“polymer creatures‚” which are the things that are used in experiments about polymers. The polymer creatures‚ made out of two different polymers‚ are both hydrophobic and hydrophilic. This means that while the hydrophilic polymer absorbs water‚ the hydrophobic polymer keeps the shape that the creature was originally in while the water is inside the creature. Another name for this process is osmosis

Objective In this experiment the purpose is to study the period of the pendulum with different masses. Secondly to also study the relationship in the different lengths of the string and how it affects the period. Thirdly to find the different (time) periods in the changes in the arc size. Theory If the pendulum is set ‚ the force of the motion is used to swing back and forth . where the t period is the time the pendulum takes to complete a cycle of oscillation. As t-1/f the complete distance of

right brain‚ researchers created three experiments. The first experiment was created to test visual abilities by transmitting an image of a word‚ picture‚ or parts of a word to only one side of the brain. The second method tested touch; they allowed a participant to touch an object‚ like a block letter‚ without seeing it. The last method tested auditory abilities and consisted of limiting a participant’s response by being told directions.The visual experiments showed that both sides of the brain are

Analysis Torque is the ability of force to change the rotational motion of a particle. It is also called the moment of force. It is always specified with regard to the axis of rotation. On the experiment the axis of rotation serves as the model balance. This means that as much as torque is directly proportional with the force applied on a particle‚ it is also dependent on the perpendicular distance of the applied force to the axis of rotation. On the first activity we need to determine

The stanford prison experiment Assignment #3 Watch the video on the Zimbardo Stanford Prison Experiment available in the Webliography (Quiet Rage http://topdocumentaryfilms.com/quiet-rage-the-stanford-prison-experiment/). In your Threaded Discussion‚ worth 20 pts‚ post your thoughts regarding the following discussion questions excerpted from Zimbardo: 1) Was it ethical to do this study? Was it right to trade the suffering experienced by participants for the knowledge gained by the research

Bouncy Ball Experiment Aim: The aim of this experiment is to investigate the efficiency of a bouncing ball‚ and the factors which affect its efficiency. Prediction I predict that the higher I drop the ball from the higher it will rebound up‚ because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy‚ and then when it hits the ground changes to heat and sound energy‚ and kinetic as it rebounds back up. The higher up

Microbial Growth of Consumable Products By Bryce Wilmott AIM: To calculate the quantity of observable microbial colonies on the surface of the Agar solid‚ as to determine the presence of microbes in consumable products i.e. yoghurt and blue vein cheese. HYPOTHESIS: Microbial growth will be present in two of the three Agar plates (those containing the food product) due to the suspected presence of microbes‚ whilst the control Agar plate (containing no food products)

Discussion: First of all‚ rinse all the apparatus that being used in the experiment with hydrochloric acid (HCL) then followed with distilled water (H₂O). Then‚ prepared the saturated calcium hydroxide (Ca (OH) ₂) solution into a filter funnel and filter paper over a second conical flask. Pour 100.00mL of saturated Ca (OH)₂ solution into a beaker and pour the solution through the filter paper by flowing the solution through a glass rod. After that‚ use a thermometer to measure the temperature of

Introduction: The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount

Change in Precipitation Ramon Pena BIO101 February 14‚ 2011 Dr. Richard Steiner Change in Precipitation Introduction This experiment will take course during a 300-year-time -period simulation. This experiment will consist of two islands‚ Darwin Island‚ Wallace Island and take only into account the bird population of these two islands. The parameter will stay the same‚ except for one variable; precipitation. I will record how the precipitation changes the beak size of the bird population
