Lesson: Edison and Bell
· Thomas Edison invented the incandescent light bulb.
· Thomas Edison forever changed the way people do work at night, and was the one of the first scientists to harness the power that electricity can have.
· Thomas Edison and his inventions made it possible for all technologies that we have today such as T.V.s, radios, computers, etc. to function.
· Alexander Graham Bell invented the telephone.
· Alexander Graham Bell changed the way we communicate. No longer did people have to send telegraphs or mail, they could call people and talk to them instantly.
Essential Question: “How the invention of the telephone and the light bulb change the way that people live their lives?”
Vocabulary: light bulb, Thomas Edison, Alexander Graham Bell, invention, telephone
Assessment: T will assess the writing prompts to see if the Ss truly grasped how Alexander Graham Bell and Thomas Edison changed the way people lived.
Opening (10 minutes):
· At the start of the lesson, T will put the following starter on the board: “What do you think the most important invention was of all time?”
· T will have the Ss discuss the starter with groups.
· T will ask the Ss to share out their starter.
· T will explain the objective for the day: By the end of the lesson, SWBAT explain what Thomas Edison, and Alexander Graham Bell invented, and how these inventions change the way people lived.
· Ss will write down their starter.
· Ss will share their ideas with their tablemates
· Ss will share their ideas with the class.
Introduction of New Material (20 minutes):
· T will tell the Ss that they are going to do a gallery walk to learn about two prolific inventors (Thomas Edison, and Alexander Graham Bell).
· T will explain how the gallery walk will work.
· T will tell the Ss that each table will have one of two inventors that we are going to learn about today.
· T will explain that once the Ss are done with that part of the gallery walk they are to go to the next designated station.
· T will tell the Ss that part of the gallery walk includes a video that will be shown at the end of the gallery walk when the two stations are completed (technology).
· T will tell the Ss that a graphic organizer will be filled out during the entire walk.
· T will monitor the Ss as they complete the gallery walk.
· Ss will complete the graphic organizer during their gallery walk.
· Ss will complete the gallery walk quietly and respectfully.
· Ss will ask the T questions if any arise.
· Ss will complete the writing prompt quietly.
Guided Practice (15 minutes):
· T will then show a brief PowerPoint on Thomas Edison and Alexander Graham Bell.
· T will emphasize that both of these inventors changed the way that people lived at the start of the 20th century and the way we live today.
· T will emphasize that Alexander Graham Bell made communication a lot easier. People no longer needed to send telegraphs or mail to get in contact with someone. They could now call someone. This saved time, and revolutionized how we communicate with each other.
· To emphasize the effect that Bell had on the world, T will give model two different ways to communicate and ask the Ss which way is quicker and easier. T will first hand out a letter and make the class pass it until it gets to the final person in the class. Then, T will pretend he is calling the class, and instantly tell the class the same message. T will then ask the Ss to analyze why the telephone was such an important invention.
· T will stress that Thomas Edison not only invented the practical light bulb, but a lot of other big inventions that including 1,093 patents. He was a huge influence on research. Light bulbs changed how we work. No longer were people restrained to the daytime for working, they could now work at night.
· T will have the Ss fill out another part of their graphic organizer during the brief Power Point.
· Ss will listen to the PowerPoint
· Ss will fill out the graphic organizer
· Ss will ask questions about the PowerPoint.
Independent Practice (35 minutes):
· T will ask tell the Ss that they are going to start a two-day project involving inventing a new machine that would make life easier for human beings.
· T will tell the Ss that the first part of the project is to fill out a brainstorming graphic organizer that will ask them leading questions about the proposed invention.
· T will hand out the differentiated graphic organizer.
· T will tell the Ss that today they will be writing about their proposed invention, while the next day will be spent drawing and coming up with a final product of the invention.
· T will spend a good amount of time brainstorming as a class some inventions.
· T will stress that their invention should try to better mankind.
· T will ask the Ss if they have any questions.
· T will pull aside the Ss that are following behind to review the gallery walk and help them create an invention of their own (remedial).
· T will explain that after they get done with the first part of the invention project to work on the following writing prompt: “How did Thomas Edison and Alexander Graham Bell change the world that we live in today? What might the world look like if they never invented some of the stuff that they did? Finally, do you think the world is a better place or worse place because of these inventions; explain!”
· Ss will complete a graphic organizer about their inventions.
· Ss that are struggling will work with T to complete the graphic organizer.
Closing (10 minutes):
· As a T will ask the Ss to either read or describe what they wrote in their writing prompts.
· T will tell the Ss that they are going to continue their invention project the next lesson.
· T will introduce that project.
· T will remind the Ss of their homework – their inventor projects.
· T will ask the Ss if they have any last minute questions.
· Students will answer questions.
· Students will ask any last minute questions.
Homework: Social Studies project on the technical innovations at the turn of the 20th century
Materials: LCD, Graphic Organizer, Invention Project (in-class), Invention Project (Homework), Writing Prompt
Overall, the students enjoyed this lesson because they liked moving around during the gallery walk and later in class, having the opportunity to begin to design their own inventions. That particular in class project requires the students to think outside of the box, so I found it particularly helpful to take a couple moments and brainstorm as a class. This helped get the ideas flowing for my students. In addition, I made this a two-day project because it is relevant to the next lesson (also on inventors).
