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

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

AN ANALYSIS OF THE INTEGRATED MALARIA VECTOR CONTROL POLICY IN GHANA INTRODUCTION Malaria is a major public health problem in Ghana. It is a leading cause of morbidity and mortality‚ especially in children under five years of age and pregnant women. It is the most common cause of outpatient visits‚ hospitalization and death. Malaria is also a development problem as it has a serious socio-economic impact on families and the nation‚ through loss of work‚ school absenteeism and high levels

and force) Aim: To show the relationship between Mass‚ the force acting on it‚ and acceleration by gathering data through investigations. Hypothesis: As Mass increases‚ Acceleration Decreases. Therefore‚ Acceleration is inversely proportional to mass. Introduction A force is a push or pull acting upon an object‚ as a result of its interaction with another object. In a state of motion‚ an object experiences different forces which influences its movement. There are many different types of forces which

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
