Estados De La Materia

GOALS
1. Understand the characteristics of the three states of matter.
2. Identify that liquids cannot be compressed.
3. Describe how a gas can be compressed and observe how it expands.INTRODUCCIÓN

INTRODUCTION

Matter is anything that takes up space and weight! The states of matter include; solid, liquid, gas, plasma and Bose-Einstein Condensate.
All states of matter aremade up of atoms. An atom is like a building block. It makes up everything you see! Each state of matter has different patterns of atoms. The different patterns of atoms are what make the states ofmatter so much different than each other.

MATERIALS

1 test tube | 1 syringe | 1 Tiny beaker | 4 balloons |

EXPERIMENTAL DEVELOPMENT

SOLIDS
Its molecules are closely packed in an orderly arrangement due to very strong forces of attraction between particles. In this statethe solid has a definite shape and volume too.

1. Place under the microscope a few grains of salt.
2. Observe and describe the crystal structure.

What is a crystal structure?
Thispicture shows the observed under microscope.



LIQUIDS
Its molecules are in a disorderly arrangement, liquids have no fixed shapes, they can flow and take theshape of their containers and liquids cannot be compressed.

1. In order to demonstrate that liquids take the shape of the container, measure 200 ml of hydro gel beads in a graduated cylinder,then place the content in the flask and watch how the molecules are arranged and they take the form of container that contains.

Analogy between the hydro gel beads and molecules of a liquid, in...
