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.

Ball Bearings in freefall

Creating a strobe image of two ball bearings falling. One falls vertically and the other is propelled sideways. The camera used a flash on a strobe setting capturing an image every 1/15 of a second.

 

All in a Heartbeat

 Taking an ECG on a student in A-Level Biology using the @pascocienctific ECG sensor. Using a digital stethoscope, the students could record and play back their heartbeat and tie this in with the ECG that they recorded.

Oxytocin in Psychology

 A-Level Psychology: Oxytocin, the "bonding hormone," is naturally released during sex, childbirth, and breastfeeding. As a synthesized drug, it's been explored as a potential treatment for various psychiatric disorders. #Psychology #Oxytocin

DBMS and GIS

 A-level Computing DBMS and GIS. Another real-world use for relational databases? Integrating them with GIS to pinpoint houses near a river, optimize delivery routes, or count homes in a school zone.
