Designing a Digital Science Textbook: Making Chemical Reactions Visible and Meaningful

This digital textbook presents the topic Chemistry of Changes, focusing on physical changes, chemical changes, and different types of chemical reactions such as thermochemical, photochemical, and electrochemical reactions. Through activity-based explanations and clear illustrations, the digital format helps students understand how substances change and how energy is involved in these changes.

🖥️E-Content Development on Characteristics of Electric Charges

E-content plays an important role in modern education by integrating technology with teaching and learning. It makes the learning process more engaging, interactive, and effective by using digital resources such as text, images, audio, and video. In science education, e-content helps students understand abstract concepts clearly through visual explanations and narration. It also supports self-learning by allowing learners to access lessons anytime and anywhere, making learning more flexible and student-centered.

The e-content developed is for Class VIII Science on the topic “Characteristics of Electric Charges.” The lesson explains electric charge, structure of the atom, charging by gain or loss of electrons, and the characteristics of electric charges such as attraction and repulsion. PowerPoint was used to prepare the presentation slides, AZ Screen Recorder was used to record the lesson, and InShot was used for video editing. Simple language, relevant images, and audio narration were used to make the content clear and learner-friendly.

😍Week 5 of Second Phase Teaching Practice at St. Margaret’s Girls High School, Kundara

 🌼 Day 19 – Strengthening Concepts Through Remedial Teaching

The nineteenth day began as we reached the school at 9:00 AM and signed the register. The morning assembly at 9:20 AM included the prayer, pledge, thought, news reading, and national anthem. During the 1st period, I taught Chemistry in 9B, handling the topic Surface Area of Reactants and Temperature from the unit Chemical Kinetics. Students engaged well with the examples provided. At 12:15 PM, we completed our regular noon meal serving duty. During the 5th period, I conducted a remedial class in 9B based on the diagnostic test findings. This session helped reinforce concepts where students needed additional support. The remaining periods had no assigned classes, allowing time for teaching aid preparation and updating records. The day concluded at 3:45 PM with the national anthem.

                                       

🌺 Day 20 – A Smooth Physics Session on Lightning Safety

The twentieth day began with the morning assembly at 9:20 AM. The morning session had no allotted classes, giving time for organizing teaching materials and preparing upcoming lessons. At 12:15 PM, we performed the noon meal duty. During the 5th period, I handled a Physics class in 8C on Lightning Conductor and Lightning Arrester from Static Electricity. The students showed active interest in learning how these devices protect buildings. No further classes were assigned in the afternoon. The school day ended at 3:45 PM with the national anthem.

🌿 Day 21 – Introducing Magnets to an Enthusiastic Class

The twenty-first day started with the morning assembly at 9:20 AM. During the 1st period, I had a substitution class in 8C, where I taught Natural Magnets and Artificial Magnets from the unit Magnetism and Electricity. The students were enthusiastic and curious about the topic. At 12:15 PM, we carried out the noon meal serving duty. The afternoon session had no further classes, allowing time for preparing teaching aids and planning upcoming lessons. The day concluded at 3:45 PM with the national anthem.

🌻 Day 22 – Exploring the General Properties of Magnets

The twenty-second day began with the morning assembly at 9:20 AM. There were no classes in the morning, giving ample time to prepare materials and organize lesson plans. At 12:15 PM, we completed the noon meal serving duty. During the 5th period, I took a substitution class in 8C and taught General Properties of a Magnet from Magnetism and Electricity. Students participated well, and the class progressed smoothly. The day ended at 3:45 PM with the national anthem.

🎉 Day 23 – Revising Static  Electricity & Preparing for Exams

The twenty-third day began with the morning assembly at 9:20 AM. During the 1st period, I handled a Chemistry class in 9B on Catalyst and Its Nature from Chemical Kinetics. Students responded with interest and understood the key points clearly. At 12:15 PM, we performed the noon meal serving duty. In the 7th period, I took a class in 8C where I revised previously taught lessons and discussed important questions to support students’ preparation for the upcoming Christmas examination. The day concluded at 3:45 PM with the national anthem.
