How Mistakes in Cell Division Can Result in down Syndrome and Miscarriages
Some genetic conditions occur without being inherited. The distinction becomes the focus of the lesson. It details the process of cell division that results in trisomy on various chromosomes. A worksheet highlights the results including...
Curated OER
Meiosis
Students study meiosis and how it leads to variation. In this genetic reproduction lesson students complete a lab activity that calculates different genetic possibilities.
Curated OER
Chromosomes
Students study chromosomes and how molecular half life affects them. For this chromosome lesson students complete several lab activities on calculating half life, and cracking alkanes.
Curated OER
Polytene Chromosomes from Salivary Glands
High schoolers use this laboratory procedure to outline the mechanism by which salivary glands are removed and prepared so that the polytene chromosomes may be observed.Drosophila virilis is used instead of Drosophila melanogaster...
Curated OER
Nature And Nurture
Students develop an understanding of the role both nature and nurture play in determining an individual's traits. Using a website, students answer questions about nature and nurture in order to solve the riddle, What do you call a smart...
Curated OER
Biology Word Search Puzzle
In this biology word search worksheet, students search for 29 words that are located in a word bank at the bottom of the page. They find words such as chromosomes, alleles, DNA, and populations.
Curated OER
DNA
In this science worksheet, students read about cells, chromosomes, and genes. Students order the following items from largest to smallest: cells, chromosomes, DNA, genes, and bases.
Biology Junction
Cell Cycle and Mitosis
Deepen understanding of cell division with this resource. Young scientists read short paragraphs about the different stages of the cell cycle and use this information to answer a series of basic short answer questions and label several...
Curated OER
AP: Chapter 14: Mendel and the Gene Idea
A survey of Mendelian genetics is presented through this handout. Biology prodigies answer questions about the Law of Segregation, phenotypic ratios, and dominance. They define genetics vocabulary terms and describe various genetic...
Curated OER
AP: Chapter 16: The Molecular Basis of Inheritance
Advanced biology masters take a close look at DNA and the scientists who contributed to our understanding of this complex and powerful molecule. They answer 21 questions about DNA structure, replication, and repair. This can be used as a...
Curated OER
Chromosome Fusion
Students see how patterns can reveal events of the past, thereby merging elements of both experimental and historical science.
Biology Junction
Nucleic Acids
In this DNA instructional activity, students identify the different parts of the DNA and color them. They complete 16 short answer and fill in the blank questions on DNA.
Curated OER
Mutations and Genetic Change
In this genetic mutations worksheet, students compare and contrast different types of mutations including point mutations, silent mutations, and frameshift mutations. This worksheet has 5 matching, 4 fill in the blank, and 3 short answer...
Curated OER
Fertilization to Birth
In this fertilization instructional activity, students complete 10 short answer questions about the phases of fertilization then place 6 events of fertilization in the appropriate order on a timeline.
Curated OER
When Heredity Follows Different Rules
In this heredity learning exercise, high schoolers will use a Punnett square showing the mating of a human male and female to answer 4 questions. 2 short answer questions, 2 true or false statements.
Curated OER
An Inventory of My Traits
In this biology activity, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not...
