![]() ![]() ![]() Finally, attach the free end of the second alligator clip to the negative terminal of the battery to complete the circuit.Take another alligator clip and attach one end to the other side of the light bulb holder's conducting material.Then, take the other end of the clip and attach it to one side of the light bulb holder's conducting material (typically this is another piece of metal).Attach one end of an alligator clip to the positive terminal of a battery.Screw the light bulbs into the light bulb holders.īuild a simple circuit using one battery, two alligator clips, and a light bulb. Have students each take out a light bulb from the string of lights to see how current flows to the light bulb through the metal wires on the side of the light. Refer to the associated lesson for background information to help with this. Plug the string of lights into an electrical outlet and explain how electrical current flows through the circuit to make the lights work. 1 light bulb holder per light bulb available at electronics stores or online at Introduction/Motivation.2 to 3 light bulbs per group, whatever size fits into the light bulb holder.1 alkaline lantern battery per group, 6 volt size.1 set of Christmas lights (a string of lights).Understand forms of energy, energy transfer and transformation and conservation in mechanical systems. Recognize that energy can be transferred from one system to another when two objects push or pull on each other over a distance (work) and electrical circuits require a complete loop through which an electrical current can pass. Recognize the basic forms of energy (light, sound, heat, electrical, and magnetic) as the ability to cause motion or create change. Recognize how energy can be transferred from one object to another. ![]() International Technology and Engineering Educators Association - Technology People's needs and wants change over time, as do their demands for new and improved technologies. Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account. The success of a designed solution is determined by considering the desired features of a solution (criteria). Possible solutions to a problem are limited by available materials and resources (constraints). This activity focuses on the following Three Dimensional Learning aspects of NGSS:ĭefine a simple design problem that can be solved through the development of an object, tool, process, or system and includes several criteria for success and constraints on materials, time, or cost.Īlignment agreement: Thanks for your feedback! Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.Ĭlick to view other curriculum aligned to this Performance Expectation ![]()
