Crater Design Experiment Aim: To see how the height in which the ball is dropped from affects the depth of the crater. Hypothesis: I predict that as the height in which the ball is dropped from increases‚ so does the depth of the crater (the data will be directly proportional). The scientific knowledge which supports this is that the golf ball has a gravitational potential energy which increases as the ball is dropped from higher heights. When the height increases the ball gains more gravitational

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);

Sulfa Drugs: Preparation of Sulfanilamide Introduction The purpose of this experiment is to prepare sulfanilamide from p-Acetamidobenzenesulfonyl chloride. This will be done using reflux‚ vacuum filtration‚ and melting point determination. Experiment Scheme6 Figure 1. Reaction equation.6 A hot water bath was prepared in a fume hood using a 250-mL beaker. 2.5 g of p-acetamidobenzenesulfonyl chloride was placed into a 50 mL Erlenmeyer flask and 11 mL of dilute ammonium hydroxide solution

Change in Precipitation Ramon Pena BIO101 February 14‚ 2011 Dr. Richard Steiner Change in Precipitation Introduction This experiment will take course during a 300-year-time -period simulation. This experiment will consist of two islands‚ Darwin Island‚ Wallace Island and take only into account the bird population of these two islands. The parameter will stay the same‚ except for one variable; precipitation. I will record how the precipitation changes the beak size of the bird population

EXPERIMENT 5 TRANSVERSE STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY

AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature
