Overview As an ending activity to our electricity unit, the students designed and built houses complete with working lights. They utilized the concepts taught during this unit to create complete circuits, switches, parallel and series circuits, and included conductors and insulators in the houses. Objectives The students will design electric houses with working lights and switches. The students will work cooperatively to plan and implement house designs with complete circuits, making working lights, and switches. liv es . ® g sc gin hoo l supplies. chan GRADE LEVEL Materials mini light bulbs, 9 volt batteries, D batteries, paperclips, bulb holders, batter holders, wire strippers, wires, brass fasteners, brass fasteners, cardboard boxes, shoe boxes, electrical tape, masking tape, paint, switches, filament, fahnestock clips, wires, variety of materials to use as insulators and conductors, index cards Readiness Activity Making a complete circuit Creating a switch Making parallel and series circuits Identifying parts of a light bulb and parts of a complete circuit Differentiate between conductors and insulators Strategies/Activities Students were taught parts of a light bulb & parts to create a complete circuit. Pupils worked in pairs to create a complete circuit using a wire, battery, and bulb. Next, they created a complete circuit using a battery, wires, battery holder, bulb, battery holder, and light bulb. Students knew if the light bulb did not light that it was not a complete circuit. Students were taught about the usefulness of conductors and insulators. Each student was given a baggie of many items that they could test for conductors/ insulators. THIS WINNING PROJECT IDEA SUBMITTED BY: Mickey Hendricks Fort Washington Elementary School Washington, PA 4 5 WEEKS $500 TOTAL BUDGET Electrical Houses ....continued.... Students used their circuit tester (bulb, bulb holder, batter, battery holder, wires) to see if the item was a conductor or insulator. If the light bulb lit, the item was a conductor. If it did not light, it was an insulator. Students created series circuits and parallel circuits and were able to identify how they were similar and different. They could determine their usefulness as well. Pupils created a handmade switch using index cards, a paper clip, brass washers, brass fasteners, and fahnestock clips. After performing all of these lessons, students worked with partners to design and construct electric houses with working lights and switches. Culminating Activity The culminating activity for this unit was to work with a partner to construct a working electric house. Each house included working lights and two homemade switches. Teams worked together to create a theme surrounding their house. Houses were displayed for parents for Open House, and other classes came to view the electric houses. Evaluation Method Students were given an end of chapter assessment on the material covered in our electricity unit. Students were graded using a rubric on their electric houses. Students graded themselves using a self-assessment rubric on their houses and cooperative working skills. Electricity notebooks were collected and graded using a checklist scoring guide.
