Seventh graders trace a piece of food through the digestive system. They describe the functions of the mouth, esophagus, stomach, etc.

Seventh graders trace a piece of food through the alimentary canal and differentiate between mechanical and chemical digestion in several different hands-on activities related to digestion.

Young scholars learn about the four biochemicals that are important biologically. For this biochemicals lesson plan, students identify the four major groups of biochemicals including carbohydrates, proteins, lipids and nucleic acids....

Twelfth graders simulate a DNA fragment running through a gel electrophoresis in a class activity. Students work in teams as a DNA sample with each person on the team representing a fragment that moves through the gel at a specific speed.

Students engage in DNA manipulation using forensics techniques. Students investigate topics involved in forensics studies such as cloning, electrophoresis, gene mapping, replication, and transcription.

Seventh graders explain the mechanism of digestion. In this biology lesson, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

Students differentiate chemiluminescence from bioluminescence. In this biology instructional activity, students explain how fireflies and other animals emit light. They discuss the applications of engineered bioluminescence.

Students investigate the process of hydroponic agriculture. They grow beans in different hydroponic solutions, compare results and graph their observations.

Students explore how PCR works through various activities. In this biology lesson, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.

Students analyze the calcium content of egg shells as an introduction to the toxic effects of pesticides on biological systems.

Students discuss DNA Fingerprinting and gel electrophoresis before participating in a crime solving activity. Students simulate their DNA using adding tape and complete the steps necessary to do a gel electrophoresis. They discuss the...

Young scholars discuss decomposition, bacteria, fungi and other microscopic organisms. They participate in an experiment to grow fungus on bread. As the fungus colonies grow, students observe them under a microscope to identify and...

Students construct a plsmid model with the materials provided and be able to use it to define certain terms and explain other practical applications of genetic engineering. This simulation allows the students to work through the diagram...

Young scholars complete a pre-test on the relationship between heredity and the environment. As a class, they write down descriptions of themselves and identify which traits can be changed and not changed. In groups, they determine...

Students are introduced to mapping by crossover frequency. Genes travel as packaged trains on chromosomes. They use this experiment, genetic mapping assignment, that allow students to quickly complete the assignment and yet examine the...

Learners use a variety of creative writing tools within this assignment: poems on particular organ systems, write a short story and/or create a word graph. They are involved in a demonstration of lactic build up in the muscles, a...

Students research and define a muscle biology research question and organize an experiment to address the question utilizing either NADH staining or acid buffering. They analyze data as well as draw conclusions about their research....

Students investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to denature...

Students create glue from milk by curdling milk with an acid. In this protein denaturing lesson plan, students experiment with milk and vinegar to denature the proteins in milk, create curds and whey and use the curds to produce glue by...

Young scholars extract DNA from green peas. In this DNA extraction lesson plan, students use a blender to chop up peas, they mix them with a little soap, they tenderize them and they mix them with alcohol to see the DNA precipitate...

Learners investigate the process of genetic engineering. In this genetic engineering lesson plan, students use paper models of DNA and plasmid bacterium to investigate the process of replicating DNA, splicing genes from DNA, and...

Students explore digestion. In this Human Body lesson plan, students participate in six different activities pertaining to the Digestive System. Students gain understanding of digestion through experimentation and investigation. Students...

Students investigate stereoisomers using models that can be rotated and manipulated. In this stereoisomers lesson plan, students try to make models of molecules look alike by rotating the bonds. Using a mirror, the teacher demonstrates...

Young scholars experiment with milk to understand the importance of pasteurization. In this pasteurization instructional activity, students learn background knowledge about bacteria in milk and the process of pasteurization. They...
