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...

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...

In this gas laws worksheet, students use textbooks and dictionaries to find the definitions of 20 terms associated with the gas laws.

High schoolers demonstrate Graham's Law by observing a gaseous diffusion. After a lecture/demo, students perform an experiment then complete a write up activity which is imbedded in this plan to reinforce what they have observed during...

For this biology worksheet, high schoolers examine the process of respiration and specifically look at the biochemistry of gas exchange at the alveoli.

Students are challenged to come up with a good estimate of the amount of air in foamed polystyrene products. They use this gas evolution experiment and as such have students measure the gas generated when foamed polystyrene is degassed...

Students conduct a series of experiments to explore Graham's law. In this chemistry instructional activity, students differentiate effusion and diffusion. They perform calculations using Boyle's, Henry's, Charles' and Graham's Laws.

Topping this activity is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these notes,...

A slideshow that covers the all-important details related to basic human circulation. The reasoning for exchange of material methods is presented and then labeled diagrams of the main human transfer systems are shown, along with...

In this gases activity, students solve twenty problems using the gas laws and their understanding of the relationship between energy and temperature and energy and velocity.

Students investigate gases and their properties by completing 4 activities. In this gases lesson plan, students perform activities to show that gases take up space, they diffuse, and that odors and vibrations pass through gases. They...

Young scholars observe the diffusion of air molecules through a balloon. For this chemistry and molecules lesson, students fill balloons with air and a scented substance and observe whether the scented air is able to permeate the balloon.

In this biology worksheet, students examine the transport of gases in the circulatory system and how they bond to hemoglobin.

In this gases worksheet, students review the kinetic molecular theory and use the ideal gas law to solve 20 problems.

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

In this states of matter worksheet, students are given a summary of the particle arrangement, the motion of particles, the properties of particles, and models of particles in solids, liquids, and gases. Melting, evaporating, boiling,...

Although it contains some formatting issues, the Word document here contains good questions about osmosis and diffusion, and is easy to edit as needed. Designed as a study guide, you could use the information here for warmups, ideas for...

In this gas laws worksheet, students apply Graham's Law by completing 6 problems finding the velocity and molecular mass of gases.

Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity: Carbon dioxide gas is more dense than air Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

Organelles, cellular respiration, ATP, and DNA. The passage attached to this life science reading comprehension worksheet is all about cells. After reading about diffusion and osmosis, kids answer a series of questions based on the text.

Middle schoolers participate in a small group read aloud of the short story, "Cerium" by Primo Levi. They answer several questions about the story and then relate the reading to a lecture on Kinetic theory. After the lecture they apply...

For this gas law worksheet, students learn how Graham's law governs the diffusion of gases. Students calculate the velocity and effusion rate of gases at certain temperatures. This worksheet has 6 problems to solve.

For this respiratory system: breathing worksheet, students read through the given notes. Students then compare the different respiratory systems with that of an earthworm, fish, insect, and frog.

Sixth in a series of 36, this lesson focuses on gases and their behavior in given situations. Learners review the states of matter and then focus on gases, specifically learning Boyle's, Charles's, Avogadro's Laws, Dalton's, and Graham's...
