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.
Organisms and pH
Students use a pH sensor to determine how effective various substances are at resisting large changes in pH.
Membrane Permeability (pH sensor)
Students use a pH sensor to explore which substances can and cannot pass through a cell membrane model.
Enzyme Action - Oxygen Sensor
Students use an oxygen sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
