2009-03-08T13:57:00.001-07:00

While there was free time at school, the researcher was thinking of a topic for her mathematical investigation. At that time, a classmate and friend of hers approached her and the researcher asked her about the classmate’s project which is an extension of a former mathematical investigation. From that, the investigator thought of another focus which this project tackles.

Problem
What general equation will be formed that can represent the number of line segments which can be formed by connecting equal number of points on the sides of a regular polyhedron?

Field
Geometry

Purpose
To formulate an equation that gives the number of line segments which can be formed by connecting equal number of points on the sides of a regular polyhedron.

There is already a formula in getting the number of diagonals of faces of polygons and of skewed vertices of polyhedrons. However, the researcher thought of a way to join both without using these two formulas so the investigator thought of this problem, applying it to regular polyhedra.

Date Started
March 4, 2009

Target
The target of this project is to make a formula for all nine regular polyhedra.

Problem
What is the effect of Ipomea batatas leaves on the mitotic activity of sea urchin cells?

Field
Biology

Purpose
The field of Medicine has always been in constant search for a cheap and readily available cure or prophylactic cure for cancer.

Ipomea batatas (Camote) is a known staple food and the edible parts are the tuber and the young leaves or tops. Being a green leafy vegetable, the tops are full or nutritious elements good for the body. But what if, aside from its nutritive value, it also has some medicinal properties, particularly anti-cancer?

The research is a preliminary study to determine the anti-cancer effect of Ipomea batatas leaves by studying its amitotic ability on sea urchin cells. By identifying its amitotic effects, one can surmise that camote tops may have some anti-cancer properties which may prove another advantage to its intake.

After defeating the Blue Vaio, Red Macintosh defeated the Yellow Asus in Sepak Takraw Girls Championship Game.

Although junior player Alpha Colocado suffered a sprain since the day before, she together with Karen Vie San Juan and Isidra Cruto won over the Yellow Asus players not only once, but twice.

After winning against seniors, the red team proceeded to the game against the yellow team. Since the sophomores haven't lost in any game, the juniors needed to beat them two times. In both cases, the Macintosh turned out victorious.

Cheerers from both teams roared out their yells to boost the spirits of the Sepak players.

Though many of the points of each team came from faults in service, both teams still showed skill and determination. Truly, their perseverance in practicing gave the teams a great advantage over others.

GO MACINTOSH!!!

One of the games of the second day of the sports fest was volleyball, where girls from Green Acers and Red Macintosh faced with each other.

This happened exactly after the basketball game of the same teams, where some of ithe red team's players were also players for volleyball. With this fact, no wonder some of the best volleyball players said they were not in the condition to play.

After three sets of rallying between the two teams, the freshmen emerged victorious. This was the time when Helen, a first year student, started to get famous, with volleys hard to return.

The same day, the female Acers were also able to defeat the other two teams in volleyball. Unbelievable? No. Amazing? Yes!

Macintosh volleyball players will stand up once more!

With grace and perseverance, CNSHS students began the intramurals with the cheer dance competition. Showcasing different steps and grooves, the audience roared with excitement as each team presented the performance they all worked hard for.

With every movement, CNSHSians watched with enthusiasm as they saw their schoolmates dance with much vigor. Even the guests of the day were taken aback by the energy given off by the cheer dancers.

Smiling through every cheer, yell and song, the dancers were not only able to entertain the other students, teachers, and guests but also lift up the spirits of the players who will play in the following days of the sports fest.

The whole school shook with anticipation as the results of the winners were announced. What came up was that the Green Acers was fourth, Yellow Asus was third, Blue Vaio was second and Red Macintosh was first!

Though there were some who shouted pull-downers, the champions for this event continued to celebrate their victory.

Great start Red Macintosh!!!

Their inspirations in making their research is common, like their family. Though it was like this, they are pretty good since they get interested in fields and become passionate for it. It inspires me that there are people who are like that. Hopefully, when the time comes, I become like them, using their passion in order to do good to our country. It is also amazing that these people have wonderful ideas in mind which are relevant to our country's present condition.

Background: Drafting in cetaceans is defined as the transfer of forces between individuals without actual physical contact between them. This behavior has long been surmised to explain how young dolphin calves keep up with their rapidly moving mothers. It has recently been observed that a significant number of calves become permanently separated from their mothers during chases by tuna vessels. A study of the hydrodynamics of drafting, initiated in the hope of understanding the mechanisms causing the separation of mothers and calves during fishing-related activities, is reported here.

Results: Quantitative results are shown for the forces and moments around a pair of unequally sized dolphin-like slender bodies. These include two major effects. First, the so-called Bernoulli suction, which stems from the fact that the local pressure drops in areas of high speed, results in an attractive force between mother and calf. Second is the displacement effect, in which the motion of the mother causes the water in front to move forwards and radially outwards, and water behind the body to move forwards to replace the animal's mass. Thus, the calf can gain a 'free ride' in the forward-moving areas. Utilizing these effects, the neonate can gain up to 90% of the thrust needed to move alongside the mother at speeds of up to 2.4 m/s. A comparison with observations of eastern spinner dolphins (Stenella longirostris) is presented, showing savings of up to 60% in the thrust that calves require if they are to keep up with their mothers.

Conclusions: A theoretical analysis, backed by observations of free-swimming dolphin schools, indicates that hydrodynamic interactions with mothers play an important role in enabling dolphin calves to keep up with rapidly moving adult school members.

Give a sample problem and state the problem, objective, materials, and the procedure (enclosed are the controlled and experimental conditions; controlled - bold, experimental - italicized)

Problem: What is the effect of playing rock and classical to the growth of mongo plants?

Objective: To determine the effect of different kinds of music (rock and classical) to the growth of mongo plants.

Materials: pots, mongo seeds, cassette/cd players, tapes/cds of rock and classical, water, soil

Procedure: Fill three pots of the same size with the same amount and kind of soil and plant five mongo seeds each in them. Place the three pots in a place with enough and equal amount of sunlight for each and water each plant with the same amount of water. Place one pot with the player playing the classical music, one with the rock music and one without any music. Observe each plant everyday and record the findings.
