The Bermuda Triangle Conspiracy The Bermuda Triangle is a place that has been seeing sketchy disappearances since Christopher Columbus’ time period. The Triangle is an area in the North Atlantic Ocean between Bermuda‚ Florida‚ and Puerto Rico. The area is occupies is the site of numerous disappearances of people‚ ships‚ and planes. The Bermuda Triangle covers approximately 500‚000 square miles. Aircraft and ships go missing‚ compasses spin wildly‚ strange clouds of fog arise‚ ship and airplane

A small scale investigation into the factors influencing the conceptual change in children’s scientific thinking Abstract The present study aims to compare how Piaget and Vygotsky theories promote conceptual change in children’s scientific thinking. The investigation is an adaptation of a procedure used in 1930 by Piaget and compares two children’s predictions and explanations of why some objects float or sink. Children’s thinking is then challenged using discovery learning and scaffolding

Buoyancy‚ Force‚ and Gravity Purpose: To check the buoyancy of the object measured in Newton. Hypothesis: I think the force pulling down on the clay might be heavier then the container with water and clay. Apparatus: 1 small beaker (mL) 1Graduated cylinder 1 container 1 small portion of clay can Spring scale (newtons) Tap water 1 Cloth Method: First‚ hang the clay on the hook of the Newton spring scale. Secondly‚ record the measurements. Thirdly‚ get a container‚ fill it with

submarine moves forward. The crucial problem for a submarine is that it must either sink or float on command. Most things either sink or float‚ but can’t do both. Why? When an object is placed into water‚ it either sinks or floats according to its density. Objects denser than water (like metal) sink‚ while objects less dense than water (like air-filled balloons) float. What about a submarine? To decend‚ water is pumped into the ballast tanks. To rise‚ air is forced into the ballast tanks‚ pushing

the theoretical stability that was calculated. Theory To find out if the floating body is stable‚ this experiment is to find out the metacentric height‚ height of buoyancy‚ and the gradient of stability. The center of buoyancy must be found by shifting weight on the plastic sail. Using the recorded data to find the center of buoyancy must be lower than the center of gravity for it to be stable. Description of Apparatus A pontoon that has a rectangular form and a plastic sail to be put a container

EVALUATION OF INDIAN TAX STRUCTURE IN PERSPECTIVES OF DTC AND GST AND IDENTIFYING ITS ROLE IN ECONOMY. Abstract: The Indian constitution is quasi-federal and the country has a three-tier government – Central government‚ State Government and Local Governments. As the local public authorities are directly under the state government‚ no separate allocation of taxation rights has been done to them. Rakesh Mohan at the NCAER conference held in January 2004‚ had argued that under-taxation in India

The wild type and the mutant type strains of Halobacteria were used in this experiment to examine the phenotypic differences against each strain’s genotypes. The mutant strain (KBT-1) did not possess gas vesicles‚ which decreased its ability to float to the surface. The lack of gas vesicles in the mutant strain made the colonies a red color. The wild type strain (NRC-1) had gas vesicles and appeared a pink pigment color. Growth on the agar allowed one to examine the specific colonies. Inoculation

Snorkeling (British spelling: snorkelling) is the practice of swimming on or through a body of water while equipped with a diving mask‚ a shaped tube called a snorkel‚ and usually swimfins. Spearfishing is an ancient method of fishing that has been used throughout the world for millennia. Early civilizations were familiar with the custom of spearing fish from rivers and streams using sharpened sticks. Today modern spearfishing makes use of elastic powered spearguns and slings‚ or compressed gas
