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. Students discuss diffusion which is an example of passive transport.
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. The accompanying activity involves individuals soaking a bear-shaped gummy candy in distilled water overnight, comparing before and after measurements of mass and length. This resource would support your life science lesson on passive transport.
Learners distinguish between diffusion and osmosis and describe ways that drugs can be administered.  In this diffusion lesson students research career paths and create a presentation to give to the class. 
In this biology learning exercise, students examine the effect of electrolytes upon the homeostasis of the body. They focus upon how the body regulates the ph level.
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. 
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.  
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. Some slides have questions regarding the mechanisms of regulation which stimulate questioning and discussion from the students.
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.  
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. In another activity, students inspect how drugs are delivered through a stent and how catheters and angioplasty balloons are inserted.
In this biology activity, students review in depth curriculum content concerning the human body and the effects of external factors while considering internal functions.
In this homeostasis activity, 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.
For this biology worksheet, students review in depth curriculum content concerning the human body and the effects of external factors while considering internal functions.
For 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. Then, students identify which substance moves in osmosis.
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.
Students conduct various experiments on glucose. In this biology instructional activity, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
Students investigate the structure and function of the excretory system of the human body. Breathing, sweating, and urinating are explored as important components of the system.
Students design a scientific investigation to test a hypothesis and evaluate the designs of sample investigations.  In this investigative lesson plan students organize and interpret data and evaluate results. 
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. 
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. Six activities in all, this collection is a must for your biology class! Lesson plans are thoroughly written and the activities are both engaging and informational. Thank the National Science Teachers Association for this gem of a resource!
In this biology learning exercise, high schoolers examine the relationship between acids and bases and how they are related to one another. They focus upon how the body regulates the ph level.
