I intend on doing this activity in pairs with 1st and 2nd class. I would begin my lesson with a video of Space X taking off. After some discussions and wonderings. I would then proceed to the Rocket Mice activity. I would present the class with a ‘mouse’ – constructed using the template provided. I will explain the children that will create and design their own mice in pairs and will investigate ‘How high/far can you make your Rocket Mice fly?’. Some pairs will be asked to consider ‘How could you make your rocket mouse go more slowly?’; ‘Can you make your rocket spin as it falls?’. We will then make the connections, for instance squeezing shampoo or ketchup bottles and the resulting air pressure forcing the liquid out. I love the creativity and simplicity of this activity and can imagine it would bring great energy and excitement to a class as the endeavour to tweak (alter a variable) to bring about particular changes to the outcome.
