Spring Is In The Air...

Spring is back... bring with it the scent of new flowers, freshly cut grass, and ...rocket fuel??

Yep, after the all-important Gateways we'll be able to get out and experience a little applied Math and Physics... using Trigonometry to find the heights of the flag pole and stadium lights... and also calculating the heights of our model rocket launches.

Here are some clips from last year...

Gateway Algebra (04/01/2010) Contextual Problems - Solving Equations with Variables on Both Sides

Students will work contextual problems involving Algebra and some Geometry.

The equations used will involve solving with variables on both sides.

Algebra I (3/31/10) Experimental Probablility

Experimental Probability (also called Relative Frequency) is discussed.

The Theoretical Probability of a coin toss is as follows:

P(H) = P(T) = 1/2 = 0.5 = 50%

Using different denominations of coins, small groups will conduct 100 trials of coin tosses, tabulate the results, and write up the results and conclusions.

Results from each class will be posted at the end of the day.

A host of Probability information and videos can be found below:

http://www.onlinemathlearning.com/math-probability.html



Groups:

%H %T
50 50 Because we flipped coin so wildly
46 54 We didn't throw it the same each time
50 50 True random flipping
60 40
44 56
49 51 good flipping
60 40 one side must be heavier than the other
50 50 the more flips you do the closer to the theoretical we get
44 56 could have flipped coin more randomly

Average: P(H) = 453/9 = 50.333 P(T) = 445/9 = 49.667
