Teaching Photosynthesis and Cell Respiration with …

In common experience, the term "adapting" usually refers to changes during an organism's lifetime. In contrast, evolutionary biologists use the term "adaptation" to refer to a heritable trait that increases fitness. To help students reconcile these different concepts, this activity introduces the concept of phenotypic plasticity (the ability of an organism to adapt to different environments within its lifetime). Questions guide students in analyzing how the balance between the advantages and disadvantages of a characteristic (e.g. an animal’s color) can vary in different circumstances, how phenotypic plasticity can be a heritable trait that can optimize fitness in a variable environment, and how natural selection can influence the amount of phenotypic plasticity in a population.

This minds-on, hands-on activity begins with analysis and discussion questions that develop student understanding of homeostasis and negative feedback, the difference between negative and positive feedback, and the cooperation between the respiratory and circulatory systems to provide O2 and remove CO2 for cells all over the body. Then, students carry out and analyze an experiment which investigates how rate and depth of breathing are affected by negative feedback regulation of blood levels of CO2 and O2. Finally, students formulate a question concerning effects of exercise on breathing, design and carry out a relevant experiment, analyze and interpret their data, and relate their results to homeostasis during exercise.

Here you will explore how plants harness the Sun’s energy in photosynthesis in order to make food.

Photosynthesis and Cellular Respiration – Understanding the Basics of Bioenergetics and Biosynthesis (revised 5/2017)

In this hands-on, minds-on activity students learn (1) how genes provide the instructions for making a protein via transcription and translation and (2) how genes influence characteristics such as albinism and sickle cell anemia. Students use simple paper models to simulate the molecular processes of transcription and translation. This activity also includes multiple figures, brief explanations, and questions, together with four recommended videos. You can use this activity to introduce students to transcription and translation or to reinforce and enhance student understanding. An alternative version omits the paper models ("From Gene to Protein via Transcription and Translation"; ). (NGSS)

These Teacher Notes summarize basic concepts and information related to energy, ATP, cellular respiration, and photosynthesis. These Teacher Notes also review common misconceptions and suggest a sequence of learning activities designed to develop student understanding of important concepts and overcome any misconceptions.

LabBench Activity Plant Pigments and Photosynthesis

This analysis and discussion activity introduces students to the basic principles of how biological organisms use energy. The focus is on understanding the roles of ATP and cellular respiration. In addition, students apply the principles of conservation of energy and conservation of matter to avoid common errors and correct common misconceptions. (NGSS)

HIV is spread by sexual contact or exchange of body fluids such as blood which occurs when drug users share needles.

Animation - Respiration and photosynthesis


The Link between Photosynthesis and Cellular Respiration -

In this minds-on activity, students analyze the relationships between photosynthesis, cellular respiration, and the production and use of ATP. Students learn that sugar molecules produced by photosynthesis are used for cellular respiration and for the synthesis of other organic molecules. Thus, photosynthesis contributes to plant metabolism and growth. The optional final section challenges students to explain observed changes in biomass for plants growing in the light vs. dark. (NGSS)

Connecting Photosynthesis and Cellular Respiration: …

In the first part of this activity, students learn how to use the floating leaf disk method to measure the rate of net photosynthesis (i.e. the rate of photosynthesis minus the rate of cellular respiration). They use this method to show that net photosynthesis occurs in leaf disks in a solution of sodium bicarbonate, but not in water. Questions guide students in reviewing the relevant biology and analyzing and interpreting their results. In the second part of this activity, student groups develop hypotheses about factors that influence the rate of net photosynthesis, and then each student group designs and carries out an investigation to test the effects of one of these factors. (NGSS)

BetterLesson - Photosynthesis and Cellular Respiration

This analysis and discussion activity helps students to understand the relationships between food, cellular respiration, energy, physical activity, and changes in body weight. At the end of the activity, each student asks and researches an additional question using recommended reliable internet sources. (NGSS)

Cellular Respiration & Photosynthesis Lesson Plans: ATP

Students learn how organic molecules move and are transformed in ecosystems as a result of the trophic relationships in food webs, photosynthesis, cellular respiration, and biosynthesis. This provides the basis for understanding carbon cycles and energy flow through ecosystems. In the final section, students use these concepts and quantitative reasoning to understand trophic pyramids. (NGSS).

Amy Brown Science: Teaching Cellular Respiration

In this hands-on, minds-on activity students use model chromosomes and answer analysis and discussion questions to learn how mitosis ensures that each new cell gets a complete set of genes. Students also learn how genes on chromosomes influence phenotypic characteristics and how a single cell develops into the trillions of cells in a human body. This activity can be used to introduce mitosis or to reinforce student understanding of mitosis. (NGSS)
