Maiʻa by Hiroki

The Maiʻa leaves were used to cover the food placed in the Imu.They were also used to make temporary sandals.
The Maiʻa trunk from banana and plantain trees here used as rollers to move large canoes. The Maiʻa Fruit was eaten raw or cooked.


Hala by Elizabeth

Hala is a strong, bumpy tree that is used in mats and houses. It is the symbol and has a lot of history connected with Punahou. It has some roots that are exposed and the roots are bumpy too. The tips of the aerial roots are rich in vitamin B and eaten raw or cooked for medicine.  


About Wauke by Lucas

Wauke is used to make clothes by pounding it a lot which makes it into a soft cloth. Wauke grows mostly upward. And Wauke was one of the Hawaiians most important plants because, well, it made their clothes. It took a long, long, long time to make the clothes. It would take about 3 months to make one piece and it took a lot of pieces to make a full piece. The Hawaiians pounded two pieces a lot at the same time to connect the fibers together to make a bigger piece.

Koa by Kate

Did you know that the Koa tree is endemic? It is endemic because it is native to Hawaii and found nowhere else in the world.

Some facts are that the Koa trees are found in drier forests on mountain sides.When the trees grow closer together, the trunks grow straight and tall (up to 60 feet tall) before beginning to branch out. You know it is a Koa tree if the leaves are small and oval shaped.

What are some of its uses? The trunks are used for canoe hulls, paddles, surfboards, and calabashes. They don't use it for bowls because the sap has a disagreeable flavor.  

Hanauma Bay by Kate, Elizabeth, and Hiroki

On Monday, July 1, we went to Hanauma Bay. First, we watched a movie that provided us with information on how the bay was made, rules for what we should not do while snorkeling, and what we can do to help the environment. Four things we learned were: 1) don't step on the coral, 2) don't feed the fish, 3) look, but don't touch, and 4) don't litter. The reason they don't want visitors to step on the coral is because it will break off and die. The reason why we shouldn't feed the fish is because human food can cause them to sick and die. The sea animals and organisms in Hanauma Bay have plenty of food to eat in their natural habitat. The third one informs us that coral will die if we touch it or break it off. Also if we touch the fish, they will get scared and maybe leave, so we won't be able to see them in the future. The last message tells us not to litter because it will go in the ocean and the marine animals will eat it or get caught in the trash. We learned that most of the trash takes hundreds to thousands of years to decompose.



Learning about tuff, compressed ash from when the volcano was active.

What is left after the crab has molted! 

When we got to the beach we jumped in the water and started snorkeling out. As we were snorkeling, some of us saw a sea cucumber and sea urchins hidden in the reef. We went out farther and saw a turtle swimming and an ulua (silver fish) next.  There was an eel coming out of its rock and swam right at us. He scared us with his big eyes and mouth! After that, we got out of the water and dried off and went back to the bus.

If we don't take care of the environment the fish will become extinct or very sick because the water might get murky and dirty, so the coral will die and the fish will starve to death.


Intertidal Zones by Aidan, Kira, and Bryant

On Tuesday, July 2nd we learned about intertidal zones. Within an intertidal zone are vertical zones.

The first vertical zone is the splash zone, also called the upper littoral. This is dry most of the time and is sprayed by the water in high tide zone. The splash zone contains tide pools and it is only covered when it is super high tide or there are storms. This area has little organisims; they include barnacles, isopods, lichens, lice, limpets, periwinkles, whelks, and very little vegetation grows in this area.

Next is the high tide zone, also called the upper mid-littoral zone. This area is only flooded during high tide. Organisms in this area include anemones, barnacles, brittle stars, chitons, crabs, green algae, isopods, limpets, mussels, sea stars, snails, whelks, and some marine vegetation.

The middle tide zone is also called the lower mid-littoral zone. This area is turbulent and is uncovered and covered twice a day. You might find anemones, barnacles, chitons, crabs, green algae, isopods, limpets, mussels, sea lettuce, sea palms, sea stars, snails, sponges, and whelks.

The last vertical zone in the Intertidal Zone is called the low tide zone, also known as the lower littoral zone. This area is always underwater. It is exposed when it is unusually low tide. This is harmful for many animals because they need to live in water and some don't know how to adapt to temperature changes. Creatures in this area are not well adapted to long periods of dryness or extreme temperatures. Some of the organisms in this area are abalone, anemone, brown seaweed, chitons, crabs, green algae, hydroids, isopods, limpets, mussels, nudibranchs, sculpin, sea cucumbers, sea lettuce, sea palms, sea stars, sea urchins, shrimp, snails, sponges, surf grass, tube worms, and whelks.

Animals that live in the Littoral Zone have a wide variety of predators who eat them when the tide is in. The organisms we have mentioned are preyed about by sea animals like fish. When the tide is out, these organisms might be hunted by land animals such as foxes, people, birds, and marine mammals like walruses.

He'eia Fishpond by Steve, Kara, Haruka and Lucas

Heʻeia Fishpond
by Steve, Kara, Haruka and Lucas

Experiences at Heʻeia Fishpond

1. We chanted 'Eia ka Punahou'
2. We made a circle and introduced ourselves.
3. We felt coral and rock which made the wall and described it.
4. We all tried Akulikuli and it tasted like G2
5. We went to the makawai (gate) where the Hawaiians would collect the fishes.
6. We weeded out mangroves and got very muddy.







Questions

1. What did the Hawaiians use the fishpond for?
A. They used the fish in the fishpond as food and fish was their only source of protein. The fish was a kind of food for the people in the ahupuaʻa of Heʻeia.

2. What materials were used to build the pond.
A. Pohaku (Lava Rock) for the outer wall and Koʻa (Coral) for the inner wall where we walked on. 

3. Why is mangrove harmful to fishponds?
A. It sucks the nutrients from the fishpond and makes the dirt black.

4. Interesting Facts 

1. A fishpond has 2-3 guardians, like the moʻo.
2. Another guardian is a sting ray and if someone tries to steal, it stings him or her in the neck and tie him or her up then, throw him or her to a reef with a lot of sharks.
3. The mangroves can grow at least 1 foot a year.
4. The fishpond is 800 years old!!!
5. The fishpond is 88 acres (it can fit all of Punahou School inside it).
6. The coral and rock wall has been stable for 800 years.
7. The fishpond is not that deep so we can walk across the whole fishpond.
8. There used to be 98 or 99 fishponds but now there are only 10 on Oahu.
