How to Pass in Chemistry? Use these Tips

Share these Tips with you Students and you will real big

Chemistry is a Science subject and as we all know, sciences are majorly pegged to the practical skills since every mark in practical is equivalent to 1%. As much as practical is very important, we should not sideline the theory part as it also comprises of 60% at the end of the two papers.

From experience as a chemistry teacher, I know that quite a number of students fear science subjects and more especially Chemistry. But today I want to give you the tips if you are a student in high school or a high school teacher that will improve your performance or the performance of your students respectively.

Let’s now take a look at the mechanisms that we can employ so that chemistry performance can be improved.

a) Form One work

The basis of chemistry depends of the foundation set in form one. This foundation is very important and is meant to trigger the mind of the learner to understand the importance and the reason to study chemistry as a subject. But basically, the most important part of chemistry in the form one class is Acids, bases and indicators. In this topic we tend to study the properties of acids and bases. We also study the behaviour of acids and bases when added to indicators. We also study the various reactions involving acids and bases, acids and metals, acids and carbonates or hydrogen carbonates. In this case the teacher should emphasize on the products that are expected once these reactions take place. The teacher should also emphasize on writing word equations involving the above reactants. By doing this, the student will get to understand how those reactions are written and the expected products. This sets the basis for writing chemical equations when it comes to form two now when we don’t use words but chemical formulae.

Other topics like Classification of substances, air and combustion and water & hydrogen are equally important, but the most important is Acids Bases and indicators and to be precise the part that is quite important is writing of word equations.

b) Form Two Work

It’s important to note that form two has got to most crucial topics that learners and teachers should put a lot of emphasis on, and these includes, Structure of the Atom and the periodic table and Chemical Families. In these topics we are made to learn about what an atom is, the structure of that atom, the particles that are contained in that atom and the characteristics of these particles. From these particles we are able to learn about other things like the atomic number, number of protons, Neutrons and mass number of an element. We also learn about the representation of an atom by the use of the( ×) and Dot (•) diagrams. We also learn about the energy levels and distribution of electrons in each energy level. The most crucial part too is about Ion formation. Here we get to understand that elements can lose or gain electrons to form an ion. Always teachers should emphasize that metals they form an ion by losing an electron(s) while non-metals forms ions by gaining electrons for them to be stable. The teacher now after this, should emphasize on mastering of the first twenty elements, their symbols, writing of chemical formulae of compounds by the use of valencies of elements which must emphasized and the lastly will be on writing chemical equations, balancing them and inserting correct state symbols. Once all this is done other things like Radicals and isotopes are also very important since the learners must understand them fully before moving to the next topic. Once the learners have mastered about the groups and periods in this topic, now the teacher can move comfortably to the next topic and that is Chemical Families. In this topic the teacher should emphasize of the types of chemical families that we have, the trends in those families and properties of those elements in the same group both physical and chemical properties. The teacher should also emphasize of the properties across the period and give concrete reasons for the properties observed. The teacher should not move to the next sub topic if the learners have not mastered these concepts. Once this one has been handled properly, then the learners are set to hand other tasks that lie ahead of them with a lot of ease. These three topics both in form one and form two are very key and determine to performance of a student. If the student has understood all these concepts correctly, then the student can be able to handle other tasks ahead of him/her without straining.

The fact from experience is that, whenever a student has masters all above, tackling chemistry theory in other classes becomes super simple and enjoyable.

c) Chemistry Practicals.

Practical is the back borne of chemistry. Therefore it means that once a student has mastered the theory part, the other part is practicals. Chemistry Practicals range from Volumetric Analysis, quantitative analysis which involves Energy changes and Rates of Reactions, Solubility and then lastly qualitative analysis.

In this part, the teacher should take his time to take the students through all these practicals step by step and he should ensure that each practical has been mastered by the learners before moving to the next practical. In this case the teacher should have a demonstration with the students and then give the students room to carry out the same practical on their own in order to improve their practical and psychomotor skills. In such a scenario, the teacher should give room to each student to carry out the practical on his/her own with the teacher going round to check each and every student work. Through this, the students will get used to these practicals and they will be very good to handle any practical set in any exam.

After all the practicals have been done and the syllabus is over, the chemistry department should produce copies of practical manuals that can help the learners conduct a practical without the help of the teacher. This will allow the learners improve their practical skills.

d) During Examinations, Encourage learners to read instructions and go through all the questions in the whole paper.

Sometime many students once they have been give a question paper they tend to begin immediately without reading the instructions given in that paper. Some they tend to panic when they see their neighbors have started answering the questions and they also want to rush and be at the same level like his/her neighbor.

Always encourage learners to take the first five minutes to go through the instructions as in some cases, under instructions is where some Constants are given that are required to be used in the calculations.

Also encourage learners to go through all the questions before they start answering. By doing so, the student gets to register the questions in the brain and as he/she answers other questions, he/she will be thinking of an answer to the already read and registered question.

Also encourage the students to begin with simple question first and leave alone the harder ones so that they will come back to them later after completing the simpler ones. This will help the student not to leave a simple question unanswered when time allocated for the exam is over. Remember that if a students takes a lot of time thinking of harder questions, he/she will waste a lot of time which he would have used to tackle simple questions. It’s advisable to start with simple questions then come to harder ones when the mind is now fresh and has thought about that question over and over again. You will get to remember a few concepts in that hard question which will make remember other things that you had forgotten.

Always encourage students not to leave blank spaces in examinations,let them write even a formula or anything that is in chemistry as it may earn him/her even a mark.

Therefore my fellow teachers and students who are reading this article, please make sure you follow these guidelines and I believe that you won’t regret your performance.

Thanks for reading and welcome again here for more encouraging and inspiring contents.
