Lego Mania 3: Going, Going, Gone!

Now mathspigs, let’s get mobile.  There is a lot of symmetry and 3D rotations involved in building a Lego ca. You can go low -tech or high tech. Get ready mathspigs here we go:

1. Lego Balloon Car

 I don’t think you’ll need instructions for this one. Maybe you could pimp that ride, mathspigs.

……………………………………………………………………

2. Lego Rubber Band Car

You will find instructions @ eHow     

……………………………………………………………………

3. Cool Lego VW

Ramping up the challenge, how about building a Lego street car.

If you have a Lego Car Kit you can make a really cool VW and a cool video clip as well:

4. Lego Street View Car 

If you are the ultimate geek then this is the Lego car project for you. It could take years, mathspigs, but worth the sweat.

5. Lego Bike

Or just get on your Lego bike.

Lego Olympics Closing Ceremony

The closing ceremony is chaos. All the athletes crowd together.

There is one last lot of calculations, mathspigs.

Think about this.

% Gold Medal Winners:

At the 2012 London Olympics there will be 47 Gold medals awarded in athletics.

There will be 2,000 athletes competing for these medals. Now some athletes will win more than one Gold medal and some events eg. the relay race involve more than one athlete. Each member of the winning relay team wins a Gold Medal.

Approximately what % of athletes won’t win a Gold Medal at the London Olympics?

Ans:  97.65%

Probability of Winning a Gold Medal:

Ha-HA! Tricked ya! Such a calculation would be meaningless.

The core to all probability is, or should be, RANDOM SELECTION.

Lottery balls fall randomly into the tube. But the Olympic athletes represent a BIASED SAMPLE. Athletes are selected for the games. They must qualify for an event. They train. The chance of one athlete winning is quite different from that of another.

…………………………………………………………………

Eight numbered  100m-sprint athletes is a Biased Sample.

………………………………………………………………

Eight numbered lottery balls in last nights draw make up a random sample.

This brings us to the end of the Lego Olympics.

We will finish with this end song by Lego Rock Band and some Lego fireworks.
