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.
