Genetic Drift
Male northern elephant seals grow to be 13 feet in length and can weigh up to 4,500 pounds. In the video, scholars explore genetic drift in a population through a simulation. The instructor shows allele frequencies changing over time,...
Bozeman Science
Coevolution
Scientists give evolution two opposable thumbs up! In the video, scholars explore coevolution through the analysis of a few different examples. The instructor then explains and shows what coevolution is and is not to eliminate confusion...
Bozeman Science
Abiogenesis
Scholars explore how life on Earth formed more than 3.8 billion years ago through natural processes, from monomers to more complex organisms such as cells and then life. Viewers see the Miller-Urey experiment and how it...
Bozeman Science
Factor-Label Method
One millionth of mouthwash is equal to one micro-SCOPE. This conversion video walks scholars through the factor-label method, or dimensional analysis, step by step. It shows sample problems and builds up to more complex problems, from...
Bozeman Science
What are Chromosomes?
An informative video begins by showing scholars how chromosomes are like encyclopedias. The instructor then explains and differentiates genome, chromosome, sister chromatids, nucleosomes, DNA, genes, and base pairs.

What is DNA?
Who is DNA and why does everyone think she has all the answers? A video instructor explains and shows pupils the structure of DNA and its major parts. Nitrogenous bases, phosphates, backbones, 3 prime and 5 prime, and nucleotides...
Bozeman Science
Transcription and Translation
AAG-CCT-GAA: Can somebody translate this for me? A video demonstrates how transcribing and translating DNA is similar to reading a cookbook to make a meal. Scholars walk through the steps of transcription, converting genes to...
Bozeman Science
Signal Transmission and Gene Expression
Budding scientists learn about signal transmission, exploring intercellular and intracellular chemical movements. The instructor shows how epinephrine signals other chemicals in the body and can cause our DNA to express different...
Bozeman Science
Solving Hardy-Weinberg Problems
What is a gene pool? What do gene pools have to do with the Hardy-Weinberg formula? How was this formula derived? After viewing a video that introduces these concepts, young scientists determine p and q values and then work sample...
Bozeman Science
Phylogenetics
Scholars explore revolutionary relationships among organisms through phylogenetics. Using cladograms, or an evolutionary tree, the narrator shows viewers how organisms are created through morphological (analysis of number of heart...
Bozeman Science
Microevolution
If some genes were exposed to microwaves, would that cause microevolution? In the video, scholars learn about microevolution or any change in the allele frequency of a population. The instructor explains the five ways microevolution...
Bozeman Science
Plate Tectonics
An engaging video explores plate tectonics, from the evidence to support the theory to their movement. The analysis of the location of worldwide earthquakes shows scholars where major tectonic plates meet. The instructor...

X Inactivation
Ever wonder why most calico cats are female? An engaging video explores the inactivation of one of the x-chromosomes in female cats, allowing for calico coloration.
Bozeman Science
Mutations
The majority of cancers, 90-95%, are caused by environmental factors; the remaining 5-10% are due to inherited genes. Scholars explore mutations and their outcomes and see how mutations can occur spontaneously or be induced. The video...
Bozeman Science
Molecular Biology
Explore the bacteria at Yellowstone to introduce molecular biology. Scholars learn about the process of genetic engineering and how it has progressed over time, including the identification of the breast cancer genes and the main...
Bozeman Science
Meselson-Stahl Experiment
One human's entire DNA sequence would take up three gigabytes of storage space. Pupils explore the experiment performed by Meselson-Stahl, which proved DNA copied itself through a semi-conservative process. The instructor explains their...
Bozeman Science
Mendelian Genetics
Young scientists explore Gregor Mendel's work on pea plants, his laws of segregation and independent assortment. They work through genetic problems and then finish by looking at Huntington's disease and genetic testing.
Bozeman Science
Mechanisms that Increase Genetic Variation
Learn how genetic variation occurs within prokaryotes through transformation, transduction, and conjugation. The instructor then explains how sexual reproduction in eukaryotes can lead to crossing over, random assortment, and random...
Bozeman Science
Linked Genes
Scholars analyze Morgan's fruit fly lab to learn how genes are linked. The instructor shows that the data from a dihybrid cross was not what Morgan expected, and when re-crossed numerous times, the data did not change. Viewers see gene...
Bozeman Science
Hardy-Weinberg Punnett Square
Scholars learn how to use a Punnett square analyzing red hair and then apply this process to an entire gene pool over time. The instructor walks viewers through a few problems, determining percentages found within a gene pool.
Bozeman Science
Hardy-Weinberg Equation
Dark, curly, non-red, and thick hair are all dominant genes. The video begins by defining phenotype, genes, alleles, and genotype. Scholars learn how alleles determine genotype, which directs phenotype, using red hair as the example. The...
