Warm Up: Two species of buttercup can be found in the same field in South Dakota.  They emerge at different times: one species emerges and flowers in early spring, and the other species emerges in late summer, after the first species has set seed. Both flower species are pollinated by the same insect species, which is common in spring and summer.  The different flowering times are likely due to

Rabbits were introduced to Australia about 100 years ago for the purpose of hunting.  They have been multiplying, eating up the native vegetation, and destroying the native habitat of other small animals, ever since.  In the 1950’s, in order to control the rabbit population, government scientists released the myxomatosis virus.  The virus, which dramatically reduced the rabbit population, is an example of ____________________.

Earth Science:

–Whole group: video Discovery Channel – Large Asteroid Impact Simulation (4:46)



Start vocabulary for this section (Word-definition-picture): solar wind, meteoroid, meteor, meteorite, chondrite (5 words; p. 73 & 74).

You have 25 minutes to work on vocabulary. Vocab graphic organizers will be graded tomorrow.

A laboratory experiment followed the growth of a flour beetle (Tribolium sp.) population over time.  At first the population increased dramatically but later growth slowed and the population size leveled off. While food (the wheat flour in which they live) was abundant, it was noticed that flour beetles resorted to eating their own eggs when densities got high. What can we conclude about cannibalism in this species?
