bacteria!

Last week for science we went to Rigby Lake and gathered four jars with lake water in each one. In each jar we placed a different type of food for the bacteria: eggs, rice, soil, and hay. After that we placed the jars into a cooler in brother Butikofer’s shop. We left them there for a week. this week we were learning about prokaryotic cells (cells that have no distinct membrane bounded organelles). Don't worry if you don't know what it means. Few do. We also learned abot pathogens,oranisims that cause disease, Saprophytes, organisims that feed on dead matter, parasites, organisims that feed on a living host, aerobic organisims, organisims that require oxygen, and anerobic organisims, ones that don't, how bacteria reproduce, exponential growth, logistic growth,plasmids, transfomation,transduction, endospores, gram positive and gram negitive bacteria, and so on and so forth and ect.

Now... To grow, bacteria must have the following things: moisture, moderate temperature, nutrition, darkness, and the proper amount of oxygen. We, the considerate people that we are, provided them with all of those things. The greatful bacteria began to thrive and grow in prosperity and peace. When we removed them in a week, they had multiplied to staggering numbers. We placed a drop of water out of each jar onto a glass slide. The bacteria we had chosen were greatful and decided to show off the best that they could. We were satisfied and impressed with the fruits of our labor. We saw coccus bacteria, bacillus, spirillum, diatoms, volvox, amoeba, and more. It was super exciting and fun. We can’t wait to do more Biology!
