This week, we wrapped up our chapter on cells and microscopes and took our second test of the year. In our next chapter, we will focus on the processes that allow cells to obtain resources, produce energy, and reproduce. We did a "Carrot Osmosis Lab" which showed students what happens to baby carrots when placed in fresh water and salt water solutions. We were able to explain our lab results by recalling the properties of diffusion and osmosis. We also began discussing three important cell processes: photosynthesis, cellular respiration, and fermentation. Next week we will examine these processes in more detail and discuss the important process of mitosis.
