Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions-including energy, matter, and information flows-within and between systems at different scales. Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. This lesson focuses on the following Three Dimensional Learning aspects of NGSS:ĭevelop and use a model based on evidence to illustrate the relationships between systems or between components of a system.Īlignment agreement: Thanks for your feedback! Define osmosis, diffusion and semi-permeable membranes and understand how organisms use them.ĭevelop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.Ĭlick to view other curriculum aligned to this Performance Expectation.Construct and identify cell membrane parts.Describe how organisms use physical phenomena to actively transport nutrients.Identify organelles in a cell and their function.Studying the cell membrane's structure and function provides the details engineers need if they are to facilitate the ease of entrance.Īfter this lesson, students should be able to: In order for students to understand what is happening inside cells, they must understand how particles gain entrance to cells. With the evolution of nanoparticle use for drug delivery and many other applications, the cell has become a main focal point of research, making intracellular engineering a specialized area of biomedical engineering. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).

Lastly, students use the associated activity to test their understanding of the cell structure and membrane. Then they observe three teacher demonstrations that illustrate diffusion and osmosis concepts, as well as the effect of movement through a semi-permeable membrane using Lugol's solution. They view online animations of cell membrane dynamics (links provided). Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle.
