I know we are a little behind on the Green Hour Challenges. We just got off track a little but we are back! We plan to catch up when we can and post as we go along.
Today we ventured out to the meadow in our planned neighborhood to do #9 – One Small Square. We probably should have selected an area randomly, perhaps by throwing a hoola-hoop out and studying the area in which it landed. However, the kids wanted a shrub in their study plot assuming it would provide more interesting discoveries. I figured I could introduce scientific sampling methods when they are older. 😀
This first picture shows the kids working together to investigate a small hole they discovered. They found a stick and used it to poke down in the hole to find out how deep it was. The hole was as long as the stick (about 1 foot) but it also turned as it went deeper so I imagine it went even farther. There were holes all over the meadow and we hypothesized that small field mice probably lived in them and that the holes were connected by underground tunnels. We plan to do a little research to learn more.
We also got out the loupes and looked at the small plants that were sprouting. We were surprised to find mostly dead grass. There were only 3 different types of small plants growing – 4 if you count the shrub which I think was Bitterbrush (hard to tell yet without the foliage). We were surprised to see only 2 insects (one small black ground beetle and a few ants) – we even dug small holes beneath the grass.
We spent about 20-30 in the meadow and then meandered over to the pond. We were hoping to find tadpoles as the kids have been wanting to catch some to observe the metamorphosis. Again, it seems spring is late in arriving to Central Oregon. We saw only a few water striders and whirligig beetles. Three Canada Geese observed us from afar.
The kids were delighted to get out again. We had intended on starting a year-long tree study, but our goals morphed as we were underway. We captured a few aquatic insects and the kids wanted to bring them home to observe more closely. We have two small habitats that the kids received as gifts some time ago but discovered when we added our specimens that they are much too small and are more of a cool-looking toy than a true aquarium for scientific study.
Both habitats are products of Summit Toys and are a great idea in theory. Put to use, however, I am not impressed. The water in the frog habitat splashes out and leaks out the bottom when the kids try to move the habitat to see different angles and there is so much plastic inside that there is very little ‘liveable’ space for the critters. The bug habitat is too shallow to add any substrate. My thought is that these toys are designed for one-day use and not long-term observation. I would not recommend these to families interested in studying insects or rearing tadpoles.
