CONSTRUCTION OF A HEMOGLOBIN GENE
High schoolers use research to see how eight pairs of triplets are equivalent to part of a gene and control a part of heredity. They also understand how red blood corpuscles manufacture normal hemoglobin.

Why do we need Vitamin C in our diet? Or Why do we carry old inactive genes in our genome?
Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...
Curated OER
DNA Blueprint for Life
Students isolate DNA from different food sources. For this biology lesson, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.
Curated OER
Lost Baby
Learners simulate the steps involved in creating a DNA fingerprint by the RFLP technique. They analyze RFLP patterns to determine the parentage of a missing baby.
Curated OER
Characterizing Drosophila Mutants
High schoolers investigate wild-type and several mutant varieties of Drosophila melanogaster, which are characterized and distinguished according to pteridine pigments. They discoverthat paper chromatography of the wild-type...

Controlling the Code: Molecules at Work
In this DNA worksheet, students access a website to learn about how single-celled organisms function successfully. Then students pretend they are a bacterium and determine how to transport lactose across their cell membrane for food....
Curated OER
Insect Classification
Students compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.
Curated OER
Creatures That Glow In The Night
High schoolers investigate the different bioluminescent organisms. They use microscopes in order to make observations and draw what is seen. Students demonstrate they have studies the differences between the process of photosynthesis and...

What Can Pseudogenes Tell Us About Common Ancestry?
Students compare/constrast DNA sequence data for a portion of the rat GULO gene to the corresponding sequence in the inactive GULO gene in humans, chimpanzees, orangutans, and crab-eating macaques by identifying the shared sequences in...
Curated OER
DNA Extraction Laboratory Experiment
Students will visualize how DNA is extracted from cells by performing a simple laboratory experiment. They will then use this knowledge to further understand how scientists are using DNA extraction to try to clone human cells, and to...

Digestive System
In this digestive system worksheet, students answer a list of true/ false questions. The students answer questions based on their knowledge of each process of the digestive system.
Curated OER
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.
