In this science activity, middle schoolers examine the topic in order to solidify knowledge covered in the curriculum using puzzles and creative games.

Students study how standards are established in Science. They also look at the value of different perspectives with questions about ecological standards. The class creates its own standards for ecology with the help of a survey to obtain...

Students assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.

Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.

In this biology worksheet, learners are introduced to the practices of safety as related to using a laboratory and then answer some questions as an assessment.

Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

Students investigate nearby forests and record their interactions with trees as well as wild life.  In this ecology instructional activity, students read the book, In the Woods: Who's Been Here?, and attend class observational field...

Studens brainstorm ideas about the ways scientists think. In small groups, studentds create a definition for one or two "habits." Students develop a set of questions to be used by the entire class in a series of interviews. Students...
