As we have learned earlier, the earth has one satellite which is the moon. Scientist have launched artificial satellites (like space shuttle, rockets etc) into space to carry out experiments, collect information and learn more about other space. <h2><strong>Types of Satellites</strong></h2> The types of satellites include the following: <ol> <li>Communications satellites</li> <li>Weather satellites</li> <li>Navigation satellites</li> <li>Surveillance satellites</li> <li>Scientific satellites</li> </ol> <img class="size-full wp-image-36602 aligncenter" src="https://classhall.com/wp-content/uploads/2018/06/communications-satellite.jpg" alt="Satellites - Types of Satellites - Communications Satellites" width="320" height="195" /> <h3><strong>Communications Satellites</strong></h3>

Animals move from place to place. Plant only moves in stationary state towards light, water, etc.</li> <li><strong>Respiration</strong>: This is the taking in of oxygen to release energy as a result of breakdown of food in the body.</li>

<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:

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:
