KCC Science Laboratory

The STEM 12 researchers of Kabankalan Catholic College, Inc. officially started the air-drying process for plant samples as part of their research methodology…

Air drying plays a vital role in preserving the plant materials for further testing and analysis. By drying their samples in a controlled environment, the researchers will ensure that their natural properties are retained, allowing them to achieve the most accurate results for our study. This step is essential to prevent decomposition and maintain the integrity of the plants.

As they continue with this process, they will carefully monitor and adjust the conditions to guarantee its success. Stay tuned for more updates as they advance in their research journey!

🧪 Exploring Chemistry at Home: Testing Acidity and Basicity with Grade 7- St. Theresa! 🏠

Our brilliant students from Grade 7 St Theresa took their chemistry knowledge into the real world by testing the acidity and basicity of common household compounds! This fun and interactive activity helped them understand the pH scale and how it relates to everyday products.

🔍 What they did:
Using pH indicators like litmus paper and natural pH testers (e.g., red cabbage juice), the students tested items such as:
• 🍋 Lemon juice (acidic)
• 🧼 Soap (basic)
• 🥤 Soft drinks (acidic)
• 💧 Baking soda solution (basic)
• And more!

📖 What they learned:
• How to identify acids and bases based on their pH value.
• The chemical properties that make substances acidic, basic, or neutral.
• The practical uses of acidic and basic compounds in daily life.
• The importance of pH balance in health, household cleaning, and the environment.

💡 Why it matters:
Understanding the chemistry of household products empowers students to make informed decisions in their daily lives. From knowing why vinegar works as a cleaner to how antacids neutralize stomach acid, the applications of this knowledge are endless!

👏 Amazing work, Grade 7-St. Theresa, Your curiosity and hands-on exploration bring chemistry to life. Keep experimenting and uncovering the science behind the world around you!

🌱 Investigating Plant Cells: A Hands-On Experiment by STEM 11 - Sincerity 🌱

Today, our STEM 11 - Sincerity students embarked on an exciting journey into the microscopic world of plant cells! Using onion epidermis as their specimen and iodine solution as a staining agent, they explored the intricate structures that make up the foundation of plant life.

🔬 What they did:
The students carefully peeled a thin layer of onion skin, placed it on a glass slide, and added a drop of iodine solution. This staining process highlighted key cell components, such as the nucleus, cell wall, and cytoplasm, making them clearly visible under the microscope.

📖 What they learned:
Through this activity, the students:
• Observed the rigid cell walls unique to plant cells.
• Identified the rectangular shape and organized arrangement of cells.
• Discovered the importance of iodine in enhancing visibility by staining the nucleus and other structures.
• Gained practical skills in slide preparation, microscope handling, and scientific observation.

💡 Why it matters:
This hands-on investigation not only deepens their understanding of plant cell anatomy but also nurtures their curiosity, critical thinking, and appreciation for the scientific method.

👏 Great job, STEM 11 - Sincerity! Your enthusiasm and dedication to learning continue to inspire. Keep exploring, questioning, and discovering!

📸🔬 A Look Back at Last School Year’s Science Lab Adventures! 🔬📸

Last school year, our Kabankalan Catholic College, Inc., Science Laboratory was buzzing with energy and discovery! Students engaged in hands-on experiments, bringing science to life through practical applications in biology, chemistry, and physics. 🧬🧪

From dissecting specimens to mixing chemicals and observing fascinating reactions, our students explored complex concepts in an interactive and safe environment. Each activity sharpened their analytical skills and sparked a deeper passion for the wonders of the natural world. 🌍✨

We’re proud of the growth and curiosity our students showed last year, and we can’t wait to see what the future holds for science at KCC! Stay tuned for more lab moments. 👩‍🔬👨‍🔬

Examination of Scale specimens which found out positive for Malassezia furfur, a fungal specie… Each specimens were placed on a clean microscope slides and a drop of 10% KOH Solution was added directly to each scale specimen using dropper. The KOH solution aided in dissolving the keratinized material present in the scale. Visualization of hyphae (spores) were found which revealed the typical appearance of Malassezia species, including pseudonycelia and mycelia in a yeast like form, indicating that the KOH test was positive.

Positive result is an indication that the specimens are subjected for culturing of Malassezia furfur using Sabouraud dextrose Agar.

Brain dissection activity in Science 10 typically involve students examining the external and internal structures of a preserved brain specimen. This hands-on activity allows students to learn about the anatomy and function of the brain firsthand.

Students were introduced to the major structures of the brain, including the cerebrum, cerebellum, brainstem, and various lobes and regions. Under the guidance of the teacher, students carefully dissect the brain to explore its internal structures. This may involve making incisions to reveal the corpus callosum, thalamus, hypothalamus, hippocampus, and other internal structures.

Brain dissection activities provide a valuable opportunity for students to deepen their understanding of neuroscience concepts and gain practical experience in anatomical exploration. They also foster skills in observation, critical thinking, and scientific inquiry.

The Grade 9 St. Ignatius students have conducted flame test activity which involves burning different chemicals (Chlorides) to observe the characteristic colors of their flames. Each element emits a unique color when heated, due to the excitation and relaxation of electrons in the atoms. By observing these colors, you can identify the presence of specific elements in a compound. It's often used in chemistry education to teach about atomic structure and spectroscopy.
