In this lesson students work with various materials to design a device to best melt an ice cube.
For this lesson various resources are needed including:
I begin the lesson by giving students an overview of what we will be doing in the lab.
This First Video shows me reviewing the lab with students in terms of the objective and procedure for building their device.
This Second Video shows me explaining to students how they will be analyzing their data and then recording on the class graph.
During this section of the lesson students are performing the lab.
After students turn in their labs I grade them using the rubric on the second page of the lab paper.
Here are some examples of students' graded labs.
In the first example Melting Device Student Example #1 the student shows that he understands how heat capacity plays a role in melting ice.
In the second example Melting Device Student Example #2 the student also shows that she understands how heat capacity plays a role in melting ice. She also does a great job with drawing and describing her device.
In the third example Melting Device Student Example #3- the student mixed up heat capacity with the understanding that high heat capacity materials such as wood and wax would make things melt which is the opposite of what I was trying to teach.
In the fourth example Melting Device Student Example #4 the student also demonstrates mastery of what it takes to help the ice melt versus keep it frozen.
