Introduction: This experiment was conducted to see which colored light pill bugs would prefer more out of red‚ blue‚ yellow‚ and green lights. If pill bugs went to the green and yellow lights more than the blue and red lights‚ then this means they like brighter lights more than gloomier lights. For the experimental group‚ the colors used were blue‚ red‚ yellow‚ and green. The controlled group was the middle chamber. It got regular light from the classroom. The independent variable was four different

One objective was to figure out if the burnt Mg ashes weigh more than the product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner
