Written by Adi Ackerman, Head Teacher
A population is all the members of one species in a place, and it changes through births, deaths, immigration and emigration. There are 3 sheets for 7th grade here, each with an answer key. Vernal Pools and Amphibian Survival makes a scatter plot, Calculate Population Growth From Rates finds growth rates for fictional populations, and Invasive Species Fact File Organizer uses cane toads in Australia. The sheets practice MS-LS2-1 and MS-LS2-4.
