- There are no major changes in the colour of the eggs but we are expecting to see a slight change in the colour of the eggs by this Friday.

What did we do?

- First, we labeled each egg ( another batch of eggs ) ( top egg 2 bottom egg 1 ) ( The pH value on each egg )
- Then, 2 weighed the eggs for test 2 and recorded down the results on the logbook while the other two placed the 1st batch of egg (test 1) into their respective pH solutions ( 2 per bottle )

Day 2 of preparation for experiment (25/7/13)

Lesson 15: 

What did we do?

- We used the weighing balance to find out the weight of each egg. ( This is only for test 1 )
- We grouped the eggs together in a beaker and labeled each beaker with a different pH (pH 3, 4, 5, 6, control)
- Then, we labeled the top egg in each beaker number 2 and the egg at the bottom we labeled number 1.
