Instructional/Environmental Modifications
	The procedures used to accommodate the range of abilities in the classroom, including students with disabilities, limited English proficiency, or bilingual students:

The classroom environment had to be modified in the following ways:

• Computer laboratory to allow each team to have access to a computer
• Planetarium visit might be used to facilitate understanding of celestial relationships and movement by measuring and recording changes in the daily path of the sun
• Library to accommodate large groups for a seminar
• Work in teams. Provide extra help after school for questions

The Learning Experience as it stands is geared for average and higher academic performers and, would possibly be difficult for some students. However, this does not mean that it cannot be introduced to all level students with the knowledge that modifications can be made. All students can explore and understand the concept of " length of day". The topic is rich enough to allow teachers to adapt the activity to any level of understanding for their classes. Students can create a spreadsheet and use the graphing utility to create the graphs. The ideas of symmetry, range, and patterns can be used to describe the graphs. The earth’s revolution and hemispheres can also be taught on a basic level. The teacher will have a greater role in guiding their students with these ideas and helping them make the appropriate connections.

Ultimately, the teacher will decide on the appropriate depths of understanding. Versions of the project could easily be modified and reduced in scope. Students may need to stay in teams for the entire activity and instead of writing an in-depth report they could write journal entries, or present an oral report using a PowerPoint presentation, or create a book describing life in different hemispheres over time.
