Are Woolly Bears Nocturnal?
Dannah N, Carson T, Byron V, Angela A, Matthew B
We were curious to see if Woolly Bear caterpillars were nocturnal. Our experiment tested Woolly Bears in the dark, & during the daytime to see if they were active. We used a shoebox to demonstrate this.
Do cukes cause the demise of Hissers?
James H, Sarah M, Dillon S, Mason W
In researching our Hissers we found an article that said if Hissers ate cucumbers they would die. We wanted to become our own myth busters. So, we experimented on Hissers to prove if cukes would really be the demise of them.
Is Knapweed my only choice? (Exploration in host specificity)
Laura B, Will M, Sam P, Grace S, Mathia O, Chandler H
The biological control agent, Root Boring Weevil was utilized at Tamarac National Wildlife Refuge to control the invasive plant, Spotted Knapweed. This aggressive weed displaces native species and can eliminate habitat for native animals. Our group wanted to see if the Root Boring Weevil demonstrated host specificity for Spotted Knapweed or if it might adapt to utilizing another plant species. Weevils were placed in a container with Spotted Knapweed and Canada Thistle. The Weevils moved on each plant but were only seen boring to lay eggs around the base of the Spotted Knapweed plants.
