This is a fun, hands-on activity in which students use physical properties to separate a mixture of sand, salt, seeds, and iron. After they've separated the mixture, they'll use percent error to evaluate their success and will write a lab report documenting their procedures and results.
This lab fits in particularly well with the study of the properties of matter and the classification of matter into mixtures and pure substances.
The following documents are included:
1) the lesson plan (2 pages)
2) the lab handout for students (2 pages)
3) the instructions for the lab report (student handout, 1 page)
4) the grading rubric for the lab report (1 page)
