Middle schoolers are able to describe the importance of wetland vegetation. They describe the impacts human activities have on water systems. Students compare and contrast the effect of different soil types on water filtration.

Students perform experiments to determine the nutritional needs and physical space requirements for slime mold to survive. After formulating hypotheses, they seal the petri dishes and set up the experiment along with two controls. ...

Fourth graders are introduced to the concept of ecosystem; specifically, the interrelationships among plants and animals within an ecosystem, and their relationships to the environment in which they live and interact.

Students investigate the relationships between protozoa, algae and monera in freshwater, shoreline soil, and reindeer rumen. They publish reports of their findings.

Students use "Kid Pix" to explore plants. In this science and technology lesson plan, students become familiar with plant parts and label them on a plant. Students tell the functions of each of the plant parts.

Students explore how climatic factors influence the growth of plants. They create an experiment to find how variations in water, light, and temperature affect plant growth and describe how precipitation and geography can affect the...

Third graders research the interdependence of communities within different countries. In this community lesson, 3rd graders create a new community from a preselected country in South America. Students use the findings from their research...

Students consider the best place to plant a tree. In this environment lesson, students identify urban locations that are compatible with particular tree types. Students decide what trees would go where and why they would survive.

Students consider the increase in floods. In this current events lesson, students visit selected websites to research the occurance of floods in Britain.

Students research various forms of alternative energy sources and examine the pros and cons of each type. They discuss American oil dependence and the Bush administration's policies regarding this issue.

Students observe embryogenesis in action through early stages of development of eggs. They observe cultures with dissecting and compound microscopes. They draw their egg, record any details and observe for changes. They compare their...

Young scholars evaluate and interpret flood data from Central Texas. They list the tributaries that feed into the Guadalupe River and explain why is it important to include the tributaries in a discussion of the river, especially a...

Middle schoolers compare ways in which people form different cultures think about and deal with their physical environment and social conditions. They identify examples of change and recognize examples of cause and effect relationships....

Middle schoolers calculate averages of climate sets of data. In this ecology instructional activity, students analyze data to determine identity of a biome and collect meteorological data to understand process.  Middle schoolers...

Learners interactively explore the term transpiration. For this science/ecology lesson, students discuss what they would do if they were thirsty while conducting research in Brazil. Additionally, learners write descriptive words to...

Students identify the factors that affect viscosity of substances. In this chemistry lesson, students define what viscosity is in their own words. They give real world applications of viscosity.

Students list characteristics of wetland and describe the functions of a wetland.

Students examine the world of forensic science, focusing on fingerprint analysis. In the lesson, they implement a method by which fingerprints of class members are categorized and identified. Elementary students study classification...

Learners list four ways to identify trees. In this tree identification instructional activity, students use tree identification techniques such as leafs, bark, wood grain, soil type, and climate to create tables and graphs.

Students read a thermometer accurately, collect and record data, and generate a graph based on data. They learn what independent and dependent variables are. They analyze data and make conclusions concerning how soil coverings affect...

Students design and perform an experiment related to comparing and contrasting antlion pits. Given a set of parameters, students select a hypothesis and perform observations on antlion pits. They record data and use this date to support...

Students form groups to conduct an experiment. They plant seedlings to test the effects of sunlight, water and soil, on the growth of seedlings.

Identify agricultural products grown in each region of the country. Discuss how geography affects what is grown or raised in a particular area.1. Hand out a copy of the two activity sheets "Food From Sea to Shining Sea" to each student....

Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.
