CBSE Board Exams 2022: Class 9, 10 students need not come to school for lab work

On October 29, CBSE in its latest circular issued a list of video and guidance material for 75 experiments the students are required to do in Classes 9 and 10.

CBSE Board Exams 2022: Students enrolled under the Central Board of Secondary Education (CBSE) in Class 9 or 10 need not come to school to perform hands-on science assignments such as sublimation, filtration or evaporation. On October 29, CBSE in its latest circular issued a list of video and guidance material for 75 experiments the students are required to do in Classes 9 and 10. “Further to this (experiment through OLab), the CBSE has curated a set of alternate experiments using simple, readily available household materials that learners can use to do these activities at their homes,” the circular said.

“The hands-on activities have been designed to have similar learning outcomes for all the lab experiments required to be done in (the academic year) 21-22 for class 9 and 10.” Students can perform these experiments along with many other practical tasks, at home using easily available tools and materials and with the help of instruction videos and written guidance texts uploaded by the CBSE. For sublimation, filtration and evaporation, for instance, all they need are stuff such as plastic bottles, insulation tape, cotton, rulers, teaspoons, common salt, sand, and ice cream sticks.

The move has been welcomed by academics, which comes at a time schools have reopened for Class 9 upwards in most states. As the classes are not mandatory, schools are facing attendance has been low because of parents’ Covid jitters. Last year, as the schools were closed because of the pandemic outbreak, the CBSE allowed students of Classes 9 to 12 to perform lab experiments virtually on the online platform OLab. The students issued instructions step by step while a computer carried out the experiments as directed, a science teacher from a Navodaya school explained. Students can then record their observations in writing after performing the experiment.

As the material prescribed to perform the experiment are deemed to be safe for the children to do on their own, schoolteachers are required to review the experiments and materials before assigning tasks and advise parents whether supervision is necessary for any particular activity, the circular said.
