There are several different ways that plants reproduce, including by budding or sending out shoots to make their own little babies, but today, we focused on flowering plants reproduction. After going through the parts of the flower diagram and discussing what each part does, we had the chance to look for them on real flowers! This is such a simple dissection, but great to introduce the idea of taking something apart, on piece at a time, and really looking closely at what is there. Additional InformationVideos:
Plant Reproduction in Angiosperms Join us as we explore flower parts, pollination, and double fertilization in angiosperms. We'll also talk about the importance of pollinators, like bees, and the role they play. Difference Between Angiosperms and Gymnosperms This video covers a little of the difference in their reproduction systems. The Plants & the Bees: Crash Course Hank gets into the dirty details about vascular plant reproduction: they use the basic alternation of generations developed by nonvascular plants 470 million years ago, but they've tricked it out so that it works a whole lot differently compared to the way it did back in the Ordovician swamps where it got its start. Here's how the vascular plants (ferns, gymnosperms and angiosperms) do it. Activities: Make New Plants, Keep the Old What could be more exciting than turning one plant into several new plants? Plant Life Cycle Activities These must-try experiments and activities will excite your students, get them writing about science, and most importantly, having fun while they learn about plants.

Plants make food through the process of photosynthesis (photo="light", synthesis= "putting together"--they put their food together using energy from sunlight). This takes place in the chloroplasts found in plant cells and can be explained pretty simply with the equation: water + carbon dioxide + light = sugar + oxygen
They quickly found that once they'd made glucose, there were a lot of oxygen beads left--which is why plants give off O2 and why we can breath--an important by-product of the reaction for sure! Hopefully doing hands-on modeling of the whole process helped them understand the process a little better.
With the youngest kids, we talked about how plants make food, not just for themselves, but for us as well. We looked at all the different parts of the plant and some examples of foods we eat that are each of those parts. Some were easy--like carrots are a root and spinach is a leaf, but learning that broccoli is a flower and corn is a seed was surprising for some of the kids. Additional ActivitiesVideos:
The Amoeba Sisters Photosynthesis This is the one we watched in class in case anyone wants to review again. Photosynthesis from Bozeman Science Another, longer, overview oh the process. Photosynthesis for Kids This is a great science video aimed to teach 1st to 3rd grade students learn about Photosynthesis and how plants are able to make their own food! The Most Amazing Thing About Trees Not related to photosynthesis, but another video that points out just how incredible plants are! Activities: Photosynthesis Relay Race This is a fun way to get the whole family involved! Look at the Stomata Under a Microscope. If you have access to a microscope, this is a pretty easy slide to prepare and it's fun to see where carbon dioxide enters the leaves to be used in photosynthesis. |
