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.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut. Learners use a formula to calculate the calories in a peanut and then differentiate between food calories and physicist calories as well as calories and joules.

D-Lab Development addresses issues of technological improvements at the micro level for developing countries—in particular, how the quality of life of low-income households can be improved by adaptation of low cost and sustainable technologies. Discussion of development issues as well as project implementation challenges are addressed through lectures, case studies, guest speakers and laboratory exercises. Students form project teams to partner with mostly local level organizations in developing countries, and formulate plans for an IAP site visit. (Previous field sites include Ghana, Brazil, Honduras and India.) Project team meetings focus on developing specific projects and include cultural, social, political, environmental and economic overviews of the countries and localities to be visited as well as an introduction to the local languages.

How many calories are in your favorite foods? How much exercise would you have to do to burn off these calories? What is the relationship between calories and weight? Explore these issues by choosing diet and exercise and keeping an eye on your weight.

This activity gives students a way to look at how organisms are connected to ecosystems through the cycling of matter and the flow of energy. By the end of the activity, students will be able to make distinctions between how matter and energy are used and transferred and will be encouraged to apply this important crosscutting concept to the world around them.

First, students observe an animal, then they reflect on how it uses matter from food to build body structures and energy from food to do things. Students look at food as “packages” of matter and energy that animals (and plants) consume. They also think about wastes, such as poo, pee, sweat, heat, and carbon dioxide. This is a focused activity best used as part of an extended matter and energy-themed experience, and it works best after students have had time to explore, check out organisms in other ways, and be physically active.

Students learn about energy flow in food webs, including the roles of the sun, producers, consumers and decomposers in the energy cycle. They model a food web and create diagrams of food webs using their own drawings and/or images from nature or wildlife magazines. Students investigate the links between the sun, plants and animals, building their understanding of the web of nutrient dependency and energy transfer.

Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and decomposers. Students are introduced to the roles of the hydrologic (water), carbon, and nitrogen cycles in sustaining the worlds' ecosystems so living organisms survive. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Geography 430 is an active, creative learning community focused around understanding the changing relationships between people and their environments, the causes and consequences of environmental degradation, strategies for building a more sustainable world, and the methods and approaches that scholars have used to understand human-environment interactions. The primary course objectives are to help geographers, earth scientists, and other professionals to deepen their appreciation for the complexity of human-environment systems and to develop skills that allow them to interpret, analyze, and communicate effectively regarding human-environment interactions in their lives as students, professionals, and citizens.

Earth contains a variety of plants to provide food, medicine and, most importantly, energy sources for humans. In this lesson, students will categorize plants by their components and shapes. Additionally, they will learn the mechanisms behind the making of medicines and bio-fuels. It is important that the students have prior knowledge of the plant cell structures and functions. The video duration is 21 minutes, during which the students will use skills such as classification and experimentation. The students must therefore be supplied with various samples of plants.

Three short, hands-on, in-class demos expand students' understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, students create paper snake mobiles to explore how heat energy can cause motion. Finally, students determine the effect that heat energy from the sun (or a lamp) has on temperature by placing pans of water in different locations.
