An Experiment to Test the Effect of Temperature on the Rate of Photosynthesis in Green Algae Background Photosynthesis is an amazing process where plants are able to create their own food as well as oxygen using sunlight‚ carbon dioxide (co2)‚ and water. The part of the plant responsible for photosynthesis is the enzymes in the chlorophyll (structures that carry out photosynthesis located in leaves). Photosynthesis is the process of creating glucose. Water + Carbon Dioxide + Sunlight = Glucose

How Does the Thermometer Work? A thermometer is a device that measures the temperature of things. The name is made up of two smaller words: "Thermo" means heat and "meter" means to measure. You can use a thermometer to tell the temperature outside or inside your house‚ inside your oven‚ even the temperature of your body if you’re sick. One of the earliest inventors of a thermometer was probably Galileo. We know him more for his studies about the solar system and his "revolutionary" theory

the effects of adding heat and cold to the germinating peas‚ dormant peas‚ and glass beads to find how this changes their cellular respiration rate. The effects are measured by testing the amount of CO2 released from each sample with different temperatures applied. This is important to learn the difference between the rate of respiration during dormancy and germination. Hypothesis My hypothesis for this experiment is that the germinating peas that have heat applied will give off the most CO2 because

The objectives of the experiment are to determine the specific heat of metal specimens using the method of mixture‚ to measure the equipment properly‚ to carefully measure the temperature of the equipment‚ to be patient while waiting for the output of the experiment and to be precise in computing for the specific heat of the specimen. Theory Blanza‚ J.‚ Guevara‚ C.‚ Morsiquillo‚ A.‚ Nacu‚ G. (2012) noted that the transfer of energy is made by temperature difference between

electronic heat sensors to record body temperature‚ can be used in the rectum‚ mouth or armpit. The most accurate way to take a child’s temperature is to use a digital thermometer‚ either rectally or orally. Rectal temperatures provide the best readings for infants‚ especially those 3 months or younger as well as children up to age 3. If you use another type of thermometer to take a young child’s temperature and you’re in doubt about the results‚ take a rectal temperature. For older children and adults‚

Understand and observe the concept of Heat Transfer‚ by measuring the temperature distribution for steady state conduction of energy through a specific efficient unit. • Understand the Fourier Law of heat conduction and the usage of its equation in determining the rate of heat flow via solid materials. II. Theory : The Fourier Rate Equation: When a plane section of ∆x and a constant area A maintains a temperature difference ∆T‚ then the heat transfer rate per unit time by conduction

I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

variance in final temperature for each experiment was less than 10 percent providing proof of repeatability. Equipment used during the experiment included a gram scale‚ thermocouple‚ Styrofoam cup‚ glass beakers‚ microwave‚ an ice bath and ice. The first half of the experiment was dedicated to the mixing of two containers of water at different temperatures. The mass of the water in each container was measured and the containers were then heated or cooled to achieve the temperature desired for the experiment
