Curated OER
Sea Urchin Embryology
Learners explore the process of evolution. They examine examples of how homeotic genes may work and obtain gametes. Using a microscope, students observe the fertilization of sea urchins. They video tape the process and write a...
Curated OER
How Does Chance Influence Inheritance?
Students observe how chance affects which genes appear in gametes (Mendel's Law of Segregation). They use beans to represent the recombination of alleles during fertilization.
Curated OER
How Does Chance Influence Inheritance?
Students complete a lab based on how chance affects which genes appear in gametes as in Mendel's Law of Segregation. They review the theories, vocabulary words, and historical background of Gregor Mendel's work with pea plants. They...
Curated OER
Pollen Tube Growth
Learners demonstrate the proper usage of the compound and dissecting microscopes. They identify the parts of a flower and the functions of the flower parts. Students describe the process of gamete formation and fertilization in a flower.
Curated OER
Reproductive Lottery
Students explain that fishes that reproduce externally have to release great numbers of eggs and milt (sperm) in order to ensure fertilization.
Curated OER
Flowers and Pollination
Learners explore the environment by researching plant reproduction. In this pollination lesson, students define botany related vocabulary terms such as disc flower, petal and fertilization. Learners dissect a flower with their classmates...
Curated OER
Pollination Power
Second graders study and examine the structure of a flower. In this pollination lesson plan, 2nd graders observe pollinators in the garden and dissect a flower. Students then plant strawberry plants in the garden and observe the process...
LABScI
Genetic Equilibrium: Human Diversity
Investigate the Hardy-Weinberg Principle to explain genetic equilibrium. The 10th lesson plan of a series of 12 is a laboratory exploration of genetic equilibrium. Your classes use a mixture of beans to model allele and genotype...
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
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
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.
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...
