gas causing bubbles to form. These bubbles cause the felt to rise. Problem In this experiment we measured how long it took for the piece of felt soaked in a yeast solution to sink and rise in the test tube. The amount of time it takes for the felt to sink and rise indicates how oxygen bubbles are formed‚ as hydrogen peroxide is broken down. Hypothesis The amount of hydrogen peroxide directly influences the amount of time it takes to break down the yeast resulting in “tiny bubbles”‚ and the

The third experiment followed a 4×4×3 within-subjects design with the following factors: Blocks (4 blocks to test learning effect)‚ Technique (Ray-Casting Selection with visual feedback‚ Bubble Cursor‚ Expanding Target‚ Sticky Ray)‚ Number of Distractors (5‚ 10‚ 15). As there were 9 (3×3 grid) different locations for each condition and we had twelve participants‚ a total of 5184 (4×4×3×9×12) trails were logged. As with the previous experiments‚ by removing 31 trails (~0.5%) as the outliers‚ we were

Basic Concepts of Error Analysis 1. Significant Figures: The laboratory usually involves measurements of several physical quantities such as length‚ mass‚ time‚ voltage and current. The values of these quantities should be presented in terms of Significant Figures as follows. For example‚ the location of the arrow is to be determined in Fig. 1. It is obvious that the location is between 1 cm and 2 cm. The correct way to express this location is to make one more estimate based on your intuition
