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

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).

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.

Investigation Followup PROCEDURE The purpose of this experiment is to test different minerals to see where on the Mohs hardness scale they would fit. My question and problem‚ “What mineral is the hardest out of all?” My hypothesis is by looking at all mine minerals‚ amethyst is the hardest mineral‚ followed by opal‚ than apatite‚ then halite‚ than graphite and the muscovite will be the softest mineral. To begin this experiment‚ I purchased and gathered all my materials
