Students Explain how an increased level of activity translates to cells needing more oxygen and how the lungs supply this oxygen by entering the blood stream. They also can explain that the heart is responsible for moving both oxygenated...

Use demonstrations to enlighten learners on oxygen's role in combustion. Use potatoes and hydrogen peroxide to increase oxygen concentration in a jar, then stick a glowing splint and a burning wad of steel wool into the newly formed...

This presentation is about air. What makes it unique is that, in addition to simply providing information about the components of air and the action of air pressure, it  includes a series of four experiments that bring these...

Five questions are presented and answered as a means of delivering information on the respiratory system. Using red and blue game chips, physiology learners model the movement of blood through the lungs. Groups of learners time how long...

Guide high school meteorologists through a detailed examination of oxygen concentration data. The learners analyze a line graph containing logarithmic data and employ the use of a graphing calculator. A comprehensive worksheet and links...

Middle-school meteorologists absorb information about ultraviolet radiaton and consider the ozone layer. The book that learners are supposed to refer to is not available, so you might want to locate some graphics or posters...

Students engage in lesson concerned with the concept of the ozone layer. They write a reflective journal using prior knowledge. Students read sources of information about the existence of a hole in the ozone layer. Finally they create...

Students investigate photosynthesis in water plants. In this photosynthesis lesson plan, students use the elodea plant and observe gas bubbles released to determine the rate of photosynthesis. They vary the light intensity and the amount...

In this photosynthesis worksheet, students are given a diagram of photosynthesis and words that correlate with the process. They use the words to fill in the blanks about the process and the structures involved in photosynthesis.

In this gases worksheet, students conduct an experiment to produce 2 different gases and use standard tests to identify each gas. This worksheet has 14 short answer questions.

Third graders discuss how humans breathe and how plants help us to stay alive. In groups, they identify and label the different parts of plants and describe their functions. They compare and contrast the ways plants and animals breathe...

A pumpkin and a candle are all you need to help teach your students about what keep a flame going, and what factors lead to its going out. A lot of rich discussion should result from this fun activity. A great addition to a science...

In this compounds worksheet, students compare the differences between compounds and mixtures. This worksheet has 3 short answer questions.

Students are introduced to biomolecules and their roles in livin systems. They are introduced to the "Elements of Life." Students write down and define the "Elements of Life." They are asked why they think those elements are essential...

Young scholars discuss the process of photosynthesis in plants and that oxygen is produced as a by product. They observe underwater Elodea plants "breathing" in a hands-on activity. After setting up the experiment, they observe the...

Students observe teacher demonstration, discuss Fire Triangle, examine three things that fire needs to continue burning, including fuel, oxygen, and heat, and discuss how Stop, Drop, and Roll strategy is safest method of stopping...

First graders study the importance of trees to our environment. they make their own version of the story by completing the following sentence and then completing an illustration for their writing. "A tree can be ______."

Students explore the parts of the heart and how blood travels throughout the body. They conduct a simple simulation to demonstrate the path that blood takes through the body and the functions it performs.

Students exercise their muscles to explore concept of heart rate and to explain how blood supplies muscles with oxygen.

Students recognize the presence of organic matter in soils from their immediate area and recognize which soil sample contains the highest concentration of organic matter.

For this photosynthesis worksheet, students use a textbook to research the different scientists involved in the discovery of the process of photosynthesis. This worksheet has 31 fill in the blank questions.

Middle schoolers examine the role of carbon in the oceans and how phytoplankton determine the levels present. In groups, they practice measuring primary productivity using two methods. They use the internet to research the role of...

Second graders gain an understanding of how plants produce oxygen and that the oxygen we breathe comes from trees and plants. After a lecture/demo, 2nd graders discuss the ways plants produce oxygen and the detrimental effects of cutting...
