Where It Comes From: All About Heredity
Characteristics are not only inherited, but can be acquired through interactions with the environment.
Chicago Botanic Garden
Migration, Adaptation, and Changing Climates
It is easy for humans to adapt to changing environments, but how do animals and plants do it? Classes discuss how plants and animals deal with environmental changes in the second of seven lessons. Through questions and discussions,...
Curated OER
Introduction To Floral Morphology
Students create a model of the four basic whorls of flowers using a water bottle, construction paper and Q-tips. They then examine fresh flower specimens to see how the basic structure can vary in different species of flowering plants.
Curated OER
Pea Plants Dihybrid Cross
In this dihybrid cross learning exercise, students are given four crosses to complete using punnett squares. They determine the genotypic and phenotypic ratios of the offspring.
Curated OER
Perplexing Polka Dots
Tell case study story of EMS-induced chlorophyll polka-dots in C-ferns. You will need to be familiar with the experiment, as there are some slides that have only photos, no text and no presenter's notes. By using this presentation,...
Curated OER
Mendellian Genetics
Students describe the inheritance patterns other than simple dominance. They are taught how Mendel's principles apply to all organisms. Students review the use of Punnett Squares. They are taught the principles of probability and...
Curated OER
When Heredity Follows Different Rules
In this heredity worksheet, students will create 3 Punnett squares to determine the genotype and phenotype of the offspring from specific breedings. Then students will answer 7 true or false questions based on chromosomes and sex-linked...
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
Genetics
Students explain the difference between dominant and recessive genes, identify what causes differences in the traits of parents and their offspring, and explain how sex is determined. They will also improve their reading and...
Curated OER
Asexual Reproduction
Sixth graders investigate how asexual reproduction produces single-parent offspring. They use plants and yeast to demonstrate vegetative propagation and budding in a laboratory. Students draw five different types of asexual reproduction.
Curated OER
Specialized Structures and Environment
Fifth graders read about how different animals protect themselves, and how characteristics give animals an advantage in their environment. Students then discuss a variety of "outer" wear for humans, and what they might choose to wear in...
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
Chalkboard Challenge
In this PowerPoint, students compete in a quiz show game similar to Jeopardy in which they generate questions to match science facts in a number of categories. Science concepts covered include plants, animals, and matter. Due to the vast...
Curated OER
Bringing the Rain to Kapiti Plain
Learners identify the African Plains and the plants and animals that are found on the plain, which are of a benefit to humans. They listen to the story and actively participate in a choral reading of Bringing the Rain to Kapiti Plain.
Curated OER
Critters in Your Own Backyard
Pupils identify various animals and their habitats, as well as their specific traits In this animal habitat lesson, students list animals they've seen in their backyard. Pupils select one animal and do research. Students then answer 9...
Curated OER
A Look Into the Past
Students practice looking at their genetics to inquire about their past. In groups, they determine their recessive and dominant genes and plot their height on a graph. They compare and contrast the processes of meiosis and mitosis. ...
Curated OER
Living Corn Necklace
Fifth graders explore heredity and observable traits through experimentation. They view several different types of corn and record their observation of physical traits on a class chart. They create a corn necklace by sprouting dried...
Curated OER
How Do Organisms Vary?
Students study variation of organisms. They determine this variation arises from genetic and environmental causes.
Curated OER
Diversity and Adaptations of Organisms
Eighth graders discover how animals adapt to their surroundings. They identify physical traits and behaviors that are important to survival. They examine the results of an organism's failure to adapt.

Sounds of Selection
Do you want a creative and fun way to teach about natural selection? Hop to it by turning your middle school princes and princesses into frogs trying to catch as many bugs as possible in a Hungry Hungry Hippos style game. For high...
Agriculture in the Classroom
A Rafter of Turkeys
How did that turkey get from the early Aztec culture to your table? Learn about the history of wild and domesticated turkeys in North America, as well as their inclusion in Thanksgiving traditions, with a two-part agricultural science...
Curated OER
Brays Bayou Spiderwort Genetic Study
Students formulate hypothesis based upon data gathered by examining possible crosses of spiderworts using Punnett squares. They present explanations for physiological adaptations of spiderworts that resulted from interactions within the...
Curated OER
Genetics and the Work of Mendel
Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images...
Western Kentucky University
Understanding Genetics: Punnett Squares
Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...
