38: Living Systems and Processes


3.4: The student will investigate and understand that adaptations allow organisms to satisfy life needs and respond to the environment. Key ideas include

3.4.a: populations may adapt over time;

Natural Selection

You are a bird hunting moths (both dark and light) that live on trees. As you capture the moths most easily visible against the tree surface, the moth populations change, illustrating the effects of natural selection. 5 Minute Preview


Lesson Info

3.4.b: adaptations may be behavioral or physical; and

Comparing Climates (Metric)

Compare average temperatures, precipitation, humidity, and wind speed for a variety of locations across the globe. Explore the influence of latitude, proximity to oceans, elevation, and other factors on climate. Observe how animals and plants are adapted to climate and their environment. This lesson uses metric units. 5 Minute Preview

Comparing Climates (Customary)

Compare average temperatures, precipitation, humidity, and wind speed for a variety of locations across the globe. Explore the influence of latitude, proximity to oceans, elevation, and other factors on climate. Observe how animals and plants are adapted to climate and their environment. This lesson uses U.S. customary units. 5 Minute Preview


Lesson Info

3.4.c: fossils provide evidence about the types of organisms that lived long ago as well as the nature of their environments.

Building Pangaea

In 1915, Alfred Wegener proposed that all of Earth's continents were once joined in an ancient supercontinent he called Pangaea. Wegener's idea of moving continents led to the modern theory of plate tectonics. Create your own version of Pangaea by fitting Earth's landmasses together like puzzle pieces. Use evidence from fossils, rocks, and glaciers to refine your map. 5 Minute Preview

3.5: The student will investigate and understand that aquatic and terrestrial ecosystems support a diversity of organisms. Key ideas include

3.5.b: relationships exist among organisms in an ecosystem.

Forest Ecosystem

Observe and manipulate the populations of four creatures (trees, deer, bears, and mushrooms) in a forest. Investigate the feeding relationships (food web) in the forest. Determine which creatures are producers, consumers, and decomposers. Pictographs and line graphs show changes in populations over time. 5 Minute Preview
