Purpose: The purpose of this lab is to investigate the causes of terminal velocity‚ specifically the relationship between terminal velocity‚ mass‚ and air resistance. Materials: -20 “Giant Cupcake Liners” -3 timers -String -metre stick Procedure: See assignment sheet Results: See assignment sheet for table of values Discussion: 1. Using your graphical analysis techniques‚ straighten out the graph of velocity vs. mass and

filter is linearly related to the height at which the filter is dropped. Concavity‚ weight‚ and surface area was kept constant throughout the experiment. Method: The materials required for this experiment are a tape measure‚ two coffee filters‚ and a timer. Stack the coffee filters. The purpose of this is so that the system is more weighted. Measure the following heights to drop the coffee filters from: 1 ft‚ 2 ft‚ 3ft‚ 4ft‚ 5ft‚ and 6ft. Drop the coffee filters from the respective heights (Figure 1)

The reason I am using one with a cork attached is to keep in as much heat as possible. Timer: I am using the timer to make sure I burn the fuel for the right amount of time Measuring cylinder: I am using the measuring cylinder to measure the water making sure it is the right amount Wooden split: I am using this because it is a safe way of lighting

solution‚ which would result an increase or decrease of catalase activity. A parallax error may have occurred when measuring the amount of foam produced from each reaction‚ which decreased the precision of the results. Due to reaction time when using a timer the exact rate of reaction of the catalase activity cannot be determined. The time the liver reacts with the solution varied with the sample of 3 for each temperature. Because the reaction initiates as soon as the reactants make contact catalase activity

To perform the exercises in this post and see the results‚ you will need a book of 200 pages that can lay flat when open‚ a pen‚ and a timer (a stop watch with alarm or kitchen timer is ideal). You should complete the 20 minutes of exercises in one session. First‚ several definitions and distinctions specific to the reading process A) Synopsis You must minimize the number and duration of fixations per line

Cell Transport Mechanisms and Permeability 1 EXERCISE 1 OBJECTIVES 1. To define the following terms: differential permeability‚ passive and active processes of transport‚ diffusion (simple diffusion‚ facilitated dif- fusion‚ and osmosis)‚ solute pump‚ pinocytosis‚ and phagocytosis. 2. To describe the processes that account for the movement of sub- stances across the plasma membrane‚ and to indicate the driving force for each. 3. To determine which way substances will move passively

speed solvers but not many beginners? The beginner’s method is easy to learn‚ but I hypothesized that the Fridrich method would be the fastest at solving the puzzle cube. To be able to test this question‚ one must have a Rubik’s cube and a puzzle timer. First one has to learn how to solve the puzzle cube in the two methods we talked about‚ then after one knows them by memory time each method 100 times‚ average the times and compare which is the fastest way to solve it. After testing I concluded that

Intro I am going to do an investigation into what concentration of sucrose solution would cause “Incipient Plasmolysis”. Theory Plasmolysis is the result of a (in particular) plant cell which has lost vast amounts of water. When this happens‚ turgor pressure within the cell has decreased to the point where the cytoplasm of the cell membrane peels away from the cell wall. When this begins to happen it is called Incipient Plasmolysis and when the cytoplasm is almost completely gone it is call “full/complete”
