Gliding Egg Landers.

In French class, a couple of weeks ago, we had read about people who go hang gliding for recreational purposes. When Mr. Chung mentioned making an egg glide, my mind immediately backtracked to that class. When I pitched the idea to Cindy and Stephen, we had all agreed that for the time being, it seemed like the best idea.

Given that each group only gets 25 straws, a sheet of newspaper and a limited amount of tape, we'd have to build a structure that wouldn't be too big, but one that would be able to keep our egg from cracking. A hang glider model would be perfect for this assignment because it does not require a complex structure, nor an engine.

We could build a tringular shaped 'wing' which would provide us with the gliding element, and provide a structure we could attatch our egg from.

Taking into consideration that a chicken egg is hefty in weight, in comparison to the straws, that will most likely be a problem we'll have to work through as a group.

Till Wednesday, gliding egg lander.

Velocity and Time Lab Activity.

On March 8, 2011, we did our first lab activity in class. The lab involved velocity/time, and distance/time graphs which we had to try and match through a motion detector. The first graphs we tried were distance/time graphs and after a couple of tries, our graphs started look like the graphs given. For a positive slope, we walked away from the motion detector, and for a negative slope, we simply walked towards the detector or simply stayed in the same spot for the horizontal lines. After conquering graphs B and C, we came to graph D which was our first graph for velocity/time. The velocity/time graphs, which is pertaining to speed, were a lot harder to match. They required geisha-like steps at a certain speed, closer or farther away from the motion detector and without a doubt, there were many trial and errors. This being said, the velocity/time graphs were a lot harder to try and correspond with.

Who can walk like a geisha at a constant speed for so long?
