5th Grade: The 5th graders have been wrapping up our study of vascular plant systems. We've done some reading about vascular plants this week, and today, we'll be studying different vein patterns in leaves we find around the school yard. 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?
4th Grade: The fourth graders are starting to work with living organisms. Besides the class gecko, we now have a mini aquatic ecosystem. Our fish tank includes goldfish, pond snails and plants. The plants provide oxygen to the water and the snails are cleaning up after the goldfish, so it's a nice balance! We also have started our observations of live beetles and isopods. Here are some pictures for reference:
Darkling Beetle:
Isopod:
This week, our focus has been on simple observations on behavior and physical appearance. In the next few weeks, we'll use the critters to explore environmental preference.
Key Questions:
- What did you notice about your isopods and beetles? How were they similar? How were they different?
