MYP3 Mathematicians Helping Others Understand Curves

Before I introduce three fabulous websites, I'd like to say that ALL of the MYP3 mathematicians have produced wonderful work demonstrating their understanding of curves and their transformations. Mathsland is proud to call them all citizens.

In our unit we were focusing on linear functions y=mx+p, and dipping into some quadratics but some decided they would like to go further and investigate other curves.

We had linear, quadratic, square root, Archimedes Spiral, sinusoidal and exponential curves. It was busy in Mathsland because everyone had different questions and a different adventure.

Three students, Annalis, Chanya and Eugene (alphabetical order chosen there), created websites using skills taught to them by the much beloved and missed Ajarn Marcus. By creating websites they are providing a service to other learners in the world of mathematics that want to know about sinusoidal waves and exponential functions.

Students used the desmos.com/calculator and its groovy sliders to play around with parameters to spot patterns.

Now for the websites:

Annalis' Exponentials are Cool

Eugene's Vas Are Sinusoidal Waves

Chanya's Parabolas

The Weather and its Patterns can be COOL

A 3-D animated image of Reanalysis-2 data for the first ten days of July 1979, in six-hourly intervals. This animation shows a constant 100mph wind speed surface in red. (Note the stronger, more widespread, polar jet stream in the southern hemisphere--this is July, during the southern winter.) A cyan-colored, constant temperature sheet of zero degrees Celsius ripples across the globe, showing the freezing level. Near-surface wind flow is denoted by white flowlines. This image was generated with plots from Unidata's Integrated Data Viewer (IDV) combined with ImageMagick.

A plot of global, monthly mean wind speeds and directions for September 1990. These data are from the Blended Sea Winds dataset, available through NOMADS. This image was produced with NASA’s Panoply visualization tool.

Solar Power, Hexagons and a Moose

There has been a video of a moose lighting up a road as it crosses doing the rounds of social media recently. Today I clicked on it  and I was very impressed.  Two plucky people have invented amazing technology - solar panels that can be used as roads, pathways, outdoor areas shaped like hexagons.

If you are in MYP2 or you're a bee you know that the hexagon is part of making this technology strong.

It has won awards - check it out at indiegogo.com and in the video of one of their fans below.
Why isn't their government getting behind something like this? Great question.

I got behind it.
