Master Genes Control Basic Body Plans
Have you ever been so tired you missed a major announcement? Eric Wieschaus woke to a call explaining he won the Nobel Prize, but he thought it was just a dream until Christiane Nusslein-Volhard, a co-winner, explained it to him later...

Classroom Activities: Stem Cells and Diabetes
How close are we to a cure for diabetes? It seems the cure which has a connection to stem cell research is a possibility! Learners explore the concept of stem cells with an engaging hands-on activity. A PowerPoint presentation provides...
Evidence of Evolution
Since its conception in the mid-1800s, the theory of evolution has been a point of hot discussion, but what exactly do the facts say? Take your life science class on an evolutionary exploration, analyzing the different pieces of evidence...
Stem Cell Differentiation Game Questions
Thirty-five multiple-choice questions are spread out into boxes bordered with dotted lines so that they can be cut out to become game cards. Playing a game to review concepts is an effective way to learn, even if you are in college. Give...
Inside the Egg, Hatching Chickens
Students explore how an egg becomes fertilized. In this biology lesson, students "candle" a variety of eggs in order to determine which ones have been fertilized and which ones haven't. Student use paper plates to create a graphic on the...
Embryology Word Search Puzzle
In this biology word search instructional activity, students search for 36 terms related to embryology. They check off the words as they find them in the puzzle.
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...
Embryology as Evidence of Evolution
Learners 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...
Animal Organs and the Study of Reproduction, Embryology and Cancer
Young scholars examine organs from dogs and cats to study reproduction, embryology, and the identification of cancer. They record their observations at both the gross and microscopic levels. They present their information to the class.
Natural Selection and Evidence Worksheet
Matching and fill-in-the-blank exercises give biology whizzes a chance to practice vocabulary associated with evolution. Terms to be reviewed focus on evidence for evolution, natural selection concepts, and some genetics words. You could...
Evidence of Change
Students identify evidence of change in species using fossils, anatomical similarities, and embryology. They identify homologous structures and arrange the steps of fossil formation. Students complete a group of selection of organisms...
Students compare and contrast the embryonic development of human, chicken and fish embryos. They create a detailed outline of similarities and differences among the three embryos at various stages of development.
Young scholars observe embryogenesis in action through early stages of development of eggs. They observe cultures with dissecting and compound microscopes. They draw their egg, record any details and observe for changes. They compare...
Comparative Embryology Using Japanese Medaka Fish
Students conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.
