An educational instructional activity focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

From the scientific method to the function of a cell, the eBook has it all. A useful resource provides a free biology textbook with a focus on context. The text begins with an overview of the process of scientific inquiry and biology...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

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.

Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-lesson series. Building on prior knowledge about producers, consumers, and decomposers students are introduced to the...

Jump into an exploration of marine ecosystems with the first lesson in this four-part series. After first learning about crustaceans, mollusks, and other forms of sea life, young marine biologists view a PowerPoint presentation that...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Young scientists learn what it takes for life on Earth to survive with this series of photosynthesis resources. Offering twelve different activities ranging from independent practice worksheets to in depth scientific...

Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

A simple, yet effective classroom activity is described in this resource on leaves and how they grow. The activity should lead pupils to discover how plants make their own food and what they need to survive. In the activity, they create...

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...

In this photosynthesis worksheet, pupils complete a crossword puzzle with 26 questions on the processes involved in photosynthesis.

Middle schoolers gather leaves and trace them on graph paper. They plot coordinates that approximate the shape of the leaves and share those coordinates as "worksheets" for other students to complete.

Students measure the weight of a container of leaves daily to discover how quickly it grows lighter as the foliage dries.

Fourteen questions about photosynthesis are presented for life science learners. First, they write out the names of compounds involved in the process. They answer a few questions, and then fill in the blanks. This concise assignment...

Fifteen multiple choice questions review a variety of biology topics. In game-show fashion, viewers answer questions about a plant's needs, the skeletal system, and the cardiovascular system. If you happen to teach these three topics...

Fifth graders participate in scientific inquires regarding the concepts of photosynthesis and cell respiration. In this photosynthesis and cell respiration lesson, 5th graders describe the process of photosynthesis with relation to...

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. 

Students explore coral reef ecosystems.  In this ecosystems science lesson, students research coral reef ecosystems to determine the major functions the participating organisms must perform.  Students construct a miniature...

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...

Learners test their local aquatic site to determine its water clarity. They collect a water sample and measure its turbidity using a sensor, then they repeat the experiment to obtain a second turbidity reading to find the average value.

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...

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...
