In this engineering design activity, students will investigate radiant energy and the concept of refraction in order to develop a natural lighting system made from recycled water bottles.
1-PS4-2 Make observations to contruct an evidence-based account that objects in darkness can be seen only when illuminated. Clarification Statement: Examples of observations could include those made in a completely dark room, a pinhole box, and a video of a cave explorer with a flashlight. Illumination could be from an external light source or by an object giving off its own light. Assessment Boundary: none
This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation Expound on Step 1 in the Research and Gather Information section of the lesson plan. Try to give students an experience with as little or no light possible. They will revisit this idea later in the lesson with a pinhole box.
This resource is explicitly designed to build towards this science and engineering practice.
Comments about Including the Science and Engineering Practice Be sure to allow students time to go through each of the prescribed engineering design steps, as described in the lesson, to engage in the full practice. Have students talk about their own experiences with the phenomena to understand their preconceptions and so they can compare them with their observations in the activity.
This resource appears to be designed to build towards this disciplinary core idea, though the resource developer has not explicitly stated so.
Comments about Including the Disciplinary Core Idea To meet the full expectation of the Disciplinary Core Idea, provide students with additional opportunities to observe and investigate with objects that give off their own light in completely dark spaces e.g. a battery-operated tea light in a shoebox with a pinhole in one end for them to look through.
This resource is explicitly designed to build towards this crosscutting concept.
Comments about Including the Crosscutting Concept Allow enough time for students to design, test, and redesign their devices. Require students to justify their designs and allow for modifications when needed, so students can make strong connections between the cause and effect of design modifications on their product.
