STATES OF MATTER - Distinguir entre las propiedades de sólidos, líquidos y gases. - Saber cómo están unidas las partículas según la Teoría Cinética de las Partículas. - Identificar los distintos cambios de estado y relacionarlos con fenómenos naturales y cotidianos. SESIÓN 1: Reconocimiento de sólidos, líquidos y gases de acuerdo con sus propiedades. Se empieza con una lluvia de ideas motivada por una serie de materiales (bloque de madera, arena, zumo de naranja, agua, aire). alumnos deben deducir sus propiedades (si tienen forma y volumen fijos o no, si se pueden comprimir o no...) que recogen en una tabla. A continuación, se reparten por parejas unas fichas donde un estudiante dice una propiedad y el otro debe decir de qué estado se trata. otra tabla. SESIÓN 2: No siempre es fácil clasificar materiales. Se muestra a los alumnos un esquema con diferentes preguntas que al ir contestando les permite llegar a la conclusión de a qué estado pertenece un determinado material. borrar… los cambios de estado. y los gases.

Solid State of Matter These crystals of the mineral pyrite are a good example of a solid. Click on image for full size Courtesy of Corel Solid is one of the four common states of matter. The three others are gas, liquid, and plasma. There are also some other exotic states of matter that have been discovered in recent years. Unlike liquids and gases, solids have definite shapes. The atoms or molecules in a solid are packed together much more tightly in a solid than in a gas or a liquid. Solids are usually much more dense than liquids and gases, but not always. Many solid materials will melt when heated. Crystals, wood, rocks, most metals, and glass are all examples of common solids. Shop Windows to the Universe Science Store!

Fifth grade Lesson States of Matter Part 1 | BetterLesson Inquiry Based Instructional Model To intertwine scientific knowledge and practices and to empower students to learn through exploration, it is essential for scientific inquiry to be embedded in science education. While there are many types of inquiry-based models, one model that I've grown to appreciate and use is called the FERA Learning Cycle, developed by the National Science Resources Center (NSRC): 1. Focus 2. 3. 4. A framework for implementation can be found here. I absolutely love how the Center for Inquiry Science at the Institute for Systems Biology explains that this is "not a locked-step method" but "rather a cyclical process," meaning that some lessons may start off at the focus phase while others may begin at the explore phase. Unit Explanation In this unit, students will begin by exploring the properties of matter. Summary of Lesson Today, I open the lesson by discussing the three states of matter. Next Generation Science Standards 5-PS1-1. 5-PS1-3. Crosscutting Concepts

Fifth grade Lesson Physical Changes Versus Chemical Changes The Focus of the Investigation: After our foldable is created, it is time to investigate some changes to practice identifying them as physical changes or chemical changes. The students get very excited about some of these activities so it is important to help guide them to help them focus on what is most important, observing the changes that are occurring and watching for one of the indicators listed in the foldable. The Physical and Chemical Change Investigation Sheet that I use for this lesson has students identify properties before and after to help them notice these changes. Investigating in Small Groups: We do the rotations as a class, but each group completes the activities and investigation sheet together. Next, we move to the station 1 activity: Origami. We move on to station 2: Lava Lamps. Station 3 is building a boat out of an 10" x 10" square of aluminum foil. After boats are built, we move on to station 4: Balloon Blow Up. Our final station is station 5: Glue Bouncy Balls.
What is Matter | Matter Facts for Kids Some substances, like glass and water, allow light to pass through them. These substances are called transparent or see-through. The matter is still there, even though it can be hard to see. Humans are very good at changing matter to make things we can use. Gases Gases Gases such as air are the lightest state of matter. Gases › Solids Solids Solids, such as wood and stone, have a fixed shape that is difficult to change. Solids › Liquids Liquids Liquids such as water can flow freely, changing their shape. Liquids › Some matter is bound up in living creatures, such as animals and plants. Earth is mostly made up of nonliving substances such as rock and metal. Changing states Changing states Matter can come in different forms, or states, such as solids, liquids, and gases. Changing states › Atoms › All matter is made up of tiny, tiny particles called atoms. Atoms › Inside an atom › Atoms can be broken down into even smaller particles. Inside an atom › Molecules › Molecules ›
Eighth grade Lesson Eliciting Student Ideas: What is Heat? What is Temperature? This starts a series of lessons that introduce students to Heat and Temperature. I teach these in the context of a my unit on Changes in Earth's Atmosphere in order to apply the understanding of heat transfer on atmospheric phenomena as opposed to stand alone physical science lessons. This set of lessons gets students thinking about how heat is transferred through conduction, convection, and radiation. You begin with an elicit of student's ideas on heat and temperature followed by engaging them in discussion of their ideas. First up is a lesson from the American Chemical Society, where students complete an activity in which heat is transferred from hot water to metal washers and then from hot metal washers to water. A lab modeling the Greenhouse effect looks at heating of soil and water with and without an "atmosphere" as part of an exploration of heat transfer by radiation.

What is Matter? Water is everywhere-even in the air! People describe objects in many ways using size, shape, colors, and textures. Describing objects by using size (place images here) shape color texture uses an object's properties. A property describes how an object looks, feels, or acts. Name one property of the birthday present? Properties of all objects Objects take up space. All objects take up space. Objects have mass. Mass is how much there is of an object. Objects that take up space and have mass are called matter. If you are having trouble understanding matter, look all around you. Let's take this carrot: Let's get closer and closer to the smaller parts of the carrot-carrot atoms! These small parts of the carrot are called atoms. All matter is the same because all matter is made up of atoms. Properties of Matter Remember all objects take up space and have mass. Density is an important physical property. Properties are constantly changing... Matter is constantly changing.
States of matter — Science Learning Hub Anything that has mass1 is made up of matter2 – an all-encompassing word for atoms and molecules3 that make up our physical world. We describe this matter as existing in states (sometimes referred to as phases). Most people are familiar with three states of matter4 – solids, liquids and gases5 – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates. Rights: The University of Waikato Te Whare Wānanga o Waikato Three states of matter Solids, liquids and gases are three states of matter. It is important to understand the particle6 nature of matter. Solid Something is usually described as a solid if it can hold its own shape and is hard to compress (squash). Rights: Foobar, Creative Commons 3.0 Gallium crystal Gallium is an uncommon metal that exists in a liquid and solid form. Right now, you are probably sitting on a chair, using a mouse or a keyboard that is resting on a desk – all those things are solids. Liquid Gas Plasma Lightning
A Matter of State A plastic bottle is compressed following a flight Photo Credit: Korte Purpose To help students understand that particle movement changes as a substance changes from one phase to another phase. Context This lesson is designed to give students the opportunity to observe a phenomenon created by particle movement. Prior to this lesson, students should have been introduced to the notion that matter may go through different phase changes. This particular benchmark may be difficult for students to grasp because middle-school and high-school students are deeply committed to a theory of continuous matter. Additionally, many students do not understand that all substances undergo some type of movement. Emphasis needs to be placed on helping students understand that there are different motions exhibited by substances in their respective phases. Motivation Ask students to write descriptions of the three common states of matter. Development Break the class into lab groups of four to five students.
