Non-living Things: Matter
<h1><strong>NON-LIVING THINGS - MATTER</strong></h1> CONTENT <ol> <li>The Meaning of Matter</li> <li>Identification of Matter</li> <li>States of Matter</li> <li>Change of State of Matter</li> </ol> <h2><strong>Meaning of Matter</strong></h2> Matter is anything in nature that has mass and occupies space. Stone, paper, plant, animal, air, water, rubber etc. are made up of matter. Matter is made up of small particles called atoms. <p style="text-align: center;"><img class="size-full wp-image-32420 aligncenter" src="https://classhall.com/wp-content/uploads/2018/06/non-living-things-matter.jpg" alt="Non living things - Matter" width="448" height="201" /><strong>Water Droplets</strong></p> <p style="text-align: left;"><span style="color: #008000;">Water droplets are made of water molecules that bond together.</span></p> <h2><strong>Identification of Matter</strong></h2> Matter is classified into solid, liquid, and gas. All living and non-living things are made up of matter. It means that everything that you can see, touch, smell, breathe or eat is made up of matter. Matter can be classified as living and non-living matter. Can you mention some living and non-living matter around you? <h2><strong>States of Matter </strong></h2> The three states of matter are Solid, Liquid and Gas. Hence, we have solid state, liquid state and gaseous state. Matter can be classified into the following groups:
Relationship between Organisms in a Habitat
<h1><strong>RELATIONSHIP BETWEEN ORGANISMS IN A HABITAT</strong></h1> CONTENT <ol> <li>Biotic and Abiotic Factors</li> <li>Population</li> </ol> <h2><strong>Biotic and Abiotic Factors</strong></h2> Organisms in their habitats are affected by many factors. Factors are the things or conditions that influence their livelihood. These factors are called <strong>biotic</strong> and <strong>abiotic </strong>factors. Biotic factors are the living factors of the habitat such as the living things found in that habitat while the abiotic factors are the non-living factors in the habitat such as oxygen, temperature, dissolved salt, water, sun light, etc. The biotic factors are classified as producers, consumers and decomposers.

Classification of Non-living Things: Metals and Non-metals

Examples are copper, iron rod, empty cans, aluminum, silver, gold, lead etc. <img class="size-full wp-image-32424 aligncenter" src="https://classhall.com/wp-content/uploads/2018/06/metals-and-non-metals.jpg" alt="Classification of non living things - Metals and non metals" width="316" height="147" /> <p style="text-align: center;"><strong>Copper-Coated Pennies</strong></p> <span style="color: #008000;">Most coins used the United States contain copper. Pennies, <em>shown here,</em> are made of zinc with a thin coating of copper. They actually have less copper than other U.S. coins!</span> <h3><strong>Properties of Metals</strong></h3> The following are the properties of metals:
Nutrient Cycle, Food Chain and Food Web
<h1><strong>NUTRIENT CYCLE, FOOD CHAIN AND FOOD WEB</strong></h1> CONTENT <ol> <li>Meaning of Nutrient Cycle in Nature</li> <li>The Water Cycle</li> <li>Nitrogen Cycle</li> <li>Carbon Cycle</li> <li>Food Chain</li> <li>Food Web</li> </ol> <h2><strong>Meaning of Nutrient Cycle in Nature</strong></h2> <strong>Nutrient Cycle in Nature</strong> is the constant circulation of nutrients around the ecosystem. Photosynthesis and respiration drive the movement of oxygen and carbon dioxides to become available all the times. <h2><strong>The Water Cycle</strong></h2> We use water every day, where does water comes from, water is found almost everywhere in different forms. Water cycle is the continuous movement of water, from land, rivers and oceans to the atmosphere as vapour and from atmosphere back to land and rivers or oceans as rain.
