Second graders participate in a three part lesson in which they identify and describe forms of moisture in the environment. Part one of the lesson involves the three stages of the water cycle, part two focuses on creating humidity by...

Learners conduct a series of investigations on the unique properties of water. In this general science activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students investigate the circle of sea life by creating nitrogen compound models.  In this oceanography lesson, students discuss sea creatures and where their waste goes.  Students identify nitrogen cycles in the ocean by...

Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...

First graders identify the sun as a source of heat and light. They identify features of houses that help keep use sheltered and comfortable throughout daily and seasonal cycles. Students are told that summer is the best season to...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Students discuss places they have been where the air seemed hard to breathe. They discuss if they could "see" the humidity or smell. Students discuss ways this might relate to the fish in the aquarium. The teacher introduces pH and how...

Students create a model of the birth of a star and demonstrate the stages of the star's lifecycle.  In this star lifecycle instructional activity, students mix flour and water in a jar to model the birth of a star, then role-play...

Students study the Miller-Urey Experiment including its history and criticism.  In this origins of life lesson plan students repeat this experiment to see how it works.

Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...

Students explain in their own words how stars are formed. In this space science lesson, students summarize the life cycle of stars. They draw diagrams and label the step of the cycle they represent.

Pupils are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...

Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...

Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...

Students investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Students seek scientific and technological solutions to envrionmental problems. They record class activities in a journal. They identify relationships among living things and their environments.
