Mathematical Investigation: VON KOCH’S SNOWFLAKE CURVE Ha Yeon Lee 11B Mathematics HL • Introduction: ➢ History of Von Koch’s Snowflake Curve The Koch snowflake is a mathematical curve‚ which is believed to be one of the earliest fractal curves with description. In 1904‚ a Swedish mathematician‚ Helge von Koch introduced the construction of the Koch curve on his paper called‚ “On a continuous curve without tangents‚ constructible from elementary geometry”

cellular respiration is taking place at the same time‚ consuming oxygen‚ the rate of which the discs rise is an indirect measurement of the net rate of photosynthesis. Aim: To find out if light affects the rate of photosynthesis through an investigation with leaf discs of a spinach leaf. Hypothesis: If the light source is removed or becomes limited‚ then it will take much longer for the leaf disc to rise as cellular respiration will no longer be taking place as part of the equation for photosynthesis

Genes and Genetics 1. 2. each chromosome exists as two genetically identical chromatids attached to their centromere. Each chromosome appears as two chromatids attached to a centromere. In the first meiotic division chromosomes align in homologous pairs. Points of contact form between members of the same homologous pair. The points of contact or crossing over between members of a homologous pair are the chiasmata. 3. The homologous pairs move to the equator of the cell. Equal lengths of the

Serial Arsonist Conducting an arson investigation is a straightforward affair. The first thing to do is determine if the crime committed was actually arson‚ as arson has a strict definition. This can be especially difficult if the arsonist is skilled at his craft‚ and assume it’s a he because 94% of arsonists are young males (Baker‚ 2005). After investigating the scene and determining it was an arson‚ the next step is to determine what kind of arson it was‚ mass arson‚ serial arson‚ or spree arson

Historical and Biographical Approaches Historical criticism seeks to interpret the work of literature through understanding the times and culture in which the work was written. The historical critic is more interested in the meaning that the literary work had for its own time than in the meaning the work might have today. For example‚ while some critics might interpret existential themes in Shakespeare’s Hamlet‚ a historical critic would be more interested in analyzing the play within the context

these results as I believe the more Magnesium there is the more Oxygen it will take on to form the Magnesium Oxide and so believe the results should gradually get heavier and heavier as the Magnesium gets heavier and heavier. The equation for this investigation would be Mg + O2 MgO which would balance as 2Mg + O2 2MgO. This is done as the Oxygen has two molecules which would need two Magnesium molecules to balance it out.
