Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Kids love superheroes, and for this assignment they create a comic about Captain Oxygen! Direct your class to make sure that their knowledge of the respiratory system is displayed through the dialogue. Note that though the publisher has...

This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

Students describe the relationship between exercise and health. They name ways to monitor their health and the equipment used to do so. Students name solutions to common health issues and explain why good nutrition and exercise are...

Ninth graders examine the structure and function of biomolecules. In this food molecule lesson, 9th graders will examine various  types of biomolecules such as  carbohydrates, lipids, proteins, and nucleic acids. They will...

Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...

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...

Students examine the differences between cellular respiration and photosynthesis.  In this cellular processes lesson students complete a group lab activity to see how climate change affects their lives. 

Young learners compare the breathing patterns of different animals in this pinniped lesson. They examine the breathing pattern of California sea lions and northern elephant seals. Pupils collect, compare and analyze data concerning...

In this carbon cycle lesson, middle schoolers review the carbon cycle and visit stations in the room where they experience every phase in the carbon cycle. Students journal about their journey through the cycle and brainstorm ways...

Students explore the processes of photosynthesis and respiration. For this photosynthesis and respiration lesson plan, students learn about the role of the chloroplasts in photosynthesis and about the role of mitochondria in respiration...

In this science worksheet, students answer 14 questions about respiration. For example, "Cellular Respiration starts off with..."

Young scholars identify that yeast are a single celled fungi that are a great model organism for studying respiration in the classroom. They also fill the bulb of a disposable pipet (eyedropper) with yeast, then submerge the pipet in a...

Students examine the carbon cycle while identifying its sources, sinks, and release agents. Using magazines and newspapers, groups of students design collages illustrating the carbon cycle. Finally, they write responses to several...

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 apply the the scientific method to an investigation.They develop and perform a scientific procedure for determining lung capacity. In addition, they write a report to display information and share their procedures with the class.

Students examine the disease Cystic fibrosis, the causes, and the effects it has on the respiratory system. Students use the Biology Workbench and tools on the National Center for Biotechnology Information website to study the protein...

Students explore respiration in a lake ecosystem by experiment and research.
