"Tide"

Pretest for Week 1

What causes tides? Tides are caused by a pull of gravity of the moon and sun, and by the rotation of the earth, moon, and sun.

What is animal adaptation and why is important to animal survival? Animal adaptation are the phyisical features of an animal. The features may represtent fur, skin, nose, ears, eyes, etc.. Moreover, these features are important for the animals to survive.

What is symbiotic relationship? Symbiotic relationship is different species of plants or animals living together in a mutual advantageous relationship.

What is density? The weight of something for its size.

What are the main causes of currents in the oceans? Ocean currents are caused by the circulation of wind above surface waters.

What is sea floor spreading? Sea floor spreading is the process in which the ocean floor is extended when two plates move apart.

What is biological evolution? Biological evolution is a change in the traits of living organisms over generations including the emergence of new species.

How do scientist classify animals? The classificaion by scientists is usually between two groups known as the vertebrate (with backbone) and the invertebrate (without backbone).

What is scientific method and what are their steps? Scientific method is the process of experimentation that is used to answer questions and explore observations. The steps are as:
STEP 1: Name of Problem or Questions
STEP 2: Hypotheses
STEP 3: Test Hypotheses
STEP 4: Check and Results
STEP 5: Report and Record Results

What are the main zones in Marine Environment?

Tide Week 2

What is tidal range? Tidal range is the vertical distance between high and low tide.

What causes high and low tides? The high and low tide are caused by the gravitational forces between the earth and the moon.

What causes Spring and Neap tides? The cause of Spring tides occurs when the Earth, the Sun, and the Moon are in line. Usually it happens during the full moon and new moon. On the other hand, Neap tides occur when the gravitational forces of the Moon and the Sun are perpendicular to one another. The Neap tides usually occur during the quarter Moons.

How does tidal range effect the types of organisms and the shape and size of the organisms?

"Observing Your World" Week 1

Science is the process of trying to make sense of the world around us. Every culture has its own way of making sense of how the world works. Modern science follows a tradition of asking questions, forming hypothesese, testing the hypothesese through experimentation and recording observations. These observations are compared against the observations of others to see if the results are varifiable or reliable. Most of what we accept as factual in science was ascertained by this process. There are limitations to this world view and there are other ways of coming at the same information or at the very least recognizing patterns in the environment etc. without necessarily knowing why.What are your cultural ways of understanding the world? How do you do science? What conflicts have you faced or contradictions?


There are many explanations and reasons to how people observe their world. However, from my perspective and cultural background as a chamorro, I will share one interesting belief that has and is still being practiced from the good old days to modern society. The "chamorro culture" strongly believes that there are certain plant life that must not be disturb. Some are considered off limits, meaning not bothered, disturbed, or removed. For an example the "Banyan Tree" also known as "Trongkon Nunu" in chamorro, is believed to be the dwelling place of the ancient spirit called or known as the "TaoTao Mona". In english, taotao mona is called the people ahead of us or our ancestors. Moreover, the banyan tree MUST or SHOULD be respected and not disturbed, otherwise, those who disturbs the banyan tree will suffer from some form of illness or bad luck from the ancient spirits.
