afternoon delight!
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!
