I would choose the topic of Space and Aliens. I have often veered from teaching about aliens but this module has shown how fun it can be done and how to leads to lots of questions.
I would start with a KWL to see what they know about aliens and Martians and what they would like to find out. Then I would read the story Martian Rock by Carol Diggory Shields.
I loved the Martian activity shared in the module. I would then pose the question what does a Martian look like. I would give the children some time to think, pair and share their ideas. I would select some children to come and draw on the whiteboard. This always assists this who struggle with idea generation.
The children will then all set off to predict what a Martian would look like to them. They would sketch their Martian. We would do a mini plenary here and share some of their sketches on the visualiser. We would discuss similarities and differences, talk about shapes and sizes of their Martians.
The children would then conduct the experiment by making their Martian out of plasticine using their sketches as a guide. When they have made their Martians they would then create a short animation using stop go motion. I used this a lot with my First Class Children last year and they loved it. So I believe it work very well with the Martians. Stop go motion makes it look as if the small plasticine models are moving by themselves. Ideally I would like to incorporate a space background and this could be made prior in a different lesson to be used in this.
Again at the end the stop go animations would be shared with the class or viewed in a silent walking tour.
