The Effect of Natural Selection on Genes, Traits and Individuals
Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be laminated for repetitive use at stations where learners investigate adaptations, morphology, genes, and analogous and homologous structures.

Worksheet: The Theory of Natural Selection
Here is yet another variation of the classic activity in which lab groups use different tools to imitate different bird beaks as a demonstration of one of the factors in natural selection. What makes this one unique is that it is on a brightly colored worksheet and is followed by an assignment to write a paragraph about the occurrence of natural selection.

Discovering Rainforest Locations
How many rainforests are there, where are they, and do global factors effect their locations? These are great questions that have great answers. Children in grades four through eight use several different maps to determine why rainforests occur where they do and what environmental factors cause them to grow.
4th - 8th Science 39 Views 55 Downloads CCSS: Adaptable
Students explore a few key concepts associated with measuring biodiversity. They are told that biodiversity can be measured in a number of ways. Genetic diversity is a measure of the genes represented in the sample. Ecosystem diversity is sometimes used as a proxy for biodiversity since different types of animals/plants live in different habitats.
