Genetic Engineering/Biotechnology
Pupils create a paper model of a plasmid and insert a DNA molecule that contains a specific gene into the plasmid. They complete an actual transformation involving E. coli bacterium and relate the two activities to one another.
Curated OER
Gene Puzzles
Learners explain that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. They examine a fictional pedigree and determine which gene is responsible for a given trait.
Curated OER
Genetics: Genes and DNA
Students study DeoxyriboNucleic Acid or commonly known as DNA and discover importance of DNA strand, chromosomes, and genes.
Curated OER
Hardy-Weinberg Equilibrium According to Hoyle: OR, Population Genetics or Platypapyrus foursuitii
Students use this exercise to help achieve a working knowledge of the Hardy-Weinberg Equilibrium without recourse to algebra. After participating in this activity, students gain a feeling for the significance of the Hardy-Weinberg...
Curated OER
DNA and Genetic Expression
Students, in groups, complete a worksheet on DNA transcription and translation. They determine codons for particular amino acids. They attempt to introduce mutations to determine what will happen to the DNA sequence.
Curated OER
Reproduction and Heredity
Sixth graders investigate how traits are passed from parents to their offspring. They list things they have in common with family members, read key vocabulary terms, create a poster of shared physical and personality traits, and watch...
Curated OER
Punnett Squares
Fifth graders examine how traits are passed to their offspring using Punnett Squares. They demonstrate how a Punnett Square works by physically moving around boxes taped on the floor, representing the different traits of chicks and...
Curated OER
Stack #84201 Word Search
In this science worksheet, students locate and identify various vocabulary terms related to biology. There are fifteen words located in the puzzle to find.
Curated OER
RNA and Gene Expression
In this RNA and gene expression worksheet, students match the letter of the description that best matches the term as it relates to gene expression. Students also answer questions as it relates to the process of transcription and...
Curated OER
Alcohol and Driving: When to Say No
Students inspect the factors involved in blood alcohol concentration. They observe a Web-based driving simulation and discover the physical and mental impairments caused by alcohol. They calculate the blood alcohol content in various...
Curated OER
Artificial selection
Young scholars brainstorm a list of improvements they might make to a picture of a skinny cow to improve its milk yield. They draw ideas on the board and compare these pictures with the original and ask the students which cow they would...
Curated OER
Gametogenesis and Fertilization
Students explore how this module focuses on part of the cycle of alternation of generations: meiosis to produce haploid spores and fertilization to produce a diploid zygote which grows into the adult plant.
Curated OER
Heredity, Genetics, Traits
Eighth graders study how an embryo develops into a fetus by undergoing many physical changes which they observe on a poster. They examine the metamorphosis of fruit flies as they develop through a series of changes. They record the...
