Is an ice cube matter? It takes up space, it has mass, and it has properties. You discovered that air is matter. Water is also matter. Matter is found in different forms. A book, water and air in a balloon are examples of states, or forms of matter. The book is an example of solid matter because it has a definite shape. It takes up a certain amount of space. All matter is made up of small particles. In a solid object the particles atoms, are packed closely together. http://www.educents.com/complete-curriculum STUDENT MANUAL FOURTH GRADE SCIENCE / LESSON 5 Now, if you leave the ice out at room temperature it will change into a liquid. The particles in the ice begin to move away from each other and it no longer has a definite shape. It takes the shape of its container. It still has a definite amount of space no matter what container it is in. What will happen when water is in a pan and heated? If the water is boiled, the water will disappear into a vapor, which is called a gas. Gas does not have a definite shape. It does not take up a certain amount of space. It will spread all over in the air. Take a piece of plain white paper. Lesson Wrap-Up: Discuss the three states of matter. http://www.educents.com/complete-curriculum STUDENT MANUAL FOURTH GRADE SCIENCE / LESSON 5 Lesson 5 The States of Matter NAME: _________________________________________________________________ DATE: __________________________________________________________________ Directions: Use your digital tools Draw a book and next to it draw a circle. Fill the circle with as many dots as you can. The dots should actually touch each other. Draw a fish bowl full of water with a circle next to it. You will make the dots in this circle just slightly apart from each other; not touching. Draw a balloon with a circle next to it. In this circle make dots randomly far away from each other. Your circle for the book represents particles that make up the matter of a solid object. Your dots in the circle are close together because it is a solid. Your circle for the water represents particles that make up the matter of a liquid. Your dots in the circle which are close but not touching are molecules for a liquid. Your circle for the vapor of water that is far apart represents a gas. Your dots are moving around and there is not a definite shape, which are molecules for gas. http://www.educents.com/complete-curriculum STUDENT MANUAL BOOK FISH BOWL FOURTH GRADE SCIENCE / LESSON 5 http://www.educents.com/complete-curriculum STUDENT MANUAL BALLOON FOURTH GRADE SCIENCE / LESSON 5
