Pollution and Lung Health
Learners investigate how pollution affects lung health. For this pollution and lung health lesson, students build lung models from a soda bottle and balloons, and then discuss how the emissions from fossil fuels can adversely affect lung...
Baylor College
Lungometer
Life science learners construct lung-o-meters from gallon-sized milk jugs and then measure their lung capacities. For older young scholars, have them graph the vital lung capacities of each person in the class. Cross-curricular pieces...

A Close Encounter of the Tree Kind
Learners study trees in their natural habitat. In this tree activity, students complete a number of outdoor activities to estimate the height of a tree, examine how bark can be a distinguishing tree characteristic, and how to make a bark...
Curated OER
Yeast
Students study the characteristics of yeasts. In this biology lesson, students conduct experiments to measure yeast respiration. They discuss the favorable conditions needed for growing them.
Curated OER
Microbial Influence on Earth's Systems
Learners identify the different biogeochemical cycles on Earth. In this biology lesson, students observe microbes under a microscope. They compare and contrast respiration and photosynthesis.
Curated OER
Can You Catch Your Breath?
Students apply the the scientific method to an investigation.They develop and perform a scientific procedure for determining lung capacity. In addition, they write a report to display information and share their procedures with the class.

How Smoking Affects Our Repiratory System
Seventh graders examine the dangers of smoking. In this life science lesson plan, 7th graders survey their schoolmates about the factors that would influence them to smoke. They present their findings in class by creating a presentation.
Curated OER
Experimenting with Yeast Metabolism
Ninth graders determine the rate of respiration by yeast and which sugars can be used as a food source by yeast using a CO2 gas sensor and computer software. This lesson is for an honors Biology class.
Curated OER
Egging It
Sixth graders discover scientific processes by conducting an experiment in class. In this osmosis instructional activity, 6th graders utilize eggs, cooking ingredients, string and plastic cups to create an experiment in which they watch...

How to Make a Model of the Human Respiratory System
Students label parts of the human respiratory system on a diagram. They explain the function of diaphragm.
Curated OER
De"compost"ition
Students develop an understanding of the decomposition process and the parameters which influence the rate at which it occurs.
Curated OER
I Wonder How Manduca Breathe
Students observe a Manduca bug as it is dropped in a glass of water and hypothesise how it breathes. They compare this to how humans and other creatures breathe and record their findings in their science journal.
Curated OER
Air, Air Everywhere! Lesson 2: Acid Rain
Middle school environmentalists record the pH of four different liquids, including two aerosol cleaning products. They liken the products to acid rain and speculate in writing which might affect the human respiratory system. Although...
