Foldscopes on the go! A follow-up workshop for TSWREIS teachers

Following our earlier two day workshop in June, teachers in 10 residential schools of three districts of Telangana introduced foldscopes into their Grade 8 and 9 classrooms. We kept in touch with them, some long-distance and the nearby ones in weekend visits. There were a few unexpected starting hiccups, that we shared in the last…

Zooplankton in a water puddle
