leaf vein specimen

Plants have veins—like blood vessels in humans—that carry water drawn up from the ground to the tips of stems and leaves, and circulate the nutrients produced by photosynthesis.
How about turning those veins into a specimen? Heat a sodium hydroxide solution and place a leaf in it.
After about 20 minutes, take it out and gently brush the surface with a toothbrush; the leaf tissue will come off, leaving only the veins! You’ll likely think, “I can’t believe they’re spread out this much.” If you soak it with ink, it will look even more vivid!
In conclusion
I hope you can find an interesting topic—one that your teacher will praise—among the various themes.
In your fourth-grade independent science study, observe the nature around you and experience the joy of discovery through simple experiments.
Be sure to share what you’ve learned with your friends and family.
By engaging in self-directed science that interests you, your curiosity about nature and science will deepen even more.
