The 2005 version of the Regents High School Examination in the area of ecology is as comprehensive as previous years' exams. It consists of 40 multiple choice questions on everything from the structure of DNA to the interactions within...

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...

Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

This assignment begins with an 8-page article about Sam Berns, a young man who suffers the rare genetic disease called progeria. Progeria is caused by a gene mutation and manifests itself as rapid premature aging. When your biology class...

For this genetic change worksheet, students read about how mutations can occur in germ cells and somatic cells. Students complete 1 multiple choice and 4 short answer questions.

In this biology instructional activity, students identify and label the diagram shown by stating what each part of the diagram represents on the line. Then they use the DNA strand as the original strand and complete the data table....

Students participate in a contrived natural selection simulation in which they build and modify simple paper airplanes. They study divergent and convergent evolution and how it is isolated in sub-populations.

Biology learners describe the metabolic pathways and the transcription and translation of genetic information. They will party on the last page as they trace the flow of information through a large and colorful diagram.

Students perform an experiment involving reverse transcriptase-polymerized chain reaction HIV replication to better examine the biotechnology used by scientists in pharmaceutical research of infections diseases like HIV. Students examine...

Students investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare...

Explore the concept of evolution and cell biology; your class can work in groups to use the internet to view websites on evolution, take a quiz, and complete a lab activity.

AP® free-response questions are often challenging for scholars. Give them practice writing free-response questions using former questions from the AP® Biology exam on topics such as genetic mutations, cellular respiration, evolution, and...

The average AP Biology score dropped in 2018 with the addition of more data tables and graphs. Offer additional practice free-response questions by using the questions from the 2018 AP exam covering phylogenetic trees, cell structure and...

Physical and biological factors affect everyday living. Scholars explore electromagnetic forces, motion, the rock cycle, and geological changes. They examine cells as the building blocks of life and how organisms reproduce using images...

How closely are animals related? Check their phylogenetic trees! The use of DNA sequencing altered our understanding of these relationships. Individuals explore and gain a better understanding of how scientists sort, align, and determine...

Students are introduced to bacteria and their role in biology and finishes with a lab experiment that focuses on antibiotics. They are given an overview of the important concepts involving bacteria and their potential resistance to...

How and why do populations change over time? AP biology aces explore this question by completing this assignment. They write the answers to 21 questions regarding population genetics, stability, genetic drift, polymorphism, and...

Wow! A very detailed slideshow covers complex topics of genome research methods. This is advanced and relevant to the highest level of school biology. Excellent resource if you wish to expose your class to scientific methods and...

In this short space, it would be impossible to describe the breadth of this seven-page genetics worksheet. Geared toward AP or college biology learners, they explore not only the basic vocabulary and concepts, but also the Law of...

Cell division and all the biological aspects of activation and chemical signals are detailed here. Cyclin, G phases, cell growth, and cancer checkpoint control systems are explained and the triggers listed. The slides are very clear and...

Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...

Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

In this viruses and evolution instructional activity, students read an article on line about the avian flu virus and its evolutionary changes. They answer ten questions about the article including topics such as natural...
