In this lesson students collaborate while planning, constructing, and testing a structure that reduces the warming effect of sunlight on an ice cube. This is the seventh lesson of a nine lesson betterlesson.com unit by Joyce Baumann.
K-2-ETS1-3 Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs. Clarification Statement: none Assessment Boundary: none
This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation This lesson affords students the opportunity to work collaboratively to design and build models that will reduce the warming effect of sunlight on an ice cube. After the structures are built the students test their structures outside. As a class they analyze the results of each structure compared to each other and to the control ice cube. The designs of the student-built structures would be enhanced if students were provided with background information about materials and how sunlight affects them prior to completing this lesson. Completing the lesson as instructed fully meets this Performance Expectation.
K-PS3-2 Use tools and materials provided to design and build a structure that will reduce the warming effect of sunlight on an area. Clarification Statement: Examples of structures could include umbrellas, canopies, and tents that minimize the warming effect of the sun. Assessment Boundary: none
Comments about Including the Performance Expectation Students work collaboratively using tools to design a structures that will prevent an ice cube from melting. Students test their structures outside. The results of each structure are compared to the control ice cube and finally the results are analyzed. Students should develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem. Completing the lesson as instructed and adding the suggestion fully meets this Performance Expectation.
This resource is explicitly designed to build towards this science and engineering practice.
Comments about Including the Science and Engineering Practice This lesson affords students the opportunity to work collaboratively to design and build models that will reduce the warming effect of sunlight on an ice cube. After the structures are built, the students test their structures outside. As a class they analyze the results of each structure compared to each other and to the control ice cube. This allows the Practice to be met.
This resource was not designed to build towards this disciplinary core idea, but can be used to build towards it using the suggestions provided below.
Comments about Including the Disciplinary Core Idea This Disciplinary Core Idea is addressed indirectly in this lesson. The teacher will need to use questioning techniques to ensure that the students understand the ice cube is melting because of sunlight. The students are being asked to build a structure that will lessen the effect of sunlight on an ice cube.
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 fully address the Core Idea, the teacher should ensure that students use journals or develop a Student Activity Page to formally record the questioning, planning, creating and testing phases during the engineering process. Students could extend their learning by sharing their reasonings for building the structure that they built before they test it. After class evaluations, they should share how they would change the design to work better.
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 During the testing phase of this lesson students will begin to understand that an ice cube will melt if it is in the sun because the sunlight heats it. The shade structure will affect the speed at which the ice cube melts. Teachers can reinforce this Crosscutting Concept by helping students recognize and record this observation and by asking questions directly related to cause and effect relationship pattern.
