Odiorne Point Tides and Zones

For this field trip it began with us going on the bus and drawing on each other. Then we walked safely along the sidewalk and came to the ocean. We started by going into the tide pools and I was trying to stay dry. Then I looked next to me and saw Mr. Woolner knee deep in water and I was like whatever, I'm going to get wet. I caught a few little crabs and hermit crabs. Then we had lunch, and some people payed wiffle ball however I chose to go back to the tide pools. Then some of us went with Mr. Woolner to see the drowned forest and touch the tree stumps. Then we got back on the bus and headed to Johnson's. I got mint chip ice cream and since I was on the track bus we headed home early and then I played hockey in Mr. Woolner's room for the rest of the school day.

The tide happens because of the gravitational pull of the moon. It makes a bulge of water and as the earth spins the bulge moves so that it is always facing the moon. This creates the tide and makes it change.

       The first tidal zone is the black zone, also known as the splash zone. It is mostly black rocks that are covered in a greenish tinted Cyanobacteria.

       Next is the white zone, this zone still has black rocks however they start to be covered in little white barnacles that attach to them and then die there for they live a very boring life. All of the rocks below the white zone also have barnacles but this is where the barnacles start.

       Next is the brown zone, the brown zone is covered in two different types of kelp called Rockweed and Knotted Wrack. They cover the rocks making them brown and very slippery.

       The final zone is the Red zone. Red algae growsmhere along with Irish moss that mostly stays under the water. At low tide the red zone is about halfway under the water.

I saw lots of cool things on my trip to Odirone Point. To begin I saw lot of plants. I saw Knotted Wrack and Rockweed and actually popped some of the air bubbles and they splattered on me. I also saw tree stumps in the Drowned Forest, we touched the tree stumps that looked to be rotting away and they were only have 3-5 inches about the ground and mostly did not come out of the water even at the lowest of tides. Next I saw some things that are can move, however they didn't so they were very easy to catch. I saw a pink starfish, a sea urchin that moved and I didn't find it very spikey, I saw limpets and barnacles. My favorite out of these were probably the sea urchin because the way that it moved was really cool. Finally, I saw things that had to be caught. I saw quite a few big crabs, lobster, baby lobster, hermit crabs (wrestling), and baby crabs. These were all really cool because while you were holding them they were moving so the crabs were pinching people and you had to be careful.

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

The most Variety is in the red zone because it has most of the things in the zones above it because it has the most variation in water height so many things can live in it.
