Circulation

Connecting a model heart with tubes simulating the parts of the body the tubes go to and return from and then making the heart beat to observe how the blood flows. Using lots of air in the system helps see the blood flow more easily.
 

Win for Team GB in Australia

 A great weekend of watching the SailGP in Australia and a great win for Team GB

Inventory Metrics

 Learning all about inventory turnover metrics: turnover, carriage costs, order fill rate, average days to sell an inventory, the item fill rate, the cycle time and the return on the investment. And someone said this was trivial!

Preparing the computers

 ​Prep work: Loading the Raspberry Pi's with a new copy of Linux, Apache, PHP, MariaDB, docker, and Phpmyadmin so we are ready to create websites and do all things server.

Bond Angles

 ​I just taught an online lesson on bond angles across a period.  We explored how molecular shapes maximize distances between groups, why some molecules are bent instead of linear, and how trigonal bipyramidal structures have different bond angles. Fascinating stuff! #Chemistry

Electrical experiments

 Just 10 minutes to recap the three electrical components ( resistor, bulb and diode) used to make the voltage vs. current graphs. Just as quick as drawing them using the @pascoscientific voltage current sensor and Capstone and three circuits made and experiments done in 10 minutes.

A bit Dicey

 

Probability took a turn for the worse when the students had to work out the probability of throwing a number on different dice. They discovered that investigation was needed rather than making assumptions.
