Class Experience
Have you ever tried to teach kids about the fundamentals of acids and bases, only to be met with
groans and other boring reactions?
We understand there is no fun. Perhaps you're enthused
about the concept and want to make it engaging for the kids, but you're having trouble coming
up with a means to bring such a seemingly monotonous subject to life.
Who does not enjoy experimenting with chemistry at home?
Allow your child's curiosity to
spark by a series of hands-on STEM explorations. In this one-day course, students will
explore acids and bases. They will learn the following,
What are the indicators, and how can we prepare natural Indicators at home.?
What is the purpose of using these acids, bases, and indicators?
How to make observations, form a hypothesis, conduct an experiment, ask questions, draw
conclusions, and report results.
The followings are the topics and experiments in this course. The items necessary for each
activity will be listed in the Learner Supply list.
Schedule
• Introduction of acid and base
• Differences between acid and base
• What is Neutralization
• Experiment 01: Check the taste of acid and bases (Ex: lemon juice, orange juice,
vinegar, curd, sugar, and grapes) (sour/bitter or any other)
• What is a PH scale?
• Experiment 02: Preparation of Red cabbage pH indicator and observation of color
changes
• Introduction of Natural and synthetic indicators
• Experiment 03: Preparation of Litmus paper and observation of color changes
We will take basic safety precautions. These items are not dangerous but can irritate the eyes
or sensitive skin. Be sure to wear your lab coat and keep your hands away from your face
or wear safety glasses and gloves as necessary.
Please ensure that you have gathered all the materials required for preferred
experiments before the session.

Hello, I am Dilshani Ranasinghe. I have a passion for teaching and research. I am very happy
to teach your learner. I am currently working as a Laboratory Technical Service Officer
(Technical Officer) in the Government Analyst's Department since 2014. I believe that
learning should be fun, and relatable, and encourage further curiosity, and this is how I approach
each of my classes.
My goal is to ensure your child feels comfortable, is respected, builds their confidence, sees
their potential as they master content in a positive learning environment, and promotes
intellectual diversity. I firmly believe your learner will leave my classroom with the tools they
needed to succeed.
My educational philosophy is that it is just as important to increase a student's interest in
science as it is to learn the material in a class. I look forward to seeing you in class!
