Since we have finished FCAT, I am thrilled to have time for science again! This week, we kicked off our unit on heredity and reproduction, starting our study of sexual reproduction in flowering plants. Here's a sample of the language we've been using:
We'll continue to look at pollination, fertilization, and seed dispersal over the next week or two.
UPDATE 4/25: Today we used plastic cups, corn starch, sand, cotton balls, and our hands to make a model showing what happens when flowers pollinate:
We recorded our observations in our Science Interactive Journals.
We discussed what each part of the model represents: cups (
flowers), corn starch and sand (
pollen), cotton balls (
nectar), and our hands (
pollinators). Just like in the natural world, our "pollen" stuck to everything!
We've also learned that different kinds of plants have different life cycles. Some plants produce flowers as part of their life cycle. Other plants, such as pine trees, produce cones. Today we found a female pine cone on the playground. We're still on the lookout for a (male) pollen pine cone, which looks something like this:
