A complete overview of oxidation, reduction, and how electrons are moved in respiration. You could use this slide show to elaborate on the concept of harvesting stored energy, and to summarize the stages of aerobic and anaerobic metabolism.

High schoolers explore the spherical protoplasts of plants. Students observe that plant cells have a plasma membrane in addition to the cell wall. High schoolers plasma membranes, solutes and organelles.

In this word search worksheet, students locate words related to biology. The word list includes protists, viruses, plants, spiral, and biotechnology.

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

Young scholars create a model of DNA and simulate replication with their models in an activity that uses licorice, colored marshmallows, and toothpicks. Students also label a diagram of replication and indicate major parts of the DNA...

Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...

Ninth graders explore protein synthesis. In this DNA lesson students complete a worksheet and a DNA lab activity. 

Students construct various virus models using Fruit loops and Alphabits to represent nucleotides and molecules. They constructs capsomeres using shoes as the capsomeres and discuss various viruses.

Brown rice contains vitamins B and E, while white rice lasts longer in storage. The availability of rice around the world makes it a great candidate for genetic engineering. Scholars apply their knowledge of genetic engineering to solve...

Students are introduced to DNA microarrays. They discuss how scientists and doctors use them and how they work. They complete a worksheet and discuss their findings.

Students explore the process of evolution. They examine examples of how homeotic genes may work and obtain gametes. Using a microscope, students observe the fertilization of sea urchins. They video tape the process and write a...

Students write an essay on the basic steps of the DNA replication process accurately enough to show a complete understanding of the subject. Finally, student correctly identify the polarity of the template strand and match the correct...

Reactions in cells must be regulated and one way to do this is using allosteric molecules. These regulators can activate enzymes or inhibit them. This tutorial explains exactly how allosteric regulation works using words, narration, and...

In this biology simulation, students discover what factors influence the action of enzymes on cellular work. Students will first explore the action of enzymes through a simulation in which their hands are the enzyme "toothpickase" and...

In this biology lab, students use pineapple juice as an enzyme, and jello as a substrate to illustrate an enzyme/substrate complex.
