Vacuum

I can't understand why I can't pull these apart. There is nothing in there holding them together.

Electrical Conductivity

This is not usually the first sensor I think of to use but for many physical and chemical reactions the @pascoscientific electrical conductivity probe provides an insight into the composition of the solution. #STEM #Science

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.
