Over the summer we studied plants for our science program. I’ll summarize our whole study in two posts.

REAL Science Odyssey started us out with learning the parts of a flower. We learned about a flower’s pistil, stamens, ovules, sepals, and petals. Satori discovered the purpose of flowering plants and pollination. We purchased flowers with the ability to see these parts in detail.

Here’s the worksheet that Satori filled out – “Color the Flower”. We then watched several BrainPop and Discovery Education Streaming videos as well as books.

We now appreciate flowers so much more.

During our seed study we learned about the difference between dicots and monocots, and what cotyledons means. We found examples of each in our pantry. I didn’t take pictures of these lessons, but we studied various seeds such as dry beans, lentils, peanuts, rice, corn, and popcorn. We discussed the various ways seeds can travel and their purpose for wanting to travel away from the parent plant. With REAL Science Odyssey, we are not daunted by the big scientific words as you can see. We did not do all the included science lab activities and worksheets, I skipped some that Satori already knew.

The last part of the flower we studied was the stem and roots. We learned the difference between xylem tubes (transport water) and phloem (transport food). Of course we did the classic experiment involving using celery as a stem. We filled three clear glasses with water dyed with food coloring – two with red, one with blue.

We stuck a celery stalk in the red glass (and eventually stuck one in the blue glass as well).  A white carnation’s stem was split and stuck in both a red and blue glass.

The next morning we noticed the first hints of color in both the celery and flower. The celery in the blue water had its leaves turn green and we could also see the xylem inside the stem all blue.


Below is a picture of our white carnation dipped in both colors, taken after four complete days. Half of it was blue and half was red.

I’ll be posting our final plant study event soon!

Our “Spores All Around” experiment was to demonstrate how the early plants reproduced with spores. As the first plants like mosses lived on land, they reproduced using spores. Our first moss and ferns were able to easily release spores to disperse in the wind, and still do today.

In this experiment, we are going to grow our own mold from these tiny spores that float in the air. We took a piece of bread, moistened it with a bit of water, then set it in a covered container. Satori watched to see nothing else was added. I told her that some spores will have set down in the moment we placed the bread in the container and shut the lid.

It took awhile, but two weeks later, we can see our fuzzy blue mold. I expected this to take place sooner, but we live in a dry, high altitude place, and it happened to be very cold this month. Perhaps all some of these factors slowed our mold growth.

In a few days, we will not open this container, but throw it all away.
