The effect of temperature on the cell membranes of beetroot cells and amount of pigment released. Apparatus • Corer size 4 • White tile • A Beetroot • Automatic Water Bath • Segregated knife • A thermometer • Stopwatch Method: • First take the white tile and the corer. Then collect a cylinder of beetroot by pushing the corer into the beetroot and withdrawing it. The cylinder remains inside the corer- so push it out with the end of a pencil. • Collect 3 cylinders

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)

of Food Date Submitted: April 1‚ 2012 Date Performed: April 1‚ 2012 Lab Section: Chem-180-DL1 Purpose: The purpose of this lab was to measure the energy content of three different food items using the change in water temperatures from the heat of the food. Another purpose was to take the information acquired and become familiar with energy units used in food such as calories and joules. Procedure: The first step in this experiment was to weigh and record an empty 100mL beaker. Then fill

HYPOTHESIS: I think that when you are stressed‚ the body temperature will be affected because the more you are stressed out‚ the higher your blood pressure gets and then your blood heats up and the temperature changes. MATERIALS: Basal thermometer Participants Very‚ Very challenging test Stopwatch PROCEDURE: 1. Make a very‚

The second goal was to measure the heat capacity of the constructed calorimeter. The third and fourth goal was to determine what reactions were to be investigated and what variations of the reactions would be studied. The two requirements that were kept in mind while creating the calorimeter were that it should be a good insulator‚ meaning that it does not allow for the transfer of heat between two systems in an environment‚ and that it should have the lowest heat capacity possible (ideally 0C) so

It was in 2nd century B.C that the first bath houses were built and back then they were simple washing facilities for men only. By the time of Augustus there were 170‚ privately owned bath houses. As they became more popular in the imperial age‚ they became public bath houses and people went there to bathe‚ meet‚ or discuss business. However‚ men and women did have different bath houses.• You had to pay to use the baths. • You could buy refreshments at the baths. • Only the very biggest baths had

minutes‚ using different materials to insulate the heat. The five materials that will be tested are: Aluminium foil‚ plastic wrap‚ newspaper‚ felt‚ and bubble wrap. Aluminium foil is a reflective material; this means that it bounces the thermal energy back to the foiled object. It also absorbs the heat. Not only does it stop heat loss‚ but Aluminium foil is also useful for protecting objects from gaining unwanted heat. Plastic wrap insulates the heat but makes it that it is too hot to touch. Plastic
