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...

Learners identify photosynthesis as a process through which organisms make their own food. They practice the process for writing the formula for the photosynthesis equation. Students describe how the processes of photosynthesis and...

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...

How do plants and animals get their food? Learn about where energy comes from, how animals store energy, and aerobic respiration, in a lesson that allows scholars to diagram energy flows. 

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...

Learners 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...

Seventh graders cut and paste animal pictures to create a food web and trace the path of energy. They write a paragraph explaining the importance of photosynthesis in all food webs.

Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...

Students explore elements by analyzing everyday objects and materials in class. In this carbon instructional activity, students define several vocabulary terms such as carbon dioxide, hydrocarbon, and carbonate. Students view a group of...

Help learners find ways to become more efficient energy consumers. To start, individuals research how different countries address energy efficiency and then analyze their own carbon footprint. They use their research to identify ways to...

Students encounter the complexity of identifying the cause of unusual variations in WOW conductivity data. They propose theories on why there was a sudden increase in conductivity in Ice Lake, Minnesota during July of 1998.

Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.

High schoolers explore a variety of relevant lake water chemistry questions, compose responses, and present their results in a poster format. They, in pairs, answer questions about lake chemistry which are imbedded in this plan.

Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-instructional activity series in which students explore dissolved oxygen and then design an experiment testing the...

Students explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.
