RESULTS Aphid survival experiment Aphid survival rate varied with both of different combinations of predators-aphids and various times in presence or absence of ants (Table 2). GLM results showed that the interaction of ‘time × different combinations of predators and aphids × ant’ (F = 0.211; df = 10‚ 317; P = 0.995)‚ ‘ant × time’ (F = 0.490; df = 2‚ 317; P = 0.613) and ‘different combinations of predators and aphids × time’ (F = 1.639; df = 10‚ 317; P = 0.095) on the survival rate were not significant

For this experiment‚ we started off by taking tubes numbered 1-4 and started adding one scoop of our enzyme catalyst‚ in this case‚ the yeast. We then proceeded to measure and add 1 mL of distilled water to test tubes A-D. To get a more accurate measure of 1 mL of distilled water‚ we used the dropper labeled “W” to drop distilled water into the 5 mL graduated cylinder until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and

submitted: 5/29/13 ELECTRIC FIELD MAPPING I. ABSTRACT: In the Electric Field Mapping‚ we used charged electrodes to create an electric field on a glass tray with a piece of linear graph paper attached to the bottom. We tested several simple electrode positions by moving the probes and drew equipotential lines based on the voltage difference. We then confirmed that the equipotential lines run perpendicular to electric field lines by looking at the experimental data points. Lab Partner: Matthew Seesselberg

Abstract: Theoretically‚ this experiment is used to address the Newton’s Second Law of Motion which is the net force is product of the mass and the acceleration of the object. However‚ the performance’s result would be measured acceleration instead the net force. During this experiment‚ the objects are two weight hangers with a same origin mass which is 5g and later have total mass is around 2000g. The experiment is performed by transferring mass from one to another hanger and calculates the

Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found evidence that magnetic field lines go from a north magnetic pole to a south
