Daily Objectives:

1.  Compare how characteristics of living things are passed on through generations, both asexually and sexually.
2.  Describe cross-pollination, noting male and female structures on an actual flower; make comparisons of an actual flower to a scientific diagram.  Explain how fruit structures compare to the flower reproductive structures.
3. Demonstrate scientific concepts through various illustrations, performances, models, activities.

Organisms reproduce sexually or asexually, and transfer the genetic information to their offspring.   MS-LS3-2
Today in Class:
1  Each group double-checked the labels on their flower structures.  These should match with your flower diagrams that you drew last week.
2.  Next, each group received a slide with a sample of Lily or Alstroemeria pollen.  You should have focused on the pollen on low power magnification and then to medium;  some groups went on to focus on the pollen using the high-power objective. You should have then drew a scientific drawing of the pollen, with shading and detail.
3.  Third:  each group received a half of an apple.  Your goal was to determine how to match the parts of the flower with the parts of the apple.  You labeled and apple diagram and then answered the questions associated with the apple and pollination.
Review and study your notes (Genetics & Heredity, Mendel, traits,…), using the storytelling method.
