Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson of an 11-part series. Then, they complete six investigations into the properties of oxygen.   

Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...

Here is an engaging and hands-on lesson plan that allows high school chemists to demonstrate the effects of a catalyst on various chemicals. They garner knowledge of how reactants and products differ from one another, while...

Finally, a photosynthesis activity that outshines the rest! Young biologists perform an experiment that allows them to observe photosynthesis through the production of oxygen. The lesson, part of the K20 series, also includes a study of...

What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

The third lesson in a series of 11 begins by using thermal decomposition of potassium chlorate to determine the mass percent of oxygen. Then a second activity allows scholars to demonstrate that the resulting residue is from a...

Act out the circulation of blood in the body with an innovative activity. Kids act as either body parts or blood, and carry necessary nutrients and waste throughout different stations to represent the way that oxygen circulates. 

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

Blow some bubbles and learn how living things need air in the eighth lesson of this series. Young scientists investigate this important gas by observing bubbles and monitoring their own breathing. A simple and fun activity that raises...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Imagine an ecosystem without any light or oxygen, where living things convert carbon dioxide into food. This ecosystem is thriving and might just be the largest ecosystem on our planet, yet we know very little about it. The lesson...

More asthma attacks happen at higher altitudes, but why? Scholars complete worksheets, learning about homeostasis and feedback related to breathing. Then, they work in small groups to experiment with breathing in limited amounts of...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Dracula isn't the only one who needs blood to survive. The eight-part unit includes seven lessons, five demonstrations, seven labs, and a project to organize a blood drive. Class members learn about the parts of...

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...

The carbon cycle isn't a bike which produces carbon and this lesson explains why. Through reading and discussion, groups of pupils create visual explanations of the four parts of the carbon dioxide oxygen cycle. Activities...

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...

How do plants and animals get their food? Learn about where energy comes from, how animals store energy, and aerobic respiration, in a lesson that allows scholars to diagram energy flows. 

Sometimes a little pressure isn't a bad thing! A collaborative instructional activity uses models to demonstrate how air pressure inflates and deflates the lungs. Participants use everyday materials to create models of the chest cavity...

Explore soil, genetic traits, natural resources, and pollution in a series of lessons that focus on biodiversity. Kids complete experiments to learn more about the importance of varied genes and organisms in an ecosystem.

Whether you are teaching environmental science in junior high or studying recycling in kindergarten, there is something for all in this set of lessons designed for environmental education. The 110-page packet comes with tips for...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Trees are the star of a three-step unit celebrating Arbor Day. Step one takes an in-depth look into the structure of a tree, the process of photosynthesis, and the benefits of the leafy giants. Step two challenges scholars to create a...

Photosynthesis seems nothing short of magic: a little carbon dioxide and water, add energy, and poof, you get food! A thorough, collaborative lesson plan teaches youth the process of photosynthesis thanks to a skit they perform with a...
