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

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)

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

Ivan Chavez B1 Invasive Species: The Mexican Fruit fly An invasive species is a species that does not naturally take place in a particular area and with its arrival brings economic‚ environmental or human harm (1). Recently there has been a bigger emphasis on invasive species (1). They are threatening our agriculture and forests and causing major impacts to our cities (1). The characteristics that make the species thrive in their environment vary with each. Their characteristics

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

One day I noticed that the bananas in my kitchen were always turning brown quickly. I wondered which fruit decomposes the fastest. Id ecided to compare a banana‚ pear‚ apple‚ strawberry‚ and orange. I gathered my materials: 1 of each fruit‚ 5 see-through disposable plastic containers‚ and my camera (so I could take pictures of the fruits). My hypothesis was that the strawberry would rot first‚ followed by the banana‚ then the pear‚ and then the apple. I didn’t think the orange would even rot at all
