Predator/Mosquito Inquiry• To determine the effectiveness of two different mosquito
predators, three isolated pens were created in a large empty warehouse. Mosquito populations were placed into each isolated pen and the population was sampled once each week by placing netting near a tub of water for 15 minutes. Mosquitoes caught in the net were counted and released. Once mosquito populations were stable, bats were introduced into one isolated pen and dragonflies were introduced into a second isolated pen. The third pen did not have any predators. The number of mosquitoes collected each week is recorded in the following data table.

Read p. 35-39 and use a periodic table; complete the following charts
• Create a table with the following categories:• I know this term• I have heard of this term before• I have no idea what this term means
• Create a chart of the first 20 elements that includes the symbol, atomic number, number of protons, and number of electrons. Leave space for 3 more columns. (hint: see Inside back cover)
