This unit on matter cycling and photosynthesis begins with students reflecting on what they ate for breakfast. Students are prompted to consider where their food comes from and consider which breakfast items might be from plants. Then students taste a common breakfast food, maple syrup, and see that according to the label, it is 100% from a tree.

Based on the preceding unit, students argue that they know what happens to the sugar in syrup when they consume it. It is absorbed into the circulatory system and transported to cells in their body to be used for fuel. Students explore what else is in food and discover that food from plants, like bananas, peanut butter, beans, avocado, and almonds, not only have sugars but proteins and fats as well. This discovery leads them to wonder how plants are getting these food molecules and where a plant’s food comes from.

Students figure out that they can trace all food back to plants, including processed and synthetic food. They obtain and communicate information to explain how matter gets from living things that have died back into the system through processes done by decomposers. Students finally explain that the pieces of their food are constantly recycled between living and nonliving parts of a system.

Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of central tendency of the class data, and then graph and interpret the results.

This simulation shows the relationship between the inputs and outputs in the chloroplasts of plants to help explain how they convert water and carbon dioxide to glucose and water with the help of energy absorbed from light. It is used in Lesson 5 of Unit 7.4 in the OpenSciEd curriculum.

This lesson is about the flow of energy in ecosystems. The setting is Plimoth Plantation, a living history museum in Plymouth, Massachusetts, USA, where students will learn about the first Thanksgiving meal in America, celebrated in 1621 by early American settlers and Wampanoag Indians. By examining this meal and comparing it to a modern day Thanksgiving celebration, students will be able to explore the way in which food energy moves and is transformed in an ecosystem. The learning goals focus on the movement of energy from one feeding level to the next within a food web, the way in which energy changes form, and the inefficiency of energy transfer, which in turn affects the availability of food energy for organisms at the highest feeding level. The lesson is directed at high school level biology students. Students should be familiar already with food webs, food chains, and trophic (feeding) levels. They should also be familiar with the general equations for photosynthesis (CO2 + H2O => C6H12O6) and cell respiration (C6H12O6 => CO2 + H2O), and understand the basic purpose of these processes in nature. This lesson can be completed during one long classroom period, or can be divided over two or more class meetings. The duration of the lesson will depend on prior knowledge of the students and on the amount of time allotted for student discussion. There are no supplies required for this lesson other than the downloadable worksheets (accessed on this BLOSSOMS site), paper and some glue or tape.

In this activity students will identify where the ingredients in a tomato and cheese sandwich originated. They will trace a food item from its place as a sandwich ingredient to where it was originally grown. Students then suggest ways that people can minimize their impact on ecosystems and biodiversity by making informed decisions about food choices.

Students look for (and document) evidence of the water cycle, photosynthesis, and decomposition in the schoolyard. Students should have prior experience with these processes before doing this activity. This activity can be used as a culminating activity for Lesson 3, Parts A-C.Students answer the essential question: What evidence of the water cycle, photosynthesis, and decomposition can we find in the schoolyard?

In this 7th grade science lesson, students review the structures and processes that allow flowering plants to reproduce, and then pick a flower from the garden to dissect and diagram.

In this 6th grade Science class, students learn how to build a compost pile, learn about organisms needed for decomposition, and begin to understand the purpose of compost in the garden.

The Ecology Student Edition book is one of ten volumes making up the Human Biology curriculum, an interdisciplinary and inquiry-based approach to the study of life science.

This wiki page documents the Sun Curve Design Challenge, inspired by the "Sun Curve" aquaponic garden sculpture to challenge teachers and students to produce new OER materials and incorporate green design thinking into the classroom.

Meg set out to climb up and investigate the rain forest tree canopies — and to be the first scientist to do so. But she encountered challenge after challenge. Male teachers would not let her into their classrooms, the high canopy was difficult to get to, and worst of all, people were logging and clearing the forests. Meg never gave up or gave in. She studied, invented, and persevered, not only creating a future for herself as a scientist, but making sure that the rainforests had a future as well. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenge: Your community has many different areas to explore - it might be a park, a grocery store, a forest, or an alley. For some people, it might be difficult to explore these areas because they may have differing abilities. Select one area in your community, and come up with a plan to build a way for it to be more accessible to everyone.

A document is included in the resources folder that lists the complete standards-alignment for this book activity.

CK-12 Life Science Honors For Middle School covers seven units: Understanding Living Things; Cells: The Building Blocks of Life; Genetics and Evolution; Prokaryotes, Protists, Fungi, and Plants; The Animal Kingdom; The Human Body; and Ecology.

In this group of activities, students will investigate how nutrients and water move through ecosystems in cycles. Students will begin by investigating how carbon cycles through organisms as part of photosynthesis and cellular respiration and then through food chains. Students will discuss what happens when living things do not decompose under normal conditions and become fossilfuels. Students will then review the water cycle and discover that water connects everything inecosystems. Students will explore stories of the water cycle as told by molecules of water anddiscuss water’s importance to all living things.

The true story of how Momofuko Ando was inspired to create one of the world’s most popular foods after seeing long lines of hungry people waiting for a simple bowl of ramen following World War II. He dreamed about making a new kind of ramen noodle soup that was quick, convenient, and tasty for the hungry people because he believed that peace follows from a hungry stomach. With persistence, creativity, and a little inspiration, Ando succeeded. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenge: Develop a food product (a new food, tool, or invention, et al) to help increase access to food in your community.

Students are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires, hurricanes and thunderstorms. They see how these natural events become disasters when they impact people, and how engineers help to make people safe from them. Students begin by learning about the structure of the Earth; they create clay models showing the Earth's layers, see a continental drift demo, calculate drift over time, and make fault models. They learn how earthquakes happen; they investigate the integrity of structural designs using model seismographs. Using toothpicks and mini-marshmallows, they create and test structures in a simulated earthquake on a tray of Jell-O. Students learn about the causes, composition and types of volcanoes, and watch and measure a class mock eruption demo, observing the phases that change a mountain's shape. Students learn that the different types of landslides are all are the result of gravity, friction and the materials involved. Using a small-scale model of a debris chute, they explore how landslides start in response to variables in material, slope and water content. Students learn about tsunamis, discovering what causes them and makes them so dangerous. Using a table-top-sized tsunami generator, they test how model structures of different material types fare in devastating waves. Students learn about the causes of floods, their benefits and potential for disaster. Using riverbed models made of clay in baking pans, students simulate the impact of different river volumes, floodplain terrain and levee designs in experimental trials. They learn about the basic characteristics, damage and occurrence of tornadoes, examining them closely by creating water vortices in soda bottles. They complete mock engineering analyses of tornado damage, analyze and graph US tornado damage data, and draw and present structure designs intended to withstand high winds.
