This online resource provides a way of demonstrating photosynthesis in action.
The procedure used for this investigation was produced by the ARC Centre of Excellence for Translational Photosynthesis.
It is well illustrated and uses leaf disks suspended in water to demonstrate the production of oxygen during photosynthesis.

Standard Operating Procedure (SOP) and detailed method including photographs for how to perform a lung dissection. The accompanying example risk assessment should be used as a guide only, and users should consider risks and safety measures in their local environment before proceeding.
The external link below to the STEM Learning website is a very good instructional video for teachers/demonstrators.
This online resource looks at natural selection.
The resource is a lesson plan for a practical activity or demonstration that also provides detailed teaching notes and a student worksheet.

This resource looks at the concepts of collisions and momentum.
The online resource is an entertaining student presentation including slides, two videos and a short experiment that focuses on the physics concepts of collisions and the role of crumple zones.
The video shows the equations involved with momentum and impulse to reduce force through crumple zones. Also a short experiment of a collision between a car and a wall, with and without a crumple zone, is shown and the difference in force is calculated and explained.
