A circuit is a Hula-Hoop.

Here's a video from Pasir Ridge International School of Theresa Marriott's 3rd and 4th graders writing about electricity.

This is from our definition poem exercise where students (working in pairs)  first list attributes about their vocabulary word - what the word can and can't - would or wouldn't do. They then select from their pre-write items to prioritize the information they will presenting their first draft which is then immediately revised.

Gather information - prioritize - visualize - then revise - nifty little format providing deep thinking and then quick assessment if I say so myself.

This was one of the younger bunch of pupils we have run this clinic with and we think they did us proud.
