1. Characteristics of Living Things
Have you ever wondered what makes something alive? Learn more about the characteristics that classify something as living. These shared traits can be observed in all living things in the world around us.
2. Using Relative Sizes to Measure Animals
Did you know that scientists don't always explain size by using specific values? They can also compare things to show relative sizes, and how the size of new things relates to what you know. In this lesson, we'll learn how to use this technique.
3. Animal Dental Formulas
In this lesson, you're going to learn about various animal dental formulas, what they tell us in terms of the arrangement and types of teeth, as well as what they imply about the animal.
4. Trophic Levels in a Food Chain: Definition & Explanation
This lesson will explore the feeding relationships of organisms in an ecosystem, including food chains and food webs. The lesson will also investigate the different trophic levels of a food chain and give examples of species found at each level.
5. Human Food Chain: Definition & Examples
In this lesson, you will learn what a food chain is and what composes one. You will also learn about different food chains that humans fit into, seeing many different examples.
