JMG–Plant Growth and Development

Lesson #1 & #2

# 1 - Importance and Uses of Plants

We are learning how plants are used in our every day life this week.  We have talked about what our world would look like without plants :

  • we could not breath
  • animals would die
  • no clothes
  • bugs would die

For our project we are going to make a plant sandwich by pressing a flower or plant leaf in between some paper and put it in a thick book to press it out.

#2 – Plant Classification

Our next task is to talk about how we can group different plants to help us identify them and learn more about them.

We talked about

Monocot – parallel veins

Dicot – netted veins

and we collected different leaves from around our house as examples to make rubbings from them.

We also talked about different kinds of leaf edges – another way to identify a group of trees – and study similarities.

Entire – smooth edge 

Serrate – obviously a serrated edge

denticulate – a very tight jagged edge

lobed – big loopy lobes

We were able to find each leaf edge type – but only dicot leaves here around our house.

I think the kids learned some, but certainly got excited about learning more nature stuff, they had fun making rubbings and identifying their leaves.  I know we are going to love this program!!
