In Science Class . . . Week of 1/17

The 4th and 5th graders have been wrapping up our study of vascular plant systems. We watched a video on plant structure and growth earlier this week, and yesterday, we studied different vein patterns in leaves we found around the school yard. Thanks to the huge wind storm, there were a ton of great options around! Here are some examples:

Palmate:
Pinnate:


Parallel:


Key Questions:
  • How do vascular plants get water and sugar to cells? (Xylem transports water up from the roots, while phloem transports it downward to other cells. Both xylem and phloem are part of "veins" that we see on leaves.)
  • What leaf patterns did you see in your leaves that you collected?
