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

WHAT IS PHOTOSYNTHESIS? 3 Every day the total amount of energy that is captured through photosynthesis all across our planet is equal to approximately 135 terawatts. Now to put this number into perspective the entire human race consumes approximately 15 terawatts of energy daily. This means that there is 9 times more energy being absorbed every day through photosynthesis‚ as there is energy being consumed by all of mankind (Bridges 2008). In order to fully understand photosynthesis

The data found in this experiment supported the initial statement in the hypothesis‚ that blue would have the highest rate of photosynthesis (see Figure 7). The second part of the prediction was refuted by the data‚ as green had a higher rate than both yellow and red. This result seems to go against the experiment‚ however the answer is in Figure 5. When adding green food coloring to the solution (see Methods) dilution also took place. When comparing the wavelength of 540 nm (see Tables 1 & 2) with

Photosynthesis is a chemical process that converts the sunlight into a chemical energy that plants store for later. Without photosynthesis‚ the world as we know it would not exist. All the plants would die and so would a major food and oxygen source. During Photosynthesis water is sucked up through the roots up the stem and to the leaves. The leaves take in carbon dioxide and begin to absorb sunlight. these things combine to make glucose and oxygen. The plant then uses the glucose and oxygen is

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

processes of aerobic respiration and photosynthesis. To start‚ aerobic respiration can be defined as a biochemical pathway through which chemical bond energy is released from food and changed into ATP. On the other hand‚ photosynthesis is manufacturing of carbohydrates out of CO2 and the splitting of water in the presence of light. Photosynthesis and aer. respiration can be the same in many ways. For instance‚ both of them contain cycles. In photosynthesis‚ there is the Calvin cycle‚ and photosystem
