Students work together to build knowledge around the behavior of light. They discover that light will pass through, not pass through, or reflect off of certain objects.
1-PS4-3 Plan and conduct investigations to determine the effect of placing objects made with different materials in the path of a beam of light. Clarification Statement: Examples of materials could include those that are transparent (such as clear plastic), translucent (such as wax paper), opaque (such as cardboard), and reflective (such as a mirror). Assessment Boundary: Assessment does not include the speed of light.
This resource appears to be designed to build towards this performance expectation, though the resource developer has not explicitly stated so.
Comments about Including the Performance Expectation This Performance Expectation is addressed with some modifications because students work together to conduct an investigation around the effects of placing many different materials in the path of a beam of a flashlight. In order to fully address this Performance Expectations, teachers will need to incorporate student ideas into the planning and carrying out of the investigation.
This resource was not designed to build towards this science and engineering practice, but can be used to build towards it using the suggestions provided below.
Comments about Including the Science and Engineering Practice Students conduct an investigation when they work together to test which materials allow for the passage of light. In order to address this Practice more fully, the teacher may modify this lesson by allowing students to determine which materials to investigate. One possibility to begin this process would be to incorporate the items labeled “Second Grade”, as they would support students in developing capability around conducting investigations.
This resource is explicitly designed to build towards this disciplinary core idea.
Comments about Including the Disciplinary Core Idea Students figure out this Disciplinary Core Idea during the lesson when they carry out an investigation around which materials allow light to pass through them. To fully address this Disciplinary Core Idea, teachers may need to build in further discussion with students to develop these ideas.
This resource appears to be designed to build towards this crosscutting concept, though the resource developer has not explicitly stated so.
Comments about Including the Crosscutting Concept Cause and effect is addressed in this lesson as students test materials by attempting to shine the flashlight through them. In order to support students in designing simple tests to gather evidence to support or refute student ideas, it will be necessary for the teacher to involve the students in the planning of the investigation. Students might share their experience around the behavior of light, how it passes through, is blocked by, or reflected off of certain surfaces. Students can use this background knowledge to design a simple investigation and gather evidence to support or refute their ideas.
