Oyster Culture Cycle Worksheet
In this oyster culture cycle worksheet, students answer 31 questions about the six stages of the oyster culture cycle. They also answer questions about the oyster business.
Curated OER
What's Down There
Students write an essay about the coral reefs. In this oceanography lesson, students investigate the reef of Bonaire and compare it to reefs that are not thriving. Students then explore the differences that contribute to the overall...
Curated OER
Allelopathy Experiments
Learners explore how allelopathy works in plants. In this botany lesson plan, students explain how this phenomenon affect other organisms. They read and analyze an article about allelopathy and discuss its flaws.
