Purpose

Students will collaboratively design and construct simple circuits to power small devices, exploring both AC and DC currents. This hands-on project will encourage students to apply critical thinking and problem-solving skills as they navigate real-world electrical challenges. Through self-directed learning, students will reflect on their progress and utilize feedback to enhance their understanding. The experience will foster a sense of identity and belonging as students engage with authentic questions relevant to their communities.

Learning goals

Students will explore the principles of AC and DC circuits by designing and constructing a simple circuit to power a small device, fostering hands-on understanding of electrical concepts. They will engage in self-directed learning, using feedback and reflection to refine their projects, while building self-awareness and confidence. Through critical thinking and problem-solving, students will investigate innovative solutions to real-world electrical challenges, enhancing their sense of identity and belonging within the learning community.
Standards
  • [Texas] 7.13B - describe the hierarchical organization of cells, tissues, organs, and organ systems within plants and animals
  • [Texas] FA.A.MS3.2D - use an understanding of copyright and public domain to appropriate imagery when working from sources rather than direct observation or imagination
  • [Texas] FA.A.MS1.4B - analyze original artworks using a method of critique such as describing the artwork, analyzing the way it is organized, interpreting the artist's intention, and evaluating the success of the artwork
Competencies
  • Self Directed Learning - Students use teacher and peer feedback and self-reflection to monitor and direct their own learning while building self knowledge both in and out of the classroom.
  • Academic Mindset - Students establish a sense of place, identity, and belonging to increase self-efficacy while engaging in critical reflection and action.
  • Critical Thinking & Problem Solving - Students consider a variety of innovative approaches to address and understand complex questions that are authentic and important to their communities.

Products

Students will collaboratively design and construct a simple circuit to power a small device, such as a light bulb or a fan, using both AC and DC currents. They will document their process through a digital portfolio, incorporating images and videos, ensuring proper use of copyright and public domain resources. Additionally, students will create an analysis report critiquing their circuit design, reflecting on their learning process, and proposing improvements. This project will culminate in a class presentation where students share their findings and engage in peer feedback.

Launch

Begin with a hands-on activity where students explore a variety of small devices powered by circuits, such as a flashlight, a small fan, or a toy car. Provide materials for students to disassemble and examine the inner workings, identifying components that use AC and DC currents. Facilitate a discussion where students share their observations and hypothesize how these circuits function. Encourage students to connect their findings to real-world applications, sparking curiosity and setting the stage for designing their own circuits.

Exhibition

Students will showcase their circuit projects in a "Circuit Expo" where they present their working models to peers, teachers, and community members. Each student will create a display board explaining the function of their circuit, the differences between AC and DC currents, and the process they used to build their device. Attendees will have the opportunity to interact with the circuits and ask questions, allowing students to demonstrate their understanding and critical thinking. Students will also provide feedback on each other's projects, fostering a collaborative learning environment.
