5 Points =
The student completes the task independently. He/she identifies and
compares the physical and chemical properties of the various brands of the
chosen product. The student develops a classification scheme for the chosen
product and classifies the various brands using this scheme. He/she
develops a hard copy of the results, demonstrating an understanding of
classification systems. The student's oral presentation to the class is
precise, clear, and fluently delivered.
4 Points = The student needs minimal assistance to
complete the task. He/she identifies and compares most of the physical and
chemical properties of the various brands of the chosen product. The
student has some difficulty developing a classification scheme for the chosen
product, but develops a hard copy of this scheme. The student demonstrates a fairly good understanding
of classification systems. The oral presentation is fairly precise, but the student has some
difficulty with delivery.
3 Points = The student needs considerable
assistance to complete the task. He/she identifies and compares only a few
of the physical and chemical properties of the various brands of the chosen
product. The student makes a limited classification scheme based on a few
of the physical and/or chemical properties and demonstrates a limited
understanding of classification systems. The student's oral presentation
lacks clarity, is not well organized, and is not very interesting.
2 Points = The student needs constant assistance to
complete the task. He/she identifies and compares only one or two of the
physical and chemical properties of the various brands of the chosen
product. The student, therefore, is unable to make a meaningful classification
scheme based on the properties of the project and demonstrates little understanding of classification
systems. The student's oral presentation is vague, poorly organized, and poorly presented.
1 Point = Even with assistance, the student is unable to complete the
task. He/she is unable to identify physical and chemical properties of the
various brands of the chosen product. The student is unable to produce and present a hard copy of the classification scheme and displays
no understanding of developing a classification system. The student's oral presentation to the
class, if made, is meaningless.
0 Points = No attempt is made to complete the task.
