around. I think there is the most variety in these sections because it is slightly submerged, but not fully underwater 24/7. This would make sense because that means many different type of organisms can live there. Organisms that need to stay mostly dry, can live in sections of the brown zone. Also, organisms that need to be underwater form most of the day, can survive here in the red zone. This is why I think these are the zones where I saw the most variety in life.
