Nonvascular and Simple Vascular Plants: Mosses to Ferns
Sometimes conservationists use specific plants to prevent erosion or fight invasive species. A 50-slide presentation covers both nonvascular and vascular plants. It discusses the plants, their stages and life cycles, reproduction, uses,...

Dragon Genetics - Understanding Inheritance
Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...
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...

Human Cloning: Is it Biological Plagiarism?
Is cloning good or harmful? Help your class understand the risks and benefits as they read, research, and discuss human cloning. Individuals form teams, research information, and present to the class before concluding with an in-depth...

Cnidarians
In this cnidarians worksheet, students will read 4 descriptions and identify each as either the polyp or medusa form of cnidarian. Then students will complete 3 short answer questions about the characteristics of cnidarians. Finally,...

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...

Invertebrate Phyla
Students explore the invertebrate phyla. They discuss the characteristics of the invertebrate Phyla in the Kingdom Animal. Students classify organisms into Phyla based on their characteristics. They distinguish radial symmetry, bilateral...

Flowers and Their Life Cycles
First-time florists will be able to label the structures of simple and composite flowers after reading this handout and answering the comprehension questions. There are a couple of grammatical errors in the text, but the content is...

Embryology as Evidence of Evolution
Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

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...

Human Embryology
Ninth graders are introduced to the concept of human embryology. Individually, they complete an exercise in which they determine which trait they got from which family member. In groups, they identify and label the reproductive organs...
Curated OER
Patterns of Heredity
Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...
Curated OER
Biology-Genetics
Students predict the probable mode of inheritance from a pedigree diagram showing phenotypes. They study the genetic basis for Mendel's laws of segregation and independent assortment. They give a Power Point slide show demonstrating the...
