Up close and personal!
Today we made slides of plants and looked at them through the microscopes. They were purple and green and they were very cool to look at. We took samples from plants in our room. We chose Mother-In-Law Tongue, Coleus, and Chrysanthemum. We also looked at prepared slides of algae, onion, and pine tree. They all had veins. We also noticed a pattern. Many of them had stripes, or circles or geometric shapes. We were surprised to see that. Some of us thought we'd just see one large piece. Instead we were impressed to see lots of little circles and squares joined together. They are cells. There were dots inside a lot of the circles and squares, too. One more thing we did was look through a strong magnifier at a pea pod. It looked hairy. It was very 3-D-ish. Very awesome.
Our space seeds and earth seeds experiment is going well. We have sprouts. Some of the sprout stems are spreading out in a V toward the leaves and some are just straight. The ones that are more grown have more circular leaves. The ones that have just gotten started have more pointy leaves. The dirt in the space container seems to be grayer - weird.
