People Are Like Peas in a Pod
Students experiment with peapods to show the diversity of individual within a population. They examine dominant traits, recessive traits, genotypes, and phenotypes and show the process of making a Punnett Square.
Curated OER
Edible DNA
Pupils use multicolored soft candies (gumdrops and candy orange slices) and toothpicks to create models of DNA structures. They discuss the fact that DNA must copy itself before splitting into two cells. Students demonstrate this by...
Curated OER
Modeling Mendel's Pea Experiment
Students discover what Mendel uncovered in his famous pea experiments. They form explanations for the result of crossing a true-breeding round pea plant with a true-breeding wrinkled pea plant (the F1 generation) and for the results...

Cellular Transport and the Cell Cycle
With a multitude of questions, this worksheet offers students the opportunity to review their knowledge about the cell cycle. Question types include true/false, word bank, and completing a table about the differences between interphase...
Curated OER
Cloning
In this cloning worksheet, learners fill in the blank with information researched about cloning. Students draw a labeled sketch and complete statements for each step of cloning displayed in the noted text.
Curated OER
Ethics Issues From Science Fiction
Students analyze ethics issues as they read science fiction works. In this science and ethics lesson, students read science fiction short stories of their choosing, investigate the ethics issues raised in the stories, and present...
Curated OER
Should Humans Be Cloned?
Students explore links on the Internet to collect facts about cloning then prepare an essay on their findings. In this research writing lesson students examine how to include their opinions on what they have found in their research.
Curated OER
Extracting DNA from Your Cells - Teacher Preparation Notes
Students extract their own DNA from cheek cells. In this biology instructional activity, students explain the replication process. They identify the structure and composition of DNA.
Curated OER
At a Glance: Genetic Variation
Students conduct a class survey of a variety of human traits and construct histograms of the collected data. They explore how they are alike and different and play a game that introduces the concept of each individual's uniqueness.
Curated OER
Heredity Worksheet #2
For this genetics worksheet, students use a diagram showing the genetic offspring of plants with different types of seeds to answer 4 short answer questions. Then students determine the traits of offspring of different crosses in 1...
Curated OER
Heredity Worksheet: Dihybrid Cross
In this genetics worksheet, students use a Punnett square to determine the genotypes and phenotypes of the offspring of a dihybrid cross. Then students complete 10 fill in the blank questions.
Curated OER
Heredity Worksheet #3
In this heredity activity, students complete two monohybrid crosses and predict the expected outcome of genotypes and phenotypes. They answer five questions about each genetic cross.
Curated OER
The Genetic Basis of Neurological Disorders
Students explore neurological disorders. They examine the presence and absence of discernible genes. Students describe neruological diseases and draw faces of affected persons. They play a human neurology disorders learning game.
Curated OER
Genetic Engineering/Biotechnology
Learners 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
Students 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.
