For our fieldtrip we started out by getting on two different busses. About two hours later, we got off at Odiorne Point state park. We walked towards the picnic tables, put down our backpacks and started towards the ocean. While tidepooling, we found hermit crabs, lobsters, sea urchins, snails, algae-like seaweed, dog kelp, Northern sea stars, and of course we saw Mr. Woolner fall into the water. We played football and wiffle ball on the field, ate lunch, jumped and pranced around on the rocks, walked around. Then we got back to the bus, and on the drive home, we took a pitstop to get icecream at Johnson's Dairy Bar, before finally arriving back at school, just in time for the busses and parent pick-up.
Tides are caused by the moon. The rising and falling of sea level is the gravitational pull caused by the sun and moon, and the earth’s rotation. All bodies on earth are inflenced by gravity, pulling against eachother. The sun and the moon are pulling on the earth together, though the moon is closer to the sun so it has the greater influence. So the moon pulls on the earth, moving the water.
Black Zone - The Black Zone, also known as the Splash Zone, is the highest zone, just beyond reach of the highest tide. It only receives dampness from a splash at high tide, or from rainwater. In this zone lives green-algae, crabs, snails, mussels, barnacles, and sea lettuce. Or at least those are the species that we saw at Odiorne Point, though there are many others.
White Zone - The White Zone, also known as the Middle Zone, is underwater half the time, and exposed and dry half the time. There are white dots on the rocks which is caused by the ciano bacteria. In the middle zone you may find, crabs, sea stars, snails, seaweed, and algae. We go to see all of these on our fieldtrip, and as you may have noticed, pretty much all these species were also present in the black zone aswell.
Brown Zone - The Brown Zone, also known as the Lower Zone, is almost never dry besides during low tides. There is a diverse range of species living in the brown zone, some being knotted wrack, rockweed, gulfweed, and sea potato. We saw an abundance of seaweeds at Odiorne, though I don't believe we came in contact with any sea potatoes.
Red Zone - The last zone is subtidal, which is always underwater. Many species live in this zone, some being Irish moss, clams, snails, worms, eelgrass, kelp, and sea urchins. We came across several sea urchins on our trip, they are facinating. We got to pick them up out of the water and feed them. Their stomaches come out of their body, get food and come back to them.
While tidepooling, we found hermit crabs, lobsters, sea urchins, snails, algae-like seaweed, dog kelp, Northern sea stars, daisy brittle star, irish moss, sponges, barnacles, and limpet. Being by the ocean we also saw the intertidal zones, and obviously all the species living in them.
