It's A Cell


Today in Co-op Class the children learned about the last days of Creation. The listened to stories about this subject and had a snack of different types of fruits. Mrs. Friesen, the teacher, had the children looking through a high power microscope at plant cells and human cells. After this the children made cells using a ziplock bag, jello, a grape and a couple of raisins. She got this activity from a science curriculum called, God's Design For Life, by Richard and Debbie Lawrence. Our cells have 5 parts (the children made these): 1. The Cell Membrane, represented by the zip lock bag 2. The Nucleus, the "brain" of the cell, represented by the large red grape 3. The Vacuoles, which are storage "warehouses" that store food for the cell 4. The Mitochondria, the cell's "power stations", represented by the raisins 5. The Cytoplasm, represented by the jello In addition to these 5 parts, plant cells also have: 6. The Cell Wall, represented by a shoe box 7. The Chloroplasts, the "power plants", where plants make their own food, represented by green grapes (cut into 4th's)
