After being introduced to a stem and leaf plot, students will be able to create their own stem and leaf plots.
Teachers will find lesson plans, class activities, and web resources that integrate engineering projects into the classroom and that advance students' math and science skills. Teachers can expand their professional horizon by subscribing to a weekly newsletter, delivered by email, that contains K-12 education news, as well as new lesson plans and activities.
What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or the release of moisture to the atmosphere by plants.
Students gain an understanding of the parts of a plant, plant types and how they produce their own food from sunlight through photosynthesis. They also learn about transpiration, the process by which plants release moisture to the atmosphere. With this understanding, students test the effects of photosynthesis and transpiration by growing a plant from seed. They learn how plants play an important part in maintaining a balanced environment in which the living organisms of the Earth survive. This lesson is part of a series of six lessons in which students use their evolving understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
This lesson involves students in collecting data, organizing data into a line plot, discussing statistics, calculating mean, median and mode and consumer awareness.
This essay from the NOVA "Life's Greatest Miracle" Web site explores the debate over the use of embryonic stem cells in scientific research.
Introduction to stem and leaf plots.
The students will measure and record the length of their jumps. The lengths will be used to create a class stem and leaf plot.
Participatory seminar focuses on the knowledge and skills necessary for teaching science in higher education. Topics include: theories of adult learning; course development; promoting active learning, problem solving, and critical thinking in students; communicating with a diverse student body; using educational technology to further learning; lecturing; creating effective tests and assignments; and assessment and evaluation. Students research and present a relevant topic of particular interest. Subject is appropriate for both novices and those with teaching experience.
