Yatin Sir, you posts are very informative and easy to use in classroom scenario. the way you have shown the usage of moovly as a tool in visualization of a concept is great. This tool can be a power booster for science teachers and as well as language and art teachers for building STEAM attributes in a child.
Please keep sharing .....
