Dinnertime on the African savanna is a highly choreographed event! Introduce young ecologists to the concept of niche partitioning through a hands-on activity. Pupils research animal behaviors and use data to develop an understanding of...

High schoolers conduct a series of activities to explore the nature of cells. In this biology instructional activity, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.

High schoolers build DNA strands and practice base pairing rules using an interactive website in this technology-based lesson for a high school science class. This lesson includes links to the interactive website, a worksheet, and a...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Students study the history of DNA and how to extract it. In this genetic lesson students complete a DNA experiment using bacteria.

Tenth graders research the history and discovery of DNA. Using their text, they label a basic DNA structure and the composition of genes. They explain how RNA and DNA differ from one other and discuss the processes of transcription and...

Learners conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.

Middle schoolers discover the basics of fingerprinting and how it identifies a person. They create their own fingerprints and compare them to classmate's to determine that no two people have the same identity because of fingerprints....

Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.

Seventh graders describe the basic structure of the DNA molecule. They identify what an inherited trait is and how it can be determined by one or more genes. Finally, 7th graders identify that plant and animal cells contain several...

Students explore the cell and cell processes. They create "cytoplasm", make a model of the cell and its organelles, and simulate the osmosis and the diffusion of materials into and out of the cell.

Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

Students compare mitosis and meiosis with regard to chromosome number in parent cells versus daughter cells, types of cells produced, total number of cells produced, and the number of divisions. In groups, identify and differentiate the...

Students explore biotechnology through various activities. In this biology lesson, students analyze its pros and cons. They study and read informative articles about biotechnology.

Sixth graders will simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups will already be...
