Curated OER
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...
Curated OER
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
Comparative Embryology
High schoolers 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.
Curated OER
Incubation and Embryology
Students examine chickens, eggs and hatching eggs through this series of lessons.
Curated OER
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.
Curated OER
Inside the Egg, Hatching Chickens
Students conduct an egg candling activity to show the life inside a fertile egg. Students discuss the needs the egg has of the hen, as well as similarities and differences between plants and animals. Students complete a life cycle wheel...
Curated OER
The Effects of "Recreational" Drugs on the Development of Chick Embryos as a Model for Human Embryogenesis
Young scholars conduct experiments on fertilized chicken embryos to determine the possible developmental effects that various recreational drugs (caffeine, alcohol, nicotine, and aspirin) might have on them.
Curated OER
Natural Selection
Students estimate how many different species of organisms inhabit the Earth. In groups, they match the pictures of embryos at the different stages of development. They compare and contrast animals from the sky, land, and water and...
Curated OER
How Fragile Is an Egg?
Learners design a "container" for his/her egg to determine whether the egg remain intact when dropped from a predetermined height.
