Air Pressure in a Balloon

 What is the air pressure inside a balloon? The students were amazed at the answer using a @pascoscientific wireless pressure sensor and Capstone to prove the pressure didn't really change. #teachphysics #STEM #Science

The power of air pressure

 The power of a little air pressure. A few pumps was enough to lift this full 15kg Cannister of Butane by a few centimetres.

Investigating Photosynthesis

 Investigating Photosynthesis and the distance of the light source and the inverse square law. I find you have to get the light very close to get bubbles that you can measure.

Making own resistor sets

 Making up our own resistors using Locktronics by @MatrixTSL Predicting The total resistance and then measuring it to see if correct using Ohms Law. #iteachphysics #STEM

Simple Distillation

 Doing a distillation in organic chemistry to separate the products. Explaining why the water has to go up the condenser - seemed so strange to the students.

Specific Heat Capacity

 Using @pascoscientific Capstone to look at specific heat capacities Graphs showed the different uptakes of of the heat in the same time, which gave a better idea of this concept of specific heat capacity. #iteachphysics @chatphysics #STEM

Practical uses of a thermistor

 #Physics Investigating the properties of a thermistor using Locktronics by @MatrixTSL and then having to turn this into a make shift digital thermometer using some coding on a Raspberry Pi and some Python. #iteachphysics #Science #STEM
