In this series of two activities, students explore inherited traits. They use Lab-Aids simulated corn ears and Punnett squares to gather data on, interpret and predict the probability of traits being passed from parent to offspring. They also read about “survival of the fittest,” natural selection, selective breeding and the relationships between these concepts.

Scientific Concepts and Processes

  • Physical differences between parents and offspring can accumulate in successive generations so that descendants are very different from their ancestors
  • Humans can control some characteristics of plants and animals they raise by a process called selective breeding
  • Because of the way traits are passed from parents to offspring, selective breeding for particular traits can result in new varieties of plants and animals
  • “Survival of the fittest” describes how in any particular environment individual organisms with certain traits are more likely than others to survive and have offspring
  • Natural selection describes how different species have, over generations, obtained traits that are well adapted to the environment in which they live
Note: This kit is designed for use with 12 teams of two students. If any of your classes have more students than this kit accommodates, you can obtain extra components. Each Enlarge-A-Lab Kit contains enough materials for two additional student teams.
