Photosynthesis Lab
Introduction To survive, all organisms need energy. Plants get most of their energy from photosynthesis. Plants are autotrophs, that generate their own chemical energy from the product of the sun through photosynthesis. The chemical energy that plants get from the sun is used to produce glucose that can be burned in mitochondria to make ATP, which is then used to drive all the energy-requiring processes in the plant. Photosynthesis occurs in plants in the chloroplast,

Physics Lab Report
ABSTRACT The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment, one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2, which is consistent
