kinds of materials tested to ..? see which is best to keep hot drinks hot and cold drinks cold? I need to locate images and in particular educational videos to show to children in my class how to conduct an experiment to find out the best types of materials to maintain the temperature of the drink whether it be hot or cold. I’ve tried youtube but have come across stuff on pre-made and bought thermos flasks/jugs which isn’t what I have in mind. Any help would be appreciated.
