Practical Reflections

This is the section for my reflection on my practicals from term 1 and 2, we were learning biology in term 3 so there were no practicals for it.
Practical 2P01
For this practical, we aimed to find out the properties of acid bases and neutral solutions. Since this was our first practical of they year, it was a relatively simple one. We basically just did various things to test for the acidity of the various acids, bases and neutral solutions while writing down our observations. The problem however was that I was too brief in my explanation of my observation which resulted in quite a few red crosses on my practical.
Practical 2P02
In this practical, we investigated the action of dilute acids on metals. Eventually learnt that in this reaction, hydrogen gas is formed and we also learnt how to test for hydrogen using a burning splinter.
Practical 2P03
The aim of this practical is to investigate the dilute acids on carbonates.We found out that in this reaction, carbon dioxide is formed and how to test for it by bubbling it through lime water. We also first started balancing equations on this practical.

Practical 2P04
For this practical, we investigate the action of acid on an alkali. In this reaction, only salt and water is formed. I cannot say much about this practical as I was at a badminton competition as it was going on.
Practical 2P05
In this practical, we aim to find out the action of alkalis on ammonium salts. I was also gone for competition during this practical but my friends told me what basically happened and how they tested for ammonia gas and why its necessary to warm the mixture before testing with a damp, not dry, litmus paper.
Practical 2P06
In this practical, we tried to find out what a certain substance X is by conducting certain experiments and we eventually found out that it was ammonium carbonate. We also had to draw a flow chart to show how to identify certain unknown substances through scientific tests and experiments.
Practical 2P07
This is our first physics practical and our first practical of term 2. We explored how light rays are reflected from mirrors and to verify the Law of Reflection where the angle of incidence will be equivalent to the angle of reflection. For my practical, there was a bit of experimental error however our observations were all within the 2 degrees range so it was still fine.
Practical 2P09
In this practical we explore how light rays are refracted through the plastic block. I do not usually complain about practicals but really drawing all the rays of light, as it is refracted towards and away from the normal as it goes from air to plastic and plastic to air is really troublesome especially when we have to draw five different rays of light at different angles.
Practical 2P10
The aim of this practical is to measure the critical angle and investigate total internal reflection and to observe an optical fibre and understand how light travels through it. Today, we learnt about how if the angle of incidence from an optically denser medium to an optically less dense medium exceeds the critical angle, total internal reflection occurs and how to calculate the refractive index from the critical angle.
Practical 2P12
In this practical, we observe an image formed by a converging lens. By placing the object a nearer or further from the lens, the image captured differ greatly from magnified to diminished, from inverted to upright, from real to virtual.
Practical 2P13
For this practical, we will examine the carpel and stamen in different plant species and study the mode of pollination in different plant species.For this nature trail, we took multiple pictures of different flowers and finding the scientific name of each flower is really troublesome work as we can never really fully confirm whether it was really the same flower or not. However, it was really fun to move around and find different flowers even though it was raining.
Salt Preparation Practical
In this practical we prepared copper (II) sulfate from the reaction between a dilute acid and an insoluble base and the reaction between lead (II) sulfate from a precipitation reaction between dilute acid and an insoluble base. Not much to say about this one as I don;t really remember it too well.
