Scientific Method Study of Plants ****** Biology 100 ***** ****** The Scientific Method is a series of steps used to basically form an opinion and test that opinion. The method steps include‚ observation‚ research‚ creating an educated guess‚ or hypothesis‚ testing that hypothesis‚ analyzing the test results‚ and recording the results as true or untrue. If testing of the hypothesis results in disproving it‚ the steps will begin again with a new hypothesis

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

to determine the solubility constant of calcium hydroxide. But‚ there are few limitations in solubility constant concept‚ like the Diverse Ion effect and the Common ion effect. Sources of error probably were the assumptions made throughout the experiment and can be explained further by the limitations of the solubility constant. ------------------------------------------------- ------------------------------------------------- Introduction In a reaction where a slightly soluble ionic solid

The Scientific Method This experiment was performed by using a systematic approach to identify six unknown substances. In the first half of the experiment six unknown substances were observed than measured by determining volume‚ mass and density. The second half of the experiment the unknown were placed in a test tube and tested for solubility. It was determined that the six tubes contained coffee‚ potting soil‚ brown sugar‚ baby powder‚ baking soda‚ and powdered sugar. By the use of the scientific

depression using the descriptive method. The researcher can start with case study; studying e an individual’s who has been diagnosed with a depression disorder. This way they could learn new things through this person’s actions. Moving on to the naturalistic observation to study a group of people with the same disorder. This study would be at natural as they could possibly make it. This would show them the different affect of depression on individuals. The correlation method can be used to study depression

Describe the physiological approach to the study of the mind. Explain how Donders experiment can be repeated in a modern laboratory using the physiological approach to the study of the mind Donder’s work attempts to describe the processes going on in the mind‚ by analyzing cognitive activity into separate stages. Until Donder’s work‚ many scientists had assumed that the mental operations involved in responding to a stimulus occurred instantaneously. Donder was particularly interested in "timing

a tremendous variety of oxidation states that appear in its compounds. The oxidation numbers range from Mn (III) in compounds like Mn(NO)3CO to Mn (VII) in KMnO4. Compounds of manganese range in oxidation number between theses two extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful starting material for the preparation of other Mn (III) compounds. Manganese (III) complexes are relatively stable and can be prepared

Stallings Period 2 January 26‚ 2013 Enzyme Catalysis Lab Report Background: Enzymes are catalyst‚ which affect the rate of a chemical reaction. One consequence includes the cell to carry out complex chemical activities at relatively low temperatures. In these reactions the substrate binds reversibly to the active site. The cause of this is a decrease in the energy needed to activate the reaction of the substrate molecule to from products. Every enzyme is particular for a reaction for the reason
