Science: What Is the Carbon Cycle?
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...
Curated OER
Producers and Energy Transfer
Fifth graders discuss the relationship between producers, consumers, and decomposers as they look at the energy pyramid. While working in small groups, they create an ecosystem that includes all or some of the given categories, and they...
Curated OER
How do plant & animal cells make and use energy?
Students show the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They see the flaws associated with this thinking because of the lack of CO2 and H2O and lack of sufficient gravity in order...
Curated OER
Photosynthesis: Intake of Carbon Dioxide - Production of Oxygen
High schoolers, after a long-term observation of photosynthesis with aquatic plants, assess the benefits of photosynthesis towards all living organisms. They explain in their own words the two cycles within photosynthesis. Guided...
Curated OER
Leaf Unit
Students complete a unit on leaves and their functions. They identify leaves and the trees they belong to, read various books, observe the process of photosynthesis on a flannel board, and create a leaf collage.
Curated OER
Sugar and carbohydrates, protein, fat and water - that's what little plants are made of!
Young scholars identify photosynthesis as the mechanism by which plants convert sunlight energy into a usable energy source for plant processes. They identify photosynthesis as the mechanism by which plants create a molecule that can be...
Curated OER
Photosynthesis
Sixth graders are introduced to the process of photosynthesis by discussion and then by participating in an experiment. They then answer questions as independent practice project.
Curated OER
Carbon Dioxide Exercise
Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five...
Curated OER
Forests and Photosynthesis
Fourth graders explore the concept of photosynthesis. They investigate the effects of light on seedlings. Students grow plants and record the data. Students view satellite images that show the monthly amount of vegetation present in the...
Curated OER
Using A Winogradsky Column to Analyze Microbial Communities
Students use easily obtained materials to study ecological succession in a microbiological community. This investigation is appropriate for a variety of age groups. Elementary Students be fascinated by the changes occurring over time...
Curated OER
Science: Leaf Study
First graders go on a leaf-hunting expedition around the schoolyard. They determine from which trees they fell using identification cards. Students read several books about leaves and apply their artistic skills by using the collected...
Curated OER
Researching Plant Life
Fourth graders examine the process of photosynthesis. Given websites about plant life, 4th graders retrieve and record accurate information about the parts of the plant and photosynthesis. Students solve a "Plant Life Mystery" from...
Curated OER
Fiber of Life
Students examine the importance of plants to individuals and society through a multi-discipline set of activities. They observe and draw different leaf structures and then create a book about trees and photosynthesis. They explore ways...
Curated OER
Explain Plant Chemical Processes
Students discover plant chemical processes through three lab activities. Overheads, data sheets, and teaching procedures provided for the unit covering photosynthesis, respiration, and transpiration.
Curated OER
Leaf Straw
Pupils investigate plant structure and the process of photosynthesis. Using everyday items, they demonstrate that the leaves and stems of plants can act like a straw. In addition, they identify plant structure.
Curated OER
Do Plants Eat?
Students explain that photosynthesis is a process that plants use to convert light energy into glucose. They summarize photosynthesis as a chemical process in which the plant uses carbon dioxide and water to form glucose and oxygen.
Curated OER
Food Webs
Students create a bulletin board display illustrating food chains they make from a list of ocean organisms. Students also play a game showing what happens when one of the organisms is removed from the food chain and how they are all...
Curated OER
Food Webs
Students recognize interdependence in a food web by using yarn and notecards to create a food web and discussing what would happen if one of the organisms from a certain trophic level is removed.
Curated OER
Photosynthesis With K'Nex
Students explore the process of photosynthesis. They create a diagram of photosynthesis, create a flower using K'NEX pieces and gears, and write a paragraph explaining how they would take care of their flower according to the process of...
