History's Thermometers
How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...
NOAA
The Dead Zone
The fifth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program defines dead zones and how they form. Pupils then examine data from the Gulf of Mexico to determine dead zone formation.

Electrolysis Using a Microscale Hoffman Apparatus—Microscale Chemistry
Get big results out of a small-scale lab! Young chemists observe the electrolysis of sodium sulfate using a microscale experiment. A colorful indicator solution combined with the production of gas bubbles yields a variety of observations...
Curated OER
Wind and Wildfire
Emerging scientists research weather-related vocabulary terms, and map out where wildfires are most likely to occur. To bring this lesson to life, you could demonstrate what happens to a fire when you cool or remove the fuel, or cut off...
Curated OER
Stoichiometry (gases and masses)
In this chemistry worksheet, students identify how many liters of oxygen can be consumed to form carbon dioxide. Then they identify how many liters of sulfur dioxide are produced if the gas is at STP.
Baylor College
About Air
Give your class a colorful and tasty representation of the components of the mixture that we call air. Pop a few batches of popcorn in four different colors, one to represent each gas: nitrogen, oxygen, argon, and carbon dioxide. The...
Will Steger Foundation
The Carbon Cycle - What are its Implications for Climate Policy?
The carbon cycle isn't a bike which produces carbon and this instructional activity explains why. Through reading and discussion, groups of pupils create visual explanations of the four parts of the carbon dioxide oxygen cycle....
Omaha Zoo
Monitoring Amphibians
What sort of shoes do frogs wear? Open toad sandals. If your scholars want experience collecting field samples, this is the lesson for you. After learning the proper way to collect field samples, pupils catch amphibians to test for...

Consumers Get Energy From Other Living Things
How do plants and animals get their food? Learn about where energy comes from, how animals store energy, and aerobic respiration, in a instructional activity that allows scholars to diagram energy flows.
Concord Consortium
Polarization
This is one cool resource for teaching about polarity! Chemistry scholars observe electron distribution and molecular shape as they select different non-metals and form bonds. The interactive offers two views, surface charge and electron...
Curated OER
Observing the Elements of Water
Fifth graders conduct a closed circuit experiment to observe the elements of water. They discuss the elements of Hydrogen and Oxygen, and in small groups construct a closed circuit connected to two pencils placed in water. Students...
Curated OER
Yeast and Respiration
Students explore oxygen properties by conducting a cell experiment in class. In this respiration lesson, students discuss the process of breathing and how oxygen is inhaled before carbon dioxide is exhaled. Students utilize yeast, water,...
Curated OER
History's Thermometers
Learners explain the concept of paleoclimatological proxies. In this oxygen isotope lesson, students interpret data and make inferences about climate changes in the geologic past.
Curated OER
Cardiac Maze
Students participate in a role-play activity to lean about red and white blood cells, veins, capillaries and arteries. They also see how blood passes through the heart, lungs and out of the body, carrying oxygen and nutrients.
Curated OER
Body and Blood
Students explore the cardiovascular system. Through the use of video, students observe the heart pumping an oxygen-enriched blood supply through arteries to the muscles in use during exercise. They participate in activities to explore...
Curated OER
Finding the Formula of Magnesium Oxide
In this formula for magnesium oxide learning exercise, learners perform an oxidation reaction between magnesium and the oxygen in the air to produce magnesium oxide. Using the known masses of the magnesium and the end product, students...
Curated OER
Household Chemistry
Young scholars use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as...
Curated OER
The Energy Debate - Stoichiometry
Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.
Curated OER
Save Your Breath
Students discuss metabolism. In this metabolism lesson, students evaluate evidence form a research report and discuss the basis for hypothetical metabolic adaptations to low-oxygen environments in the anchialine caves.
Curated OER
Monitoring Estuarine Water Quality
Students analyze water quality data from real data. In this environmental science lesson, students examine how salinity and dissolved oxygen affect the living organisms in the estuary. They interpret graphs to support or disprove a...
Curated OER
Great Lakes Ecology
High schoolers are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier...
Curated OER
Freshwater Fish Water Quality
Sixth graders work together to complete an experiment about the quality of freshwater. In groups, they collect fresh water samples from a variety of sources and test the pH levels. After completing a KWL chart, they test the amout of...
