In this lab students will create a digital table and a graph based on information about the interactions of wolves and deer living on an island. This is a lab that was adapted from the Biology Corner website. I changed to so that I could incorporate the use of technology specifically aimed at spreadsheets via Google Docs. Hopefully when students are done they will be able to realize and visually see how populations of animal communities fluctuate.
This animation demonstrates how P-waves, S-waves, and Surface waves, caused by earthquakes move through different types of rock. The animation discusses what type of damage can occur, it shows seismographs for each rock type and discusses liquefaction.
