tablets. In the experiment they first tested how long an Alka-Seltzer tablet would dissolve in cold water ( 9 degrees) then repeated it two more times in order to calculate a mean. Then using a hot plate to heat the water‚ they tested another tablet in the hot water (51 degrees) to see how long it would take to dissolve and again did it two more times to calculate a mean. Finally they tested another tablet in water left on the hot plate for thirty-seconds (81 degrees)‚ preformed the experiment for two more

Measurements Lab Report Measurements Cassandra M. Murphy Grand Canyon University: Physics 1 Lab September 5‚ 2013 Testable Question: Circular objects; what happens to the circumference as the diameter changes? Hypothesis: As the diameter increases‚ the circumference will increase in a proportional linear way. This is because as the diameter increase‚ the object will as well. Variables: Independent- The diameter of the circular objects. Dependent- The circumference of the

Purpose: We are doing this experiment to find the best ratio of potassium nitrate to powdered sugar for a model rocket motor that will create the most thrust. We are also testing if adding fins will affect the flight distance of the rocket. Hypothesis: The best ratio for potassium nitrate to powdered sugar is 1 to 3 because Grant Thompson‚ who has experimented with the best ratio of powdered sugar to potassium nitrate‚ has stated that “The 1 to 3 ratio is best for creating the most amount of thrust

Abstract: This experiment will determine if jumping beans are alive. We tested two groups. Group A and B. We put them in two different areas. Three beans were put in a lit area and three were put in a shaded area. It was found that if the depending on how lit the area is the more movement we saw from the jumping bean. Therefore it can be said that jumping beans are alive and respond to stimuli. Introduction: This Experiment “ Mexican Jumping Beans” focuses on how jumping beans respond to different

PHYSICS OF THE PAST One hundred years ago‚ in a poky apartment in Bern‚ Switzerland‚ Albert Einstein‚ then just a 26-year-old patent office clerk still working part-time towards his PhD‚ published five ground breaking scientific papers. Each of these papers‚ written during Einstein’s annus mirabilis ‚ has become a "classic" in the history of science: On a Heuristic Viewpoint Concerning the Production and Transformation of Light ‚ which discusses optical photons and photoelectric effects.

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

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

Introduction. Friction was studied in this lab. The experiments were conducted using a clipboard glued to various surfaces with diffirentiating frictional properties. In order for us to test the varying Static friction or Kinetic friction we used a Newton force gauge‚ some wooden blocks‚ and a metal weight. The actual experiment consisted of two parts. The first part measured the net force‚ or more specific the net force required to overcome the kinetic friction coefficient‚ to move the block across
