(Cambodian Secondary Science Experiment Videos)
The purpose of this website is to encourage Cambodian secondary Science teachers to use practical experimentation with students whenever possible. Videos are highlighted showing experiments from the Cambodian secondary curriculum textbooks and VSO experiment book. The experiments use materials that are available in Cambodia and can be done using easily purchasable equipment or recycled materials.
This site is an ongoing work in progress as more videos are added on a regular basis. Please contact us if you have a specific lesson that you would like to see a video on and we will see if it is feasible to create one and upload it.
