Handouts
If there are simple written instructions that students would use during this activity they should be placed here and they can be cut and pasted into a word processing document for printing. There are mechanisms within this web format to upload pictures, tables, and more complex documents with diagrams. Common MS Office documents cannot be uploaded without first making modifications. Please link to tips on preparing handouts for upload.

Description of activity
Briefly describe the activity, but provide enough detail so that the activity can easily be assessed by other teachers without your intimate knowledge of the topic.

Lesson plan
An ordered account of how the lesson might proceed. It is worth recognizing that some flexibility is useful in lesson plans, but at the same time having a structure and direction provides some organization and structure that your students will appreciate. A bullet list may be the best format for some projects, but a few paragraphs may work just as well. Build in enough time for students to clean up after themselves and restock the program box for future students. Keep in mind that teachers are very busy, and a student clean up policy is essential for sanity.
