    Calculation Achievements(3)
    -Describe an aspect of the event using arithmetic.: Our egg was 56.1 grams and our protection was 25 grams making the total weight 81.1 grams.
    -Describe an aspect of the event using geometry.
    -Describe an aspect of the event using algebra.
    Given that the bullseye was 25pi square inches and that the circular target was 552.25pi square inches the bullseye makes up 4.52% of the target.




    Mark I, sketchy original design
     Its now or never...

     It failed. But hey, fail earlier fail often!

     New design, SPONGES. They really added a lot to the protection, nothing to the weight. Wrapped in foil to keep it all contained.
     :) 25 grams. Light as a feather
    No design is complete without a little propoganda. Were getting yolked, youre getting scrambled.

    Khan Academy

    Mr. Lemei is a great teacher and when writing this I am not bagging on his teaching skills in any way. I had some difficulty understanding permutations when Mr. Lemei explained them and Khan's video ended up really enforcing my knowedge in the subject. I am going to use khan video's whenever I am having trouble with a subject in math!
