SEEDS After School Lesson Plan Instructor: Marc Alderman Number of Youth: Activity Name: Squishy Circuits Zoo 6-24 4th graders Date(s): 6/25/14 Objectives *All students will create a Squishy Circuit animal sculpture that will successfully light up LEDS and/or power a DC motor. Outcomes (include any educational standards addressed) Michigan GLCE P.EN.04.51 Demonstrate how electrical energy is transferred and changed through the use of a simple circuit. P.EN.04.12 Identify heat and electricity as forms of energy. P.PM.04.53 Identify objects that are good conductors or poor conductors of heat and electricity. National Visual Arts Standards 4th grade *Brainstorm multiple approaches to a creative art or design problem *Collaboratively set goals and create artworks that are meaningful and have purpose to the makers *Create works of art that reflect community cultural traditions Time and Content One 90 minute session as an extension of “Electric Scientist” lesson SESSION #1 (complete this section as many times as needed) Preparation -Make a sample Squishy Circuit animal using 2 LEDS and a DC motor -mix Squishy Circuit conductive dough http://courseweb.stthomas.edu/apthomas/Squ ishyCircuits/conductiveDough.htm -mix Squishy Circuit insulating dough http://courseweb.stthomas.edu/apthomas/Squ Materials -4 AA batteries per student or per student group -1 AA battery case per student or per student group -Squishy Circuit conductive dough -Squishy Circuit insulating dough -Variety of LEDS 5mm-10mm ishyCircuits/insulatingDough.htm *Note you can also make the dough with the students as a lesson on measuring, consistency, materials, and following directions Activity Steps 1. Intro Tell the students that today we will be making a Squishy Circuit Zoo. Ask them to think of an animal that has personal meaning to them or their family. Then ask them to share their name, the animal they chose and why. For example. My name is Marc. I chose a bobcat because that is the Brethren school mascot. 2. Review Ask the students to recall some of the take aways from their classroom lesson “Electric Scientist”. You should cover: -conductive -insulating -how to light an LED -how use a battery (or batteries) to power the simple circuit -short circuit 3. Project Directions a. Show the students your pre-made example Squishy Animal. b. Show that the body is made of a core of insulating dough around the DC motor. c. Show how the “skin” of the animal covers the body and one of the DC motor terminals. d. Put two LEDS into a lump of insulating dough and bend the negative (short) leg to a 90 degree angle. These are the eyes. e. Wrap conductive dough around the LED/insulating dough touching just the negative legs. This is the head. f. Add a small ball of conducting dough to the exposed connection of the DC motor making sure it only touches the insulating dough around it. g. Attach the head to the body making sure that the positive legs of the LEDS touch the -3v-6v DC motor per student or per student group -safety glasses 3b. 3c. 3d. 3e. ball of conductive dough you added in step f and the head touches the body to complete the circuit. h. After putting on safety glasses, power the Squishy Circuit Animal with a positive lead to the small ball added in step f and the negative lead to any part of the conductive dough covering the body. i. After testing the electrical connections the students may sculpt the animal adding features like ears, eye sockets, a mouth, a tail, claws, whiskers, or any other traits appropriate to the animal being modeled. j. Put on safety glasses, turn on the power, and watch the tail move and the eyes light up! 4. Wrap Up a. Place the Squishy Circuit Zoo Animals on display with the student’s name and the name of the specie of the animal on a label. b. See student reflection. 3f. 3g. Student Reflection Have the students sketch their Squishy Circuit Zoo Animal in their Electric Scientist Journal they made in class. Have the students write two or three frustrations they encountered and two or three triumphs they experienced during the project. ____________________________________ Instructor Reflection 3i.
