[Activity] Angry Birds (part 2)

A quick elaboration on angry birds...

My last post about angry birds was lacking a bit.  I was severely jetlagged (still a bit now, but definitely better), and my memory was failing me.


Here are some of the other things we did with the following picture












*note* the following are all consolidation from the different groups that came up with different methods.

We talked about how we would find the vertex and the equation of the path so we can predict whether it will hit the pig (predicting act 3).

We threw a graph on the picture right on the smart notebook file.

We talked about what units we should use and we decided on "red bird."  in other words, the height of the red bird was 1 unit, and the width of the red bird was 1 unit.  (so we were counting by birds which was interesting, and the whole unit concept was fantastic to talk about)

We talked about what we would need in order to obtain an equation that would help us predict the result.

We talked about where the "x-axis" should be.  The common decision was to use the black part of the slingshot as a straight line for the x-axis.  We then threw a straight line there so we can see the x-axis.

We then established 0 (at the slingshot), and used the cloning tool to make many little red birds to help us measure our "red bird" unit.

I had another picture that showed the path until mid air, so we took that into account and measured the vertex.

then came crunch time and we sorted through some math

Finally arriving at the equation which hits the middle of the wood plank that the pig was leaning towards.

It was fun!
