The Effects of Alcohol and other Teratogens: A model using Zebrafish
Students investigate the interference of various drugs on an embryo through experimentation. This is an open-ended lab to allow students to see effects of various chemicals humans choose to put in their bodies and create questions they...
Curated OER
Dried Vs. Soaked Beans
Students observe the differences between a dry and soaked bean, and identify the functions and parts of a bean at the beginning of its growth.

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.

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...

Designing a Germination Experiment - Part 1
Students experiment with seeds and germination. In this natural science lesson, students discuss the stages of germination. Students engage in a 4 part hands on science activity to view the process of germination.
Curated OER
How Does Meiosis Lead To a Fetus?
Students discuss the stages of meiosis. In this life science instructional activity, students create an illustration of each stages. They write a short story about a character that went through meiosis.
Curated OER
Life's Greatest Miracle
Students study/identify the effects of maternal consumption of alcohol at various stages of pregnancy. They study how a developing embryo needs a certain environment to evolve into a healthy fetus and healthy baby. They use the...
Curated OER
Ocean Creature Classification
Students develop their own system for classifying a group of objects or organisms using observed similarities and differences. They investigate the process of scientific classification, and explain how marine organisms are classified by...
Curated OER
Ocean Creature Classification
Students develop a Taxonomic Key for marine invertebrates from pictures they are given after practicing together with common objects, such as shoes. They then compare their key to a provided Ocean Invertebrates Taxonomic Key.
Curated OER
Bean There, Done Plant
Students explain that events in nature follow an orderly progression when they plant seeds and observe the development of the seeds. They count seeds and find the likenesses and the differences of many seeds.
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
Embryology as Evidence of Evolution
Students 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...
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...

Reproduction Word Search Puzzle
In this science worksheet, students look for the words that are associated with the theme of the sheet. They also develop spelling and vocabulary.
Curated OER
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...
Curated OER
Homology: Where Does The Evidence Lead
Students are introduced to the topic of homology. In groups, they read a case study and compare different drawings of early vertebrate emryos. They work together to answer discussion questions and label the various parts of each embryo.
Curated OER
Culturing Plants from Embryonic Plant Tissue
Student groups use lima beans to represent dicots and corn to represent monocots, soak the seeds, and separate the embryos from the cotyledons. They then place the seeds in Petri dishes in agar and observe for at least one week recording...
