Using material from Item B and elsewhere‚ assess the strengths and limitations of using written questionnaires for investigating pupils’ career aspirations (20 marks) A questionnaire is a set list of questions. Positivists see questionnaires as useful because they produce statistical data which correlations and cause and effect relationships can be drawn. Positivists in particular see questionnaires because they produce statistical data from which correlations and cause and effects relationships

Investigating arteries and veins Methodology 1. Suspend a ring of artery from a hook on a clamp stand. 2. Use a metre rule to record the length of the ring once the mass carrier has been attached to the free end of the ring. 3. Attach a 10 g mass and record the length of the ring after the mass is added. 4. Remove the mass and record the length of the ring. 5. Repeat steps 2 and 3 using 20‚ 30‚ 40 and 50 g masses. Record the length with and without the masses each time. When comparing

Tiffany Parker Mr. Taylor Biology 6th period 2/12/15 Gummy Bear Osmosis Lab Report Purpose: The purpose of this lab is to measure the amount of Osmosis in different types of solutions and to see how a cell would react in different types of solutions. Hypothesis: My hypothesis for this experiment is that the Gummy bear will absorb more of the plain tap and sugar water and the salt water will shrink the gummy Procedure: Materials- 3 clear cups‚ one spoon‚ 3 gummy bears‚ timer‚ tap water‚ salt‚ sugar

An investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions

Experiment for the measurement of carbon dioxide and oxygen concentrations and their functions during the act of breathing. Introduction: Humans‚ like all living organisms need‚ O2 in order to live‚ they take the necessary O2 from the atmospheric air. The O2 is transferred from the blood to all cells of the body and serves for oxidation of nutrients for example glucose. By oxidize the nutrients released energy‚ which is necessary for the functions of the human body. During oxidation produces
