Hey, that's a simple machine!
Play a short video about simple machines, such as the one on BrainPop Jr.
2 Direct Instruction
Ideally students will already be familiar with the types of simple machines before this lesson and you can do a quick review.
3 Guided Practice/Demonstration
Students will be taking a picture of a simple machine in the classroom (or playground) and explaining why the item is a simple machine.
Students will use Explain Everything or a similar app for this activity. You can turn on the simple interface (under settings) in Explain Everything to make the app more friendly for younger users.
Demonstrate to students how to take a picture and insert it into the app. Then show how to annotate and record audio.
4 Independent Practice
Working independently or in small groups, students will identify a simple machine in their immediate surroundings. They will take a picture, insert it into the app, and record audio explaining which simple machine they have found and why it is that simple machine.
Students will share their video explanations with the class. It may be interesting to tally the variety of simple machines found by students or look for patterns in their findings.
