Investigating Why Younger People Supported the Nazis Young people supported the Nazis because of the excitement and activities. However there were other reasons, which attracted young people into supporting the Nazis, I will explain these in my essay. I agree with the statement 'the most important reason why young people supported the Nazis was the excitement and the activities'. The youths took part in many activities such as marching, signalling, fixing bikes, collecting scrap metal

The factor I will be investigating is concentration
Investigating Rates of Reactions My aim is to investigate what factors affect the rate of reaction between magnesium and hydrochloric acid. The factor that I will be focusing on is the concentration of Hydrochloric acid. [IMAGE]Reaction Equation: Mg (s) +2HCl (aq) = MgCl2 (aq) +H2 (g) Magnesium + Hydrochloric Acid = Magnesium Chloride + Hydrogen There are several different variables you can such as temperature, concentration; surface area and whether or not to use a catalyst or not
Investigating Factors Affecting the Heat of Combustion of Alcohols PLANNING SECTION Introduction ------------ Alcohols are organic substances, and consist of Hydrogen, Oxygen and Carbon. All alcohols are toxic but the amount that can be tolerated by the human body varies for different alcohols. For example drinking small amounts of Methanol can lead to blindness and even death. Ethanol is the only alcohol that can be drunk safely and is found in all alcoholic drinks. Throughout this
Investigating Factors that Affect the Rate of Photosynthesis in Elodea Aim: To find out which factors affect the rate of photosynthesis in Elodea. Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast
Investigating Photosynthesis in Canadian Pondweed Aim The aim of the investigation is find out what factors affect the rate of photosynthesis. Photosynthesis should not occur if one of the limiting factors is not present. Plan ==== The factors affecting photosynthesis are: Light - This will affect photosynthesis because it is one of the limiting factors. Without light photosynthesis can't take place as it is the energy source. Temperature

Investigating Factors that Affect Heat Loss PROBLEM ======= I have been asked to investigate the link between colour and heat loss. Does the silver or the black cup lose its heat faster? HYPOTHESIS ========== I think that the black cup will lose heat faster than the silver cup because black absorbs heat, then releasing it out of the cup into the surrounding air and surface, where as the silver cup will reflect the heat back into the cup therefore keeping the water hotter for
Investigating Factors Affecting Resistance of a Wire Aim --- Investigate what factors affect the resistance of wire, however in this experiment I am going to monitor how the length of a wire affects the resistance of a wire if the current is kept the same. Method ------ 1) Arrange apparatus as shown in the Diagram: 2) Cut a length of wire over a meter long and sellotape to a meter ruler. 3) Attach one positive crocodile clip to 0cm, and move the negative up/down, stopping
Investigating Osmosis in Potato Chips Planning Introduction: the definition of osmosis is the movement of water particles from a weaker solution to a stronger solution through a partially permeable membrane. Aim of investigation: I am trying to find out how external concentration of liquid surrounding a potato chip affects it - does it increase or decrease in mass etc. Method, diagram and equipment: Diagram of experiment Equipment · 5 Boiling tubes · weighing scales
Investigating Osmosis in Potato Tissue Aim-We are going to investigate how 'osmosis' is effected by higher and lower concentrations of water using potato cylinders as selectively permeable membranes. A selectively permeable membrane is something only water molecules can pass through. We will cut eighteen potato cylinders to the same width and length using a scalpel and a corer on a white tile. We shall use the same potato for each cylinder. The cylinders should then be around the same
Investigating Factors Which Affect The Reaction Between Chalk and An Acid Introduction: Chalk is just one of many forms that calcium carbonate can take. It is made of the mineral remains of sea creatures from millions of years ago. It is quite soft, but solid. It reacts with hydrochloric acid like this 2 CaCO3 + 2 HCl → CO2 + CaCl2 + H2O producing Carbon Dioxide, which is what we measure in the experiment. There are different factors affecting the rate of this reaction, such
Investigating Osmosis In A Potato Introduction: "Osmosis is typically defines as the flow of one constituent of a solution through a membrane while the other constituents are blocked and unable to pass through the membrane. Experimentation is necessary to determine which membranes permit selective flow, or osmosis, because not all membranes act in this way. Many membranes allow all or none of the constituents of a solution to pass through; only a few allow a selective flow. In a classic
Investigating Factors that Affect the Swinging Of a Pendulum Aim Our aim is to find out whether changing the variables of the swinging pendulum affects the speed. Preliminary Work In order to find out which variable/s affect the swinging of a pendulum, I need to test all the variables available.
