Analysis Of Balloon Lab Report

2. Obtained a 2-3 cm strip of magnesium metal ribbon and coiled it loosely into a small ball. Added the magnesium metal to the acid in the test tube.

Audience Relevancy: Learning how to make balloon animals is cheap, entertaining, and can be shared with other people.

* According to by surroundings the fur does not make the balloon to be attracted to anything. With my hair only a bit does is make it rise but not really. It can be because the rabbits fur is thick compared to other charging objects.

The initial circumference of the balloons were 41.5cm. The temperature of the hot water was 58℃, the room temperature water was 25℃ and the cold water was -4℃. After the balloons were placed in the water for 3 minutes, we got our results. The final circumference of the balloon in the hot water was 40.5. It shrank 1cm less which is a surprise since it should expand.

The mass of Mg must be measured at every stage to determine the ratio. The volume of HCl added to Mg, needs to be noted down too.

A strategy that can be implemented is for example if a wet beaker were fall and break it’s best not to touch the broken shards and to call for the teacher’s assistance. I believe that I was able handle any kind of safety concerns in this practical fairly well. To ensure that no breakage occurred I carefully handled the beakers and test tubes by drying immediately after washing and placing them as far as possible from the edge of the

Again measure the distances to each of the dots, and record the distances under "Time 2" on the worksheet. 5. Inflate the balloon in 2-inch (5-cm) increments three more times. After each inflation, measure and record the distances on the worksheet. 6.

The Cycle of Cellular Respiration and Fermentation Introduction: In this Cellular Respiration and Fermentation lab, we discuss about the cellular respiration which is classified as an aerobic process and fermentation which is anaerobic process. An aerobic process is where it contains oxygen unlike the anaerobic process does not. In the aerobic process there are 4 steps that should be recognized: glycolysis, conversion, citric acid cycle, and the electron transport chain. This experiment contains or uses the yeast concentration to see how much CO2 developed over 20 minutes, counting per 2 minutes and measuring how much has progressed.

D. When the balloon is secure you squeeze all the water beads into the balloon.

One at a time, repeat steps 4, 5, and 6 with test tubes #2, #3, and #4.

1. Gather the test tube holder, small stopcock, 10-mL syringe (titrator), and 2 thick textbooks and the LabPaq box or 5-6 thick textbooks.

Put the test tube where it will stand upright securely, or have a partner hold it. Fill it halfway with vinegar.

Inflate the balloon (by blowing through the straw, if you attached it to a straw).

Purpose of Investigation To study how pH and temperature would effect the reaction rate for amylase on starch. Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under various conditions.

The first step of the experiment is to make sure the crucible and cover are clean by washing them off with water. To dry the equipment place on the clay triangle and leave in the hottest part of the flame for 3 mins. Once time is up, allow the crucible to cool. Once cooled, measure the mass of the crucible with the scale. The next step would be to break the 10cm magnesium ribbon into small pieces, and place these pieces in the crucible. Find the mass of the crucible and the contents. Place the cover on the crucible and lay on the clay triangle. Heat the crucible and contents gently for 2 minutes. After this time is up, tilt the cover to provide and air opening. Tilt the cover using the crucible tongs. Now, heat the crucible and contents strongly
