Soil pH
Students use a pH sensor to investigate how local soil quality may impact the ability to support agricultural crops.
Photosynthesis of Aquatic Plants
Students use an optical dissolved oxygen sensor and a photosynthesis tank to study the photosynthetic rate of aquatic plants under different light conditions.
Metabolism of Yeast
Students use a carbon dioxide sensor to compare the metabolic rate of yeast in aerobic and anaerobic conditions.
Energy Content of Food
Students use a wireless temperature link and a fast response temperature probe to compare the amount of energy available from different food sources.
Cellular Respiration in Yeast
Students use an optical dissolved oxygen sensor and a fast response temperature probe to investigate the effect of temperature on the cellular respiration...
Acid Rain
Students use a pH sensor to measure the impact atmospheric pollutants have on rainfall and plant growth.
Buffers in Biological Systems
Students use a pH sensor to explore the effect buffers have on the ability of a cell to maintain homeostasis
Respiration of Germinating Seeds
Students use a carbon dioxide gas sensor to explore the energy requirements of seeds moving from dormancy to germination.
Plant Respiration and Photosynthesis
Students use a carbon dioxide gas sensor to measure the rates of photosynthesis and respiration in spinach leaves.
Osmosis
Students use a pressure sensor to study the movement of water through a cell membrane model by osmosis.
