Students explore the concept of dominant and recessive genes by examining the dominant and recessive characteristics of a game of rock, paper, scissors. In small groups students play the game and explain how one move is dominant over...

Students use the indicated text and the internet to compare and contrast the North and South. They discuss the social and political implications of the two predominant economic systems (slavery and factory). They are introduced to the...

Fourth graders identify rocks in this discovery lesson by examining rock characteristics and processes. They identify basic properties of minerals and rocks. They revise their theories of the natural world, once they see and learn new...

In this chemistry worksheet, learners practice creating the correct chemical compounds in theory using the lewis structures in the applied problems.

In this origin of life instructional activity, high schoolers will review the different theories on how life originated on the Earth including the experiments conducted by Louis Pastuer, Francesco Redi, and Miller and Urey. Students will...

In this earth and space science activity, students complete a crossword puzzle given 9 clues and a word bank on topics such as sea floor spreading, tectonic plates, faults, lava and the big bang theory.

In this Pascal activity, students solve word problems dealing with probability and patterns based on Pascal's triangle theory. Students complete 10 problems total.

Students develop an understanding of natural selection, specifically, how it unfolds from generation to generation. They work in small groups to perform an experiment using beans. They use a worksheet imbedded in this plan to guide their...

Students view video showing recent field work on a twenty two-year study of finch beaks on a small island in the Galapagos, showing natural selection clearly operating in the wild.

Learners count the number of varves (annual layers of sediment) in shale billets, taken from the Green River Formation in Wyoming. The count is then extended to reflect the entire 260 meters of sediments where the billets originated.

Learners are taken on a simulated "voyage" backward in time, to the beginning of our planet. They "witness" that beginning, the origin of life, and a number of key events from then to the present.

Students transfer examples (names) of primates from their location in an outline hierarchy of primate groups into a set of nested boxes reflecting that same hierarchy. A cladogram can then be drawn illustrating how these groups are...

Students are guided through a process in which three questions are addressed by retrieving beta hemoglobin sequences from online databases, and using online tools to compare those sequences in student-selected animals.

Students compare differences in amino acids in the beta hemoglobin from representative primates, complete a matrix of those differences, and from these data, construct and interpret cladograms as they reflect relationships and timing of...

Students examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino acid...

Students construct cladograms (evolutionary trees), showing how shared derived characters can be used to reveal degrees of relationship. They interpret and analyze cladograms, and determine where unclassified vertebrates would fit on a...

High schoolers go on an imaginary fossil hunt. They follow a script read by the teacher, students "find" (remove from envelope) paper "fossils" of some unknown creature. They attempt to reconstruct fossil pieces into an animal.

Young scholars role-playing the concept of evolution through naturally occurring mutations. Working in pairs, they model how birds have adapted to the food sources in their environment through changes in their beak size and shapes....

Learners are shown why they should care about evolution. They become specialists in one sphere influenced by evolution and then share their findings with their group. Students are lead into a class discussion, so that each student can...

High schoolers examine the controversy surrounding evolution --- the challenges to science, the battles over teaching evolution in the schools, and the reconciliation of religion and science. They also examine an interactive time line...

Students research pertinent solar system formation and Earth development events and work together to determine which events occurred first, second, third, and so on. Students arrange themselves as a human timeline across the room. ...

Young scholars recognize that achievements of human beings throughout human history can be considered part of the ongoing story of human evolution. They research settings such as the biosphere and Mars and write imaginative short stories...

Students investigate the importance of sexual reproduction in evolution. In this sexual reproduction lesson plan, students simulate species with two traits: eye and skin color. They determine what characteristics are beneficial for the...

For this Hubble's law worksheet, learners use data for galaxies which include their distance and speed. Students make a graph to show the distance to each galaxy and the speed of each galaxy. They use their graph to answer 4 questions...
