Karyotypes and Inheritance of Chromosomes
Students explore the mode of inheritance of chromosomes. Given a scenario, students use the Human Genome sheet to determine inherited chromosomes. They illustrate the difference between genotype and phenotype. Students develop a model...

Life Cycle of the Drosophila Fly
Students observe the life cycle of the Drosophila fly as well as manipulate large numbers of flies, determine the difference between the sexes, and identify the different stages of the fly's life cycle.
Curated OER
Development Before Birth
In this development activity, students review the process of fertilization in placental organisms. Students determine what trimester certain events take place in a fetus' development. This activity has 10 fill in the blank and 7 matching...
Curated OER
Continuing Life
In this reproduction worksheet, students will review the genetic processes in sexual reproduction and asexual reproduction by answering 6 true or false statements. Then students will complete 2 short answer questions about the offspring...
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
Curated OER
Create-A-Kid
Students flip a pair of coins to determine what genotype and what phenotype their child have for 29 given traits. They draw a picture of their kid based on their coin flip phenotypes.

Winogradsky Columns: Microbial Ecology in the Classroom
Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....
Curated OER
What Is Cloning?
Students differentiate between reproductive and therapeutic cloning and then use research, discussion, and writing in journals to examine their own personal opinions on these subjects.
Curated OER
Where Are the Dinosaurs?
Students explore the concept of extinction by studying dinosaurs. In this dinosaur lesson, students distinguish between extinct creatures and those that still exist.
Curated OER
Karyotype Puzzle
Young scholars identify chromosome pairs based upon band patterns and location of centromere. They order chromosome pairs based upon size. Students differentiate normal karyotypes from abnormal karyotypes. They correctly record karyotype...
