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...
Curated OER
The Cell Cycle and Cancer
Students compare and contrast the cell cycle of frog eggs, normal cells, and cancer cells. They watch a video about early development of the frog embryo, generate a hypothesis in small groups, and listen to a teacher-led lecture. ...

Parts of the Seed
In this biology worksheet, students read about the parts of plant seeds and look at a seed diagram. They read about the roots, endosperm, embryo, and the process of germination. They answer 8 online multiple choice questions based on the...
Curated OER
Fertilization to Birth
In this fertilization instructional activity, middle schoolers complete 10 short answer questions about the phases of fertilization then place 6 events of fertilization in the appropriate order on a timeline.
Curated OER
The Energy of Life in Zebrafish
Students study the stages of development of an unknown organism. In this zebrafish lesson, students examine and collect data as they use microscopes to view a zebrafish embryo.
Curated OER
A Model of Morphogenesis in Drosophila Melanogaster
Students investigate the following scientific terms and ideas: rates of diffusion, the role of morphogens in the development of larva, the chemical dynamics of a cell, and the significance of embryo polarity during development.
Curated OER
Elegant Embryology
Students 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 their...
Curated OER
How To Make an Artificial Organ
Students examine the advances made in technology with regard to prosthetics and replacement organs and limbs. They describe the anatomy and functions of different organs and create their own artificial organ. They defend and present...

Discovering Mitosis in Onion Roots
High schoolers discover the different stages of mitosis by examining onion roots under a microscope, drawing diagrams of what they see, and organizing collected data in a chart and create a pie graph from their lab data.
Curated OER
Ready for Roots
Fourth graders sort seeds and predict what conditions are needed for them to germinate. They keep the seeds moist, observe and measure their growth and graph the results. As the seeds start to grow students compare and contrast the each...
Curated OER
Reproduction and Development
In this development worksheet, students compare the characteristics of mitosis and meiosis. Students review the male and female reproductive organs and their functions. This worksheet has 4 graphic organizer, 6 short answer, and 16 fill...
