LESSON PLAN Student Teacher Joshua Smyth Key Learning Area(s) Grade Science & Technology 4, 5 & 6 Date 14 May 2009 Time Focus of lesson: To continue previous lesson on static electricity with biggest static electricity charge of all ‘lightning’ and to introduce and gain an understanding of lightning strikes. Syllabus Outcome(s) Indicators of Learning (List up to 3) PPS2.4 Identifies various forms and sources of energy and devises systems that use energy. Understands a theory of why lightning strikes. Identifies types of lightning strikes. PPS3.4 Identifies and applies processes involved in manipulating, using and changing the form of energy. Gains an understanding of lightning strikes. Links with Previous Learning Continuation of previous static electricity lesson. PPS1.4 Identifies and describes different ways some forms of energy are used in the community. PPS2.4 Identifies various forms and sources of energy and devises systems that use energy. Assessment Understands possible causes of a lightning strike. Identifies the various types of lightning strike. Sequence of Teaching/Learning Experiences Introduction Gather students to open area with a clipboard and pencil and introduce continuation of static electricity lesson and hand out lightning worksheet. Time 2 mins Resources / Organisation Brown Paper Bags Interleaved phonebooks Body Have the following questions written on the whiteboard: 1. Where does lightning usually strike? 2. Why is it hard to study lightning? 3. Why does lightning strike? 4. How do you stay safe when lightning is about? 5. What are some types of lightning? Lightning images on thumb drive Lightning strikes youtube clip Introduce the biggest static electricity charge – lightning. Discuss with students what they see when lightning strikes and get them to draw it on the worksheet. 3 mins Conduct lightning experiment. Get a volunteer to inflate 2 brown paper bags and explode it together. Explain to students that this is one theory of why lightning strikes as a result of friction. Get 2 students to try to pull apart interleaved phone books that are held together by friction. 5 mins Get students to estimate temperature of lightning then move to computer to show images of lightning and get students to discuss what they see in the images. Give more details after the students have spoken if appropriate. 10 mins Watch you tube video on lightning strikes. http://www.youtube.com/watch?v=2wY_t7zVIXY 10 mins Students to fill out lightning fact sheet. 10 mins Conclusion Discuss answers to the questions and reveal the temperature of a lightning strike. 5 mins Lightning worksheet Assessment and Evaluation after Teaching Evidence of student learning (how do you know that students have learned the skills and understandings taught) Students are able to identify types of lightning strikes. Students are able to answer the six questions posed and understand the difficulties of studying lightning and understand at least one theory of why lightning strikes. Critical evaluation of your teaching (Evaluate two or three key aspects) This lesson showed me why teachers need eyes in the back of their head. When showing the lightning pictures to the students, two students left the group and went to fill out the answers to the questions on the worksheet. I should have noticed this immediately and scanned the room after each image. The guessing of the temperature was good to tie the lesson together and an appropriate conclusion. However many students answered very, very, very, very hot. After the first student gave that response I should have asked the rest of the class who else thought that to put their hand up to save time going through the class. Lightning images and youtube video were appropriate as the students enjoyed and watched attentively. The 2 students who went off to answer the questions stayed when they came back and saw the quality of the images. Whiteboard writing was much clearer. I must ensure that I maintain high standards as a good example to the students. Links with further learning PPS2.4 Identifies various forms and sources of energy and devises systems that use energy. PPS3.4 Identifies and applies processes involved in manipulating, using and changing the form of energy.
