Acid Rain
Students use a pH sensor to measure the impact atmospheric pollutants have on rainfall and plant growth.
Respiration of Germinating Seeds
Students use a carbon dioxide gas sensor to explore the energy requirements of seeds moving from dormancy to germination.
Osmosis
Students use a pressure sensor to study the movement of water through a cell membrane model by osmosis.
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.
Enzyme Action - Pressure Sensor
Students use a pressure sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
Work and Kinetic Energy
How is the work done on an object by a force related to the change in that object's kinetic energy? Investigate the relationship between the change in...
Speed and Velocity Graphs
Use a Smart Cart to perform a conceptual exploration of graphs of speed versus velocity.
Momentum and Impulse
How is the impulse imparted to an object in a collision related to the change in momentum of the object? Investigate the relationship between the change...
Momentum and Explosions
How is the total momentum of a two-object system affected by an explosion? Experimentally determine if linear momentum is conserved in a system that experiences...
