In the eye opening documentary‚ The Human Experiment‚ directed by Don Hardy and Dana Nachman‚ the many health dangers of thousands of harmful chemicals in everyday products are exposed. The film explores the lives of people who have been affected by the ubiquitous chemicals found in our food and our homes. The film addresses the battle against powerful industries that are determined to keep consumers in the dark about the dangers of many of their products. The fight against dangerously lethal chemicals

Objective 1. To demonstrate the relationship between the pressure and temperature of saturated steam in equilibrium with water. 2. To determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas

After a holding period of 18 hours for winter captured crabs and a period of 30 hours for summer captured crabs‚ all individuals were transferred to containers with experimental temperature and salinity levels to begin the experiment. To observe changes due to salinity concentrations over the 48-hour period‚ groups of crabs were exposed to one of the eight salinity treatments‚ and temperature treatments were held constant at 5°C or 15°C to resemble winter or summer field conditions

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)

Abraham Lincoln has all the qualities of a great leader‚ it is therefore correct to say he was a catalyst for change‚ since he had tremendous effect on history in his decision making. Till this day after 125 years that he is no longer in this world‚ people are still inspired by him and his leadership skills. Abraham Lincoln can be defined as a catalyst for change due to his concerns‚results-orientation‚courage‚commitment and honesty. Lincoln was successful in becoming the

The testing for the Doll Test OR Eye Color Experiment resonated more with children is because children are brought up in discrimination house hold. Doll test told that how equal size the dolls were except for their color‚ to test children’s racial perceptions. Their subjects‚ where at least the children between the ages of three to seven‚ were asked to identify both the race of the dolls and which color doll they prefer. Eye Color Experiment talks about on how children treated each other by eye color

Then‚ work with a partner to answer the following questions. 1. What are the variables in this experiment? Identify the manipulated and responding variables and two controlled variables. The manipulated variable is light intensity. The responding variable is pH. Controlled variables include the initial pH‚ the size of the plant sprigs‚ and time
