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...
Curated OER
Graham's Law Of Diffusion
Students 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 the...
Curated OER
Gas Exchange
In this biology worksheet, high schoolers examine the process of respiration and specifically look at the biochemistry of gas exchange at the alveoli.

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

Kinetic Molecular Theory
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,...
Curated OER
Diffusion Through Balloons
Students observe the diffusion of air molecules through a balloon. In 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.
Curated OER
It's a Gas!
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...
Curated OER
Matter and Energy
Students 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 the...
Exploratorium
Bubble Suspension
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...
Curated OER
Comparing Solids, Liquids, and Gases
For this solids, liquids and gases worksheet, high schoolers observe a teacher demonstration about gases and they experiment with liquids to show diffusion, shape and volume. They answer nine questions about the experiments related to...
Curated OER
Selling The Molecular Kinetic Theory
Students investigate molecule movement according to the kinetic molecular theory. In this kinetic molecular theory lesson plan, students observe demonstrations showing that molecules speed up with increasing temperature and slow down...
