be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source. Beaker #1 is six inches from the light source. Beaker #2 is nine inches from the light source. Beaker #3 is twelve inches from the light source. The dependent variable is the rate of photosynthesis (number of leaf disks floating). There are ten leaf

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate

LABORATORY REPORT ENGINEERING SCIENCE – ENSC 1005 LECTURER: Asha Sooknanan It is important that a student not only learns the physical concepts discussed in a laboratory exercise‚ but that the student also learns how to communicate those ideas effectively. In a technical lab report‚ the results will often be read by engineers‚ engineering technologies‚ and other scientists‚ but also by people in industry who may not have significant training in physics. Due to this fact‚ a technical lab report

Uncertainty is the theme of the whole film " As Prof Gopnik ponders the nearness of death in all our lives‚ the tininess of any one life‚ and the vanishingly small difference between death and life‚ could it be that he is Schrödinger’s Cat‚ both alive and dead?

Though they live in different worlds‚ Bruce Wayne and Harry Potter share uncertainties about their natures in the battle of good vs. evil‚ an uncertainty revealed through each character?s relationship with darkness. Harry?s uncertainty stems from his role in both the muggle and the wizarding world. First‚ Harry is dropped on the Dursley
