The mysterious nest-like area that Matt and Jeff are studying. Did a creature make it? |
| Matt measures and looks for clues while Jeff records their observations. Scratches? Claw marks? Fur? |  |
 |
Pat leans in to investigate. |
| Wayne wades right in. |  |
 |
Mark and Kay focus their attentions on a zippy little bug species that scoots across the water near the drainpipe. |
| Still enjoying the waders, Joanne remains steadfast in her explorations. |  |
 |
One group suspects pollutants from the drainpipe affect the creek water by the train tracks, judging by peculiar foam and strange red plants in the water nearby. |
| At right, the unusual red plant--or might it be roots?--growing near the train tracks. They notice that the red is more intense in faster water. |  |
 |
Curious about the types of plants growing in different creek conditions, Peter and Eric gauge water temperature. |
| Continuing their investigation, Peter and Eric test the speed of the current by floating an orange, timing its speed over a certain distance. |  |
 |
The red plant investigators wrestle with newfound observations that throw off their initial assumptions. |
| At the end of the day's outdoor explorations, Joanne's happy thumbs sum up the groups' feelings about the creek inquiry. |  |
