BTSSS has a well-equipped Science Laboratory for imparting practical knowledge in Physics, Chemistry and Biology for classes IX, X, XI and XII and the same laboratory is used for imparting practical knowledge in General Science for other classes VI, VII and VIII as well. The aim of having the lab is to provide proper adequate equipment and ample time for every student to perform the experiments as per the CBSE guidelines.

​

The laboratory is well-stocked with sufficient burettes, tongs, tweezers, forceps, test tubes, conical flasks, laboratory balance, specimens, slides, microscopes, many chemicals and useful instruments so that every student gets the opportunity to carry out the experiments individually. Well-qualified and experienced teachers guide the students to explore the world of science through a meticulously planned schedule of practical classes. In addition to this, the safety of every child while handling the chemicals and instruments is duly taken care off.
