Students observe one of the direct effects of acid water on plant growth. Students engage in an experiment which will take about 2 weeks. Students will understand the effect that acid rain has on plant growth.

Students observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.

Students perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.

Students' recognize the various roles of predicting in science. Students' practice making and interpreting predictions; experimenting to test their hypotheses; and refine their predictions based on observation and experimentation....

Students engage in a lesson to determine the source of water that is used. They conduct research using a variety of resources. The lesson includes information for the teacher to share with the class. Students write and define the...

It's shark week! In this problem, young mathematically minded marine biologists need to study the fish population by analyzing data over time. The emphasis is on understanding the average rate of change of the population and drawing...

Explore the current political debate over regulating power plant emissions. Critical thinkers research, formulate, and present arguments regarding selective catalytic reduction systems for coal-burning plants.

Learners brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity...

Students observe air quality and monoxide data. For this air quality lesson, students draw conclusions and manipulate data from a one year period on changes in air quality.

After reading about the amount of energy that is used to power a personal computer, learners take a look at their own computer use and therefore, their energy consumption. They do this through a series of questions and computations on...

Look around and explore. Little ones use their five senses with some day-to-day activities designed to guide observation and apply STEM strategies. Young scientists learn through comparing/contrasting and...

Students describe, orally or in writing, ways people have depended on water during different periods of history. This nearly 500 page document is rich with diverse lessons and activities that will transform your young learners into...

Students examine the relationship between hazardous substances and hazardous waste. They identify toxic chemicals and how they are disposed of. They work together to answer questions about how they are improperly used.

Students participate in an activity to examine the concept of risk. They discover that not all risks have the same consequences. They work together to complete a worksheet on probability and their perceptions.

Students work together to develop and write scenerios for the future of hazardous waste cleanup. They share their scenerios with the class. They complete activities as well.

Students work together to examine water quality. They identify the indicators of water quality and complete an experiment. They discuss their results.

Students work together to discover the path water follows in plants. They create multicolored flowers. They label each part of the plant and note their function.

Students examine the components of soil. They work together to use different materials to create their own soil. They make their own dirt cake as well.

Young scholars examine the concept of transpiration. They work together to complete an experiment in which they see water loss in plants. They record their observations and discuss their conclusions.

Students examine the role of micro and macro organisms in the decomposition process. They record their observations and discuss. They also read a book about decomposition.

Young scholars work together to discover the relationship between water holding and drainage characteristics of soils. They record their observations and discuss the results. They examine particle size and pore sizes as well.

Learners examine the decomposition process. They create their own class compost pile and record their observations. They discover which materials decompose at a different rate.

Students work together to make recycled paper. They identify examples of recycled materials and discover what can and cannot be recycled. They explore the history of paper making as well.

Students study the structure and function of the parts of a winter twig. They determine how to identify trees using the twigs.
