In this simulation activity, students will collect data, formulate a hypothesis, and run a series of experiments in order to discover the interplay between natural selection and sexual selection in a wild population of guppies.

With this interactive tutorial, students explore the evolutionary adaptation of feathers in birds.

This brief video lesson discusses internal and external plant defenses. Discussion/assessment questions and suggested supplemental resources are also included.

In this unit students will draw conclusions about corals by examining the behavior of hydra; explain and model how corals eat, grow, and reproduce; and explain the difference between hard and soft corals.

In this lab students will examine hydra, a fresh-water relative of coral, under a microscope to observe feeding behavior and identify stinging cells that are characteristic of corals.

In this activity students will explain and model how corals eat, grow, and reproduce. Students will also explain the different types of symbiotic relationships that can exist between coral and the difference between hard and soft coral.

In the Animal Science course, students study large, small, and specialty animals. Students explore the necessary elements--such as diet, genetics, habitat, and behavior--to create humane, ecologically and economically sustainable animal production systems.

Students learn about the amazing evolutionary history of arthropods. The module contains informational text, interactives, and assessments.

Students learn about behavioral and biological animal adaptations, watch a video about the Arctic, and research how specific animals have adapted to this harsh environment.

In this activity, students review a study where researchers tested whether bats change their behavior while hunting based on feedback from echolocation. Students will analyze spectograms and corresponding video snapshots which show the physical and acoustic behaviors of bats as they attempt to capture prey and then answer a series of questions based on the data.

In this unit, students will investigate the adaptations of honeybees and flowering plants to see how each are designed to ensure survival through the pollination process.

Students will work in groups and research their designated terrestrial biome. Students will research abiotic and biotic factors about their biome. Students will create a digital presentation of their biome using Haiku Deck. The presentation will summarize how the abiotic and biotic factors interact in their biome. Students will then use the collected data from the presentations to create food chains and food webs for their designated biomes.

This brief video lesson discusses bioluminescence as an adaptation for survival, hunting, and mating. Discussion/assessment questions and suggested supplemental resources are also included.

Students will make observations of the behaviors of brine shrimp in order to investigate the phenomenon of sexual selection.

In this activity, students evaluate the validity of two different reproductive strategies and their relative advantages and disadvantages.

In this lab, students will learn about the life cycle of corals, including how they grow and reproduce. Students will also consider the chemistry of seawater and demonstrate how calcium carbonate precipitates to form skeletal reef material.

In this lab, students will learn about the life cycle of corals, including how they grow and reproduce. Students will also consider the chemistry of seawater and demonstrate how calcium carbonate precipitates to form skeletal reef material.

Students will describe at least three chemotrophic symbioses known from deep-sea habitats and identify and explain at least three indicators of chemotropic nutrition.

Students design, conduct, and analyze a controlled experiment testing the effects of alcohol on the worm C. elegans.
