Squid Experiment

1. Move the lid of the container up or down. Record the resulting volume and pressure

Around the mouth of the octopus are eight arms. The eight arms allow the octopus to move, crawl, and swim around in its habitat. Octopuses crawl slowly, walking on its arms to move through the water headfirst with the arms trailing behind. When necessary, octopuses can move fast using their arms to propel it through the water similar to jet propulsion. The suckers found

the stopcock to release the pressure. Close the stopcock, shake the funnel several times, and again release the pressure through the stopcock (see Technique 12, Section

What does it eat? It primarily feeds on algae. Its spines and tube feet help it to grab food.

During the day, the squid bury itself in sand or muddy area near sea grass beds. Besides that, it forms camouflage by gluing sand grain to its body. Night, they emerge to feed. A type of bioluminescence sea creature. It will emit light from their ventral surface. The light emitted is adjusted to match the intensity of moonlight. Collaboration of Hawaiian bobtail squid's eyes and extraocular vesicle use to monitor the down-welling light via silhouette reduction. This behaviour called as counter-illumination. Thus, the squid can adjust the intensity of bioluminescence as it moves to various depth by modifying the ink sac, which function as a diaphragm around the

Vampire squids can use bioluminescent bacteria to protect itself from predators by confusing them with lights shining in different direction so they are unable to locate where the creature is exactly. These bioluminescence can also be used to see slightly better in the very dark or locate other of its kind to communicate with. Some other animal with unique defense methods include armadillos, which roll up into a ball protecting themselves with their hard outside, or even skunks, that will spray any predators with noxious musk to defend themselves.

In 2004, the giant squid had been discovered in deep, inky waters (Schembri 1). These creatures had frequently been misconstrued as monsters throughout history, in sailors’ yarns, wives tales, and even official reports. With a length of 40 to 42 feet, the leap of faith does not seem so difficult. (Giant 1) Giant squids are not known anymore to sink ships like their Kraken persona, but they are extremely territorial, even fighting sperm whales to protect their homes (Coppens 4). Despite being capable of eating just about anything with meat on it, Giant Squids mainly feed on small fish and clams (Schembri 1). For millennia, the giant squid lived in the realm of legends. Its existence lied in the study of cryptozoology, or “the pursuit of wildlife

Dysticus, the diving beetle, carries a bubble of air with them when they dive beneath the water surface. This bubble of air can be trapped under the wing covers and usually covers one or more spiracles so that the insect can breathe the air from the bubble while submerged in the water. This trapped air acts as a diffusion gill and the oxygen diffuses into it from the water and then into the tracheae. The concentration gradient for the diffusion of oxygen is maintained by metabolism in the tissues. This air bubble provides the diving beetle with a short-term supply of oxygen but due to unique physical properties, the bubble can collect some oxygen molecules that has dissolved in the surrounding water. This system works more efficiently when the bubble has a larger surface area. The diving beetle can remain submerged in the water as long as the volume of oxygen diffusing into the bubble is greater or equal to the volume of oxygen that

As larvae, these animals use cilia to move themselves through the water. Most of their travels however are dictated by the ocean currents. They literally “go with the flow.” When they do move on their own, it is usually to be near the surface of the water. They do this by propelling themselves through the water. The base of the bells is lined with muscles that contract rhythmically creating a jetlike

Both the orifice and the Venturi meters produce a restriction in the flow and measure the pressure drop across the meter. The velocity of a fluid is expected to increase as the fluid flows from an open area, to a more constricted area. Assuming incompressible flow, a negligible height change, and steady state, Bernoulli’s equation can be simplified to show the correlation between the volumetric flow rate and the pressure drop. The equation for both meters is as follows:

PLTW (Project Lead The Way) is the leading provider of rigorous and innovative Science, Technology, Engineering, and Mathematics education curricular programs used in middle and high schools across the U.S. New Mexico State University’s College of Engineering has served as the NM PLTW Affiliate since 2006. As the state affiliate, NMSU oversees the PLTW Summer Core Teacher Training programs, held specifically to train PLTW teachers from across the state in this highly effective curriculum. NMSU also hosts the annual NM PLTW Teacher Conference each fall. The PI plans to host one training session per year for the teachers to introduce the low-power devices developed in this proposal. The PI also plans to visit the middle school classroom once per year to demo these devices.

Squid and Octopi are two mysterious creatures of the sea which many people lack knowledge of. They both have many amusing similarities and differences when it comes to their homes, diets, and physical aspects. These two sea creatures relate in many ways, however there are countless unique characteristics between them.

The giant squid adapts to its living conditions in many ways. Its prefered habitat is around continental shelves and island slopes, approximately 500-1,000 meters below the surface (Source 1). Giant squids also use their appearance as an adaptation. For example,

The Blue ringed octopus can move several different ways. One way is by drawing water into a cavity in its body, and then dismissing the jet of

First, I will use sandpaper to roughen the end caps of PVC pipes. I will then use the sandpaper to roughen the two opposing sides of three plastic containers by roughening two 1-inch by 1-inch patches across each other. Using permanent markers, a mark will be made in the center of the roughened side of one of the plastic containers. I will use a ruler to measure the location of the mark and then make a mark at exactly the same location on one of the roughened sides of each of the other two plastic containers. The ruler will be used to measure the outer diameter of the aquarium pump tubing. I will then drill a hole 2 millimeters (mm) in diameter on top of three of the plastic container lids. In one of the lids, I will dill another hole the same diameter as the plastic tubing of the aquarium air pump next to the first hole. A hole will be drilled on the permanent marker marks on the sides of the plastic containers using a 3/4 –inch spade drill bits.
