Balancing & Weighing
	Assessment Suggestions

HASP is in the process of learning about assessment. The assessment tools found here are suggestions and perhaps beginnings for your own assessment ideas. Since we are in the revision process, if you choose to use these assignments with your students, please send us your results via e-mail, hasp@dcs.edu.

Purpose:

To determine the student's ability to use equal arm balance to help them place the 6 items in serial order from lightest to heaviest.

 

Objective:

Students will demonstrate competence in comparing by weight.

 

Materials:

See materials list Lesson 13 (teacher supplies cans) in the Balancing and Weighing Teacher's Guide.

 

Task:

Follow the lesson plan for "science" extension page 121. Students will predict where the objects will fall in the sequence according to their weight and order all objects from lightest to heaviest. Students will use the equal arm balance to test their prediction and reorder the objects, if necessary.

 

Criteria:

Students will be assessed on their ability to use the equal arm balance to determine the relative weight of the six given objects.

 

Students will be assessed by observation of students' performance and teacher interviews (as noted in the anecdotal record of observations).

 

Rubric:

3	Excellent. The student uses the equal arm balance but must go through the process of testing each new object with all sequenced objects in order to determine the sequence. The sequence determined is correct.
2	Adequate. Each object is compared on the equal arm balance and the process is logical but the resulting sequence is incorrect.
1	Inadequate. Objects are compared on the equal arm balance, but the process is not logical or student does not use the equal arm balance.
0	Did not try
