Plant Lessons

Yesterday I learned about leaves.

Leaves are green from a chemical called “Chlorophyll”.

Chlorophyll is a green pigment that helps the sun absorb energy.

Plants use that energy to make food.  This process is called “Photosynthesis”.

I also learned about two kinds of trees: coniferous and deciduous.

Coniferous trees are trees that have needles and cones , like a Christmas tree.

Deciduous trees are trees that have leaves, like a maple tree. 

Q: Why do leaves change color from green to brown, red, and yellow?

A:  In the fall, the chlorophyll disappears and the other pigments can be seen.

Pumpkin Seedlings

Those are pumpkin seeds that I grew.

I put the seeds in a wet napkin.

We put it in a zip-lock bag so the water wouldn’t evaporate.

Now I have to put it in a pot with soil.
