Four year-long project instructions for science students.

These are four projects my students have used from year 7 to year 10 for five consecutive years. It helps them develop independent learning, makes them take pride in their work, gives opportunity for assessment of another style of careful slow-paced work, and when returned provides them something they can keep as a nice souvenir of something they made while learning in Science. They include detailed instructions and visual examples for students to follow. They are ordered in level from the first (year 7) to the last (year 10).
