Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube‚ shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting‚ because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its touching but it shouldn’t matter because it will be touching air and glass which both

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

The Bobo Experiment was performed in 1961 by Albert Bandura to try and prove that people‚ especially children‚ learn their social skills and behaviors from copying or mimicking adults in their lives rather than through heredity genes.

These issues have been present for many years‚ even before the media used these
