I really enjoyed all the activities in this module. I have done rockets before with third and fourth class but wasn’t sure how to approach the topic in junior classes. The milk bottle mouse is perfect. It’s effective and encourages lots of questions and investigating. If I apply more force will the mouse go further? If the bottle is bigger will the mouse go further? How far do you think the mouse will travel? put a cone on the ground for your prediction. Does the material the container is made of make a difference? Can we add anything to the mouse to make it travel further? So often in science the make and do part can take up so much time that there is not much time for questioning and reflecting. This activity allows for the children to extend their learning in lots of different ways. Depending on how well they tackle this activity we can try the rocket with the vitamin tablet and container as a whole class or in groups.
