In this week’s lesson we learned all about cells, the microscopic units that are the building blocks of all living things. Students discussed the size of cells and investigated all the microscopic parts or “organelles” that have important jobs within each cell. They then had a chance to show off their knowledge. With every correct description of cell’s organelles, the young scientists were able to build cell models; they received that part of their model (eg. plastic bag for cell membrane; ping pong ball for nucleus). Their favorite parts of the model were the artificial snow that represented the cytoplasm and the miniature pigs representing lysosomes!
This was an interactive way for students to learn about and build their own cells. For easier understanding, every part of the cell was related to things you would find in a city (eg. nucleus was city hall as it is the “planner” of the cell and mitochondria are the power plants). By the end of the lesson, everybody had a complete cell model, and a better understanding of the inner workings of the cell!
