2 Angles make a difference Aim The aim of this experiment is to test whether the angle of sunlight affects the surface temperature on earth. Hypothesis I believe Block B will receive more sunlight than Block A‚ because the lamp shines directly onto Block B. Materials * * Lamp * 2 thermometers * 2 blocks of wood * Black plastic tape Procedure 1. Cut out two small identically sized pieces of black tape and attach onto wooden blocks so that they make pockets. 2.

The aim of our investigation is to find out whether the use of different sugar isomers with yeast‚ will affect the rate at which the yeast respires at. The sugars to be tested are fructose‚ galactose‚ glucose‚ lactose and sucrose. Their effects on the respiration rate of yeast to be observed through the measurement (cm3) of the displaced water‚ which will tell us how much CO2 has been respired over 2 minutes. To compare the effects an average will be calculated for each and a result will be drawn

In this experiment‚ the class examined how the rate of photosynthesis was affected by different light colors at different distances in shoots of a Cabomba plant. The plants were placed in two different beakers‚ one with recently boiled and cooled distilled water and the other with saturated sodium bicarbonate solution. The three different color photoflood lamps used for this experiment were white‚ red‚ and green at four distances of thirty‚ sixty‚ ninety‚ and one hundred-twenty centimeters away

My results and the graph indicate that as you add the caffeine to the daphnia‚ the eart rate of the daphnia increases for example the daphnia’s heartbeat is 120 without caffeine‚ however when caffeine is added it is increased to 168. My graph shows a positive correlation and the error bars are also very small which shows that the results have a small range which suggests that my results are accurate and reliable. I think that the experiment was conducted well however there may be some ethical issues

Analysis Is a magnet affect by warm or cold temperatures? This experiment showed that if a magnet is cold‚ then it will have more magnetic pull than a warm magnet. The independent variable is the temperature of magnets. The dependent variable is the magnetic pull of magnets. The experimental group is magnets exposed to different temperatures. The control group is the room temperature magnet. The control variables are the amount of time the magnets are exposed to different temperatures‚ the type of magnet

analysing the graph‚ you can see that there is a relation between the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size

2011 Affect of Sugars on Yeast Respiration Introduction Cellular respiration can be defined as the release of energy‚ or the breakdown of carbohydrates into carbon dioxide and water1. Cell respiration takes place in the mitochondria of animals and in the cytoplasm of plants. The formula for aerobic cellular respiration is: c6H12O6+ 6O2→6CO2+6H2O Aerobic respiration occurs when oxygen is present‚ while anaerobic respiration occurs when there is no oxygen present. In anaerobic respiration‚ ethanol

Data Analysis Does temperature affect the strength of Gorilla Glue? If two pieces of wood are glued together at a 90° angle and one is put in the freezer‚one at room temperature‚ and one heated‚ then the glued wood from the freezer will be stronger. The independent variable was the temperature. The dependent variable was the strength of the glue. Some constant variables were the amount of glue‚ the type of glue‚ and the type of wood used. The experimental group was the temperatures. The control group

Does Temperature of Kernels Affect Popcorn Yield? Project Design Plan This experiment will attempt to determine if the temperature that popcorn kernels are stored at will affect the amount of un-popped kernels when using a hot air popcorn popper. Popcorn kernels contain moisture inside of them which‚ when heated‚ turns to steam and expands that in turn causes the kernel to explode. Popcorn.org states that loss of moisture content can cause less yield amounts when popping popcorn (popcorn.org‚ 2014)
