Water Quality and Temperature

Could the seasons be changing? Using National Park data, learners recognize patterns in the growth of seasonal plants. They look specifically at the first bloom date of cherry blossoms in Washington DC and compare them to temperature...

You will need a photovoltaic system and monitor at your school in order to obtain all of the data required to thoroughly implement this instructional activity. Your class monitors daily temperature and insolation amounts over a two week...

Study everything about plants! The 12-part series of lessons continues with an examination of many aspects of plants. Components of the laboratory activity address the growth and structure of plants by evaluating familiar plants. The...

This plant structure and function PowerPoint addresses the main organs and the factors that affect its development as well as going into detail about the specializations at a cellular level.   The cell functions and system...

Students investigate the effects of soil temperature, water availability, photo period and other variables of the growth of purple loosestrife. They observe the growing conditions of plants and alter them by adding water, isolating the...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Middle schoolers examine the growth of marigolds in a greenhouse environment. They chart data in spreadsheets showing plant growth over time and under a number of conditions. They record measures of plant height and greenhouse temperature.

Students construct a defined plot on school grounds and observed patterns in plant life. They count trees, shrubs, cacti and record on a data sheet. They compare data and generate a plant diversity overlook for their school.

Students correlate graphs of vegetation vigor with those of temperature and precipitation data for four diverse ecosystems, ranging from those near the equator to the poles, to determine which climatic factor is limiting growth.

Students investigate the effects of air temperature on seed germination by preparing seeds for germination and placing them in locations of varying temperatures. Students will monitor and record data concerning the temperatures and...
