Information on how easy it is to do each experiment – available for each experimental video. Based on 4 categories recommended by Cambodian teachers – (1) Resources, (2) Time to set up, (3) Time to implement and (4) Difficulty

 

Resources:

Everyday/Everyday and Specialist/Mainly Specialist

(Everyday meaning things that could be expected to be accessible in rural areas, from the market etc. / Specialist would mean *any* item that would be purchased specifically for science - e.g. a test tube, tongs)

• Collecting equipment – some notes on what might be needed to be collected from outside of school labs

 

Time to set up:

• Preparing chemicals

• Putting out equipment

 

Time to implement:

• This is written as an estimate of time to do the experiment on the video/sheet

 

Difficulty:

very easy / easy / medium / hard / very hard    

Examples

• very easy = melting ice

• easy = use of indicator paper for testing acids/bases

• medium = creating an element - chlorine (it's a bit fiddly, it needs to be tested beforehand, teacher needs to know the expected result clearly)

• hard = calculation of heat quantities (Q = mCdeltaT)  

• very hard = fractional distillation
