Just because we have the ability to determine an organism's traits through genetic testing, should we do it? Middle-school medical experts examine the ethical dilemmas in biotechnology in the 18th and final installment in a series of...

An eight-unit electronic textbook provides a guide to AP® Biology. Each of the 28 chapters include an introduction, multiple lessons, a summary, review questions, and test prep questions. Teachers see how each lesson connects to a big...

All humans alive today descended from the same woman who lived just 150,000 years ago. A thought-provoking video explains this concept as part of a larger biology playlist. It lists the location where the woman lived as well as where our...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

How did scientists determine the cause of illness before technology? Science scholars play the role of medical researcher in an engaging guided inquiry activity. Using observations, technical reading, and Punnett squares, learners...

Can your class solve the Mystery of the Crooked Cell? Junior geneticists collaborate to learn about sickle cell anemia in a fascinating lesson plan. The included materials help them to examine the genetic factors behind the disease...

Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

In this biology video, the instructor introduces the four main concepts behind Biology approved by The College Board—evolution, free energy, information, and systems. Individuals then listen to and see descriptions and examples of each...

Operons operate on sections of genes. A video begins by explaining that operons are located mainly in bacteria, specifically focusing on lac operon. This lac operon, found in E.coli, breaks down lactose. It then shows how lac operon...

Show learners how to apply genotypes of parents to a Punnett square to determine potential genotypes and phenotypes of offspring with a video that explores monohybrid crosses and then complete a dihybrid cross as well. 

If every human on earth looked exactly the same, the world would be a boring place. Thank goodness for genes! Pupils explore the difference between haploid and diploid cells by learning how two parents without red hair can produce a...

Did you know that your DNA can be damaged tens of thousands of times per day? Learn about the ways that damage to just one strand of your DNA can be fixed, or in extreme examples, result in genetic mutation such as cancer. 

Four different-shaped and dyed pasta types represent four different alleles. Following a guide sheet, young geneticists practice randomly selecting alleles and discover the traits of the resulting offspring. This is a fun and solid...

What is cancer? And why don't we all have it? These concepts are explored and tumor suppressor genes are introduced in this animated feature. This nutshell of information is fully packed and makes an outstanding resource for your biology...

In a sweet simulation, junior geneticists examine the chromosomes of a fictitious Reebop marshmallow animal, combine chromosomes to produce offspring, and then make a model of the resulting Reebop baby. Phenotypes include number of...

Welcome to the complex biological story that is our life. Great visual imagery zooms in on the dissection of a DNA double helix in our body. What happens with RNA? Where do amino acids come in? This resource explores our inner workings...

Biotech engineers discover that changes in the DNA code for cell wall formation can help create crops better suited for biofuel production. They extract DNA from wheat germ. They decode paper strips with codes and relate the activity to...

Junior geneticists tally eye color and height in their lab groups. They examine certain traits in soybean and corn seedlings. For each activity, they gather data and learn about continuous and discontinuous genetic variation. In another...

This exam touches upon every topic within the typical first year biology course.. A broad variety of question styles give high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is...

Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both...

Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

If there are no extenuating environmental factors to ensure competition in a species, then variation is achieved by random mutation. This resource may be more useful after viewers are introduced to the concepts of alleles and the...
