Investigaing a CRT.

 I grew up with CRT's, but for most of the students they have not seen one, so I took off the case from the Oscilloscope to show all the parts and how it works.

Ionic Shapes

 We used a Brother Scan'n'Cut machine to cut out 1+, 2+ and 3+  ions along with the 2- and 1- counterparts. The students seem to find it easier to create and write down chemical formulae.

Breathing Model

 I had some problems breathing then I realised there was a hole in my diaphragm, so after a few minutes the rubber was replaced and I could breath again. Fortunately this was the model not me.

Smartcart with adjustable fan

The @pascoscientific smart cart with the fan is great for some experiments, but using the template on the site, you can 3D print a base for the fan which allows the fan to be turned in all sort of angles which is even more useful especially for resolution of vectors.

Momentum

The @pascoscientific Smart carts excel at momentum equations. Even with quickly done student data the students can determine the relationships between mass and velocity in collisions

Getting into Coding

I find writing questions is hard. It is easier to start with the answer and find numbers that work rather than designing a question. Here coding comes in generating  lots of different quadratic equations at different levels. Work in progress.

Numbers of batteries and strength of magmetic field
