How to use the bottle to explain the theory of probability Bashny.Net

A few months ago the entire Internet was trying to repeat the trick with a bottle, the essence of which is simple: you need to throw a bottle of water so that in the fall she stood up straight.

Here it is:







Teacher middle school Lauren Hinton at first very annoyed by these experiments. The children were noisy, scattered everywhere plastic, shed water. But suddenly Lauren was struck with the realization that if you add mathematics and to turn the lesson into a complete entertainment? The trick with the bottle is perfect to explain to children the theory of probability.

So now her lessons look like this:







Children linger at recess, draw the graphs on the way home Lauren and I send emails on the weekends, trying to unravel the secret of the trick with the bottle. Liked the idea with other teachers who joined the solution.

As usual helps to understand complex math?

For an explanation of the theory Lauren offers guys experiment. Tossing the bottle, students calculate the probability of its landing, comparing numbers of indicators in practice determine the formula for a perfect flip and find out what is the probability of a successful landing, depending on other factors.

Here is how now look like normal math problem:

What is the probability of a successful landing of the bottle, if you have 4?

Does the amount of water in the bottle on the likelihood of its successful "landing"?

What is the role of the bottle design when calculating the likelihood of a successful landing?

Want poraskinut brains? Take a bottle of water, experiment and share your insights in the comments to compare with results of others. And remember: just here two identical answers may not be, but 2 + 2 does not always equal 4.
