Diffusion Teacher Resources

Beginning biologists explore passive transport through two demonstrations and a hands-on inquiry. Spray air freshener from one spot in the classroom and have class members raise their hands as the scent reaches them. Also, place a teabag...

No, it really is okay to play with your food! Emerging scientists manipulate popcorn, eggs, and other household objects as they demonstrate multiple cellular processes. The activity, capable of modifications, is designed to reflect...

Explore structures within the realm of gas exchange in terrestrial and aquatic life.  The excellent, labelled diagrams and clear descriptions help your students view the different structures and adaptations that have...

Students distinguish between active and passive transport. Students identify key words associated with active and passive transport. They draw and explain the structure f the cellular membrane. They are able to define phospholipid...

Lead your high school class on an exploration inside the cell. Individuals investigate the relationships between cells structure and function given their relative locations on the cell membrane. They explore the concept of homeostasis...

This presentation begins with the many problems multicellular organisms which rely on diffusion encounter. There are many diagrams of mammalian organ structures, and they are labelled with their relevant functions. This an excellent...

In this homeostasis and plasma membrane worksheet, students complete 4 different questions related to the diagram shown at the top of the sheet. They draw an arrow across the plasma membrane in the diagram to show which way water...

In this homeostasis worksheet, students complete a crossword puzzle with 22 question on homeostasis and cell transport. They identify the different ways substances are transported in and out of the cell.

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year course on the living...

Tne New York Regents High School Examinations are comprehensive and include various styles of questions, includingmultiple choice and the analysis of graphs. This particular version, the 2008 Living Environment exam surveys a variety of...

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple choice, graph interpretation, and essay analysys questions, 73 of them in all. Topics range from...

The 2005 version of the Regents High School Examination in the area of ecology is as comprehensive as previous years' exams. It consists of 40 multiple choice questions on everything from the structure of DNA to the interactions within...

The living environment, from the interior of a cell to the complex relationships among populations, are queried in this final examination. Learners look at air pollution maps, diagrams of cells, population graphs, and drawing of cells....

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

In this homeostasis and plasma membrane worksheet, 9th graders identify and solve 11 different vocabulary terms and definitions. They review the definitions of the words listed and then use the clues to complete the puzzle shown....

Tenth graders develop a hypothesis and explain what they observed on an activity.  In this investigative lesson students observe osmosis and report their data using a graph. 

Cells are busy places! How do things move around in such a tiny environment? Introduce young life scientists to the types of cellular transport through a video that is part of a large biology playlist. Animated characters demonstrate how...

New research proves even rinsing your mouth with carbohydrates without swallowing improves performance of the central nervous system. While some think sports drinks are amazing, others say they are a waste of money. Scholars learn about...

In this biology worksheet, students identify and locate various vocabulary terms related to cells of the body. There are 31 biology terms located in the word search.

Have you ever wondered how important gases enter and leave cells? Take an up close tour of a pore in a cell membrane. Then explore diffusion, osmosis, and active transport through this collection of interactive models.

A complete, self-paced lesson on homeostasis in the human body, focusing on kidney function. Students work their way through illustrated and animated tutorials, and answer review questions along the way. There is a self-checking quiz at...

This comprehensive study guide covers the main terms and concepts needed for a unit on cell transport and homeostasis.

[Free Registration/Login may be required to access all resource tools.] This tutorial serves as an introduction to active transport and explains how to distinguish active transport from facilitated diffusion.
