Beach Profile!

1. Collect all of your materials.
2. Go to your beginning point.
3. Record the date and the names of your team members on to the data sheet.
4. Place the end of the transect tape on the anchor point and extend tape to the foot of the beach.
5. Turn on GPS device and record beginning point coordinates on data sheet.
6. Record the directional reading of the compass on to the data sheet.
7. Weather the beach is gaining vertical height or losing it over the next meter place the rise pole on the higher point and the run pole on the lower point.
8. Make sure both poles are level and a meter apart using the horizontal portion of the run pole. If for some reason, there is not enough room for the poles to be a meter apart then make them as far apart as appropriate and record distance change on data sheet.
9. Record intersect point on the rise pole on appropriate section of data sheet.
10. Repeat steps 6 through 8 moving one meter closer to the beach each time, do so until the foot of the beach.
11. un-hook transect tape from anchor point, turn the handle of the transect tape and retract it.

Beach Sand Source Lab!

Introduction: For this Lab, we are experimenting different beach sand. We are taking samples from the beaches that we chose, and test them out. Once we have our samples, we will be testing them with vinegar to see how they react. Question: How will Black Sand Beach, and Big Beach's Sand react to the Vinegar in this experiment? Will they react the same, Or different? Latitude and Longitude Of six different Beaches I chose:

• Black Sand Beach-19.36N 155.504W


• Hookipa-205600N 1562127W


• Puu olai-205600N 1562646W


• Kapalua Bay-205958N 156400W


• Oneloa Bay-21017N 1563931W

Black Sand Beach Hypothesis: I think that the sand on Black Sand beach is detrital because of the black rocks from la Parous, and the red sand from the red dirt cliff.

I don't think that Black Sand beaches sand will have much of a reaction to the vinegar because of the more rocky, dirt texture.

Big Beach Hypothesis: I think that Big Beach sand is detrital because of the reef, and predominant from the current moving sand there from another Island. I think that Big Beaches sand will have more of a reaction to the vinegar because of the more blended, smaller texture. Prediction: I predict that the two beaches will react very differently. Materials:

• Van


• Cups


• Journal


• Pen


• Vinegar

Procedure: We picked a few beaches that we wanted to experiment, and researched them to find their Latitude and Longitude. We went to two beaches we chose to get samples, take pictures, and collect data. With all the information that we learned, we started to write our information down to get ready to write our Lab.

Conclusion: My Hypothesis for Black Sand beach was correct. We took a sample of the sand, and added Vinegar; there was a minimal reaction because there is some specs of predominant sand, but most of the sand is detrital. My Hypothesis for Big Beach was also correct. We sampled the sand with Vinegar, and it made a full on reaction.

Whale Observation

The purpose of our whaling observation is to find the distance from where you are to a whale. We use Clinometer.
Does a Clinometer really work to find the distance?
I think it does because, the angle you point the Clinometer brings the weight to the accurate distance.
I thought it was cool testing out the Clinometers and finding whales. My favorite part was spotting the whales and testing out our tool. According to our data, we had no challenges. The post we saw was whales spouting. Their were a few pods of male whales that we saw fighting for the attention of a female. We also saw a mom and calf.

Tide pools

We went to the tide pools and searched for different types of creatures that we normally do not see everyday. We used certain tools to keep track of areas, and where we find these creatures. We were searching for these specific creatures:
Porifera-Sponges, feeders, Multicellular, sessile, fiter
Cnidarians-Jellyfish, sea anemores, corals
Platyhelminthes-flat worms, round worms, Nematoda
Mllusks- Gastropods
Annelids-Annelids, Segmented animals/worms
Arthropods
Arachnids-Insects
Crustaceans-Shrimp, lobsters, crabs
Echinoderms-Sea stars
Pipipi-Sea snails
We mostly found pipipi's.

Geocaching

Geocaching

Geocaching is using a GPS to find Geocaches. Geocaches are basically hidden boxes filled with little goodies and paper to sign who found it.

I learned about the GPS and how to find these Geocaches.

I found one Geocache, and my group total found three the last time we went out. It was a lot of fun, and we get Ice cream for reaching our goals finding three in one class period. :)

Chromatograpghy

What is it? Chromatography is a method for analyzing complex mixtures (such as ink) by separating them into the chemicals from which they are made. Chromatography is used to separate and identify all sorts of substances in police work. Drugs from narcotics to aspirin can be identified in urine and blood samples, often with the aid of chromatography.

<------ Materials

How does it work? A mixture of various components enters a chromatography process, and the different components are flushed through the system at different rates. These differential rates of migration as the mixture moves over adsorptive materials provide separation. Repeated sorption/desorption acts that take place during the movement of the sample over the stationary bed determine the rates. The smaller the affinity a molecule has for the stationary phase, the shorter the time spent in a column.

What is the purpose of using it? In any chemical or bioprocessing industry, the need to separate and purify a product from a complex mixture is a necessary and important step in the production line. Today, there exists a wide market of methods in which industries can accomplish these goals. Chromatography is a special separation process for a multitude of reasons. First of all, it can separate complex mixtures with great precision. Even very similar components, such as proteins that may only vary by a single amino acid, can be separated with chromatography. In fact, chromatography can purify basically any soluble or volatile substance if the right adsorbent material, carrier fluid, and operating conditions are employed. Second, chromatography can be used to separate delicate products since the conditions under which it is performed are not typically severe. For these reasons, chromatography is quite well suited to a variety of uses in the field of biotechnology, such as separating mixtures of proteins.

Whats happening? Because molecules in ink and other mixtures have different characteristics (such as size and solubility), they travel at different speeds when pulled along a piece of paper by a solvent (in this case, water). For example, black ink contains several colours. When the water flows through a word written in black, the molecules of each one of the colours behave differently, resulting in a sort of “rainbow” effect.

Many common inks are water soluble and spread apart into the component dyes using water as a solvent. If the ink you are testing does not spread out using water, it may be “permanent” ink. In such cases, you will have to use a different solvent such as rubbing alcohol.

When Was this first used or invented? This was invented in the early 1900s.

Who first used or invented this technique? Mikhail Semyonovic was the inventor.
