Main Curriculum Tie:
Background For Teachers:
Electrical machines include those which use electrical power and would have a plug or use batteries. Classroom examples include an overhead projector, electric pencil sharpener, computer, heat lamp, TV, or VCR.
Intended Learning Outcomes:
Ask students for some examples of heat sources - things that produce heat. Write them on the board. If machines are not mentioned, talk about some machines that also give off heat, even if they are used for something else. Has anyone ever felt the back of a computer? Sometimes that is warm. Light bulbs can get so hot that you could burn yourself if you touched one while it was still on.
Today, we're going to hear a story about a Little Orange Rooster (pdf). While listening to the story, think about all the machines that he and his friends use, and think about if those machines would get warm or not.
Homework & Family Connections
Encourage students to show their family how to make Machine toast (see Assessment Suggestion #2). Each family member must draw a different type of machine, and label it as mechanical or electrical.
