A teacher of Class VII demonstrates the following activity in the class: “A leaf is put in a test tube and spirit is poured over it. Then the test tube is put in a beaker half-filled with water and heated till the leaf is discoloured. The leaf is then taken out and a few drops of iodine are put on it. The leaf turns blue-black in colour.” After this activity, the teacher gives some questions for the assessment of various indicators of learning. Which of the following would assess ‘analysis’?

Correct Answer Can this test be done without removing chlorophyll?

Co-curricular activities in Science class are usually organized outside the classroom to provide opportunities for students to develop their special talents and to creatively express themselves through various forms.

If a teacher of class VII demonstrates the following activity in the class.
A leaf is put in a test tube and spirit is poured over it then the test tube is put in a beaker half-filled with water and heated till the leaf is discolored. The leaf is then taken out and a few drops of iodine are put on it.
The leaf turns blue-black in colour.
Can this test be done without removing chlorophyll?
This statement would access "analysis".

  • To answer this question, analysis has to be done, that is, the results obtained by removing chlorophyll and experimenting depends on the analysis itself.
  • The method in which to solve a problem is to divide that problem into pieces and to analyze the expressions of the assembled object separately and test them.
  • The analysis method is a research method that moves from "complex to simple", "unknown to known" and "inference to inference".
  • In the analysis method, students develop a habit of deciding the reasoning power correctly.

Hence, from the given activity the assess ‘analysis’ is, Can this test be done without removing chlorophyll?
