of the living labs theory in the 20th century. He suggested that a living lab “represents a user-centric research methodology for sensing‚ prototyping‚ validating and refining complex solutions in multiple and evolving real life contexts” (Bergvall-Kareborn‚ et al. 2009). The living lab approach later on spread from the USA to other parts of Europe‚ and also to developing countries like South Korea and Taiwan. Presently‚ there are numerous descriptions and definitions of living labs from various sources

Design lab for the rate of reaction between Mg and H2SO4 Introduction: Increasing the concentration (in moles) of H2SO4 will increase the rate of the reaction when a ribbon of Mg is added to the solution. The rate of the reaction all depends on how strong the concentration of the solution is. Research question: Does altering the concentration of H2SO4 increase the rate of reaction when a ribbon of Mg is mixed with the solution? Variables: Independent Variable: The concentration of

Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship

INDUSTRIAL DESIGN Product Design Industrial design is the use of both applied art and science to create and develop products that benefit both the user and manufacture. Industrial designers also known as Product designers prepare drawings and illustrations of products that assist in the decision making process. Once the decisions have been made they then prepare the models or prototypes to be demonstrated or tested. However products such as textiles and furniture have designers who specialise

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However‚ some substances‚ such as ytterbium sulfate‚ do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges‚ if no energy enters or leaves the system‚ the potential energy of the state will always be less than that of the initial state”

Lab Report The effect of temperature on the reaction between Catalase and H2O2 Sarah AlShemesi In this experiment we’ll be exploring the effects of temperature on the reaction between Catalase and H2O2.We’ll be using five different temperatures to test this. The five different temperatures will be 10‚ 30‚ 50‚ 70 and 90 oC. We will use the liver as a source of Catalase. A 1 gram piece of liver will be inserted into a test tube with 2 cm3 of water‚ then 2 cm3 of H2O2 will be added. The Catalase

Investigating the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed
