Plant Structure and Function: Roots, Stems, and Leaves
Scientists found fossils of plants more than 420 million years old—but plants existed for up to 100 million years prior to these fossils. Learn about the importance of plants to the entire planet. Viewing a presentation helps scholars...

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
Pollination Power
Students go out into the garden and observe pollinating animals through hand lenses. In this pollination lesson plan, students also discuss how animals carry seeds to create new plants elsewhere.

Seed Plants: Gymnosperms and Angiosperms
One of the reasons plants found success on land relates to seed development. Scholars learn about many different forms of seeds and how they changed over time. It describes the structure and function of many different types of seeds in...
Curated OER
Genetics Worksheet
In this genetics worksheet, students answer a variety of questions about genotypes, phenotypes, genetic inheritance, and traits. They solve for the probability of genotypes and phenotypes of offspring by completing monohybrid and...
Curated OER
Applying the Laws of Inheritance
Biology and mathematics can be integrated through a study of Mendelian Genetics.
Curated OER
Yeast: A Dihybrid Cross
Students create a yeast dihybrid cross and follow two forms of each of two traits: red growth versus cream color, and tryptophan-dependent versus tryptophan-independent. They complete diagrams to represent the alleles, predict the...
Curated OER
How Do Flowering Plants Reproduce
Students investigate how flowering plants reproduce. They identify and describe the functions of the major sexual organs of a flower and fruit by examining and dissecting flowers and fruit.
Curated OER
How Do Organisms Reproduce
Students examine the difference between mitosis and meiosis, and describe the steps involved in meiosis and the significance of each step. They create a diploid nucleus containing two pairs of chromosomes using clay.
Curated OER
Punnett Squares/Genetics
Ninth graders complete a monohybrid cross and a dihybrid cross. In this biology lesson, 9th graders predict the traits of offspring using the Punnett square. They differentiate recessive and dominant genes.
Curated OER
Biology Honors Final Project
Tenth graders work on a project about cellular biology and genetics. In this biology lesson, 10th graders research about the assigned human body system and genetic disorders that affect it. They create a multimedia presentation and...
Curated OER
Plants
In this plants instructional activity, students review the alternation of generations in plants and the function of seeds and flowers for plants. This instructional activity has 11 short answer questions and 4 fill in the blank questions.
Curated OER
Pollen & Pollination
Students identify the different ways things are pollinated and how to manage pollen. In this pollination lesson students complete an experiment on how moths pollinate flowers.
Curated OER
Yeast - A Dihybrid Cross
Students make a yeast dihybrid cross and follow two forms of each of two traits: red growth versus cream color, and tryptophan-dependent versus tryptophan-independent.
Curated OER
Dragon Genetics Lab-Principles of Mendelian Genetics
Students study genetic traits using popsicle sticks as chromosomes. In this biology instructional activity, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.

Balancing Chemical Reactions 2
In this balancing chemical reactions worksheet, high schoolers balance equations, identify electrons gained or lost in atoms and identify the number of atoms of each element for the reactants and products in equations. They also answer 3...
Curated OER
Apoptosis: Programmed Cell Death During Development
Students model the plasticity of neural pathways for memory in the brain. They simulate the cell activity according to dots on cards that they are given. They complete various simulations of different cell combinations.

More on Meiosis
In this meiosis worksheet, students fill in the blank that describes the process of meiosis. Students also draw the process of meiosis.
Curated OER
Allele Frequencies and Sickle Cell Anemia Lab
Pupils investigate how selective forces like food, predation and diseases affect evolution. In this genetics lesson, students use red and white beans to simulate the effect of malaria on allele frequencies. They analyze data collected...
