Students in Mrs. Erbland's 3rd grade class will use this space to write about themselves, their classroom, and the work they're doing for our HP grant project.
Before our first trip to Mill Creek in Webster Park, we had some questions. After we visited the park, we looked over our data and observations and found the answers to our questions. But, then we had more questions.

How does the temperature (air, water, soil) change throughout the different months?
The temp. will get colder and then begin to get warmer again.
When we go in January, we think that the temperatures will be colder. It is possible that the soil may be the same.

Does temp. affect the number and types of macroinvert.?
No, there is probably enough food and oxygen for them to exist in the colder months.

We think there will be less macroinverts. Than there were in October.

What examples of seasonal changes will we observe (plants and animals)?
The trees will loose their leaves in winter and get them back in spring. Animals will hibernate in winter and come out in spring. Soil will become muddy. Leaves will turn colors. See less animals in the winter. Will be very cold in the winter, it will be sunny when it is warm. Less people in winter. Snow in winter. Creek might be icy in the winter. More people in the spring. Some of the organisms might die in the winter.

The creek might be icy. The ground may be white because it is covered with snow. Ground will be frozen and cold when you touch it. Paved areas will be slippery. Grass could be wet and soft. In the fall the creek was running. There was a drought and the creek bed was smaller than usual. There were more rocks and mud. The creek might be frozen but the rushing water may keep it from freezing over. We can’t agree on whether the creek will be the same size, smaller or bigger. The trees might be white. They will have bare branches. We might only see a few mammals, the rest will be hibernating.

Will the pH of the water change throughout the different months?
Snow might affect pH. Weather might change the pH of the water. pH will stay the same because not a lot of people will be there to affect it. pH might be in the middle more in the spring because it is warm and cold.
The pH will change, it will go down.

Does pH affect the number and types of macroinverts. ?
Yes, if the water is more acidic or basic not as many organisms can live in it.

Does the observation of macro-inverts. Give us info. About water quality?
It does, if it’s lots of leeches, the water might be polluted. If we find a large number of “fussy” organisms, the water will be clean.

Can we determine which location in Webster has the best water quality?
We could share our data and see who has the best by looking at pH and seeing how close to 7 it is, temperature is it cooler so it has more oxygen and more good organisms can live in it, the macroinverts. Will tell us if the water is clean or not.

We think that the Arboretum will have the best quality water. We think that North Ponds is maybe polluted. People may think that Mill Creek is so small, that it won’t make a difference what they do to it.

We have spent the last 6 months learning about the living environment through the Pond Partners Project. We began by researching each of the areas that the 3 classes visited. We then wrote short blurbs for each one. We put them in our handhelds and beamed them to Mrs. Erbland. She put together what we had to say and created a paragraph for each. These are posted at each location's site. We learned about macroinvertebrates and then we became interested in invasive species. We chose the zebra mussel to study further. We spent our time at Mill Creek in Webster Park. We did take a virtual side trip to North Ponds Park where we studied the Canada Goose. You could call them an invasive species too.
