In this lesson, students discover phenomena surrounding how frogs have different internal and external structures throughout their life cycle that enable them to survive in their environments. This page highlights components of this lesson.  ](https://www.knowatom.com/science-phenomena-videos/4th-grade-science/frog-life-cycle) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/4th-grade-science/frog-life-cycle) [![](https://www.knowatom.com/hubfs/image2-Oct-07-2023-03-20-03-7546-PM.png) ](https://www.knowatom.com/science-phenomena-videos/4th-grade-science/plant-structures) ## [Plant Structures In this unit, students analyze how living things have specific structures that allow them to function in different environments. They trace how energy flows through a tropical wetland food web, and then test how temperature affects a plant’s ability to transpire through its leaves, affecting its ability to grow.

This lesson has students observing the patterns caused by the changes an organism goes through as it moves through its life cycle. This page is a high-level extract from the first lesson in this unit.](https://www.knowatom.com/science-phenomena-videos/3rd-grade-science/life-cycles) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/3rd-grade-science/life-cycles) [![](https://www.knowatom.com/hubfs/image4-Oct-08-2023-12-34-51-8368-PM.png) ](https://www.knowatom.com/science-phenomena-videos/5th-grade-science/plant-growth-and-acid-rain) ## [Plant Growth and Acid Rain In this unit, students focus on how environmental changes impact the ability of organisms to survive, grow, and reproduce, passing their traits on to future generations. In this lesson, students continue their analysis of how a plant’s structures allow it to grow and develop, focusing on how a change in the environment such as pollution can impact a plant’s ability to complete its life cycle. Specifically, students investigate how acid rain affects the external structures of aquatic plants.

In this lesson, students explore how a change to the kind of plants in an environment results in a ripple effect phenomena on predation in the area.
