The materials and equipment you will have include 100% alcohol, test tubes (large diameter test tubes), fermentation tubes (smal
ler diameter tubes closed off at one end), yeast, and sugar. The yeast and sugar are mixed to start the fermentation process. The fermentation tube can be used to collect gases. State a testable hypothesis for your speculation from item 8 above, using the above equipment.
A hypothesis is a proposed statement explaining the relationship between two or more variable which can be verifiable through experiment. In this case a testable hypothesis would be.
When yeast and sugar are mixed together during formation, it will cause the sugar to undergo a high rate of glycolysis and CO will be present in the fermentation tube.
