Abstract: This experiment will determine if jumping beans are alive. We tested two groups. Group A and B. We put them in two different areas. Three beans were put in a lit area and three were put in a shaded area. It was found that if the depending on how lit the area is the more movement we saw from the jumping bean. Therefore it can be said that jumping beans are alive and respond to stimuli. Introduction: This Experiment “ Mexican Jumping Beans” focuses on how jumping beans respond to different

RESULTS Aphid survival experiment Aphid survival rate varied with both of different combinations of predators-aphids and various times in presence or absence of ants (Table 2). GLM results showed that the interaction of ‘time × different combinations of predators and aphids × ant’ (F = 0.211; df = 10‚ 317; P = 0.995)‚ ‘ant × time’ (F = 0.490; df = 2‚ 317; P = 0.613) and ‘different combinations of predators and aphids × time’ (F = 1.639; df = 10‚ 317; P = 0.095) on the survival rate were not significant

nitrate salts present in one flame test. The strontium flame admitted both a similar orange colour‚ but the strontium nitrate has a much more vibrant dark orange than the strontium chloride. Q2: Suggest reasons why the experiment tested both nitrate and chloride salts? The experiment tested both nitrate and chloride salts to allow us to compare which part of salt is responsible for the colour change of the flame. Q3: Suggest why flames on gas stove burn orange-yellow when a small amount of water

Galileo: Intellectual Revolution in the Renaissance Galileo Galilei (15641642) has forever played a key role in the history of science. He is a key figure in the scientific revolution of the 17th century. His work in physics or natural philosophy‚ astronomy‚ and the methodology of science still stir up a discussion after over 300 years. His responsibility in promoting the Copernican theory and his trials with the Roman Church are stories that are retold even today. This essay is an attempt to provide

A lab experiment is a method of research that enables the researcher to control the environment. It is a way of doing a research in a controlled environment on a certain behaviour which will have a cause and effect. It is done in a controlled environment so that extraneous variables are prevented from affecting the results. Behaviourists use lab experiments because they are interested in a cause and effect of certain behaviours. The aim is to control all relevant variables except for one key variable

Catalase Experiment Research Question: How does the weight of a piece of liver (0.4g‚ 0.8g‚ 1.2g and 1.6g in this case) affect the amount of gas created after 2 minutes when combined with hydrogen peroxide? Aim: To see find out how the amount of catalase correlates with the amount of gas created when in combination with hydrogen peroxide. Materials: 15g of liver 25 ml of hydrogen peroxide 1 scale 1 bucket 1 100ml graduated cylinder 1 250ml flask with bung 1 50cm tube (able to fix onto top of flask)

For this experiment‚ we started off by taking tubes numbered 1-4 and started adding one scoop of our enzyme catalyst‚ in this case‚ the yeast. We then proceeded to measure and add 1 mL of distilled water to test tubes A-D. To get a more accurate measure of 1 mL of distilled water‚ we used the dropper labeled “W” to drop distilled water into the 5 mL graduated cylinder until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and

Galileo‚ Through a Clear Lens Many people remember Galileo Galilei as simply the inventor of the telescope‚ and an important figure in science. However‚ Galileo’s life and pioneer thinking challenged the old world beliefs of the Church at a time when their word was law; and demonstrated his great courage‚ his strong convictions‚ and his thirst for knowledge. Galileo began his studies as a young boy at a monastery near Florence‚ Italy. In 1581‚ he gave up the monastic life at the request of his

The beginnings of these social changes are forever encapsulated in the works of this period. Galileo claims that the physical should solely be studied by means of the senses and reasoning. This opposed the natural order of the universe in his time. He was well aware that his concepts were new‚ in regards to his position in time. He knows that his
