In this lesson, students will examine the form and function of anatomical features of the horseshoe crab that allow them to survive in the estuary environment.
In this activity, students use observation to explore earthworm anatomy and the nature of science.
In this activity, students will use the skill of scientific sketching to better observe and document the natural world. This simple-to-lead activity gets them closer to constructing explanations for the variation of traits seen within a species.
Students conduct a series of experiments to test how the physical characteristics of penguins help them to swim and dive.
This lesson focuses on students understanding how organisms' specialized structures and variations work with the environment to help them survive. Students will create a life form to populate one of the landforms on the planet Wakyabi. Thye must add three specialized structures to their organism in order to ensure its survival.

In this video, students learn that, through adaptation, organisms develop certain features that aid their survival. They pass these on to future generations through the process of natural selection.
This lesson helps students recognize that living things can change over may generations and the importance of variation within a population of animals. Students will be introduced to natural selection as a mechanism of evolutinary change.

In this lesson, students will study two animals to understand how their variations give each a survival advantage.
In this interactive game, students make decisions to change the characteristics of a dinosaur so that it can better adapt and survive in changing environments.
Students will compare and contrast related organisms and discover their survival advatage. Students will examine photos of two related organisms and list physical characteristics that are similar and unique among the organisms. After a class discussion on how variations give organisms a survival advantage in their environments, students will participate in shared writing assignments.
Students learn about habitats, and why and how animals and plants are best suited to particular habitats.
In this lesson, students understand that some animals have features that make them harder to find in their surroundings and help them to survive in their habitat.
