A concept cartoon is an innovative way of eliciting discussions about science concepts. For example, it can present differing views on a scientific phenomenon from different characters.
I am not an artist but do wish sometimes that I could make classroom discussions more interesting by using relevant cartoons or comic strips. Then I stumbled upon some websites that enable you to create your own comic strips using readily drawn characters and images. The characters have a number of common facial expressions, which makes the story-telling fun. You may even add on your own colours or drawings such as backgrounds and other objects later on after you have downloaded the soft copy of the image for the strip that you have made.
Do try out http://www.makebeliefscomix.com/Comix/ where I made a strip as a trial. I certainly hope to get more ideas for teaching in future where this will come in handy.
