This can lead into a study of the natural history of protozoans and algae, and finally into the exploration of bacteria and their viruses. The students encounter a series of developmentally appropriate experiments in which parameters may be varied. As the student advances these fundamental concepts are tested in teh laboratory for their veracity. The implications of these lessons and the research they span can then be discussed in depth and dealt within an interdisciplinary manner in the classroom. This botanical experience will be a platform upon which the students will over a period of years build a study of chloroplasts and other 'friendly' prokaryotic organisms.
Yeast makes bubbles in the dough.
Humans are only one of a very few who are tool users. Introduction to optical tools - the magnifying glass. The main tools will be balloons connected to bottles, which contain a fermenting yeast suspension. Various amounts of sugar will be added to each bottle and the volume of evolved gas will be estimated by the inflating balloons. A first look at chloroplasts.
