TE 407: Lesson Plan and Report # 2 Name: Dan Winther Mentor Teacher: Ann Fritts Date: 12/4/07 Partner: N/A School: Williamston Middle School Part I: Information about the Lesson or Unit Topic: Subject: Earth Science Unit Topic: Earth’s Air and Atmosphere Lesson Topic: Heat Transfer in The Atmosphere Type of Class Grade level(s): 7 Type of school: Suburban Tracking level: Untracked Abstract The lesson will begin with the Bell Ringer, as usual. After the students share their ideas, we will review with a diagram of radiation from the sun (a transparency). I will open up the room for discussion about the diagram, and since the students have already learned about radiation a bit, their ideas will segue into the lesson of heat transfer and the atmosphere. In order to teach the three types of heat transfer, I will rely on giving the students plenty of examples of each, and then give bigger examples at an “atmospheric” level. To accompany the lesson, I will have the students complete a worksheet individually. I will make sure to leave time at the end for students to answer the questions as a group, to make sure they understand the material Part II: Clarifying Your Goals for the Topic Knowledge: Big Ideas The Greenhouse Effect, water cycle, and global warming are all phenomena that occur within, and often because of, the Earth’s atmosphere. Many of the processes that occur within the atmosphere (including those listed above) are due to the unequal heating of the Earth’s atmosphere. Solar radiation is what scientists refer to as a form of heat transfer. Along with radiation, convection and conduction are also forms of heat transfer that occur in the atmosphere. Radiation is emitted in the atmosphere from the sun in the form of waves or rays. The radiation from the sun either enters the lower atmosphere and is re-emitted from the surface, or can be re- emitted by things in the atmosphere such as clouds. Convection occurs when heat is transferred through the air, and it also causes convection currents. Conduction occurs when heat is transferred by touch, much like when you touch a hot pan and it burns. All of these heat transfers occur within the atmosphere, and are the major cause of weather. Knowledge: Experiences, Patterns, and Explanations Initial Student EPE Goal EPE Observations or experiences (examples, phenomena, data) Patterns (laws, generalizations, graphs, tables, categories) Touching a hot stove or pot will hurt We can feel air moving when it’s windy outside Earth’s atmosphere is warmed by the sun When you touch a hot pan, heat is transferred from the pan to your hand Solar radiation warms the earth’s atmosphere When we heat our house, heat is transferred to the air from the heater We can feel air moving when it’s windy outside, which is caused by some atmospheric phenomena Heat is transferred in different ways Solar energy is a major player in the heat that we know Solar energy radiates through out atmosphere, and warms the air Heat can travel in many different ways through mediums Weather (wind, etc.) is caused by heat transfers Explanations (models, theories) There are three types of heat transfers (convection, conduction, radiation) Earth’s weather is caused by heating the atmosphere from solar radiation and convection Application: Model-based Reasoning Inquiry: Finding and Explaining Patterns in Experience Possible Objectives for Student Learning Objective Michigan Objective(s) 1. E.ES.06.42 Describe the relationship between the sun’s warming of the Earth’s atmosphere and convection within the atmosphere and oceans. 2. E.ES.06.43 Describe how the sun’s warming of the Earth produces winds and ocean currents. 3. E.ES.06.45 Describe how different weather occurs due to the constant motion of the atmosphere from the sun’s energy reaching Earth’s surface.

Using SP Part III: Classroom Activities Materials Presentation materials (Overhead transparencies or PowerPoint presentations, etc): Radiation Transparency Copied materials (Handouts, worksheets, tests, lab directions, etc.): Handout on Energy Pages in textbook: Book: Glencoe (Earth Science) Pages: 402-407 Activities Introduction (5 minutes) The class will begin with the usual bell ringer, where the students will pull out their weekly sheets and answer a science question. I will be walking around, making sure that the students are filling out their sheets, and settling the class down for the lesson. After about 2 minutes, I will ask for volunteers to share their thoughts on the question. Students will share, and I will read the actual answer. At this time, I will transition into the beginning of the heat transfer lesson. A transparency will be placed under ELMO, with three accompanying questions. From previous lessons, the students should recall how to answer the questions. The transparency involves solar radiation, one of the three heat transfer processes we will be discussing. Main Teaching Activities (30 minutes) Building from what the students said regarding the transparency problems, we will move into the three types of heat transfer. Using the SmartBoard, I will write the names “Radiation, Convection, and Conduction” on the board, and then move into the first of many examples. I will bring the classes attention to the terrarium in the back of the class, where I will the students a multitude of questions, including “Why is the terrarium placed by the window?”, “What does it need the light from the sun for?” and “Is there heat transfer occurring in the terrarium? If so, what type of heat transfer do you think it is?”. These questions will help the students to relate to what is going on during solar radiation, and from that, I will introduce them to solar radiation on a bigger scale. They already know about solar radiation from the Water Cycle unit, as well as the Global Warming unit we just finished in class. They will be able to connect how heat transfer from the sun affects these processes, just like it affects the terrarium in the classroom. Once the students begin to grasp the first heat transfer process, I will move on to conduction and convection. The activities will be much like those for the solar radiation, showing them an example that they are familiar with, and then connecting that example to the bigger picture (earth’s atmosphere). By using what the students know already, it will be much easier to teach them this “new” material. The students will hopefully see that the material is not actual 2/16/16, Page 3 something “new”, the lesson just builds on their previous understanding of it, implementing vocabulary to describe the phenomena, as well as more information about each heat transfer process. The lesson will move from describing the three heat transfer processes into how these three affect the atmosphere, touching on how air is moved in the atmosphere. This will provide for a good lead in to the next topic, which will be more focused on earth’s weather. After some probing questions, where I see what the students think about how this connects to air movement and weather, I will move the lesson to a time for student work. A worksheet will be handed out to each student, and also placed under ELMO so the students can see exactly what is expected of them. After reading the directions to the students, and completing the first question as a “group”, I will tell the students to “Begin”, which signals them to start their work for the day. The worksheets will be the assessment for the lesson, much like last lesson. Conclusion (5 minutes) The students have a guest speaker on the day of the lesson, so the lesson has to be much shorter than regularly planned. Therefore, in the last 5-7 minutes, I will go over the worksheet with the students to give them the correct answers, and then collect the worksheets from the students. At this time, the students will clean up their areas, and do whatever procedures necessary to prepare for the guest speaker. Part IV: Assessment of Focus Students Focus Objective Describe the three processes of heat transfer, including conduction, convection and radiation. Developing Assessment Tasks The main assessment task for the lesson is the worksheet the students must complete individually and turn in at the end of the period. From this, I can pick the questions that focus on the above objective, and get a sense for what the students learned/did not learn from the lesson. Like I did for lesson one, I can use the data to compile some statistics on the students learning, and can then compare the statistics of each of the three focus students. However, the worksheet is not the only form of assessment embedded in the lesson plan. When I ask the students questions regarding what they think is going on in the examples (i.e. the heat transfer in the terrarium, or the heating of a pan that can burn), I will attempt to call on each focus student at least once, to not only engage the student, but to gauge what the student may have previously learned or is thinking about the topic of heat transfer. Having two forms of assessment will give me a more concrete idea of what the student is understanding, as well as what areas where they need more help. 2/16/16, Page 4 In lesson one, I wish I had had some post-assessment activity, where I went over problems where many students had problems. Therefore, in this lesson I will be implementing such a postassessment. The following Monday, I will place an additional “Bell Ringer” on the board for the students to think about and answer, and will ask for volunteers to answer the question. After I guage what the students remembered from the lesson on Friday, I will place the “problem” questions under ELMO, and go over the questions with the students again. If the students did not understand the information the first time, hopefully by reviewing and giving them even more help with heat transfer, they will move to an area of understanding. 2/16/16, Page 5
