Sponge Arrange the three states of matter from that which has the fastest moving atoms to that which has the slowest moving atoms. Arrange the three states of matter from that which has the fastest moving atoms to that which has the slowest moving atoms.

Three Ways to Heat Matter I can define conduction, convection, and radiation. I can summarize the main idea of today’s lesson and suggest examples that illustrate each concept.

Conduction Conduction The flow of energy from one object to another by direct contact between the objects. The flow of energy from one object to another by direct contact between the objects. It occurs when faster-moving particles in the warmer object strike the slower-moving particles near them in a cooler object. It occurs when faster-moving particles in the warmer object strike the slower-moving particles near them in a cooler object. What does the saying, “It’s so hot out, you could fry an egg on the sidewalk!” mean? What does the saying, “It’s so hot out, you could fry an egg on the sidewalk!” mean? Do you think this would be possible? Do you think this would be possible? Remembering Remembering Activity: Ice cube in hand Activity: Ice cube in hand Would you want your home heated by conduction? Why or why not? Would you want your home heated by conduction? Why or why not? Examples of conduction. Examples of conduction.

Conductors and Insulators Conductors: Substances through which energy flows easily. Conductors: Substances through which energy flows easily. Examples: Most metals Examples: Most metals Insulators: Substances though which energy does not flow easily. Insulators: Substances though which energy does not flow easily. Examples: Fur, wood, plastic Examples: Fur, wood, plastic Activity: Comparing insulators and conductors Activity: Comparing insulators and conductors Think of a conductor and an insulator you have used. Think of a conductor and an insulator you have used.

Convection Liquids & gases Liquids & gases When matter is heated, it expands. In a liquid or gas, this expanded matter is less dense than cooler matter, so it rises, carrying its energy with it. Denser, cooler matter sinks. When matter is heated, it expands. In a liquid or gas, this expanded matter is less dense than cooler matter, so it rises, carrying its energy with it. Denser, cooler matter sinks. This creates a circular current. This creates a circular current.

Radiation The transfer of heat from one place to another without the use of matter. The transfer of heat from one place to another without the use of matter. Radiant energy happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up. When the molecules of that object speed up, the object becomes hotter. Radiant energy happens when heat moves as energy waves, called infrared waves, directly from its source to something else.

Get it, Got it, Good!!! You will complete a computer activity where your knowledge of the three ways matter can be heated will be key. Get a computer, go to my wiki, click on “Surveys”, click on the link under the title “Three Ways to Heat Matter”, and complete the activity by following the directions on the site. You will complete a computer activity where your knowledge of the three ways matter can be heated will be key. Get a computer, go to my wiki, click on “Surveys”, click on the link under the title “Three Ways to Heat Matter”, and complete the activity by following the directions on the site. When you have completed the computer activity. You are going to compose a poem about the three ways to heat matter. Start each stanza with one way to heat matter. Include information about how heat is getting to and passing from particle to particle. Use the information you took for notes!! Use examples to show what you are talking about. You must have four stanzas (an introduction and one for each way to heat matter) and include at least four sentences in each stanza. When you have completed the computer activity.

4321 Each stanza has information about matter that is important to understand how heat moves from one substance or particle to another. Facts are scientifically precise. Each stanza has information about matter that is somewhat important to understand how heat moves from one substance or particle to another. Facts are scientifically accurate. Each stanza has information about matter that is loosely needed to understand how heat moves from one substance or particle to another. Facts are somewhat accurate, but missing a piece of information. Stanzas have fragmented thoughts and missing important information about how matter is heated. The facts are not scientifically accurate. Scientific language used accurately (perfectly) and precisely (exactly) to communicate concept. Scientific language used ordinarily to communicate concept. Scientific language used incorrectly to communicate concept. Scientific language not used to communicate concept. The examples are specifically related to the concept and original. The examples are related to the concept and teacher given. The examples lack detail and are loosely related to the concept. The examples are not related to the concept. Misconceptions are evident. The introduction relates the topic to the importance of real-life knowledge for heating matter. The introduction somewhat relates the topic to the importance of real-life knowledge for heating matter. The introduction loosely relates the topic to the importance of real-life knowledge for heating matter. The introduction does not relate the topic to the importance of real-life knowledge for heating matter. The writing is of high quality. It has few to no spelling or punctuation errors and it is written very neatly. The writing is good quality. There are a few spelling and punctuation errors and it is written neatly. The writing is acceptable, but lacks effort. There are many spelling and punctuation errors and it is written messily. The writing is poor and barely legible. It is riddled with spelling and punctuation errors.
