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

Risk Taking Experiment A. There are many risks in life one must take. I had several options to explore for this experiment such as going on a drop roller coaster‚ sky diving‚ and killing insects. I thought that sky diving would be fun‚ but I am not old enough to do because the minimum age requirement was eighteen years old. I also explored the idea of killing insects especially spiders which I hate the most‚ but I thought going on a drop roller coaster would be more interesting. B. I chose the

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

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);

essentially of a movable iron-core coil mounted on a pivot between the poles of a permanent magnet. When current flows through the coil‚ it creates a torque which causes the pointer to deflect. The amount of current through the coil determines the deflection of the pointer‚ which is registered on a scale attached to the meter movement. 2. What device is used to extend the range of the DC ammeter and how is it connected to the basic meter? The analog DC ammeter measures the current through a particular
