bubbles. So that’s why we call it a lava lamp inside of bottle. The conclusion is that you can make lava lamp household items if you use Alka-Seltzer‚ water‚ food coloring‚ and vegetable oil. So if you want to try just do what we did. That is our experiment. Why this happened because the Alka-seltzer had a chemical reaction beacuse of some powder on the outside of the alka-seltzer so the bubbles carried the food coloring up to the top of the bottle

The objective of the experiments is to see if mold will grow on bread if it has water. Molds are found everywhere. They are a type of microscopic fungi that lives on organic matter. They can be found both indoors and outdoors. No one knows how many species of fungi exist but estimates at least three hundred thousand or more. they have been on this earth for millions of years and believe to grow where there is moisture. According to the U.S.D.A eating bread with mold can cause allergic reaction and

The purpose of this paper is to elaborate on the Tuskegee Experiment based upon previous international study‚ it will also state the original study and where did it originate‚ the purpose of the study and the results. It will also state who or what were the principal investigators‚ the participants (gender‚ race‚ age)‚ why and how did this study end. The original study of the Tuskegee research was a disreputable medical experiment carried out in the United States between 1932 and 1972‚ in

Margaret Thatcher‚ otherwise known as The Iron Lady‚ was known for her role in saving Britain. The economy of Britain was facing tremendous troubles in the nineteen hundreds (Blundell 92). If the economy of Britain continued down the road it was going‚ Britain would have faced many great economic hardships that Margaret Thatcher prevented during her time in office. Margaret Thatcher‚ the first female prime minister in British history‚ exceptionally reformed Britain in a time of need while leaving

The Tuskegee Experiment In 1932‚ in the area surrounding Tuskegee‚ Macon County‚ Alabama‚ the United States Public Health Service (PHS) and the Rosenwald Foundation began a survey and small treatment program for African-Americans with syphilis. Within a few months‚ the deepening depression‚ the lack of funds from the foundation‚ and the large number of untreated cases provied the government’s reseachers with what seemed to be an unprecedented opportunity to study a seemingly almost

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

Salinity Experiment Aim To determine a method of measuring a soil sample’s salinity level in order to measure 3 samples’ salinity level. Hypothesis I think that by running a current through a salt solution and measuring the resultant amperage‚ a pattern in the recordings will help find a soil sample’s salinity level. Variables Controlled Amount of solution (100 mL)‚ supplied voltage (4V)‚ amount of soil (50 gm) & water (150 mL) in soil sample’s solution. Independent Amps recorded
