This is our contribution to the Science Fair Carnival, dreamt up by Dawn and hosted by the infinitely resourceful Stef of The Eclectic Homeschooler. Our family has cheated just a bit, featuring pictures from a science class the children took last week at a local nature preserve. Theresa (11) will narrate from here:
We began by assembling our rockets from a tube, a piece of straw, a strip of metal, three wooden fins, two pieces of string (elastic and teflon), a small blue ring, a premade engine, a nose cone, a paper tab and a streamer. The tube is the body of the rocket; the straw and the metal attach the rocket to the launch pad; the fins help it balance as it flies; the elastic string keeps the nosecone from coming off the rocket; the teflon string keeps the elastic string from burning up; the ring keeps the engine in place; the paper tab keeps the strings in place; the nosecone cuts the air in front of the rocket; the streamer allows you to see where your rocket has landed; and engine provides fuel and force for the rocket. Without the engine, the rocket would not be able to fly.
The launchpad is attached to a remote control. When the button is pressed, the engine within the rocket is ignited, causing it to lift off the ground. Please click here for a video of one of our attempts.
We loved shooting our rockets in this beautiful setting . . .
and, of course, while we were out, we found yet another mantis! They seem to follow us wherever we go!
