This week we finished the Jackson Middle School case. we concluded that the kids that were sick had salmonella. salmonella causes the same symptoms that the kids had. also the grams test turned red which meant it was negative. we wrote up our lab report and handed it in.
then the next day we took a toothpick and rubbed it ageists our cheek. we looked at it 4 different way under a microscope.

• way 1- dye high mag.
• way 2- dye low mag.
• way 3- water high mag
• way 4- water low mag

when you used the water it was much harder to see then with the dye that brought out the cells. for home work that night we looked up a diagram of the animal cell and plant cell. the next day we peeled a potato so that the slices were almost transparent. we did the same with grass. we looked at that 8 different ways.

• way 1-water high mag
• way 2- water low mag
• way 3- methylene blue high mag
• way 4- methylene blue low mag
• way 5- lugol (red dye) high mag
• way 6- lugol(red dye) low mag
• way 7- grass high mag
• way 8- grass low mag

the next day (Friday) we checked over our homework and discussed it. once we discussed both cells we made a chart with structures and what they do.

cytoplasm- holds everything together

nucleus-controls everything that goes on in the cell

cell wall- protection, structure

mitochondria- needs more research

cell membrane- contains the organelles of the cell and controls what passes in and out of the cell

nucleus membrane- protects the nucleus

that is basically all we did this week
