Come On Spring!

We're so excited about all the new growth that showing up everywhere!

In our classroom, we have been fascinated with our space and earth seeds. We have over 20 sprouts in each planter. The leaves of the ones that are the oldest are starting to stretch out into oval, rather than being circles. They have noticed that newer plants have tiny stems and 2 thin leaves. The stems sometimes look purple or red. When they get older 2 more leaves form between the other two and then even more leaves grow from there, too.














Something interesting has happened in our earth plants. Not only do we have a stranger (that we think is grass) mushrooms grew there this week! We know that they are decomposers, but we aren't sure what it's decomposing.














The rest of our time we spent researching the different plants we have in our classroom. We are going to make little pod casts about them. We were very productive today!

Spring weather!

Today we checked on our seed experiment. We have 25 sprouts from the earth seeds and 20 sprouts from the space seeds. Each planter has a stranger. The earth planter has a plant that looks like grass. The space planter has a plant that has bigger and fatter leaves. It also looks fuzzy on the stem. These strangers probably just came from the soil.
We also looked at onion skin slides. We looked at them under the microscopes. The onion cells looked like rectangles, really long rectangles. Their corners were kind of rounded. But they were all stacked together like legos. We dyed one sample with iodine to turn the cells yellow. We hoped that the nuclei would should up better, and they did. :) It was cool.
