## Ecosystems

Students will discover differences within three different ecosystems through observation by using AppleWorks.

### Objectives

• Students will know that there are many different plants and animals living in many different kinds of environments by observing similarities and differences within several different environments within their community.
• Students will understand the concrete representation of quarter percents by figuring out the amount of dirt in their plot of land.
• Students will use an estimation strategy and determine the reasonableness of the results by estimating the amount of grass in the whole plot.
• Students will solve a problem by generating, collecting, organizing, displaying, and analyzing data using a bar graph.
• Students will create an expository response in which ideas and details follow an organizational pattern and are relavent to the purpose by writing a report based on their observations and data.

### Procedure

• Create one foot by one foot plots of land in three different ecosystems (one each day of the project).
• Partner students and have them follow the directions on the worksheet.
• Collect the data and enter it into the chart.
• Generate a chart from the data in the chart.
• After the three days of data collection, write a paragraph about each ecosystem using the observations and data. Also write a paragraph comparing the three ecosystems.

### NETS Profiles for Technology Literate Students

• Use keyboards and other common input and output devices (including adaptive devices when necessary) efficiently and effectively.
• Discuss common uses of technology in daily life and the advantages and disadvantages those uses provide.
• Use general purpose productivity tools and peripherals to support personal productivity, remediate skill deficits, and facilitate learning throughout the curriculum.
• Use technology resources (e.g., calculators, data collection probes, videos, educational software) for problem solving, self-directed learning, and extended learning activities.
• Evaluate the accuracy, relevance, appropriateness, comprehensiveness, and bias of electronic information sources.

### Materials

• iBook or a wireless computer
• AppleWorks

### Alternatives/Extensions

• Scan a living and non-living item from their plot to share with their presentation.
