Upon completing this lesson the students will:
• Develop models to illustrate and explain that energy can be transferred from place to place by electric currents and that electric currents flowing through a simple circuit can be used to produce light;
• Understand the difference between series, and parallel circuits;
• Construct explanations of how some materials allow electricity to flow through a circuit and some do not; and
• Understand the difference between conductive material and insulating material.
1. How are electrical circuits created?
2. What does it mean for a material to be conductive? Insulating?
Other Instructional Materials or Notes:
• Battery Packs and Batteries with Leads
• Conductive Dough
• Insulating Dough
• LEDs (should be appropriate for the source voltage)
Optional, but recommended:
CONDUCTIVE DOUGH RECIPE – http://youtu.be/cpUFL5LZpv4
1 Cup Water (tap) • 1 1/2 Cups of Flour • 1/4 Cup of Salt • 3 Tbsp. of Cream of Tartar • 1 Tbsp. Vegetable Oil Food Coloring (optional)
INSULATING DOUGH RECIPE – http://youtu.be/Wz8rGNt-iEQ
• 1 1/2 Cup of Flour • 1/2 Cup of Sugar • 3 Tbsp. of Vegetable Oil • 1/2 Cup of De-Ionized (or distilled) Water • 1 tsp. of Granulated Alum (optional)
- 3.P.3 The student will demonstrate an understanding of how electricity transfers energy and how magnetism can result from electricity.
- 3.P.3A Energy can be transferred from place to place by electric currents. Electric currents flowing through a simple circuit can be used to produce motion, sound, heat, or light. Some materials allow electricity to flow through a circuit and some do not.
- 6.P.3 The student will demonstrate an understanding of the properties of energy, the transfer and conservation of energy, and the relationship between energy and forces.
- 6.P.3A Energy manifests itself in multiple forms, such as mechanical (kinetic energy and potential energy), electrical, chemical, radiant (solar), and thermal energy. According to the principle of conservation of energy, energy cannot be created nor de...
