In this science worksheet, middle schoolers find the answers to various types of heredity problems. They use the sheet to set goals for completing the unit.

Learners investigate the principles of probability that can be used to predict hereditary traits.

Students analyze genetic characteristics in a given family tree through the F2 generation. Students apply prior knowledge from Gregor Mendel's study with pea plants and his Laws of Heredity to answer questions.

Students extract their own DNA from cheek cells. In this biology instructional activity, students explain the replication process. They identify the structure and composition of DNA.

Find out the science behind ancestry testing! Investigators watch a video exploring how ancestry works before participating in a hands-on group activity. Scholars role play scientists while learning about testing protocols and test...

Students assess some common inherited traits which are easily observable and note their phenotype for the trait. Students compare their phenotypes to those of their parents and attempt to describe the pattern and manor of inheritance.

Students read a story about the life of Russian plant breeder Nikolai I and Vavilov and the national seed bank he established. They research the Irish Potato Famine of the late 1840s and identify the cause for this famine and make...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

Students examine why some freshwater populations of stickleback fish.  In this macroevolution lesson students read a study packet then answer questions. 

For this lesson students create imaginary creatures, called "Reebops," to explore the relationships between genes and inherited traits. Using Reebops as a model, students learn how hereditary information is passed from one generation to...
