Acceleration Lab Report
Xuan Ho November 9, 2015 Force on an Incline/Newton’s Third Law Lab Introduction Acceleration is defined as the rate of change in velocity of an object. When combined with a ramp, patterns can be concluded. The angle of an incline is a very influential factor when determining acceleration. For example, if the incline was of a small angle, an object being rolled down will be slower and could be easily timed. However, if the incline

Glowing Bacteria Lab
Bio 11H lab Introduction: In this lab we are going to make protein glow by bacterial transformation. Bacterial transformation is done by inserting DNA into bacteria where it will replicate. It uses an inducible promoter to regulate gene expression. We used a special RNA Polymerase (T7) which is controlled by the LAC promoter. Without the T7 polymerase glowing proteins could not be expressed. Normally the Lac repressor is activated making the glowing proteins non expressible.

Solubility Product Constant Lab
Introduction: When a salt of low solubility is added to water, only a few ions are formed, and most of the salt remains undissolved. In a saturated solution, the solid dissociates into ions at the same rate that the ions reunite to form the solid. In other words, a dynamic equilibrium exists between the undissolved solid and the ions in solution. An undetermined amount of dissolved salt exists in equilibrium with the solid. The concentration
