AP Biology Lab Review
A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...
Curated OER
Science: Dissolved Oxygen and Water Quality Sampling
Students perform tests to determine the level of oxygen dissolved in water. After examining a table displaying the temperature and solubility of water, they examine the three stages involved in the test. Upon completion, students explain...
Curated OER
Dissolved Oxygen Lesson
Learners investigate what dissolved oxygen is and why it is important to aquatic life and what factors influence levels of dissolved oxygen in a lake. They study how to use MS Excel to make charts to show trends and correlations.
Curated OER
Roots Need Oxygen
Students investigate the growth of plants in soil with oxygen and soil without oxygen. They discuss what roots need to survive, and chart the growth of two plants to analyze the difference between plain soil and soil with two earthworms.
Curated OER
Secret Agents of Dissolved Oxygen
Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...
Curated OER
Plant Life
Seventh graders examine different categories of plant life and their roles as producers of food and oxygen for other organisms. They study the evolution of plants from simple organisms to very complex ones. They look at the different...
Curated OER
Investigation of Crystallinity in Polymeric Materials
A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...
