2. Jane Goodall spent countless hours among the chimpanzees doing scientific research.  In her research, Jane learned that chimpanzees use stems or long blades of grass as tools to "fish" out a tasty meal from termite mounds.   How did Jane learn this about the chimpanzees?  This qualitative research is based on Jane  following the chimpanzees, taking notes and making careful  _______________
Submit
3. One day, while watching the chimpanzees, Jane Goodall saw something peculiar. She watched as a chimpanzee looked into a hollow in a tree. The chimp picked off a handful of leaves from the tree and chewed on them. Then the chimp took the leaves out of its mouth and pushed the leaves into the tree hollow.  When the chimp pulled the leaves back out, Jane saw the leaves sparkled with a gleam of water. The chimp then put the leaves back in its mouth. What was the chimp doing?  How did Jane think through this experience?

4. Plant Organelle Word Bank 
Cell membrane Chromatin Endoplasmic Reticulum  Rough Nuclear membrane Plasmodesmata
Cell wall Cytoplasm Endoplasmic Reticulum Smooth Nucleolus Peroxisome
Centrosome Golgi Bodies Mitochondria Nucleus Ribosomes
Chloroplasts    Vacuoles
 Use the Plant Cell Organelle word bank as you work to identify the parts of the plant organelle diagram. Identify Organelle # 4: # 4 is modeled as a green (because it contains chlorophyll), bean-shaped organelle. Photosynthesis takes place in this organelle, changing sunlight to chemical energy (food) for the plant.
Submit
5. Plant Organelle Word Bank 
Cell membrane Chromatin Endoplasmic Reticulum  Rough Nuclear membrane Plasmodesmata
Cell wall Cytoplasm Endoplasmic Reticulum Smooth Nucleolus Peroxisome
Centrosome Golgi Bodies Mitochondria Nucleus Ribosomes
Chloroplasts    Vacuoles
 Use the Plant Cell Organelle word bank as you work to identify the parts of the plant organelle diagram.  Identify Organelle # 12: # 12 is modeled as a purple sphere that contains many smaller organelles. This structure controls many of the functions of the cell and contains DNA (in the chromosomes).
Submit
6. Plant Organelle Word Bank 
Cell membrane Chromatin Endoplasmic Reticulum  Rough Nuclear membrane Plasmodesmata
Cell wall Cytoplasm Endoplasmic Reticulum Smooth Nucleolus Peroxisome
Centrosome Golgi Bodies Mitochondria Nucleus Ribosomes
Chloroplasts    Vacuoles
 Use the Plant Cell Organelle word bank as you work to identify the parts of the plant organelle diagram.  Identify Organelle # 3: # 3 is modeled as a large membrane-bound space within the plant cell. It takes up much of the cell. It helps keep the shape of the cell, storing water and waste liquids.
