WHOAAAAH PLANKTON!

Introduction:
"Planktos," meaning "wanderer," is the Greek word in which the life form, Plankton, came from. Plankton are any drifting organisms (animals, plants, archaea, or bacteria) that inhabit the open seas or open bodies of fresh water. They cannot swim against the current or go against the wind. Currently, there are four basic ways to classify plankton. This is by food, color, lifestyle, and size. The food category is split between two different types of plankton, the photo-synthesizers (phytoplankton), and the heterotrophic (zooplankton). The classification of their color varies from greens to reds, browns, blue-greens, and even golden. Within their lifestyle, they can be classified as either holoplankton and meroplankton. Holoplanktons live their whole lives as a plankton, like algae and jellyfish. Meroplanktons live only part of their life as a plankton, like barnacles and larvae. The size of the plankton is divided into three descriptions. These being the megaplankton, the microplankton, and the ultraplankton. The megaplankton usually stay in the less than two millimeters range, the microplankton in the .06 to .5 millimeters range, and the unltraplankton in the greater than .005 millimeter range.

Question: What is the diversity of plankton in South Maui?

Hypothesis/Predictions: I think that we will find around 200 different types of plankton in South Maui. I think this because there are endless of various types of plankton in the world, and this is how little, or many, I feel we will come across.

Materials:

• Plankton Net
• Vial (s)
• Jars
• Journal
• Pipette 
• Microscope
• Slides
• Cover Slips
• ID Book

Procedure:

1. Gather materials and head to your area of collecting the plankton
2. Record the beach and other specifics like the temp. of the water, salinity, dissolved oxygen, phosphates, nitrates, current/tide/waves, pH, sunlight/time, and the wind.
3. Using your plankton net, drag it in the water for a total of three minutes.
4. After, take the collection vial located at the bottom of the plankton net and transfer the liquid inside the vial into another container.
5. Take your collection back to the lab.
6. To test and see the different types of plankton, using a pipette, drop some of your plankton water on a microscope slide, along with a drop of water. Then, cover it with a cover slip.
7. Place slide under a microscope and using the different magnitudes, observe the plankton on the slide.
8. Count the different species you see.

Data:

• Temperature-20.4 degrees C
• Salinity-26% at 1:20 PM
• Dissolved Oxygen-0
• Phosphates-4
• Nitrates-2 
• Current/tide/waves-High tide
• pH-8.09
• Time (Sunlight)-12:50 to 12:56
• Wind-Slightly breezy

In the Lab...

Microscope Procedure:

1. Get your materials out. The microscope, slides, cover slips, plankton sample, pipettes, ID book, journal, pencil/pen, and 
2. With your pipette, collect some plankton sample and squeeze it onto a slide. If needed, use the to slow the plankton down and make them more identifiable. Cover with a cover slip.
3. Make sure the microscope's light is on and place the slide onto the microscope. 
4. Look through the lens to see what needs adjusting. You can use the three different magnifying lenses and the fine and corse knobs on the side. Do so until you see your specimens clearly. 
5. Record what you see. Draw and label the different types of plankton that you see.

Pro-scope Procedure: 

1. Get your materials out. The pro-scope, a computer with that software on it, examining dish, plankton samples, journal, pencil/pen, and 
2. Pull up the software on the computer and plug in the pro-scope.
3. For the examining dish, use your pipette to squeeze some plankton sample into the dish. If needed, use the to slow the plankton down and make them more identifiable. 
4. Making sure the pro-scope and computer are on and working properly, place your dish under the pro-scope. Move it around, even touching the plankton sample, until you get a clear picture of your plankton.
5. Record what you see. Draw and label the different types of plankton that you notice. With the pro-scope, you can also take pictures of what you see by clicking the "capture" and "stop capturing" button on the screen (the software on your computer).

Conclusion and Possible Sources of Error:

My question for this plankton experiment was: What is the diversity of plankton in south Maui?. Through this, I have identified about six different plankton species. This was only my identification individually, I am sure the rest of the class found those and more. So looking back on my hypothesis, I see that my estimation was far off. I thought that we were going to find 200 plankton species and I only knew of identifying six. All though I tested this scientifically, there could have been many cases in which something went wrong. The possible sources of error that I could have come across are the mis-identification of the plankton under the microscope or pro-scope, not catching an accurate amount of plankton in the net, not carefully transferring the plankton from the catching flask into a beaker, loosing some of the plankton sample that we caught, and plenty other things.

Beach Profiling

OooOooOooo now off to the good 'ole beach profiling! What is beach profiling? The technical term is that it is the intersection of a beach's ground surface with a vertical plane perpendicular to the shoreline. This just means that beach profiling is recording the surface of the beach. We want to do this because wind, rain, waves and other factors contribute to how the beach can change throughout seasons. It can create the beach to have more sand, less sand, bigger dunes or no dunes at all. Calculating it is a good thing, fore it lets us see how the weather and other elements can effect the beach and how quickly it did. It helps us understand how vastly the beaches surface can change in an amount of time. 


In science class, we tested this ourselves. To do this, we needed the following materials:

• Data Sheet-To collect the distances, height, location, as well as recording the visuals of the area. 
• GPS Navigation System-To get the exact location of our profiling spot. 
• Compass- To calculate the exact degrees of our profiling area.
• Camera-To take pictures of our beach profiling experience. 
• Transect Tape-
• Rise and Run Tools

 Our procedure was this:

1. Go to location with materials.
2. Once at your location, find the latitude and longitude coordinates of your dune using your GPS. Record these on your data sheet as "Point A."
3. Then, lay your transect tape starting from that point all the way to the waterline. Check to make sure it is perpendicular to the waterline.
4. After, hold the compass tool at "Point A"to find out the direction in degrees of the transect line you just laid out. Record this on your data sheet as well.
5. Place the run tool on the ground at Point A along the transect tape. Looking at the level tool on the run tool, make sure it is level with the ground. 
6. Now take the rise tool and place it at the end of the run tool, level, on the ground and aligned with the transect tape as well. This is "Point B."
7. Look were the rise tool intersects with the run tool and record it as the rise between Point A and Point B. If the dune tilts upwards (going uphill), then the number is negative. If the dune is sloping downwards (going downhill), then it is a positive number. 
8. During each of your point's areas you should record any distinctive features around. 
9. Now take the foot of the rise tool and put it at the end of the run tool. Keep doing this till you reach the "foot" of the beach (where the beach dips) and past the shoreline/wrackline.

Here are some pictures of us beach profiling!

Sand

Another day, another unit. Now we are learning and putting our attention to beaches and their sand. How did their sand come about? What are they made of? Why? There are many questions in this field and we are getting closer and closer to finding them out first hand. To do so, we created a new lab. The question driving this experiment is: Which beaches in south Maui have biogenic sand, and which have detrital sand? For this question, our task is to find two beaches each. Biogenic sand means that the sand was formed by life processes, meaning it may either be constituents or secretions of plants or animals. Detrital is loose fragments or grains that have been worn away from rock. The beaches I chose to identify were Oneuli Black Sand Beach and Makena Big Beach.

I hypothesized that Oneuli Black Sand Beach is detrital because there are rock cliffs and coral all surrounding the coved area. The sand on that beach is rough, like bits and pieces of rock, and dark in color. I think that Makena Big Beach is biogenic because of the texture and size of it's sand. The sand is very smooth, is super tiny particles, and light in color.

The materials we need for this testing:

• Pencil and Paper for documenting
• Camera 
• Cup to collect sand in
• Vinegar
• Pipette
• Safety Goggles
• Beaker(s)

Procedure:

1. Pick which beaches you think are detrital and which are biogenic in south Maui
2. Go to those beaches. 
3. Make observations of the area and the beach you are observing and write them down. Do this either in a journal or on a piece of paper. 
4. With your cups, collect some sand from each spot
5. Once back to your experiment area, put on your safety goggles! This is very important to protect your eyes.
6. Take one sample of sand and pour one layer of it into a beaker, enough to cover the bottom.
7. Then, suck vinegar into the pipette
8. Squeeze the vinegar out of the pipette and into the beaker with the sand
9. If the sand makes a crackling sound, that means it is biogenic, but if the sand does nothing and is just wet sand, then that means it is detrital.
10. Repeat steps four through eight for the rest of your sand samples

Makena Big Beach

On April 11th we visited both beach spots. There we collected our sand samples and took down our observations. At Oneuli Black Sand Beach, I observed that the beach was small and on the one side of it was a big cliff. The color of the sand was predominantly black but once you looked closer, it was a mix of whites, browns, reds, oranges, and beiges. Much of it resembled the color and texture of the cliff. One other thing about this beach is that the reef are alive, as apposed to Makena Big Beach where the reef was mainly dead. My observations at Big Beach were different. The beach was very big and the sand was very light in color. Just like at Black Sand Beach, Big Beach's sand also has hints of different colors in it. Colors like browns, beiges, whites, oranges, and some specks here and there of black. There was a similar cliff at Big Beach like at Black Sand, but it seemed to be too far away to be causing the sand to be the way it is.

Here are some photos of our sand collecting!

Once we got back into the lab, we tested the sand. When I put some of Big Beach's sand in a beaker and added the vinegar, it bubbled and made a crackling noise. These sensory observations were evidence that this sand was biogenic. Something a little similar but mostly a different experience, was testing the Black Sand Beach's sand. We put it into a beaker and then when we added the vinegar, the sand did not bubble, it was mostly just wet sand. With this, we thought that the sand was detrital, and for the most part it was, but then we started to hear something. It was a very faint crackling sound from the black sand. Although we were confused on what to call it, we came to the conclusion that the Black Sand Beach's sand was in fact detrital with a little part of it being biogenic. 

Although this lab was shorter than they usually are, I really liked it and also learned things that I had not know before. Before, I did not even realize that the beaches were so important and that they undergo some harmful things from constructions and storms. The thing that surprised me the most with this lab was when the Black Sand Beach's sand crackled but did not bubble. I was not expecting that. Some possible sources of error that we DID go through and COULD have gone through to change the results were: putting to much vinegar in the sand, we could have collected the sand in a weird part of the beach in which the sand is not usually like that, and we could have passed by the subtle crackling noise in the Black Sand tester.  

Whale Behavior Observation

A new experiment we are doing in science class is observing whales. We are to observe everything about them such as how far out they are in the ocean, how many their are, how many adults and how many calfs, their behaviors in the waters, and other things observed. Each person in the class made their own research question and hypothesis that they would like to test out.

The information that I would like to know about was how the whales behaved. My question was this:

Is there more whale activity at the beginning of the season or the end?

My hypothesis that I have created was that I think the whales will be more active towards the end of the whale season because they will naturally get more familiar with the area they are living/swimming in. Also, there will be newborns that will probably feel "shy" and getting to know their habitat, and I feel they will become more knowledgeable and comfortable towards the end of the season.

The first chance I got to observe and test this hypothesis was at McGregor's Point. At this spot, we collected our first data. I thought that there was going to be more activity from the whales, honestly. It was okay though because I did see a lot of spouts, dives, and one (sort of) breach! Out in the ocean I looked at mothers and calfs together, along with males in groups of a bunch of whales. I looked through the clinometer my partner and I made to locate the angle at which the whales were and they were normally within the 80 to 90 degrees. I saw that the whales were also moving within a southeast direction. My favorite part about this experience was noticing all the different whales and seeing sea turtles, along with a mantaray out in the water. The most challenging part about this spot was finding the correct angle when we used our clinometer. It kept showing our whales at 90 degrees but we knew that it was not an accurate answer so we had to keep trying. Observing from this point, to me, wasn't THE best but it was a very cool starting point! I cannot wait till we can observe the whales on our whale watch!

Here are the pictures from our first watch!

This is the lighthouse or watchtower at McGreggors Point.

Hard to see, but it is a whale and a spout.

Determining the angle and then the distance of the whales using the clinometer is not hard, just follow this procedure:

1. Spot your whale (Picture three above).
2. Once spotted, look through the eyepiece on the top of the clinometer straight at the whale. Do not move. Let a partner look at the angle shown on your clinometer by the string and weight (As seen in picture two above).
3. Write record the angle. You will need it in order to determine the distance of the whale (s). 
4. Next, find on your GPS the height of elevation at which you currently are at when spotting the whale. Write it down. 
5. Now, plug in your answers into this formula: Distance= Elevation x Tan(Degrees). There you will get your distance.
• For Example:
• If you have 85 degrees as your angle on your clinometer, and the GPS shows your height at 100 feet, your equation would look like this: Distance= 100ft x tan(85)
• Calculate it, and your answer would be: Distance= 1143.0 Feet (away from you)

On the 2nd of March 2011, we went on our second observation adventure, a whale watch! This gave me plenty of whales to observe and the range of activity was way better than McGregor’s Point. This data helped me conclude and put the two data's together creating this graph:

This graph is showing how the whale activity observed was greater towards the end of the season (March) than it was in the beginning. The levels represent their activity with one being the lowest like swimming, spouting, and diving and going all the way up to level four activity which is breaching.

The possible sources of error that I could have come across in this experience was: the incorrect correlation of pod types, direction of travel, time being inaccurate, how we were at two different data points, one we were going to the whales, other we were trying to find them. 

Here are some pictures from the whale watch!

Looking back on the whale watch I remember that it was a great experience. I liked how we actually go out to study the animals up close and also had a guide with us as well. There were many whales to observe and many activities. It was really neat way to learn more about whales.
