The process of fire requires oxygen, heat, and fuel. Take one of those away, and fire ceases to exist. That's the idea behind this instructional activity which portrays a candle burning inside an upside down jar. Pupils answer a couple...

Students diagram a plant. In this Science lesson, students explore the concept of photosynthesis focusing on the oxygen production. Students calculate the amount of plants needed to filter the air in their classroom.

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.

Students conduct experiments with plants.  In this photosynthesis lesson, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula for...

Fifth graders use modern technologies which allow them to gain a new, dynamic, and intersting understanding of themselves, their community, and the world. They focus on environmental education and the effect of the environment on plant...

Second graders measure red worms. In this lesson, 2nd graders observe and collect data on red worms. Students measure the red worms and create a graph with the data they collect.

Fourth graders are involved in a lab experience to look at the concept of heating up various materials to see how they react to an increase in temperature. They make observations and record them in a lab journal. Then students discuss...

In this fractions in chemistry worksheet, students solve 2 problems where they state all the answers as simple fractions or integers. They determine ratios of molecules in gasoline and they find ratio of molecules in the creation of...

Young scholars name the vessels and parts of the heart. They trace the path of blood through the heart. Students examine the function of the circulatory system. They recognize the differences between a hear when the body is at rest...

What does it mean to grow? To germinate? For the plan detailed here, class members investigate the growth process of an oak tree while focusing on the beginning stages of planting and germination. They plant seeds and record observations...

In this comet tails and stars worksheet, students read about the star Mira and the vast clouds of gases it emits. They use a photograph from the Galaxy Evolution Explorer satellite to solve 5 problems about the scale of the image, the...

Students compare and contrast cellular respiration in yeast and plant and animal cells. After discovering the role of yeast in making beer and bread, they describe the short and long term effects of alcohol on the nervous and digestive...

Students work together to compare and contrast Mars and Earth. Using the internet, they answer questions given to them by their teacher and calculate answers showing their work. They graph their answers and discuss the results of the...

Students identify the different parts of the respiratory system of the human body. They work together to complete an activity and worksheet about the effects of radon on the lungs. They research lung diseases if time permits.
