Flower Dissection

Second grade botanists investigated flowers in lab. After learning about the parts of a complete flower, we dissected a flower and used our hand lenses to observe the sepals, pistils, stamens, and ovaries. We know that the pollen on the stamens needs to find its way to the pistil, so that seeds can develop in the ovary. We sliced the ovaries open and found the small seeds. Ovaries on some plants grow into fruit. Discussion led to the role of pollinators. We also sliced the stems and water squirted out. The green color on our papers is chlorophyll and the pink is the pigment from the petals. Click here to watch an informative video about flowers.

Leaves

First grade botanists continued their study of leaves. We began lab with a discussion about why leaves change color and what happens to leaves after they fall to the ground. It is part of God’s perfect plan!

We practiced drawing leaves on our dry erase boards, noting differences in shapes and vein patterns. Then we “drew” with black glue. This activity helped us learn how to use a glue bottle correctly and to develop self-control. We will paint our leaves with watercolors next week.


While we waited for our turn with the glue, we used the side of a crayon to make a rubbing with leaf templates. There are 20 different leaves in this set.

Sunflowers

After a lesson about the parts and life cycle of a sunflower, my youngest scientists planted a sunflower seed. How long will it be before they sprout? Click here to watch a sunflower grow.




PreK scientists are studying fall plants, so we took a moment to look at some of the fall plants in the science lab.

The sunflowers in our root-vue have just begin to sprout!

There was a spectacular sunrise this morning! What a beautiful way to begin a Monday morning!
