How will succession in two forest ecosystems: a recently de-glaciated area and an established temperate rainforest, vary? Objective Students will examine the differences in throughfall, litterfall, and soil condition the two forests sites. Students will learn to design an experiment to investigate a well thought out hypothesis. Students will gain an understanding of nutrient cycling in a forest. Students will understand how outside influences, natural or human-made, can interfere with this cycle. Background Teachers need to read the Succession (pg 75) and Temperate Rainforest (pg 77) sections Duration: 90 Minutes Additional Standards: NATIONAL STANDARDS: Science A 1,2, C 4, E 1, 2, F 2, 5, G 2.
