elements constructed within the context of good vs‚ bad. Blah blah blah blah After this‚ you need to state the problem (ideally in 100 words) not necessarily in question form‚ and the 3-4 main objectives or 3-4 guide questions (remember that the objectives are just the statement of the guide question‚ written declaratively.) The themes embedded within Disney films blur the boundaries between reality and fantasy. Because of its popularity‚ it has a tendency to “corrupt” children’s perception

What reaction(s) could be occurring as the Na and K surface tarnishes? Write balanced equations for each reaction you can imagine. Hint: Recall air is mae up of water vapour‚ nitrogen‚ and oxygen. Suggest why oxygen (found as O2 in the air we breathe) is more likely to react rather than nitrogen (N2). The surface of Na and K could be tarnished because of reaction with oxygen. If Na or K is burned in air‚ the results are mainly formation of white sodium peroxide

Control experiments - an experiment in which the variable factors are controlled so as to make it possible to observe the results of varying one factor at a time. Qualitative descriptive research (case studies) – Ultimate goal is to improve practice. This presupposes a cause/effect relationship between behavior and outcome; however‚ this method will ONLY let you hypothesize about variables and describe them. When you move to show correlation among them‚ you’re doing quantitative work. But remember
