Hi, I have a formal observation on friday abd it's a big observation so I really want to do well. I've been told that I will be doing a practical science lesson based on exploring how objects that can be stretched, twisted, bent or squashed. I have not yet been able to observe a practical science lesson so I am extremely nervous and have no idea what to do. It is a year 2 class and i will not have a TA to help with differentiation and LAs of the class do need a lot of support. I have been told to have clear differentiation and to include mini plenaries .... I feel so lost! The only thing I can think to start the lesson is to do class predictions about different objects (yet to be decided on). Any help would be greatly appreciated! Thank you in advanced.
