 * Title: Report on Egg-citing Egg-splore Science Practical**
 * Topic: Homeostasis**

To find out how the specially prepared shell-less quail eggs will react in terms of weight, length and volume to the two external conditions provided – water and syrup. Our group predicted that the quail egg in the control set-up will not have any visible changes whether it is in terms of weight, length or volume. The quail egg submerged in water however will expand in all three areas. The quail egg submerged in syrup on the other hand will decrease in weight, length and volume.
 * Aim of our Experiment**
 * Prediction**
 * Methodology**
 * 1) Weigh the first egg with the weighing machine and record the measurement in the notebook in terms of grams (g) to 2 decimal places.
 * 2) Measure the length of the first egg from the top axis to the bottom (the greatest length possible) using the vernier caliper and record the measurement in the notebook in terms of millimeters (mm) to 1 decimal place.
 * 3) To find the volume of the first egg, fill the measuring cylinder with 100cm 3 of water. Next, gently roll the first egg into the measuring cylinder. Following that would be to read the measurement. Subtract 100cm 3 from the volume of the water and egg and that would result in the volume of the first egg. Record the volume of the first egg in the notebook in terms of cubic centimeters (cm 3 ).
 * 4) Repeat Steps 1 to 3 for Egg 2 and 3 as well.
 * 5) Take Egg 1 as the control set-up and leave it in the Petri dish.
 * 6) Place Egg 2 in the beaker of water and place egg 3 in the beaker of syrup for 20 minutes.
 * 7) After 20 minutes, take egg 2 and 3 out of the beakers.
 * 8) Repeat Steps 1 to 3 for Egg 1, 2 and 3 and record the measurements in the notebook.
 * 9) Consolidate the before and after measurements for each egg into a table before calculating the percentage difference between each measurement before and after the 20 minutes.

**Difficulties Encountered** Generally, we had to be very careful with the quail eggs as they are very soft, especially without their shells. The most difficult part of the experiment was to measure the volume of the eggs as we had to gently roll the eggs into the measuring cylinder and at the same time make sure that minimal amount of water splashes out of the cylinder. This was to ensure that the measurement will not be rendered inaccurate. We had to make sure that the quail eggs are clean and are not “contaminated” by the other solutions like water or syrup. This is especially so for the control set-up. The spoon that we used to move the eggs around had to be thoroughly washed every time it comes into contact with a particular quail egg. Also, our group tries as much to repeat the measurement process at least thrice for the result to be more accurate. For example, weighing egg 1 thrice, making sure that the measurement result is of a close range. We assumed that the volumes of the liquids (water and syrup) provided for us will not affect the results of the measurement. Also, we assumed that the quail eggs are made up of the same components.
