Air Pollution Topic

Biology Air Pollution Topic Practical Measuring the Air Pollution levels using the @Pocketlab Air recording the levels of particulates in different sites gives a series of horror stories relating to the air we breathe.

Punched Card

 Students ask me what sort of computer I used when I was at school. I didn't because only when I went to University did they have one, and then it was run-off punched cards learning Fortran, Algol 68 and Coral 66, and the computer took up the top floor of the Uni.

The Nature of Light

Red and Green Make Yellow. In years 10-11 this is the first time many students have mixed light and become aware of how light is different to paint. And that the sun produces white light broken into a spectrum rather than a yellow sun they got taught in primary school.

 

Balancing ionic Equations using Ionic cards

Balancing ionic Equations using Ionic cards. Using the Visualiser on the desk to take images and place them into the electronic book to record the results.

 

Simple Harmonic Motion

 A spring and a mass using @pascoscientific ultrasonic motion sensor is an excellent introduction to Simple Harmonic Motion. Within seconds, we had Position, Velocity and Acceleration graphs to compare the motion of the spring, and then, including a force meter, we could capture all the info.

Matrix Manipulation made easy

Matrices aren't hard but they certainly are laborious. The @CasioMaths CG-50 calculator makes Matrices very easy to manipulate so the student can get on with the important thing of learning how to solve problems using Matrices.

Lasers online

 Teaching all about reflection and refraction online. In the lab, we can work in a darkened room with a light source, Online, we have to use the laser in a Wave Tank using Fluorescein dye to help the green laser show up so the students can see the path of the beam of light.
