In this tidal forces worksheet, students read about the gravitational pull from the moon that causes the ocean tides. Students solve 3 problems including finding the Roche or the tidal radius for the Earth and Moon, comparing the Roche Limit of Saturn to its ring system and finding the Roche Limit for the sun.
The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a population of bean seedlings and vary growth factors. When working with populations in your environmental studies or ecology class, this resource will provide plenty of material.
