Materials Used: A mixture of sand and water Filter paper or a coffee filter Funnel Beaker or clear glass Stirring rod Clean container for filtered water Optional: Activated charcoal (to demonstrate advanced filtration) Procedure: Preparation of the Mixture: Students mixed sand and water in a beaker to create a dirty water solution. They stirred the mixture well to ensure the sand was fully suspended in the water. Setting Up the Filtration System: A funnel was placed on top of a clean beaker. A filter paper (or coffee filter) was folded and placed inside the funnel. Performing Filtration: The sand-water mixture was slowly poured into the funnel. Students observed how the filter paper trapped the sand particles while allowing clean water to pass through. Observation & Comparison: The filtered water was compared with the original dirty water. (Optional) A second filtration using activated charcoal was performed to show how additional filtration removes finer impurities. Observations: The initial mixture was cloudy due to suspended sand particles. After filtration, the water in the second beaker appeared clearer. The filter paper retained the sand, proving that filtration effectively separates insoluble solids from liquids. Learning Outcomes: Understanding the principle of filtration. Recognizing the importance of clean water and filtration in daily life. Developing observational and analytical skills. Conclusion: Through this experiment, students learned that filtration is a simple yet effective method for separating mixtures. They understood its real-world applications, such as in water treatment plants and household filters. The hands-on activity enhanced their comprehension of scientific concepts while fostering curiosity about environmental science.
Science Experiment- States of Matter (Solid, Liquid, and Gas)- Class 1st
Introduction Through interactive activities, young learners observed how ice (solid) melts into water (liquid), and how water can turn into gas (steam) when heated. They also explored the invisible nature of gases by feeling air from a fan and playing with inflated balloons. This engaging experiment helped children understand key scientific concepts in a fun and memorable way. By touching, seeing, and discussing real-world examples, they learned: Solids keep their shape (like ice cubes). Liquids flow and take the shape of their container (like water). Gases fill spaces and can be felt but not seen (like air in a balloon). Stay tuned for more exciting experiments as our little scientists continue exploring the wonders of science! Objective: The objective of this experiment was to introduce young learners to the three basic states of matter—Solid, Liquid, and Gas—through simple, hands-on activities. The experiment aimed to help students observe, compare, and understand the properties of each state in a fun and engaging way. Materials Used: Ice cubes (Solid) Water (Liquid) Balloon filled with air (Gas) A transparent glass A tray or plate A small fan (to demonstrate air movement) Procedure: 1. Introduction to States of Matter The teacher began by explaining the three states of matter in simple terms: Solid: Has a fixed shape and volume (e.g., ice, books, toys). Liquid: Takes the shape of its container but has a fixed volume (e.g., water, juice). Gas: No fixed shape or volume; fills any space (e.g., air, steam). 2. Observing Solids (Ice Cubes) Students were given ice cubes to hold and observe. They noted that ice is hard, cold, and keeps its shape unless it melts. The teacher explained that when ice melts, it turns from a solid to a liquid. 3. Observing Liquids (Water) Water was poured into different containers (a glass, a bowl, and a bottle). Students observed that water takes the shape of the container but remains the same in quantity. They also saw that when water is heated, it turns into gas (steam). 4. Observing Gas (Air in a Balloon & Fan Demonstration) A balloon was inflated to show that air (gas) fills the space inside. Students squeezed the balloon to feel the air pressure. A small fan was used to show how air moves and can be felt but not seen. Key Observations & Learnings: Solids have a fixed shape (e.g., ice cubes). Liquids flow and take the shape of their container (e.g., water). Gases are invisible but can be felt (e.g., air in a balloon or wind from a fan). Matter can change from one state to another (e.g., ice melts into water, water evaporates into gas). Conclusion: This experiment successfully helped Class 1 students at Ziva Child Care Academy understand the three states of matter in an interactive way. By touching, seeing, and discussing real-life examples, the children grasped the basic concepts of solids, liquids, and gases effectively.
English Activity (Vowel Sound) – L.K.G Class
Introduction: The L.K.G class at Ziva Child Care Academy recently participated in an engaging English Activity focused on vowel sounds (A, E, I, O, U). This interactive session was designed to introduce young learners to the foundational sounds of the English language in a fun and memorable way. Objective: The primary goals of the activity were: To help students recognize and pronounce the five vowel sounds correctly. To associate vowels with common words and pictures. To enhance listening and speaking skills through playful learning. Activity Description: The teachers organized a multi-sensory learning experience with the following steps: Introduction to Vowels: The session began with a short rhyme/song (e.g., “A, E, I, O, U, vowels are fun for me and you!”) to grab the children’s attention. Teachers displayed colorful flashcards with uppercase and lowercase vowels (A, E, I, O, U) and repeated the sounds. Interactive Games: “Vowel Hunt”: Children identified objects in the classroom whose names started with a vowel (e.g., apple, egg, umbrella). “Sound Matching”: Students matched pictures (e.g., ant, elephant, igloo) to the correct vowel sound. Creative Craft: Each child created a “Vowel Collage” by pasting pictures of vowel-based words on a chart. They practiced tracing vowels on sandpaper or textured boards for tactile learning. Group Activity: A “Vowel Circle” game was played where students passed a ball and said a word with the vowel sound called out by the teacher. Outcome: Children enthusiastically participated and improved their ability to distinguish vowel sounds. The combination of songs, visuals, and hands-on activities made learning enjoyable and effective. Parents appreciated the creative approach to phonics instruction. Conclusion: This Vowel Sound Activity successfully built a strong foundation for early literacy skills in L.K.G students. By integrating play with learning, our school ensured that the children remained engaged while mastering essential language concepts.
Science Experiment: Test for Starch Presence in Leaf
Science Experiment: Testing for Starch in Leaves Our young scientists conducted an exciting experiment to discover how plants make their own food! 🌱🔍 Using a simple iodine test, we checked for the presence of starch in leaves—proof that photosynthesis is happening. Plants produce their own food through the process of photosynthesis, where sunlight, carbon dioxide, and water are converted into glucose (sugar). Excess glucose is stored as starch in the leaves. This experiment helps children understand how plants make food and how we can test for the presence of starch using iodine solution. Materials Used: A fresh green leaf (from a plant exposed to sunlight) A pot of boiling water A beaker or small bowl Ethanol (or rubbing alcohol) Iodine solution (Lugol’s iodine or tincture of iodine) Tweezers White tile or petri dish Safety goggles (for children observing) Procedure: Step 1: Selection of Leaf A healthy green leaf was plucked from a plant that had been exposed to sunlight for several hours. Step 2: Boiling the Leaf The leaf was placed in boiling water for 2-3 minutes to soften it and break down cell membranes. Step 3: Removing Chlorophyll The leaf was then placed in a small beaker with ethanol (alcohol) and heated gently in a water bath. The ethanol turned green as chlorophyll was extracted, leaving the leaf pale and brittle. Step 4: Rinsing and Iodine Test The leaf was rinsed in warm water to remove excess alcohol. It was then placed on a white tile, and a few drops of iodine solution were added. Observations: The parts of the leaf that had been exposed to sunlight turned blue-black, indicating the presence of starch. Areas that were covered (if tested with a variegated leaf) remained brownish-yellow, showing no starch. Learning Outcomes for Children: Understanding photosynthesis in a simple, hands-on way. Observing chemical changes (color change with iodine). Developing scientific curiosity and analytical skills. Safety Note: Adult supervision was maintained during boiling and use of alcohol/iodine. Children observed the experiment while wearing safety goggles. Conclusion: The experiment confirmed that leaves produce starch through photosynthesis when exposed to sunlight. The iodine test is an effective way to detect starch, as iodine reacts with starch to form a dark blue-black color.
