Curated OER
Who's the Father?
Students analyze gels to determine parentage in this lesson about scientific evidence, investigation, and DNA concepts. The lesson includes a pre-activity worksheet, a final individual assessment, and student handouts for in-class...
Curated OER
The Genetics of Parenthood
Learners explore the field of genetics. Through a graphing activity, students assess four common traits. They complete a Meiosis I and II charts which represent possible gametes for an individual. Learners discuss phenotype and...
Curated OER
Thumb Measurement
Learners practice measuring using the metric system and millimeters. They measure their thumbs and record their findings. Students record the findings of their classmates and find the average or mean for the two groups.
Curated OER
If Your Mom Has Big Feet, Will You Have Them Too?
Students describe and apply the Mendellian principles of genetics, focusing predominantly on dominant and recessive genes. They demonstrate how two parents contribute genes and how those genes appear in their offspring. They describe...
Curated OER
Punnett Squares
Pupils revie the Law of Independent Assortment and Law of Dominance. They practice Punnet squares and predicting genetic outcomes and identify factors that influence heredity.
Curated OER
Blood Business
Students identify the different kinds of blood. In this biology lesson, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.
Curated OER
Genetics: Punnett Squares
Students examine Punnett squares charts and analyze how they are used for successful breeding and predictions of certain traits. They complete interactive Punnett square charts, quizzes, problems, and concentration games.
Curated OER
Drosophila Melanogaster
Students cross wild type flies and mutants, both purchased from a biological supply house (Carolina Biological Supply or Wards, for example) in groups from lesson plan one.
Curated OER
Inheritance Intrigue
Students slve a case of unclear heredity using three lines of evidence and knowledge gained from the instructional activity in this biology instructional activity about Mendelian inheritance. The instructional activity includes handouts...
Curated OER
Camouflage and Protective Coloration: A Model of Natural Selection
Students collect data and compare whether protective coloration or camouflage provides better biological fitness in a given environment. They simulate predator prey interactions of two different species and use gene frequencies to...
Curated OER
Molecular Approaches to Evolution
Students are introduced to working with molecular data. The first activity does both simulated and original data are used to compare amino acid, protein or DNA differences to construct phylogenetic trees or cladograms. These activities...
Curated OER
What Do Genes Look Like?
Seventh graders describe the basic structure of the DNA molecule. They identify what an inherited trait is and how it can be determined by one or more genes. Finally, 7th graders identify that plant and animal cells contain several...
Curated OER
Biology Honors Final Project
Tenth graders work on a project about cellular biology and genetics. In this biology instructional activity, 10th graders research about the assigned human body system and genetic disorders that affect it. They create a multimedia...
Curated OER
Cell Reproduction and Inheritance
Students determine their inherited characteristics from their parents. In this biology lesson, students study the life of Mendel using an interactive website. They differentiate dominant and recessive characteristics.
