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...

Respiratory, Circulatory, and Urogenital Systems in the Rat
Here is a instructional activity which describes a lab activity in which a rat is dissected, and its heart is studied. The instructional activity has ample background information about three of the rats internal systems, and excellent...
Baylor College
Lungometer
Life science learners construct lung-o-meters from gallon-sized milk jugs and then measure their lung capacities. For older students, have them graph the vital lung capacities of each person in the class. Cross-curricular pieces are...

Circulation and Respiration: Vital Signs
What do your vital signs tell your doctor? An engaging hands-on lesson plan has your learners monitor their own lung capacity, blood pressure, and heart rate. They then connect the vital measures to the workings of the circulatory and...
Curated OER
Organ Systems
Students examine organisms that are composed of tissues, organs, and systems. They dissect a fetal pig and explore the assigned organs systems such as the skeletal, muscular, and circulatory organs. Students identify and explain their...

The Breathtaking Nature of the Urban Explosion, Part 4
Pupils explore the respiratory system. They use a computer to monitor the respiratory rate of an individual. They determine residual oxygen levels in exhaled air. Students evaluate how internal 02 and C02 concentrations influence...

Graphing Toad/ Frog Respiration
Young scholars measure respiratory rates on live toads, and the effect water temperature has on their findings. For this scientific method lesson, students record their findings and present them in a graph, comparing the results.
