Third graders, in groups, classify different activities as aerobic or anaerobic. They create posters displaying their categorizations and then take notes on each other's posters.

In this lake worksheet, students access a website to read about how the conditions in a lake change during the seasons. Students write these changes in a graphic organizer.

Students use data from the Chesapeake Bay to analyze temperature, phosphate, nitrates, salinity, and oxygen levels.

Students explore the respiration rate of a mealworm. Through experimental means, they determine the average volume of oxygen used and discuss factors that affect the respiration rate of an organism.

Students study the gas exchanges that occur during cellular respiration. They observe what happens as a result of a number of variables on the rate of respiration. They use microrespirometers to measure the oxygen consumption of...

Students conduct three tests of water quality that can be utilized with TerrAqua columns and outdoors: pH, dissolved oxygen, and temperature. They make comparisons between different types of water and draw conclusions about how healthy...

In this chemistry activity, students write the balanced chemical equation for each. Then they calculate the mass of nitrogen dioxide created with specific amounts of nitrogen and oxygen. Students also identify how many grams of the...

In this photosynthesis and respiration worksheet, students will explore the function of the stomata on plant leaves Students will write the photosynthesis equation and label a diagram showing the movement of water, carbon dioxide, and...

In this word search learning exercise, students locate words related to earth science. The word list includes nitrogen, oxygen, sea breeze, atmosphere, and during the day.

In this word search worksheet, students locate 15 words related to science. The word list includes oxygen, reproduction, growth, and transport.

Students explore practical problems that are related to scuba diving.  In this oxygen activity students complete a lab activity. 

In this body systems worksheet, students complete a word equation for respiration. Students draw and label the human respiratory system. Students draw a diagram of the movement of oxygen and carbon dioxide in the air sacs.

Learners explore hypoxic (low oxygen) conditions in the Gulf of Mexico.  In this ocean habitat lesson, students hypothesis, design and implement an experiment to explain the existence of the "Dead Zone" in the Gulf of Mexico.

Learners investigate energy by researching how oil reservoirs work. In this fossil fuels lesson, students conduct an experiment using a half full bottle of water, corn oil and oxygen, recording their data as the elements are mixed...

Sixth graders discover scientific processes by conducting an experiment in class. In this osmosis lesson, 6th graders utilize eggs, cooking ingredients, string and plastic cups to create an experiment in which they watch the exchange of...

In this chemistry instructional activity, students solve various problems on stoichiometry by following what each statement describes. They identify how many moles and grams of carbon dioxide will be produced and what the theoretical...

Students mode the transport of blood through the circulatory system with a water relay. For this circulation lesson, students measure amounts of water and transfer them from one container to another. They use this activity to model the...

Students examine the following concepts: If water supplies contain materials which rot or decompose, oxygen is used. Decay and decomposition require vast supplies of oxygen. The use of oxygen for decay of wastes may be a life or death...

Students graph dissolved oxygen versus depth using data taken from NECOP Program. In this marine science instructional activity, students explain the causes of hypoxia. They recommend possible solutions to this problem.

High schoolers evaluate the relationship between oxygen levels and the amount of organic matter in an aquatic ecosystem. They explain the relationship between oxygen levels, bacteria and the breakdown of organic matter using an indicator...

Third graders examine how trees produce oxygen. They examine satellite images of the reservation they examining and interpret the number of trees on the land. They determine how natural resources should be used wisely.

Young scholars examine the effects of nitrates and phosphates on the dissolved oxygen levels in different water sources. In this series of 3 lessons, they consider the reasons for nitrate and phosphate level increases and their effects...

Students explore the basics of interpreting RUSS temperature and oxygen profile data. They are introduced to the Geographic Information Systems (GIS), particularly with respect to interpreting maps.

Students examine the role of human respiration and how it relates to radon. They identify damage to the lung from the exchange of carbon dioxide and oxygen. They work together to complete a lab activity and worksheet.
