Red Cabbage Indicator Aim – To create a pH indicator out of a red cabbage solution and to construct a basic pH scale to determine the pH of unknown solutions. Materials - • red cabbage leaves • 250 mL beaker • hotplate or Bunsen burner‚ tripod‚ gauze mat and bench mat • 10 test-tubes – equal size • test-tube rack Methods - Part A: Making the indicator 1. Tear up one or two red cabbage leaves‚ and place them in the beaker with enough water so that the cabbage is just covered. 2. Heat the beaker

Measuring Cup Water Timer Tongs Observation/Question: Do all paper towels have the same absorbency? Are more expensive paper towels more absorbent? Hypothesis: I think more expensive paper towels are more absorbent than less expensive paper towels. Experiment: Controls: Same amount of water for each paper towel; same size paper towel used; the same surface used in each attempt; process to determine the amount of water left; the water will be left on the paper towel for the same amount of time; test

Knowing that calcium helps keep humans healthy and have stronger bones‚ I wanted to experiment how calcium might aid in the growth of lima beans. Background Information: In plant growth‚ calcium effects the metabolic process of other nutrient uptake that is vital for growth of the plant. Calcium also strengthens the cell wall structure (It is an essential part of the cell wall);

Method: The placebo controlled experiment design can be helpful in this study. In order to determine the effect of caffeinated energy drink‚ the total of twenty athletes will volunteer to participate in it. All the participants will be divided into two groups; ten will drink caffeinated energy drink and other ten will ingest placebo (no caffeine content). The drinks will be served in an opaque bottle to avoid its identification and to make sure that player drink beverages in it entirely. Both the

in the Mentos and Diet Coke. The structure of the Mentos allow carbon dioxide bubbles to form extremely rapidly. When this happens‚ you get the physical reaction of the coke exploding out of the bottle. Other carbonated drinks also work with this experiment. (Hiskey) One thing that contribute to this explosion is the structure of the Mentos. Mentos are fairly dense and sink rapidly‚ quickly creating bubbles that seed further

In our society‚ there are many social norms we are expected to abide by. These unwritten rules and standards of behavior often go unnoticed‚ leaving society to take them for granted. We only become truly aware of the norms of society when they are actually violated. When a violation occurs‚ those who continue to conform may respond with positive or negative sanctions‚ such as humor‚ alarm‚ irritation‚ fear‚ or a wide variety of emotions. Our society also relies on language as its major bases for
