Give your biology students a focused look at trait frequency over time with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Students will answer questions such as "Which of the following can cause changes in trait frequencies over time?", "What is one way environmental changes can affect trait frequency?", and "What is the relationship between trait frequency and genetic variation?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a standards aligned biology unit. The unit also covers Fossils as Evidence, Patterns in the Fossil Record, Comparing Anatomical Structures, Inferring Evolutionary, Embryology and Evolution, and Developmental Patterns, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 7 biology classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-LS4-6.
