We’ll be wrapping up our botany studies in a couple weeks, but I have been meaning to post more of the lesson plans I have put together. If you missed any of the previously posted lessons, just do a search in the box above for “lesson plan”, and they should pop up for you.
This week, our botany focus is on transpiration, which is how plants transport water and nutrients from the roots to the very tip of the plant and then lose the water via evaporation through stomata on the leaves.
We will start off with these transpiration videos, courtesy of YouTube:
I printed this image to use as a coloring sheet for my girls:
I added quite a few vocabulary words to this lesson, which the girls should become familiar with, but Cole will be required to know their definitions, and spell them correctly. I expect Sydni (2nd grade) to be able to spell and remember quite a few of them.1. Transpiration 2. Xyelm 3. Phloem 4. Molecules 5. Evaporation 6. Cohesion 7. Solutes 8. Stoma/Stomata 9. Carbon dioxide 10. Osmosis
Most of the definitions can be found on Enchanted Learning’s Botany Dictionary, which is pretty cool!
Finally, we’ll be conducting both of the experiments found here, with the girls giving oral narrations, and Cole writing out formal science report forms. Everyone is familiar with the carnation in colored water, right? The other one is also very easy, and everyone should have a plastic bag in their home, with access to two small branches of some kind.
We will also try this one that explores the role of the stomata in transpiration. It’s another easy experiment, using common household items.
