Cell 5 Diffusion and Osmosis
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 bilayer, hydrophilic, and hydrophobic.

Osmosis and Diffusion Lab: Honey I Blew Up the Bear
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 into a clear glass container of hot water for them to observe.

Educate and entertain at the same time! When presenting upcoming biologists with homeostasis in animals, use this colorful and information-packed presentation. Animals make humorous comments on the information provided. It details the processes of water balance and nitrogen waste removal with diagrams, photos, and comprehensive notes.

Gas Exchange And Respiratory Systems.
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 developed. The 29 slides explain diffusion of gases, and students should be able to take useful notes to summarize these facts and processes even further.

Regulating Internal Environment
The many mechanisms of maintaining internal conditions of an organism are detailed here, with clear examples of how separate evolutionary paths have led to different conclusions. The slides are concise and attractively designed with information about diffusion, osmosis, waste diposal, and hormone feedback loops.

Regulating the Internal Environment
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 PowerPoint to show a class that has a basic understanding of system organization in humans.

Biotechnology: Drug Delivery and Diffusion
Students discover advances in biomedical technology such as transdermal delivery and other non-invasive procedures. In lab activities, they examine how medication is given and how molecules travel, observe electrophoresis, and conduct several experiments in groups.

Homeostasis and the Plasma Membrane
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 molecules move during osmosis.

Gas exchange: Respiratory Systems
The need for a respiratory system in humans versus being reliant on gas exchange structures is demonstrated. There are many details about the advantages and disadvantages of each mechanism. Students are able to learn about the hemoglobin (haemoglobin) and oxygen dissociation curve.

Cell Size and Shape; Diffusion and Osmosis Processes
Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to discover osmosis.
