Our history of flight unit has been so incredibly fun! I am continually impressed with our little book and the practical, relevant projects that come out of it. It was well worth the $11 I paid for it. I’d have paid three-times that and still considered it a good deal.
Today the kids and I made dirigibles; also known as blimps. Which, in case you were wondering, are different from hot air balloons because they have power and can be steered. :) The design for these was really basic. Three squares of egg carton plus two helium balloons, plus tape. Done and done. And then the fun began.
My kids spent literally hours sticking things like pennies, ping-pong balls, and little action figures in the gondola to see how much weight the balloons could hold without sinking. And to see which items made the balloons sink the fastest, and so on and so forth.
At one point Linc had his weighted just so; it sank very, very slowly to the ground. But he discovered that it would stay afloat if he blew on it, and that he could steer it all around the family room, landing and taking off again whenever he pleased. So cool!
Ivan and Adelia also had fun with this project. We’ve got The Ivan-Berg and Del’s Zeppelin.
