TOPIC 6‚ 11‚ & OPTION H: HUMAN HEALTH AND PHYSIOLOGY Digestive System Includes all the structures that are concerned with bringing food into the body to provide for the needs of the body’s cells. Each cell in an organism relies on a continuous expenditure of energy. Fats‚ carbs‚ and proteins are broken down during cellular metabolism and the energy derived from them is used to make ATP. The digestive system deals with: Ingestion‚ which is the bringing of nutrients into the body. Mechanical

Water lab Research Question: How many drops of water can fit on a coin? (Water properties involved are cohesion and surface tension. Cohesion plays a consequential role in the transport of water within plants specifically within the phloem. Surface tension also dictates an important role within the transpirational pull of the xylem.) Variables: Variables | Type of Variable | How it was manipulated | Independent | Water drops‚ different types of water | Determining how many drops of the

Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted

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

ENGLISH HL SHAKESPEARE- MACBETH ESSAY It is human nature to be intrigued by all things mystical and dangerous. We fear the unknown but seek it nonetheless out of greed. Most of Shakespeare’s works hold an element of the supernatural and the play Macbeth is no exception. In this play we see a contemporary morality that warns of the dangers of trafficking with instruments of darkness; the witches in the play prophesize of Macbeths future as king‚ and Macbeth blinded by his hunger for power fails
