Objective - Can I make rockets successfully launch and say why some are better than others?
Make air-propelled rockets.
Launch them into ‘outer-space'.
Decide which sheet material e.g.tissue paper, newspaper, printing paper, card, acetate sheet & tin foil to use for the rockets.
Use scientific vocabulary related to the properties of the materials to explain their choices (thick, thin, bendy, stiff, heavy, light, heavier, lighter...)
Ask & answer questions about how the rockets are powered & what makes them move (How...? What do you think...? Why do you think...? What if...? Is it a fair test? What can you do to...? Does it make a difference if...?)
Method 2: Instead of a straw, use a toy rocket launcher, if you already have one, or a launcher which can fit on an empty drinks bottles/foot pump.
The rockets are made by rolling paper or other materials loosely around the launcher, to make a tube, before sealing 1 end with sticky tape to make nose cones. Launch the rockets by sliding them onto the launcher & squeezing the bottle firmly & rapidly.
