TRS-80 Model 100

 The TRS-80 Model 100 coming out for its annual outing, showing to the students a working laptop computer from 40 years ago.

Chemistry visualising problems

 Stereochemistry is very difficult to visualise, even sometimes when playing with models.  Even looking at this, some students couldn't really fathom out handedness and needed to play with the models until they could rationalise their thoughts.

Electricity Revision

 The challenge: Revise all the electricity Topic in 1 hour and carry out 3 required practicals. Easy with the @pascoscientific voltage/current sensor and Capstone, printing out perfect graphs of the results for all the students. All the Demos were done by students. Even I was surprised at the speed we covered all the experiments.

Lascells Cloud Chamber

This is what a cloud chamber should be like. This is the Lascells Cloud Chamber. It is set up in minutes, and after 5 or so minutes, trails from the supplied Thorium welding Rod can be seen, and the students can see the radiation.

 

Centripetal Motion

 Demonstrating that a ball does indeed travel in a straight line when released from the centripetal force The ball travels around the loop until the loop is lifted then it carries on in a straight line. The loop was made from a hoop with insulating foam around it.

Milk decay Experiment

 The milk decay experiment. Most of the students I talked to had no idea what this experiment showed - many had not done it because of a lack of time or resources. It is such an easy experiment to do and get good results.

Exam Diary

 Some of the Students are prepared and ready for this. A few are thinking about starting to revise soon, but most are in between desperately trying to learn all sorts of things and identifying new patterns.
