In this biology learning exercise, scholars color and label the chemiosmosis process and complete four short answer questions on ATP synthesis.

The spread of an infectious disease can be a complicated process. Using a game approach, learners reenact the spread of the West Nile virus. They learn the need for the vector in transmitting the disease and how different organisms react...

Students explore the concept of cell phone plans. In this cell phone plan lesson, students research the cost of cell phones. Students compare various cell phone plans and decide on which phone plan is best for them.

Student observe and quantify the respiration that occurs in yeast-molasses cultures. They complete an effective experiment in order to examine how to think critically about the results.

Learners explore the structure of a plant cell. They carefully peel a single layer of onion skin from a slice of onion and stain it with methylene blue to observe the structures inside. They use a Digiscope connected to a computer to...

Learners explore how DNA fits into chromosomes and how chromosomes relate to the human body. They learn about DNA replication and protein synthesis and model these two processes in Web activities.

Students microscopically observe various subcellular components. They determine the effects of different salt solutions on Elodea plant cells. Students explain the major function of a cell membrane and describe its structure.

Students use the table feature of Microsoft Word to construct a solvable maze. They incorporate clip art and WordArt into their mazes. Students create a table and use word processing functions to design a maze. They create competency in...
