We use them in genetics. Either you can taste it or not. Sometimes we send a strip home so the students can test their parents or siblings. It tastes revolting and I buy it from Southern Biol I think. P.S. Can be very funny watching this prac.
Better still... I know that I am a non-taster so I will taste a bit and get nothing and then pass onto other people. The look on their faces when they taste the PTC after seeing me not having a reaction... priceless
I was asked by a new teacher to get some PTC paper for the genetics topic in yr 10. I didn't check RiskAssess before I bought some from a supplier who made no mention of the fact that they contain poison and are not recommended to be used in schools. Is anyone else still using these strips??
We're doing the taste testing tomorrow. Does anyone know what the Potassium Iodine starch test papers are for in relation to the tasting? I can't find any info on it specifically for taste.
